PV™ 100
A unique multi-layer composite pre-applied waterproofing membrane that bonds integrally to poured concrete
Product Description
PV™ 100 pre-applied waterproofing membrane is a multi-layer composite waterproofing material with superior performance, including a layer of high-performance PE film, self-adhesive polymer layer and a unique particulate layer.
PV 100 pre-applied waterproofing membrane can be applied on a smooth level concrete surface, qualified compacted sand-stone cushion, or used as the waterproof layer of vertical surfaces of temporary and adjacent structures. After pouring concrete directly on to the paved PV 100 preapplied waterproofing membrane, the poured concrete will bond fully and permanently with PV 100 pre-applied waterproofing membrane.
PV 100 pre-applied waterproofing membrane protects concrete foundation against aggressive ground contaminants and is suitable for water and vapour-proofing for all basement grades.
PV 100 pre-applied waterproofing membrane is supplied at a width of 1.0m. Pour concrete after the steel bars are tied up. Please contact your local GCP representative for application details.
Product Advantages
- Forms permanent bond to concrete poured against it.
- Not affected by the displacement of the basal layer/ ground settlement beneath slabs
- Membrane is self-protecting. It can be trafficked immediately after application and does not require the use of protective layer
- Simple and quick to install, requiring no priming or fillets
- Unaffected by wet conditions
- Fully-adhered watertight dual laps with self-adhesive strip and detailing
- Excellent bonding even under long-term water immersion
Installation
Substrate Preparation
All Surfaces
It is essential to create a sound and solid substrate to eliminate movement during the concrete pour. Substrates must be regular and smooth with no gaps or voids greater than 12mm.
HYDRODUCT® drainage composites can provide the membrane with a good surface and facilitate underground structural drainage.
Horizontal Blinding
The substrate must be free of loose aggregate and sharp protrusions. Avoid curved or rounded substrates. The surface does not need to be dry, but standing water must be removed.
Vertical Sheet Piling
Use concrete, or 19mm thick plywood, insulation or other approved facing to sheet piling to provide support for the membrane. Board systems such as timber lagging must be close butted to provide support and not more than 12mm out of alignment.
Membrane Installation
When placing PV 100 pre-applied waterproofing membrane, overlap the bonding edge. Use a steel roller to press the bonding edge firmly to ensure complete bonding and to achieve continuity. PV 100 pre-applied waterproofing membrane can be applied at -4ºC and above. When installing PV 100 waterproofing membrane in cold or marginal weather, the bonding edge may be heated appropriately with hot air gun or similar devices to remove moisture in order to enhance bonding.
PV 100 Waterproofing Membrane
Place the membrane PE film side to the substrate with particulate layer side up, facing the concrete pour. End laps should be staggered to avoid build up of layers. Accurately position succeeding sheets to overlap the previous sheet 75mm along the marked selvedge. Ensure the underside of the succeeding sheet is clean, dry and free from contamination before attempting to overlap. Ensure a continuous bond is achieved without creases and roll firmly with a heavy roller. Any initial tack will quickly disappear.
Roll Ends and Cut Edges
Overlap all roll ends and cut edges by a minimum 75mm and ensure the area is clean and free from contamination, wiping with a damp cloth if necessary.
PV100 membrane has self-adhesive strips at the top and bottom of the seam area on the edge of the roll. Remove the liner of 2 strips and adhere them together, a strong adhesive to adhesive bond is achieved in the overlap area. Roll firmly to ensure complete adhesion without creases or voids.
Application with BITUTHENE® Membrane and Joints
If PV 100 pre-applied waterproofing membrane is applied together with Bituthene membranes, or for areas such as construction joints, allow for another 300mm-wide overlap so as to protect PV 100 pre-applied waterproofing membrane from being contaminated. This 300mm-wide membrane can offer overlap with the follow-up waterproofing membrane that is installed.
Pouring of Concrete
The concrete must be poured within 21 days of application of the membrane. During pouring, take care when vibrating concrete to avoid damaging the waterproofing materials.
Formwork Removal
PV 100 pre-applied waterproofing membrane can be applied to removable formwork, such as slab perimeters, elevator and lift pits, etc. Once the concrete is poured the formwork must remain in place until the concrete has gained sufficient compressive strength to develop the surface bond. PV 100 pre-applied waterproofing membrane is not recommended for conventional twin-sided wall forming systems.
As a guide, to reach the minimum compressive strength stated above, a structural concrete mix with an ultimate strength of 40N / mm2 will typically require a cure time of approximately six days at an average ambient temperature of -4ºC, or two days at 21ºC. Please contact your local GCP representative for more details.
