Pier Liners

Pier liners are similar to column formers in that they contain poured concrete and reinforcing steel while curing but also prevent the excavated hole from collapsing prior to or during the concrete pouring process. Pier liners are usually constructed from a stronger galvabond material and are corrugated giving them additional strength to withstand ground collapse or can be offered in spiral welded mild steel up to 6mm in material thickness for heavier duty applications.
