Bored Piles within 50mm of a Boundary Wall
 We offer concrete piling using ABI’s double rotary head auger system that enables us to pile within 50 mm of a boundary wall.
Advantages:
- The pile wall is 50mm from boundary wall
- Provides an additional 1 linear meter of space around the edge of a basement car park
- Eliminates spreading in Secant wall
This is achieved through the use of a specialist attachment known as a ‘Cased Dual Rotary’ head. The system is known as VDW (Vor Der Wand = in front of wall).
It allows the steel casing to pile in line with the hydraulic motor thereby no loss of space exists between the pile and the boundary wall.
This technology facilitates a high quality finish on pile walls, as the steel casing leaves a clean, smooth pile and ensures that when driving secant piles, maximum efficiency is achieved as the finished pile is more accurate in its vertical direction and distance from adjacent piles.
