The bearing stratum is logged in the course of installation drilling to make sure that bearing functionality is satisfactory.
Alternative piles are produced in just a previously drilled borehole, Consequently restoring the excavated floor.
Keller has huge load test experience in several rock formations and the chance to design and style in-house based on a variety of subsurface circumstances.
To transfer structural load to some capable bearing strata, micropiles, generally generally known as minipiles, needle piles, or pin piles, are utilized in almost any sort of ground.
