Getting the site right is one thing, but you’ll need the right geotechnical numbers too.
Building from the ground up
Our ethos is the cross-pollination of science and engineering. Our team undertakes geotechnical site assessments for projects of all sizes to obtain a detailed understanding of the site’s surface and subsurface variability. With LDE, you have ground engineering you can rely on and is backed by Chartered Professional Engineers specialising in geotechnical engineering.
Foundations are our forte
We’ll work out the best solution for your project and its underlying ground conditions and constraints, from shallow raft foundations to deep, laterally loaded piles.
Practical geotechnical solutions
Providing practical solutions is one of our core principles. Your site might be plagued with geotechnical issues, but we’ll find a way to make it work at the lowest possible cost. Our geotechnical engineering team have the skills and technical expertise to get the best outcomes and minimise risk.
Our expertise includes:
- Geotechnical investigations
- Optimum site location
- Landslides and slip assessment, stabilisation, and mitigation
- Liquefaction assessment and minimisation
- Lateral spreading assessment and deformation mitigation
- Understanding your ground settlement risk
- Preload fill design to minimise settlement
- Designing and certifying your earthworks
- Geotechnical parameter analysis
- Bearing capacity reports
- Shallow foundations
- Deep pile foundations
- TC2 and TC3 foundation design
- Tsunami resilient foundation and building design
- Cut and fill slope gradient design
- Slope retention and retaining walls
- Palisade wall/soldier pile wall design
- Ground improvement design
- Stone columns, rammed aggregate piers, cement columns
- Lime stabilisation
Project Experience
Location: Mahia Beach, Mahia Peninsula
Client: Wairoa District Council
The sewerage ponds were surrounded by unstable hillsides, while underneath was soft, compressible ground. This site required creative solutions. We carried out a comprehensive geotechnical investigation for the ponds, making appropriate recommendations for the site.
