The Collin Group (TCG) has extensive experience with the design, specification development, construction of earth retaining system for over four decades. This includes:

TEMPORARY EXCAVATION SUPPORT

  • Soldier beam and lagging walls
  • Tangent pile walls
  • Slurry walls
  • Soil nail Walls

Soil Nail
Soldier Beam Concrete Lagging

EMBANKMENT OVER SOFT SOILS

  • With geosynthetic reinforcement
  • Without geosynthetic reinforcement

REINFORCED SOIL SLOPES

MECHANICALLY STABILIZED WALLS (MSE)

MSE Wall
Welded Wire Wall

The design of these structures by TCG has utilized state-of-the-practice design tools for typical projects. However, for complicated projects where more rigorous analysis is required, state-of-art tools like Plaxis and FLAC 3D are used to better understand the soil-structure interaction.
