Ground Conditions & Engineering Solutions
From liquefaction-prone soils and soft ground to steep slopes and complex geological conditions, we provide specialist geotechnical assessments and practical engineering solutions tailored to each site's unique challenges.
TC1, TC2 and TC3 - Liquefaction & Seismic Hazards
Assessment of liquefaction potential, earthquake-induced settlement and lateral spreading risks.
Liquefaction & Earthquake-Induced Settlement
Specialist liquefaction assessments using Cone Penetration Testing (CPT) and site-specific geotechnical analysis. We evaluate liquefaction potential, earthquake-induced ground settlement and lateral spreading risks to develop appropriate foundation designs, ground improvement solutions and remedial engineering strategies.
Soft Ground & Compressible Soils
Specialist geotechnical investigations to assess weak and compressible soils, bearing capacity and potential ground settlement. We provide practical foundation solutions, including reinforced gravel rafts, ground improvement and piled foundations, tailored to site-specific conditions and structural requirements.
Hillside Developments & Slope Stability
Specialist geotechnical and structural engineering for hillside developments and challenging terrain. Our expertise includes slope stability assessments, landslide risk evaluation, retaining wall design, rock anchors, shotcrete wall and ground stabilisation solutions to support safe and practical development.
Mass movement sites
Specialist geotechnical and structural engineering for sites affected by potential ground movement, including slope instability, lateral ground displacement and differential settlement. We provide integrated ground assessments, foundation design and remedial engineering solutions to manage ground deformation and maintain structural performance.
Residential Ground Investigations & Foundation Design
Practical and cost-effective geotechnical investigations for residential developments, new dwellings and extensions. Our services include hand auger drilling, Scala penetrometer testing, soil classification and bearing capacity assessments, providing reliable ground information and foundation design recommendations tailored to each site.
