GH Form markets the Aquaform® range of rainwater diversion and drainage products.
Via an EU Regional Development Fund project, “Investing in our shared future”, Provice (Danish process consultants) analysed GH Form’s products.
“In our analysis, we compared GH Form products and products from a European competitor to quantify the impact of using 100 % recycled iron produced at the Ferrofoss foundry (owned by GH Form). We conclude that using 100 % reclaimed iron is indeed significant to the foundry’s total environmental impact. The production of one GH Form linear drainage grate emits 3.58 kg CO2, whereas the carbon footprint of a comparable product produced by a European competitor is 14.59 kg CO2”
A comparable European competitor uses 35 % reclaimed iron and 65 % iron ore and has also higher transport costs. The calculations were made in the SimaPro LCA calculation tool. Our carbon footprint is calculated in a cradle-to- grave perspective. It is based on one GH Form Aquaform® linear drainage grate weighing 5.5 kg compared to a corresponding European competitor product.
GH Form and the UN Global Environment Goals
We strive to comply with the UN Global Environment Goals. We focus on certain goals: 7, 8, 11 and 12:
No. 7
Affordable and Clean Energy
The most sustainable energy is energy that we don’t use. We strive consistently to minimise our energy consumption by investing in energy-efficient technology and optimising the amount of energy we use for heating and melting iron.
No. 8 Decent Work and Economic Growth
We are proud to say that we are a great place to work. We respect our employees and believe it is important to meet their needs. We create economic growth via good design and sustainable production.
No. 11
Sustainable Cities and Communities
Via sustainable production processes, we make a positive contribution to tomorrow’s urban spaces. Good design is only sustainable if it is appreciated. By diverting rainwater into stylish and attractive linear drainage grates, Aquaform® helps making society sustainable.
No. 12
Responsible Consumption and Production
Aquaform® maintains an especially sustainable consumption of materials. We use only recycled materials from other production sites on Zealand (a Danish island). We deploy the most eco-friendly method of melting steel when we make cast iron in electric ovens.
About Aquaform® Linear drainage with concealed frames
Linear drainage
All standard Aquaform® grates were originally developed to order for projects and designed in collaboration with Danish and Swedish architects for:
Købmagergade, Copenhagen

Campus linear drainage
Campus linear drainage and paving slab are made of SG iron and suitable for heavy duty use (heavy vehicles).
A stainless steel spring lock locks the linear drainage grate or paving slab to the channel. The spring lock is not visible when the grate/ paving slab is in place on the channel. The grate and paving slab are designed to conceal the edges of the water channel beneath. The top course can be laid right up to the grate/paving slab. When laying in asphalt, a stainless steel profile can be attached to one or both sides of the polymer concrete channel.
GH Form produces Campus linear drainage elements to order with a customised radius, i.e. so that the grate/paving slab are seated tight in the longitudinal direction.
At entrances and other transitions, it is often an advantage to combine the band of Campus linear drainage grates with Campus paving slabs.

Klima linear drainage system, 90 tons
The Klima linear drainage grate and coordinating cast iron channel are made of SG iron and suitable for very heavy duty use (heavy vehicles).
The grate must be level with the top of the cast iron channel, i.e. so that you can lay asphalt right up to the top edge. You can level the asphalt without deforming the channel. The upper side of the grate has an anti-slip relief pattern.
The combination of the sturdy dimensions of the grate with the optimised, profiled design of the channel makes the system a very useful and well-thought-out product.
The channel can be seated without a moulded concrete encasement and still withstand 90 tons pressure from all sides. Danish Technical Institute has tested this product in accordance with DS/EN 1433:2002, clause 7.15.
GH Form has designed Klima linear drainage grate in cooperation with SLA Arkitekter (architects) and Danish Technological Institute.

Special projects
Designs to order
We can design a linear drainage system to order. You may require a design for use in a unique environment, e.g. specially designed to reflect the topography or animal life in or history of the site, or to make a creative design expression.
The linear drainage grate must be 500 mm long and may be 140, 190 or 240 mm wide.
Examples of customised designs and features:
· Radius
· Pattern
· Fountain
· Water mist
· Lighting Radius
GH Form can produce a linear drainage system radius to order. The design ensures that the grates flush lengthways along a curved linear drainage band.
Pattern
GH Form can produce a grate with a customised pattern. We can also produce cast iron paving slabs or tiles with the same pattern and formats as grates.
Fountain and water mist
GH Form can supply grates with nozzles for a fountain and/or water mist system.
We can produce a linear drainage system where the fountain gradually increases in response e.g. to the sound of a passing bus, to shift focus away from the noisy bus and enhance the energising sound of the water in the fountain.
Lighting
GH Form can also fit light sources to grates so that they function as path lighting at night. At best, illuminated grates add visual impact to streets, avenues and squares.
GH Form develops customised grates, paving slabs and tiles in collaboration with Aquaform®. The latter is responsible for labelling the grate/ paving element(s) to coordinate with the channel.

