CHEAPER IS NEVER BETTER!

Especially when it comes to Waterproofing, check the project we had to remediate at Sydney University. Our first site visit 03/07/18 - Note the water pooling



Report: Madsen Building Roof

The previous installer has broken several waterproofing codes of practice.

Full Spec Group was out priced by a competitor, we stated we would remove the existing membrane back to the sub floor. Our competitor decided to torch membrane directly on top of the existing membrane. Our second site visit 26/08/19 - Note the water pooling in the same place.

The gutter channel – Two-layer torch on system was installed; the sub floor was not correctly cleaned and sealed.

Half the floor had Liquid membrane installed and went over the torch on membrane.
