Leaking, cracked or tired pool?
Commercial pools take heavy use. Over time, tiles crack, plaster wears and leaks appear, and fixing the shell can mean long closures and big costs.
RENOLIT ALKORPLAN is laid over the existing surface and seals the whole pool in one continuous membrane. There's no demolition and less downtime, and you get a finish built for daily use.
It isn't the cheapest option. It's made for pools that see heavy use and can't afford to leak.

What is RENOLIT ALKORPLAN?
RENOLIT ALKORPLAN is a reinforced pool membrane made from two layers of PVC-P with a polyester mesh core. The mesh gives it strength, and the PVC keeps it flexible enough to follow every corner, step and curve.
It’s heat-welded on site into one continuous, watertight finish. RENOLIT describes reinforced membranes as the most widely used on-site pool liners in the world.
