Touch piles is a temporary or permanent retaining wall commonly used for excavations in urban areas.
Touch piles are most suitable in conditions where well constructed walls will not result in subsidence such as over-consolidated clays, soils above the water table if they have some cohesion, and free draining soils which can be effectively dewatered, like sands.
They consist of multiples piles spaced apart from each other to support a change of elevation.
Touch pile Shoring is very versatile because the size of the piles and the spacing between them can be adjusted to site soil conditions.
