PENTAFLEX®

Design and construction of components impermeable to water* Fundamentals of sealing technology according to WU (water impermeable) guidelines In order to prevent ingress of water into structures, water impermeable reinforced steel structures, so-called "white tanks", have been fabricated for over 30 years. Thanks to these long years of practice and experience,

this method of construction represents an economical way of stopping the ingress of water. Furthermore, the WU guidelines represent the generally recognized current technical standard with regard to the "white tank".

The watertightness of a structure is characterised by the limitation of water ingress through concrete, construction joints and precrack dummy sections, mounting parts and cracks.

Method of construction with limited crack width: The method of construction with crack width limitation applies as the second approach to the solution. In this case, an increased reinforcement content of the concrete construction controls, or limits, the crack width.

Method of construction with subsequent sealing: In the case of the third method of construction, no special measures are introduced prior to the construction and formation of the cracks channelling the water are accepted. Later these are tightly sealed in accordance with the relevant guidelines. However, this method of construction may not be used for residential buildings.

This means: „„Sealed construction of all joints „„Meeting high requirements of the concrete „„Maintaining the minimum thickness for structural elements „„Crack limitation in structural components „„Maintaining a minimum height of the pressure zone „„Methodical arrangement and design of construction joints or sections of the pre-crack dummies if crack formation is expected

Design basics Construction method with decreased force stressing: Force stressing on concrete that can lead to water-channeling cracks is reduced by suitable constructional, concrete-related technical and design measures. As part of this are, e.g. level undersides on floor slabs with a layer of film, use of concrete receptors with low development of hydration and heating and extended after-treatment measures.

Design and construction of components impermeable to water* Design objectives A design of the arrangements must be carried out and the defined designs documented. For designs in accordance with WU guidelines, close collaboration between the different design areas is necessary. The following are the participants: „„Object designer/architect „„Geo-technician (if required) „„Bearing structure designer/WU designer „„Successful tenderer scheduling)

(work

„„In agreement with the construction participants depending on the complexity of the project: concrete „„technologist, construction physicist, building engineering designer.

The function and required utilisation of the structure, together with the regulations regarding fitness for purpose must be defined and documented. The following points must be clarified: „„Impact: the stress on the structure as a result of standing water or soil humidity „„Utilisation: which requirements need to be met by the structure in regard to impermeability to water The result of the first two design stages form the basis for further design measures. The impermeability to water of a structural element is determined by several factors.

The following points are to be accounted for in detail, both individually and in their combined effect: „„Selection of the concrete „„Dimensions of the structural components and reinforcement channels „„Avoidance or sealing of cracks or limitation of the crack width „„Planning of all joints and penetrations „„Planning of construction sequence, concreting sections, construction joints and sections of the pre-crack dummies „„Where necessary, account must be taken of aggressive water and soil. The concreting work, the after-treatment and the structure monitoring must be executed in accordance with DIN 1045-3.

Defining the WU guidelines The WU guidelines determine and define the specifications for

concrete structures impermeable to water. These are regulated

in relationship to the stress and utilisation classes.

Stress class There are two stress classes. They are differentiated by whether the flow of water is directly on the structure or the concern is only with soil humidity or, as the case may be, with seepage water.

Utilisation class The WU guidelines differentiate between two utilisation classes. They are dependent on the

function of the structure and the requirements on the thickness, and must be defined accordingly.

„„Stress class 1: for pressurised and non-pressurised water as well as intermittently trapped seepage water „„Stress class 2: for soil humidity and non-trapped seepage water

Utilisation class A ■■ No water passage in flowing form ■■ No points of humidity on the surface ■■ No cracks and joints channelling water Application examples: Residential building, storerooms with high-grade utilisation

Utilisation class B ■■ Areas of humidity permissible ■■ From temporary up to self-healing water-carrying cracks permitted ■■ No gathering of water on the surface Application examples: Underground car parks, installation and supply shafts, storerooms with low-level requirements

Design and construction of components impermeable to water* Requirements on the concrete In the selection of a suitable concrete it should be noted that, in addition to the requirements arising from the exposure classes from DIN 1045 pertaining to the structural component, the requirements on a concrete with high resistance to water ingress must also be satisfied.

