Questions about the order

A successful construction project is ultimately completed with our RENOLIT ALKORPLAN through an on-site installation carried out by a specialist. As we are the manufacturer of the swimming pool liner and we don’t carry out the liner installations ourselves, we will be happy to provide you with contact details of the liner specialists in your area.

We distribute swimming pool liners exclusively through swimming pool wholesalers.

The delivery periods for the membrane depend on the colour and product type, as well as the effective date on which the membrane order is processed. We supply the swimming pool market through specialised wholesalers. Unfortunately, we cannot directly influence the delivery periods of the goods to the swimming pool builder.

We are not able to cut them to size in our factory. However, our wholesalers cut the anti-slip laminates into linear metres and deliver them to pool constructors

Questions about the product

For the construction of public swimming pools, we have 2.05m wide reinforced membrane for a faster and more optimal installation. RENOLIT ALKORPLAN2000 it is available in 1.65m or 2.05m width.

Given that RENOLIT ALKORPLAN TOUCH is 2-mm thick, a 25-m long roll with a width of 1.65 m would exceed 100 kg/roll, thus going over the transport and storage limit. We have therefore decided on a roll which is 21-m long with a width of 1.65 m. Thanks to the optional butt-welding installation, cross-sectional positioning is possible, and seams are practically invisible. This enables an excellent way of working with the 1.65-m rolls available.

Questions about water treatment

Our fabric-reinforced waterproofing membranes comply with current regulations, with a maximum operating temperature of 32°C. However, proper pre-tensioning during installation allows a maximum and constant water temperature of up to 35°C. Download our care and maintenance guide for your RENOLIT ALKORPLAN membrane in our

You don’t have to worry about this. Obviously, there are much higher temperatures and UV radiation at the top or above the water line.

Our liner formulas are adapted to withstand these conditions.

Thus, coatings with the same formulation can also be used in Africa or South America without any problems.

Yes, it is compatible.

In case of automatic treatment with chlorine, electrolysis or hypochlorite injection, a stabilizer is required.

It is recommended that the salt electrolysis equipment has, in addition to a PH probe, an ORP control probe.

Non-stabilized chlorine (free chlorine obtained by salt electrolysis or sodium hypochlorite injection, etc.) should be administered at a ratio of 0.3-0.8 mg/l at a pH between 7.2 and 7.6.

In this case, it is essential to add 20-30 ppm of stabilizer to limit the oxidizing power of the water or the RedOX potential.
