The construction system is for underground retention wall, consisting at least partly of pile elements. Piles (6, 8) of a non-hardening sealing material, e.g. mixtures of clay minerals, etc. are driven at relative distances. The spaces between the plies are then bridged by rigid sealing wall eleemnts (7, 9, 11). These are placed, so that their joints are located within a pile. The wall elements may be formed of hardening material, e.g. concrete, reinforced concrete. USE/ADVANTAGE - Safer and more reliable retaining wall construction method, esp. In contaminated ground.
