DDL PQZ wall sleeves
Wall sleeves made of polymer-quartz-sand cement
DDL PQZ wall sleeves are designed to take in seal inserts for pipe and cable penetrations sealed against pressing water. Due to the extremely homogeneous consistency of their material – compared to conventional wall sleeves of fiber cement – our PQZ sleeves perfectly seal penetrations against pressing water, especially when installed as a building entry.
They are furnished with circular grooves and so compound very well with concrete. The dimensioning of the wall sleeves in diameter, wall thickness and their tolerances as well as the arrangement and layout of the grooves correspond to the works standards of one of the biggest German water suppliers.
