The safety of a foundation, particularly in low resistance soils, depends largely to what extent the foundation can be tested.
Testing of GEWI® Piles in compression can be facilitated by using adjacent piles as reaction piles. Testing in tension is usually sufficient since the compression capacity of the pile is always slightly higher than the tension capacity.
Settlement or creep of GEWI® Piles under service loads is generally very low - usually less than 5mm. In granular soils, settlements of less than 2mm are common.
