Firstly, there was a L shaped permanent retaining wall we had to install so our client could weld some angle to the sheet piles. This allowed them to build a brick wall to 'cloak' the piles...allowing them to excavate to build footings for new houses on a development.
As the ground conditions were stiff clay, the pile line was pre augered then the piles installed with our SG75 Movax and impact driven to level with our new DH20 Impact Hammer . The Impact Hammer is attached by the quickhitch of the excavator. This saved the client time and money as otherwise they would have had to provide a suitable platform for a mobile crane to impact drive the piles with a conventional Impact Hammer.
