A deep foundation system creates support of building loads utilizing piers or piles to reach a deeper, more stable subsurface layer.
A strong and versatile solution for deep foundation systems, Helical Piles can be used to support wall loads and/or pile caps supporting massive loads. Installed by hand, or with any variety of construction equipment, helical piles are ideal for projects of all shapes and sizes. Advanced into the ground to appropriate depths for stable soils or bedrock, the piles then brace against foundation footings and transfer weight carefully from subpar soils down to competent strata – completely stabilizing any foundation.
Micropiles are small diameter drilled and grouted friction piles. Each pile includes steel elements that are bonded into the bearing soil or rock – usually with cement grout. Since micropiles are bonded to the rock socket wall, they do not rely on end-bearing capacity and there is no need to establish competency of rock beyond bond-depth. They can be installed quickly in virtually every type of ground using highly adaptable mobile drilling equipment.
Ideal for stabilizing and/or lifting sinking or settling foundations, Push Piers use high-strength steel tubes and load transfer brackets to transfer structure weight to solid, load-bearing soils or bedrock. Piers are hydraulically driven down to competent strata until the target load/pressure is achieved or the structure begins to lift.
Grouted helical pull down piles can be advanced with smaller equipment in limited access areas. Installation is vibration-free and does not generate spoils. The grout column surrounds the pile shaft to create a pile that is more resistant to buckling. Where favorable soil conditions exist, a grouted helical pull down pile may achieve allowable capacities exceeding 100 kips, which may then be considered as an economical alternative to large diameter helical shaft sizes or other deep foundation options.
