Excavation Support Services

Steel sheets are inserted into a sequence along a planned excavation perimeter, interlocking to form an enduring or temporary wall. The design offers lateral soil support and lowered groundwater inflow. The sheets are installed using vibration-free and vibratory installation rigs.

Steel sheet piling serves as a barrier to groundwater flow and is used when building cofferdams, seawalls, and bulkheads. The piles also support excavations in basements, pump houses and foundations.

This excavation support method uses vertical piles driven or drilled into the ground, then grouted. The vertical beams are placed at intervals along the excavation walls.

Soldier pile walls are embedded retaining walls. The soil is kept in place so the ground level in front of the wall can be lowered. These columns are used to secure slopes and excavations and retain cohesive soils.

This method combines soil with injected cement on-site to construct a durable column. The cement-soil beams can improve strength and lower permeability.

The overlapping columns form structural walls and provide the required water tightness. You can reinforce them with steel and anchors. Secant piles support wing walls, slope security and water cutoff for drainage channels and excavations

Tangent piles are a type of secant piles. The columns are created adjacent to each other along the boundary of the excavation wall, forming a structural or cutoff barrier. Tangent piles may be reinforced with beams and anchors.

Soil nailing uses grouted nails or tension-resisting steel elements to support the earth on-site. The technique uses a gravity retaining wall for temporary or lasting reinforcement.
