Chemical grouts and cementitious grouts are used below grade for soil enhancement, for repairs such as building, bulkheads, and open cuts pits/tanks. Soils can be modified to increase compaction, tensile and shear strength. The injection of grouts to stabilize soil formations is very useful in projects around waterways where forming and pouring concrete is not possible. Grouts vary in performance from rigid, gel or elastomeric to allow for adhesion and cohesion capabilities. Traditional applications are commonly used in open cuts for tanks, collection pits, building and bulkheads.
Soil nails are steel rod or cable grouted in boreholes, anchoring potential slide masses. Short soil nails may also be used to anchor shotcrete or reinforced gunite walls.
For below grade structural repair in or around buildings, bulkheads, pits or tanks.
Grouts can increase compaction, tensile and shear strength. Injection of rigid, gel or elastomeric grouts with adhesive and cohesive properties can allow excavation after soil stabilization.
