Lining softens, blisters or leaks in a sewage-treatment chamber.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Lining softens, blisters or leaks in a sewage-treatment chamber.
Identify chemicals, pH, immersion, abrasion, pressure and actual substrate condition.
A waterproof membrane may lack chemical resistance to process liquids and cleaning cycles.
Specify a lining proven for the chemical exposure together with joint and crack treatment.
Prepare concrete to required profile and moisture limits; control cure before immersion.
Verify lining continuity, thickness and holiday or spark testing where applicable.
Do not assume a potable-water tank coating is suitable for STP chemical exposure.
