Derbyshire Geotechnical Ltd
Derbyshire Geotechnical Ltd is an established geotechnical installation service provider within the rope Access Industry
From its base in the Derbyshire Peak District, Derbyshire Geotechnical’s Ltd’s teams of Certified and experienced IRATA Operatives undertake a broad range of specialised Rope Access Geotechnical services installing stabilisation infrastructures in hard to reach/working at height situations.
Using fully qualified and experienced IRATA Rope Access Technicians the work includes de-vegetation, large/difficult tree removal, the installation of rock anchors, soil nails etc and installation of rockfall mesh, erosion matting and catch fences.
Still considered a relatively young company, Derbyshire Geotechnical Ltd was established in 2017 and has in this short period of time built a good reputation as a safe, reliable Geotechnical Rope Access operator that delivers quality installations at a very competitive price.
This wealth of experience in the industry has enabled the company to design and build projects like the ones listed below.
Rockfall Containment
Rockfall containment can involve the installation of a strong fence or barrier (Catch Fence) that is placed on a slope or beneath a rockface to catch debris, and protect structures, plants and persons beneath. Derbyshire Geotechnical Ltd also offer Catch Fence Inspection and maintenance services where these structures are already installed.
Slope Stabilisation
An installation that provides long term stabilisation for over-steepened or unstable soil slopes. The strength of the soil/ slope is increased by drilling and grouting hollow bar anchors in a regular pattern. This is installed in conjunction with a geotextile erosion matting or a combined rockfall mesh and geotextile layer which is secured to the slope by the anchors.
Rock Face Stabilisation
Rock Face Stabilisation involves the securing of unstable rock faces in three ways.
1. De-scaling – removing loose materials such as rock and overburden by hand, and for large blocks with airbags, to leave sound rock that requires little further intervention apart for regular inspection.
2. Installation of Rock Anchors and Dowels – Anchor holes are drilled using either a hand operated pneumatic drill or more frequently a rock drill mounted on a drilling frame or 360 excavator. Strong Steel Anchor Bars (Usually a Galvanised High Yield Steel Gewi Bar) is then inserted into the anchor holes and affixed into place with either a resin or cement grout, and they can hold both rock mesh and sections of rock face into place.
3. Installation of Rockfall Mesh – Held into place by the rock anchors and cables.
Facing Systems
Facing systems encourage vegetation growth and enhances the stability of the soil slope through soil retention. This is done through the use of a variety of anti-erosion and soil retention geo mats, but can alternatively be done with semi rigid geocell baskets or reno mattresses installed on steeper slopes or where high erosion rates can be anticipated. These facings may be tied back with soil nails or driven earth anchors.
De-Vegetation
De-vegetation involves the removal of weeds and dangerous or obstructive vegetation from either a structure, slopes or rock faces. This can be done as a way to assist inspection, remove potential hazards or as preparation for further works. Then the cleared area may be treated with an herbicide in order to restrict or reduce regrowth.
Structural Repairs
Although not typically a core area of work for the company, Derbyshire Geotechnical Ltd is able to offer structural repair services such as re-pointing, brickwork and concrete repairs.
Over the years Derbyshire Geotechnical Ltd has developed business relationships with clients such as; AMCO Giffen, Aggregate Industries, Bam Nuttall, Breedon Aggregates, Hanson UK, Keller Geotechnique, National Trust, TARMAC, and numerous local authorities.
Aside from the companies regular quarry work in 2021, we were privileged be able to work on location in Stoney Middleton, Derbyshire for the new Mission Impossible 7 film set; stabilising rock faces, installing special effect, working at height safety cover, assisting and aiding the production team in filming a spectacular scene from the film.
The company endeavours to stay true to its mission to provide a safe, reliable, professional, and excellent value for money service to all their clients in the UK and beyond, whilst striving for continual improvement.
