Repair to retaining wall using the Heli Pile
The horizontal mortar joints were cut out 10mm wide and 65mm deep, using a mortar raking machine fitted with a dust extraction system, at 450mm centres over the height of the wall.
Two 6mm continuous stainless steel helical bars were inserted into the pre-cut joints with cementous non-shrink pump able grout.
At the points where the stud from the pile protruded, 6mm stainless steel helical bar were placed either side. A large stainless steel washer and nut clamped the helical bar to the pile and the connection was pressure grouted on completion of the installation.
