BKU-aqua®: for water supply for new buildings and renovation

The material PEHD has been known and has proven itself for years for use in pipe systems for potable water. The Karlsruhe Technology Centre Water of the German Technical and Scientific Association for Gas and Water issued a test certificate for the used material PE-HD Finathene 3802, colour blue.

The lining board is a homogenous "web board" extruded in one pass and with a width of 1m and a wall thickness of 4mm. The front (with medium contact) has a smooth surface, the back is equipped with specially profiled longitudinal webs with a web height of approx. 12mm and fixed at a distance of approx. 30mm each.

New buildings

The BKU-aqua® boards have a tongue-and-groove joint system and are preassembled to the shuttering. This guarantees that the preassembled but not yet welded boards can adjust stressfree to expansion (change of length) or other site-related conditions caused by temperature variations.

After dismantling, the joints are joint-welded by TÜV-supervised specialists by using hot gas welding.

Subsequent changes of mounting parts, modifications, and extensions can be integrated non-destructively.

Renovation

The line-type frictional connection to the existing container is made with the PEHD subconstruction especially developed for the BKU-aqua® System.
This subconstruction for the BKU-aqua® lining serves the creation of the line anchorage and also serves as weld support of the boards in the area of the joint gap.

After the installation of the BKU-aqua® lining and welding of the joints, a "PEHD container" insensitive to cleaning and hygienically safe is created in the existing reinforced concrete structure.