Polymer concrete water channels
Straight channels
Aquaform® provides polymer concrete water channels in the following widths: 140, 190, 240, 400 and 500 mm.
The channels are seated 30-35 mm from the top of the top course (measured from the profile). The precise measurement depends on the choice of grate. The channel is then seated 4 mm under the level of the top course. When using stainless steel profiles in connection with laying asphalt, the channel must be seated 2 mm below the level of the top course.
Water channels, width 140 mm
The water channels are made of polymer concrete. Standard usage: GH 10.15.0 with dimensions:
Outside width: 140 mm
Outside length: 1000 mm or 500 mm
External fitting height: 255 mm
The standard channel is available with vertical, horizontal or end cap outlet. To construct pre-sloped channels, see channel overview on page 15.
Sealed joints
If sealed joints are required, e.g. in decks between floors or special environments, use the sealing grooves at channel element ends. Sealing is simple: Use a sealant gun and seal the elements as you work. NB: Use a suitable adhesive or sealant product. When this work is complete, the sealant is concealed and protected from mechanical overload.

Corner and T-joints
GH channel 500 mm, straight, is used to create T-joints.
At corner joints, cut the grate and channels to the desired measurements on site. GH Form is at hand to guide and assist you. We also cut grates and channels to order.
Examples of corner joints shown in the image below.
Channel overview, 140 mm, pre-sloped, and accessories
Height = height of channel with frame but without grate. Grates measure 4-10 mm in height when fitted in the channel. The total installation height is therefore channel height + 4-10 mm (depending on choice of grate).

End caps are available in two versions: With and without outlet. End cap with outlet is an end cap + a gasket. End cap without outlet is a closed end cap.
Use a GH.10.10.LP end cap with our shallow profile channel, GH.10.LP Aquaform low-profile channel. This is a closed end cap.
A connector is inserted between channel and drain. At a vertical drain that runs directly from the channel, tap out the recess in the base of the element from the inside. Insert the drain connector in the outlet hole before positioning the channel. If the channel has a vertical outlet, it also has a sealing groove for adhesive and sealant.

Water channel frames
We offer a range of frames:
· Plastic frame for use with tiles and paving stones
· Stainless steel frame for use with asphalt
· Cast iron frame to reinforce channel top*
*Also suitable for use with asphalt
The steel frame is suitable for use with asphalt. It is made of stainless steel and has an additional flange that extends up around the grate, so asphalt can be laid right up to the frame edge. The grate is therefore loose and can be removed without damaging the asphalt. See fig. 02.
It is possible to fit a plastic frame to one side of the channel and a steel frame to the other, if asphalt will be laid only on one side of the grate.
A cast iron frame can be used if there is a need for additional reinforcement at the top of the channel. The frame has transverse supports — across the channel — for especially robust reinforcement. The cast iron frame can also be used with asphalt top course. Available in widths 140 mm and 240 mm.

Laying instructions
How to lay polymer concrete channels and grates
Aquaform® recommends that the finished channel with grate lies 3-4 mm under the level of the adjoining surface to ensure that surface water flows freely into the grate. Seat the channel elements a further 6 mm under the level of the adjoining surface to compensate for the lock-down mechanism on the grate.
Seat the top edge of the drainage channel 30 mm lower than the adjoining surface. See fig. 04.
Aquaform® channel elements are designed to transfer traffic forces to the concrete encasement. See fig. 06.
GH Form drain channels are cast in concrete to meet load class (fig. 03). See overview in section. How to determine load class
Seat and adjust the elements on a concrete bed. Always begin at the outlet. Slide each element vertically into the groove in the previous element. Before laying, saw off any superfluous grooves on the two elements using an angle grinder. When the channels are laid and adjusted, encase on both sides.
Ensure that the grates or planks are in place (22 x 128 mm, fig. 05) during moulding and laying. General recommendation: Always use planks – especially when laying tiles and rubber surfaces. During levelling, planks protect the grate profiles from horizontal forces that can cause grates to jam. Planks also save you much subsequent cleaning of grates and channels. NB: Seat the top edge of the drainage channel 30 mm lower than the adjoining surface. For long-lasting, professional results, use suitable materials, optimal drain design and, last but not least, lay carefully.
When laying tiles and paving stones right up to the channel, it is important that there is no sand against the channel. This is firstly because sand does not transfer traffic load forces applied to the channel walls and secondly because vertical forces on paving laid in sand discharge horizontal forces on the channel wall that can cause overload. See fig. 07.
Practical advice
NB: Always lay the channel and then mould an encasement around it in accordance with load class before laying the adjoining surface.
If you lay paving stones right up to the channel, always set one row of stones against the channel in the concrete encasement. Never lay more than 30 mm asphalt right up against the channel. Lay sufficient asphalt to compensate for levelling and subsequent rutting (due to heavy traffic). When laying a large area of concrete, configure expansion joints: parallel with and 1.5–2.0 metres from the channel, and at right angles to the channel opposite a channel joint (maximum 8 meters between expansion joints).

Open linear drainage
V-channel
The V-channel is a surfacing element that can withstand particularly heavy vehicle traffic when it rests on a strong bed of concrete.
The channel can be used in open linear drainage applications along roads, plazas and other surfaced areas.
The V-channel has a slightly V-shaped profile that meets accessibility requirements. The transverse slot pattern is anti-slip. The V-profile is clearly visible from above.
The channel is designed for seating in soil concrete. It is easy to seat. The open ends have integral tongue and groove connections.
The V-channel is developed by BOGL Arkitekter (architects) in collaboration with GH Form.
Dock-Line open linear drainage
Dock-Line open linear drainage is a paving element made of cast iron with striking lengthways slats. The elements are designed to be seated in soil cement.
The open ends of the element have tongue and groove connections which guide the position of elements during laying. This linear drainage system can withstand heavy-duty traffic as it rests on a strong concrete bed. The elements are easy to seat.
For tile-laying projects, the grate is supplied with a thin, watery surface treatment.
