Torch Applied Bituminous Waterproofing Membrane
DESCRIPTION
A quality torch applied membrane manufactured from premium grade heavily modified bitumen, reinforced with a core of non-woven polyester fabric that gives good waterproofing properties.
USES
For flat or pitched roofs, basements, floor slabs, car parks, tunnels and subways, foundations, and concrete retaining structures. Can also be applied in new constructions and the renewal works.
ADVANTAGES
- Resist stresses due to building movement,
- Easily installed by flame torching method,
- Has good flexibility,
- Durable system for hot climates.
INSTRUCTION FOR USE
Surface Preparation and Priming
The area is to be waterproofed must be smooth, clean and free from defects or irregularities, which might damage the membrane, use a wire brush or broom to remove dirt, dust or any residues, then apply one layer of Deltaproof Primer on the surface with a rate of about 250 – 800 grams/m2, depending on the porosity of the surface, and then let it dry thoroughly.
Application
The membrane is then unrolled and placed in the correct position where it is to be torched on later. During each stage, each roll must overlap the next layer at least 8 cm. The membrane is then re-rolled again without changing the given orientation, and then it is very slowly unrolled again and lightly heats the surface transversely, by means of propane gas torch, which will cause surface melting for subsequent adhesion to the concrete surface.
PROTECTION
For roofing or other structures directly exposed to ultra violet light, it is suggested that Deltatorch 3000 is protected with 2-3 cm of cement screed
