Polymeric Plastifelt is a waterproofing membrane composed of a high densitypolyethylene core covered on both sides with polymeric, plasto elasto bitumen based on APP/SBS and other selctedpolymers, constituting a (triple) continuouse and flexible water proofing layer.

Easy application and adaptability to the roof
Plasto elastic
Roof movement absorption
Flexibility at very low temperature
High temperature resistance
Practically no ageing

The rolls must be stored horizontally and parallel (not crossed) and never stacked mroe than 6 rools high. The membranes must always be stored protected against weathering.

--> Waterproofing of roofs trafficable and non trafficable, both traditional and inverted.
--> Waterproofing of foundations, basements and underground jobs.
--> Waterproofing of swimming pools, tanks, and reservoirs.

Instruction for Use
In general, the usual procedures for continuous water proofing are followed, and application should be carried out by specialized personnel.

Application System
Polymeric Plastifelt can be applied either fully bonded or loose laid, depending on the protection and slope.

Ploymeric Plastifelt is applied torched on, using a propane or butane gas torch.

The substrate receiving the polymeric plastifelt membrane must be firm, dry, clean and free from badly adhered materials. It must also be even and smooth, without any elements that should damage the membrane.

Application of the Membrane
To adhere the membrane to the surface of the substrate three procedures can be used

--> Loose laid
--> Preming with asphaltic paint, and then flame bonding.
--> Hot polymeric bitumer.

Overlaps between membranes are then carred out, with a minimum width of 8 to 10 cm, melting the bitumen with a torch to ensure correct adherence.

The membranes are staggered in sucha away that four membranes are never overlapped at one point.

A quality exceeding the surface to be waterproofed of between 12 and 15% is recommended.

Two applications can apply approximately between 100 and 400 m2 per day, depending on the complexity of job to be carred out.

The Added Advantages, when used for Canal Lining Purpose are :

--> Prevention of canal erosion, subsequent elimination of maintenance costs.
--> Reduced power consumption for pumping by way of reduction in friction losses.
--> Elimination of water losses caused by rodents and river carbs.
