PVC Waterproof Membrane

DERFLEX has successfully developed and produced a new type of environmentally friendly waterproofing membrane with unique 9A quality assurance according to market demand. The material has good physical and mechanical properties, excellent waterproof performance, temperature resistance, UV resistance, long service life, safety and environmental protection; no solvent and fuel are required during the construction process, avoiding environmental pollution and fire protection hazards, and saving energy; high tensile strength and elongation High, good stability, low shrinkage, good low temperature flexibility. Material construction is convenient, short construction period, no need to maintain after forming, not affected by temperature, low environmental pollution, layer thickness is easy to hold according to fortification requirements, material calculation is accurate, construction site management is convenient, layer thickness is uniform, and effective in empty paving Overcome the stress of the base layer (in the case of large cracks in the base layer, the waterproof layer can be maintained as a whole).

The new environmentally friendly waterproof membrane is suitable for building roofs, subways, culverts, subsea tunnels, planted roofs, water-proof and drainage systems, ponds, reservoirs, irrigation systems, light steel roofs and many other fields.

I.Why you should Choose PVC Waterproofing Membranes?

1.PVC waterproofing membrane (PVC = Polyvinyl Chloride) is a single-ply sheet requiring only one layer of the membrane.  PVC membranes have a wide range of benefits for any industrial, commercial or residential building, the most important being saving thousands in remediation, repairs, maintenance, or replacement over the expected lifespan of the building.

2. PVC Membranes have been in the marketplace for over 50 years using a constant formula & those that are supplied from Europe are governed by strict guidelines as to the chemical composition, formulation etc. These PVC sheet membranes are manufactured using superior raw materials chosen for strength and durability, giving PVC waterproofing membranes a very long service life.

3.Providing PVC sheet membrane products are installed correctly, they will provide long term waterproofing protection. These membranes can also be installed over damp substrates due to the water vapour transmission properties that are exhibited by these products. Obviously, PVC membranes don’t need any curing time to become waterproof and their thickness will always be consistent throughout the entire application. PVC sheet membranes protect structures immediately after their installation and finishes can be applied over them immediately.

4.PVC waterproofing membranes can withstand normal building movement because of their exceptional elongation attributes.  As an example, Wolfin Polyester/PVC membranes have the highest elongation of all PVC membranes. Its unique formulation incorporating Polyester with the PVC offers excellent chemical resistance & exceptional elongation properties. The Wolfin IB Membrane has an elongation of over 300% allowing a structure to move without tearing/splitting the membrane and thus maintaining the waterproofing integrity.

II.Other benefits of PVC waterproofing membranes:

1.Most finishes can be applied to the waterproofing membranes – this includes tiles on mortar beds, wearing slabs, pavers on pads, landscaping, decking, etc.

2.Suitable over most substrates including concrete, timber, steel, compressed fibre sheeting, etc.  Can even be installed over damp substrates.

3.Safe to apply – they are either loose-laid or self-adhesive and every lap joint is hot air welded, no need for naked flames and torches.

4.Ideal for landscape applications including Green Roofs and Planter Boxes, as it is certified (FLL) and tested resistant to aggressive root penetrations. See Case study.

5.Suitable for new and remedial applications such as below ground systems, balconies, exposed roofs, insulated roofs, planter boxes, green roofs etc.

6.Exceptional range of service temperature that allows them to remain flexible in both freezing & warm climates.

III.Application:

Waterproof Membrane is a woven plastic-based material used to make poly tarps that can cover a variety of items. They are flexible enough to use in applications ranging from road transport covers to dome shelters and roof sheets. The poly tarp is very common because it is so versatile.

1. Truck cover, Top roof and side curtain.

2. Our door event tent(blockout)

3. Rain and sunshine shelter, playground.

4. Army tent, carriage tent and house building.

5. Construction structure.
