Though the piles are founded at some depth below the slopes, lateral load arising from wind on buildings may induce loads on the slop and causes slope failures. ... Hence, an annulus of compressible material called sleeving is introduced in piles so as to reduce the transfer of lateral loads from buildings to slopes.

What is pile sleeving?

Pile sleeving is an annulus of compressible material between a laterally loaded pile and the adjacent ground and is a method adopted in Hong Kong for protecting the stability of sloping grounds and retaining walls.

What is the purpose of piles?

The primary function of a pile foundation is (a) to transmit the load of a structure through a material or stratum of poor bearing capacity to one of adequate bearing ca- pacity; (b) in some instances, to improve the load-bearing capacity of the soil; and (c) to resist lateral loads and to function as a fender to ...
