Applications such as potable water tanks, sprinkler tanks, attenuation tanks, clean and dirty water systems require a specific approach to keeping water in and protecting groundwater against pollution.

Potable water tanks/pits and ponds

Potable water tanks and reservoirs can be protected in various ways including the use of Sikaplan® FPO sheet membranes. Joints and cracks in the structure are commonly sealed using the Sikadur®-Combiflex® SG system. All solutions offered are WRAS and DWI approved.


Primary and secondary sedimentation tanks

Retention pools, tanks of sewage water or chemical effluents require chemically resistant linings for protection of the subsoil and groundwater against pollution. Following the specific requirements Sikaplan® sheet membranes, Sikalastic® liquid membranes based on polyurethane or polyurea or Sikagard® epoxy coatings may be chosen.
