The rigid insulation and batt insulation must be thought of “sacrificial” and should be disposed of and replaced if wetted by floodwaters.
WEAP predictions ought to be compared versus genuine driving circumstances to validate their usefulness in pile capacity prediction. The usage of wave equation Evaluation is a robust Device to support driven pile installation projects and when included with higher pressure dynamic tests using a Pile Driving Analyzer (PDA) to validate hammer efficiency may lead to extremely successful pile installation assignments.
