What is the use of Geotextile sheets in roofing works?

The Geotextile membrane fleece can be used in a number of ways:

1. The Geotextile can be used on top of the rubber membrane to protect it from sharp objects when it is planned to ballast (cover) the membrane with pebbles for fire protection.

2. Where a cement screed is being installed on top of the rubber membrane to provide a hard wearing surface for slabs or tiles the geotextile can be placed on top of the membrane to protect it from sharps in the screed.

3. The Geotextile fleece can be used under the rubber membrane when installing directly over the old roof to protect it from sharps that may puncture the rubber membrane. In this scenario the rubber membrane can not be glued in place so is either secured using Russ strips (A Grid of mechanically fixed bonding strips) or ballasted in position with pebbles or a green roof. This third method is only applicable to Classicbond.

To protect the waterproofing layer on the terraces or roofs

It used to prevent leakage of the sand under the roof tile so sand can not go in between roofing layers

This will protect the roofing tile and also protect water proofing from the sharp edges of the sand particles ofcourse
