PSI wallcollars are used for the hydrostatic sealing of pipes made of steel, cast iron, copper, plastic, asbestos free cement, concrete and vitrified clay that pass through walls, ceilings, floors, shaft openings, swimming pools and groundwater troughs.

PSI wallcollars are the ideal solution wherever it is not possible to retrofit sleeves or drill holes.
