The principle: Nondetachable and safely anchored

The BKU system consists of the standardised material PVC hard. The lining profiles have a width of 314mm and can be produced in any required length. They are connected using clip rails with an in-built elastomer sealing profile. Drop-shaped webs are fixed to the back of the profiles which solidly anchor into the building component already during concreting. Detaching from the concrete is thus excluded even in case of high external water pressures.

PVC hard. Proven "reinforced" material properties.

As required by the Institute for Building Engineering in Berlin for linings. PVC hard is impervious to concrete-attacking substances and highly resistant to foreseeable actions, e.g. mechanical, thermal, and chemical actions.

High abrasion resistance

The high abrasion resistance can be seen from the fact that a still sufficient wall thickness is given even after 1 million loadings - this corresponds to a lifetime of 100 years.

Areas of application
The BKU system is used for:

• Concrete pipes DIN 4032
• Reinforced concrete pipes DIN 4035 (for open and closed construction)
• Egg-shaped sections
• Reinforced concrete frames
• Ground slabs (as shells or egg-shaped sections for dry weather flow for steel pipes)
