LAMAFLEX
LAMAFLEX waterproofing membrane is manufactured from high-quality distilled bitumen modified with the Styrene Butadiene Styrene (SBS) to provide low-temperature flexibility. The carrier is reinforced by nonwoven fabric spun-bond polyester to give the membrane necessary elongation and to provide the required resistance to heat aging, puncture, and rotting.
The lower surface is covered with a burn-off polyethylene film, while the upper surface is covered with polyethylene film, or with a decorative mineral sand layer that also guards the membrane against damaging UV light.
Key Features.
- Excellent elasticity.
- High flexibility at low temperatures.
- Resistance to aging.
- High puncture and tear resistance.
- Good resistance to acids, sulfates, and chlorides.
Packaging Information.
- Dimension: 1×10 m/roll
- Thickness: 4 or 5 mm
- Weight per roll: 50 or 62 Kg
- Reinforcement: Nonwoven Polyester 180 or 200 g/m²
Application Field.
- Roofs (reinforced concrete, prefabricated concrete, metal and timber deck).
- Multi-story car parks.
- Underground foundations, basements, and retaining walls.
- Reservoirs, basins and canals.
- Swimming pools.
Application Method.
- Lay down the rolls so that the lower face with polyethylene film is bonded to the substrate.
- To fix the sheet to the substrate, use a propane gas burner to melt off the polyethylene film and a thin layer of bitumen while unrolling and laying the membrane. Side laps 100mm and end laps 150mm.
- The membrane may be loosely laid, partially or fully bonded, depending on the structure and the specifications.
