Earth Retention & Shoring is used to contain soil that is exposed to either a natural, uneven slope or a constructed excavation and to support existing adjacent structures.
- Support excavations and existing adjacent structures
- Stabilise slopes
Earth retention and shoring systems are designed around some of the most complex issues cause by soil structure, depth of cut, ground water, weather conditions, loads, vibrations, and adjacent construction. When below the water table, they address excavation bottom stability.
Adjacent structures, construction equipment, and stockpiled materials result in lateral loads on the retention system, underpinning these can reduce the loading on the excavation wall and decrease the danger of building settlement. Vibrations from traffic, railways, blasting, and machines operated in adjacent buildings can affect excavation shoring.
Typical permanent and temporary earth retention and shoring systems include sheet piling, solider piles and lagging, chemical or jet grouting, secant or tangent piles, and soil nail walls.
Sheeting and shoring systems use anchors or bracing for lateral support. A circular shoring system designed as a compression ring can be used for access shafts for tunnelling and trenchless construction. Some excavations that are open for a prolonged period may need protection from various weather conditions. Safety is our highest priority during shoring excavation and extreme caution is taken. We have extensive knowledge of the hazards involved with this type of work. We have the full range of techniques and experience to be able to provide our clients with reliable earth retention and shoring systems.