A sufficient workability can be guaranteed by the consistency class F3 or softer. In the design of WU structural components in the minimum component thicknesses, a water/cement ratio of ≤ 0.55 and for walls, in addition, a largest particle size of ≤ 16 mm, must be used for stress class 1.

For a head of more than 1.0 m (e.g. for walls) an attachment mixture (largest particle ≤ 8 mm) must be used in the foot area at a height of ≥ 300 mm, in order to ensure a zero defect installation of the concrete.

Structural component thickness From many years of experience with concrete structural cast in-situ and pre-cast components, the following minimum thicknesses for the structural components are specified in the WU guidelines: Minimum thickness in mm

The minimum thickness and construction of the structural components must be selected such that the concrete structural components can be concreted technically correctly whilst adhering to the concrete cover, the required reinforcement location, joint sealing and the mounting components. In addition to all the other required features, it must also be possible to fulfil the support and sealing function.

Over and above the minimum dimensions, the following apply to the clearance dimension bW,i between the reinforcement layers (for in-situ concrete) or for the spacing of the interior surfaces of the form (for element walls) in order to ensure a technically correct installation of the concrete: „„for a largest particle of 8 mm bW,i ≥ 120 mm

Design and construction of components impermeable to water* Proof

Proof of impermeability to water is an additional proof of fitness for purpose for DIN 1045-1, Clause 5.4.1, Section 2. Limiting the crack width For bending cracks resulting from stress and forces it must be proved for utilisation class A, stress class 1, that the pressure zone height (x) satisfies the condition x ≥ 30 mm and ≥ 1.5 · Dmax, whereby Dmax is the largest diameter of the aggregate. If there is an acceptable temporary ingress of water through separating cracks for stress class 1, the calculated widths of the separating cracks in relationship to the pressure gradients are to be limited according to the table. Pressure gradient hw/hb*

permissible crack width w [mm] (calculated value)

10

0,20

> 10 bis ≤ 15

0,15

> 15 bis ≤ 25

0,10

Proof for utilisation class A The required proofs conform with the selected design fundamentals of utilisation class A. For this, verification is needed that no separating cracks occur in the concrete as a result of force. The exceptions here are the planned, sealed joints. To this can be counted the precrack dummy, construction and expansion joints through the arrangement of which, at specified spacings, the reduction in the force on the structural components follows.

Proof for utilisation class B The required proofs conform with the selected design fundamentals of utilisation class B. Their requirements are met through a limitation of the separating crack widths with the assumption that the cracks are self-healing. The limitation of the incident crack width results from the design of the pre-crack dummy and construction joints and/or the arrangement of the reinforcement.

The limitation of the incident crack widths results from the design of the pre-crack dummy and construction joints and/or the arrangement of the reinforcement.

* hw = pressure head of the water in m hb = component thickness in m

If the table values are adhered to, it can be assumed that the initial water ingress will be greatly reduced with time through self-healing of the cracks. Humidity spots on the surface of the structural component cannot, however, be ruled out with certainty even at a later time. For stress class 2, the permissible crack width for walls w ≤ 0.20 mm applies to the calculated value, for floor slabs proceed according to DIN 1045-1, Clause 11.2.1.

Example of utilisation class A Standard for housing and rooms with high quality use

Example of utilisation class B Single garages, underground parking and storage rooms with lower demands

Design and construction of components impermeable to water* Reinforcement and constructional regulations The configuration of the reinforcement in the structural components must be designed such that it is possible to have a faultless insertion and compaction of the fresh concrete. WU components of stress class 1 should be fabricated with a double-sided mat reinforcement composed of longitudinal and transverse reinforcement. The exception to this are prefabrications of stress class 2. The construction joints must be defined by the designer and represented in a blueprint. In accordance with the defined stress and utilisation class, all joints in WU construction components must be permanently guaranteed by a complete sealing system that is impermeable to water and uniform. Pre-crack dummy sections are caused by sufficient weakening of the concrete section (at least 1/3 of the structural component thickness) and must be sealed for the smallest, but nevertheless appreciable, movements. Special pre-crack dummy elements guarantee both requirements and are thus suitable for structures of utilisation class A. Element wall splices are to be designed as pre-crack dummy sections.

