G-FLEX is a waterproof, anti-fracture decoupling sheet that is formed by a polyethylene membrane joined to a geotextile sheet, leaving between them nodules of free air in the shape of circles. Thanks to this, the result of the coating of ceramic tiles and natural stone exterior and interior is improved, highlighting the efficiency when installed on critical substrates; cracked, with a lot of movement or with possible vapor stresses due to residual humidity.

G-FLEX sheet waterproofs any surface, whether old or new, wet or dry and cracked or subject to dimensional movements. This happens thanks to the compensation that this bonding sheet produces by hygrometric shrinkage and thermal expansion. It also does not have problems with the joints, since it is not necessary to respect the joints of the supports in large installations.

One of the highlights of the G-FLEX sheet is that it reduces construction times since the waterproofing and the laying of the coating are without delay, that is, the installation is immediately passable.

Waterproofing and uncoupling polyethylene sheet G-FLEX

Lamina de poietileno G-GLEX G-FLEX

GURU G-FLEX Polyethylene Sheet is made up of raised circular patterns. The back of the sheet is covered by a geotextile sheet that acts as a waterproofing sheet. This uncoupling sheet compensates for the vapor pressure in the event that moisture appears on the support and causes the effect of uncoupling on cracked or highly moving substrates.

Properties of the uncoupling sheet G-FLEX

1. De-solidarity

The configuration and distribution of the nodules allows the articulation of deformations in all directions, maintaining the punctual distribution of the loads and damping the stress due to horizontal movements and deflection.

2. Steam and humidity management

The arrangement of the nodules forms a channeling network that allows vapor pressure to circulate and dissipate, helping to dry up excess moisture.

3. Decoupling

The HDPE sheet ensures the physical separation between the support and the coating.

4. Better heat distribution

In the case of installation with underfloor heating, the channeling network makes it easier for the heat to be distributed more quickly and evenly.

5. Load sharing capacity

When installing ceramic tiles or natural stone pavements on the G-Flex sheet, the cavities of the nodules are filled with glue cement, forming small pillars that, when harden, support the loads and transfer them from the coating to the firm support distributed at multiple points.

6. Waterproofing

G-Flex installations can also be done for waterproofing. As the HDPE polyethylene sheet is totally waterproof, it is necessary to seal the joints between sheets and the deliveries between the floor and the wall with a WATER-STOP WS BAND band glued with polymeric waterproof cement.
