Our Solutions

Cold-applied polyurea-based membranes are used in either a spray-on or a roll-on application, depending on area size and accessibility. In case of a concrete flat roof, crack repair and patching are done, as needed, ahead of the waterproofing membrane installation. 

Application Benefits

01
Adaptability
A roof waterproofing membrane can be rolled on or sprayed on depending on roof size and accessibility: for small areas (e.g. roof overhangs) or for a high-rise roof, a roll-on application is appropriate, while for a low-rise industrial-type building roof, a spray-on application is ideal (large areas will be covered quickly, and the hose connected to a spray machine will be able to reach the entire roof surface).
02
Temperature Range and UV Protection
Polyurea-based membranes used in roof applications can be applied at temperatures as low as -5°C and are available as both aromatic (non-UV) and aliphatic (UV-protection).
02
Customised Applications
Specialised, industrial-grade materials allow for application thickness and curing time to be adjusted, as required. The waterproofing membrane will cure at any rate between 30 seconds and four hours, depending on the application method.

Repair methods

01
The roof surface must be prepared ahead of a polyurea-based waterproofing membrane installation. This usually involves the removal of gravel, rigid insulation and fleece, and the cleaning of the concrete surface. Crack repair and patching are done next, as required. The membrane is then either sprayed on or rolled on, depending on project requirements. If gravel is not used for UV protection, an aliphatic (UV-protection) topcoat is applied; otherwise, a less expensive aromatic (non-UV) topcoat is used.
