At some point we decided to jet the pile so far as it would go after which you can driving it (pneumatic hammer) to suggestion elevation or refusal (whichever arrived 1st). Since the fabric was in Micro pile construction methods actual fact jetted, it built the driving simpler and we obtained tip elevation more often than not.