Joint sealing Only products holding a proof of applicability may be used for sealing joints in WU structural components. A general building authority approval (abP) provides this proof for non-standardised products. All of the joint seals that connect with the concrete must be precisely placed according to the design, connected to the splices and forcefully and permanently secured in position prior to the concreting operation.

Coated laminations A joint sealing system must constitute a closed system and have a sealed contact to all of the connection and crossing points. In the case of joint sealing for precrack dummy sections it must be ensured that the sealing effect is maintained in the event of crack formation and the associated widening of the joint. An integral joint laminate does not absorb any kind of shear force. The lamination must demonstrate sufficient elasticity to survive any possible deformation without damage. This will prevent any temporary seepage of water. For coated laminated joints, considerably less anchoring depth in the concrete is required, as is the case, for example, for uncoated joint laminations. The necessary minimum anchoring depth can be taken from the proof of fitness for purpose (abP).

Design and construction of components impermeable to water Extract from the practical instructions for the basic blueprint "Method of construction with reduced force loading": Construction system for floor slabs At least one layer of PE film must be laid on a sub-base underneath the floor slab. The minimum thickness of the floor slab is based on the WU guidelines. For pressurised water this is 250 mm. The concrete cover of the upper layer of reinforcement is the responsibility of the building contractor and must be precisely complied with. This is a prerequisite for the pressurisedwater- tight installation of the PENTAFLEX® joint system. From experience the minimum degree of reinforcement of the floor slab is at least approx. 0.15% of the concrete section on both sides. If the proof of stability provides for a higher reinforcement content, this must be installed. This minimum reinforcement is to be arranged crosswise in two layers. Re-entrant corners must be secured by a diagonal reinforcement (e.g. 3 pieces Ø 12 above and below). The required wall connection reinforcement, e.g. Ø  8 nails with predetermined spacing for prior anchorage. Otherwise compliance is required with the reinforcement guidelines of DIN 1045-1.

Concreting The grades of concrete in accordance with DIN 1045 II/EN206 must be adjusted to take account of the required exposure class and the special requirements of the building provisions. If the consistency for processing the concrete on the building site is finally discontinued, a water-reducing admixture (FM) must be used. At the same time it must be guaranteed that any concrete additives that have already been added are compatible with the water-reducing admixture (FM). The maximum amount of additive according to the manufacturer’s instructions must not be exceeded.

When concreting the floor slab, make sure that the concrete is introduced and compacted fresh on fresh. In the area of the PENTAFLEX® elements care is required when inserting the concrete. If the floor slab is thicker than 400 mm, the concrete must be inserted and compacted in two layers (fresh on fresh). To facilitate after- treatment, the concrete slab must always be covered with film and must be protected from strong solar radiation with water and from frost with heat protection mats.

Design and construction of components impermeable to water Extract from the practical instructions for the basic blueprint "Method of construction with reduced force loading": Provisions when concreting wall elements Due to the small cross section of the core concrete, special care is required when concreting the core of the element wall. Initially it is essential to check the filling area of the element walls for loose assembly elements, impurities and contamination of the joint elements. Where necessary these must be removed. The surfaces of the concrete form that face the core must be wetted before concreting. The corner and straight splices

of the wall elements must be secured against the concrete pressure using the specified formwork pressure retaining elements and supported with angled braces. The concrete is introduced in layers of maximum 800 mm and compacted in accordance with the formula: diameter of the vibratory concrete poker x 10 = efficiency. The vibratory concrete poker is inserted quickly and slowly with-

drawn again. The poker is inserted far enough so that the layers bond with one another (needling). The layers must be introduced fresh on fresh. Up to a height of at least 300 mm, a concrete mix should be used with a largest particle size not exceeding 8 mm. This ensures a zero defect attachment to the base of the wall. For windows and other recesses the concrete is filled on one side until it comes smoothly out on the other side.

