The main function of the No-Crack membrane, consisting of an HDPE studded layer with a roughened surface and a spunbonded polypropylene fabric, is to act as a bridge between the screed and the tiles.
The disconnecting function
Temperature fluctuations in open spaces and the constant presence of moisture in closed environments such as bathrooms put a strain on the stability of the screed, which “lives”, even after many years, and risks revealing tensions and cracks. As a result, over time fissures may appear in the tiles.
The studded structure of the membrane neutralises tensions below and prevents any cracks from reaching the tiles, thereby keeping them intact.
In other words, No-Crack ensures that the tiles are not in direct contact with the screed and do not move with it.
But that’s not all
This membrane also offers other advantages: when used in conjunction with the T-Bandel accessory, it provides a waterproofing function This application is highly recommended in outdoor environments subject to moisture seepage, significant temperature fluctuations and heavy loads (e.g. tables or cupboards on terraces) in order to protect the underlying substrate by keeping it dry and protected at all times.
Easy and speedy intervention works
If the screed has to be redone (in new buildings) or rebuilt following deterioration, intervention works can take a long time. No-Crack reduces the time required, as it can be tiled over after just 48 hours (compared to 28 days for intervention works without using this product), therefore allowing occupants to remain in their homes.
This is because the membrane layer separates the screed from the tiles, giving it plenty of time to stabilise without interrupting intervention works.
