For this reason, quite a few specifications as well as the "PCI recommended techniques" recommend using a whole new cushion Firstly of driving of every pile. In comparison towards the cost of the pile They can be provided to safeguard, the cost of the cushion Micropile design specifications is frequently very small and it really is usually Wrong financial state to test to utilize a cushion over and above its helpful existence. The achievable damage to the pile, cost of a re-push or unscheduled downtime switching a cushion with a partially pushed pile are all explanations for being mindful with the condition from the cushions when driving concrete piles.