The product

Features

Application area

The combination of seal and foundation earth – double security in one work step: a seal which resists pressurised water and also acts as a foundation earth. The product benefits of the triedand-tested PENTAFLEX KB® joint plate remain the same: water pressure tested up to 5.0 bar, approved up to a water pressure of 2.0 bar. In addition to sealing, the element also performs the function of a conventional foundation earth. Tests, occasionally up to the highest lightning current class (class H), have been successfully carried out at the high-voltage laboratory of the University of the German Federal Armed Forces in Munich. This means that the PENTAFLEX KB® Plus product can be used universally as a foundation earth.

„„Twice as reliable due to the combination of tried-and-tested PENTAFLEX® quality seal and foundation earth

The foundation earth is an integral part of the electrical services of the building. It is part of the equipotential bonding of the building services and, if necessary, an element of a lighting protection system. The foundation earth normally consists of a closed ring-shaped steel band. The steel band is embedded in the concrete of the foundation and the walls it supports. The PENTAFLEX KB® Plus product therefore has two functions: when installed as ring-shaped sheet steel element in the foundation, it acts as a seal and also as a foundation earth.

Technical information General

According to the current rules and standards, the foundation earth must be connected to the reinforcement every two metres. In addition to the envisaged connection with the reinforcement, it is also possible to connect commercially-available connecting lugs or fixed earthing terminals. The main earthing rail, lightning conductor or extension of the earthing system such as an exterior ring earth connection or

earth rod can then be connected at these points. This means that PENTAFLEX KB® Plus can be used universally. By connecting an equipotential bonding strip, the PENTAFLEX KB® Plus product can function as an equipotential bonding ring conductor as well as a foundation earth.

Electrotechnical information The following expert appraisal is the basis for use and installation of the PENTAFLEX KB® Plus product: Prof. Kern, Technical University of Aachen "Joint plates and fastenings manufactured by H-BAU Technik for foundation earthing of a building" dated 20.03.2013 This document was been prepared based on the result of a lightning current resistance test to DIN EN 50164-1 at the University of the German Federal Armed Forces in Munich. The PENTAFLEX KB® PLUS product satisfies the requirements for

lightning protection in accordance with DIN 18014: "Foundation earth General planning principles" September 2007 The foundation earth is prescribed for all new buildings according to the technical supply conditions of the network operator and the DIN 18015-1 planning standards. During installation make sure that the PENTAFLEX KB® Plus product is connected to the reinforcement at least every two metres using the PENTAFLEX® Plus connector.

If the footprint of the building is greater than 20 x 20 m, commercially-available earthing bands must also be connected to the PENTAFLEX KB® Plus product. The additional earthing bands must have a mesh-type form. The maximum enclosing surface of the individual meshes must not exceed 20 x 20 m. Commercially-available earthing products can in principle be connected via the PENTAFLEX® Plus connector. In this case it is essential that the clamps used are suitable for concrete steel with ds=8 mm.

This ring earth electrode must be installed outside the white tank. Commercially-available products can be used for this. The ring

earth electrode must be connected to the foundation earth using commercially-available products. The connection is established using commercially-available clamps via the PENTAFLEX® Plus connector. When establishing the connection between the ring earth

electrode and foundation earth, make sure that leak-tightness of the white tank can still be guaranteed. The connection must therefore be above the highest ground-water level or routed inside the building using watertight wall lead-throughs.

using the PENTAFLEX® Plus clamps. According to DIN 18014, expansion joints must be bridged using electrically-conductive expansion strips. These commercially-available expansion strips are normally connected to commercially-available fixed earthing terminals. An electrically-conductive connection is then established via

the PENTAFLEX® Plus connector between the fixed earthing terminals and the PENTAFLEX® Plus clamps. The clamps and connectors must be assembled in accordance with the installation instructions. A schematic representation of the bridging of an expansion joint is shown below:

Expansion joint construction Expansion joints must be bridged by water-impermeable electrically-conductive means. These joints are sealed using the tried-andtested PENTAFLEX® DFA expansion joint connector. The expansion joint connector is connected to the PENTAFLEX KB® Plus base element.

