Geotechnical & Materials
Our geotechnical team investigates the ground, designs foundations to suit it, and improves it where needed. We bring the same professional approach to large multi-disciplinary investigations and to small, simple structures, supported by our own testing laboratory.
Investigations
Every foundation decision rests on knowing the ground. We plan and carry out investigations, from boreholes and SPT to plate and pile load tests, and interpret the results for design.
- Planning and design of ground investigations
- Borehole drilling and SPT
- Rock coring and sample analysis
- Trial pits and in-situ testing
- Plate load and pile load tests to IS and DIN
- Electrical resistivity tests
- Groundwater monitoring, sampling and analysis
Foundations & Ground Improvement
Where the ground is weak or the loads are heavy, we design foundations to suit and improve the soil where needed. Slopes, deep excavations and existing structures are stabilised with proven techniques.
- Design of deep foundations (piles, wells) and mat foundations
- Slope stability analysis
- Sand piling for poor sub-soil
- Underpinning of existing structures
- Soil nailing and shotcreting
- Bored cast-in-situ piles and micro piles
Materials Testing Laboratory
Our laboratory tests soils, rock, aggregates and concrete to the relevant standards. Results feed directly into design and into quality control during construction.
- Particle size analysis and Atterberg limits
- Swell index, swell pressure and swell potential
- CBR, soaked and unsoaked
- Direct shear and water content
- Uniaxial compressive strength, specific gravity and water absorption of rock
- Concrete cube compression and aggregate tests
