RENOLIT ALKORPLAN — Adhesive Fastening System

The adhesive method of fastening the RENOLIT ALKORPLAN membrane involves gluing the membrane as a topcoat to the entire supporting base area with mechanical fastening around the perimeter. For the adhesive system, we use a special membrane with a fleece backing RENOLIT ALKORPLAN A. The longitudinal seams (overlaps) of adjacent membrane sheets are not glued, but welded with a stream of hot air.

The Adhesive System Configuration:

When and why is there a need for the adhesive ​system?

On roofs where mechanical fastening causes problems (e.g. concrete structures) or even impossible, the waterproofing membrane can be attached by gluing the membrane to the roof deck. This method can be used regardless of the deck type (wood, concrete or steel).

This fastening system is recommended in situations where the vapor barrier layer cannot be perforated, such as indoor swimming pools and buildings with high interior humidity. The use of an adhesive system is also recommended, for example, for refrigerated or cooled buildings, as mechanical fastening can cause problems with thermal bridging and thus lead to damage caused by high humidity.

This system is also relevant due to the fact that only an adhesive fastening system can be used to repair old bitumen roofs made of ribbed roofing slabs with a large slope. In this case, mechanical fastening cannot be used, as it significantly weakens the bearing capacity of old, already thin-walled ribbed roofing slabs, and the ballast system is irrelevant due to the large angle of the roof slope, which means that the ballast cannot be held on the entire surface of the roof.

Where can you apply the adhesive system?

The adhesive system can be used in warm and inversion roof constructions, in new buildings, as well as in reconstruction projects. This type of fastening is most suitable for repairing old roofs - thanks to the fleece backing, the new membrane can be glued directly to the old waterproofing layer made of bitumen material or laminated geotextile layer (together with the PVC membrane).

Advantages of the adhesive system:

  • Fast and efficient to work with.
  • The adhesive can be used in all weather conditions.
  • The roofing membrane is fully adhered.
  • Can be used on roofs with any slope and configuration.
  • Allows to repair roofs without removing the old bitumen-based layer.

EUROROOFING professionals have undergone training in adhesive method membrane fastening, are certified and experienced in installation of these fastening systems. We are confident that our qualifications and the quality of the RENOLIT ALKORPLAN system will provide you with a reliable, durable, and efficient membrane fastening system for all types of roofs.