PENTAFLEX® Thermo-Transwand Technical information

Materials PENTAFLEX® Transwand General In recent years, double element walls have been systematically developed. Nowadays, double walls with internal thermal insulation are no longer the exception. These thermal walls are being used both in residential and industrial buildings. Two points must be clarified when using PENTAFLEX® pipe lead-throughs in thermal walls: „„Are they to be installed in water-impermeable structural elements such as thermal walls for cellars or „„Are they to be installed in thermal walls for multi-storey buildings or halls that do not have to comply with the WU guidelines?

„„The thicknesses of the formwork PENTAFLEX® pipe lead-throughs are designed for water-impermeable structural components. According to the WU guidelines, a minimum core concrete thickness of 120 mm applies with a maximum grain size of 8 mm for element walls of stress class 1. This ensures that the seal on the inside will be of sufficient quality.

PENTAFLEX速 Glossary*

Attachment mixture: comprises a concrete with a maximum aggregate particle size of 8 mm that can if required be used at the attachment area between walls and floor slabs or ceilings. Stress class: defines the type of stress due to moisture or water a structure or structural component can withstand. Soil humidity: amount of capillary-bound water in the soil. Pressurised water: water that applies hydrostatic pressure (also time-limited, e.g. retained seepage water) on one side of a structural component. A differentiation is made in the following case: Occasional retention of seepage water: water that flows off freely under the influence of gravity and can accumulate from time to time on soil layers with low permeability. This type of stress occurs when the embedment depth of the structure is less than 3 m in soil of low permeability without drainage in accordance with DIN 4095, when the base of the structure is at least 300 mm above the design flood level and only backwater is anticipated due to the type of soil and terrain. Ground water, high water, strata water: any kind of pressurised water that are not temporarily retained seepage water. Penetration: occurs when a structural component penetrates a water-impermeable structure, e.g. pipes, discharge, cable lead-through, formwork ties or similar. Element wall: structural wall elements comprising two interconnected prefabricated slabs supplemented by a core of in-situ concrete. Pre-fabricated element wall: wall constructed from single-skin prefabricated wall elements. Joint: interface between two structural components or concreted sections. A differentiation is made in the following case: Construction joint: interface which is in direct contact with two bonded concreted sections. Construction joints without joint sealing are regarded as separating cracks. Expansion joint: intermediate space between two structural components or concreted sections that permits different types of deformation. Butt joint: joint between two hardened concrete structural components with negligible relative deformation of the adjacent components (in-situ concrete/prefabricated component; prefabricated component/prefabricated component).

60

www.h-bau.com

Joint seal: built-in components and building materials for sealing a joint or shinkage crack control section to prevent the ingress of water. Non-pressurised water: water in fluid droplet form that applies no, or negligible, hydrostatic pressure (100 mm water column) to components. Non-retained seepage water: water that seeps into the soil and can seep through to the free ground water level in the case of highly permeable soil without being retained or, in the case of less permeable soil, can be drained off in front of the structural component by a permanently functional drain in accordance with DIN 4095. Utilisation class: defines the requirements for the internal environment and humidity conditions for the surface of the components based on the planned use of the structure or structural component. Crack: break in the concrete structure. A differentiation is made in the following case: Bending crack: crack with greater depth which does not run through the entire thickness of the component and separates the component thickness into a cracked (tensile zone) and uncracked area (pressure zone). Separating crack: a crack which runs through the entire thickness of the component. "Self-healing" of cracks: time-based reduction of water ingress by separating cracks depending on the crack width and fluid pressure gradient. Shrinkage crack control section ("dummy joint"): weakness that is designed into the component cross-section, also of the reinforcement crossing at this cross-section, in order to bring about a break in a specific location. Shrinkage crack control sections without joint sealing are considered as separating cracks. Water passage: transport of moisture in liquid form through the component to the surface. Water impermeability: qualitative or quantitative statement on extent to which water can pass through concrete, joints, built-in components and cracks. Force: stress that occurs as a result of preventing load-independent deformation, e.g. due to the effects of changes in temperature or shrinkage.
