Geotechnical Contracting and Engineering

Our Expertise

• Slope stabilisation

  Soil slope stabilisation involves actively stabilising ground or improving drainage in order to reduce the risk of instability. Our services in this area include soil nailing, installing slope netting, erosion matting and geocell facing systems, river and coastal scour protection and managing vegetation.

• Rock face stabilisation

  Rock face stabilisation removes or reduces the risk of rockfall. We specialise in scaling and re-profiling to remove loose rock, installing both passive and active rock netting systems, building dentition to support undercut rock masses, installing rock bolts and rock anchors to support large rock masses, and installation of sprayed concrete facings.

• Rock containment systems

  Where site conditions dictate that stabilisation to remove the risk of rockfall is not possible or cost-effective, we can install rock catch fences. These comprise high-capacity anchored fences that catch loose rock, dissipates the energy and prevents the rockfall from causing damage. We are experienced in installing some of the largest catch fences in Europe.

• Drilling and grouting

  Small-diameter piles are used to reinforced ground and provide support to structures or foundations. We can install mini piles, micro piles and bored piles up to 450 mm in diameter. We carry out bulk and injection grouting to fill underground voids or voids within structures. We are also able to carry out probe drilling to locate voids or investigate certain ground conditions.

• Structural reinforcement

  There are various methods of strengthening and repairing existing walls and structures to prolong their lifespan and to provide reinforcement for new-build structures. We install structural anchors and tie bars, carry out injection grouting, undertake repointing and can strengthen brick and/or masonry walls.

• Retaining walls

  Where there is a requirement to support a vertical or near-vertical face, retaining walls are often built to provide reinforcement. We specialise in building cast in-situ and pre-cast concrete retaining walls, reinforced earth walls, piled retaining walls and gabions. Tie back anchors or tie bars are also used to provide additional capacity.

• Sprayed concrete

  Sprayed concrete can be used to construct retaining walls, provide hard facing to prevent weathering of rock faces, construct head blocks and beams, provide dentition support for loose rock masses and to build on slope drainage channels. We undertake wet and dry sprayed concrete, including installing reinforcement and back of wall drainage.

• Drainage

  Drainage measures can help to reduce water levels within soil slopes and the risk of slope failure. We are experienced in installing incline drains, on-slope drainage systems, concrete-lined channels and interceptor drains.

• Geotechnical inspection and design

  Tactile inspections are used to investigate the condition of slopes and rock faces and provide recommendations to control any risks of instability. With our expertise in rope-access techniques, we can conduct up-close inspection and provide detailed reports. Through the wider group, we are also able to design remedial measures to solve the full range of geotechnical problems.
