An economical and reliable method of hydrostatic sealing
PSI wallcollars are used for the hydrostatic sealing of pipes made of steel, cast iron, copper, plastic, fibre reinforced concrete, concrete and vitrified clay that pass through walls, ceilings, floors, shaft openings, swimming pools and groundwater tanks.
