AMAN

AMAN waterproofing membrane, 4 or 5 mm thick, is a high-performing membrane.
AMAN membranes are manufactured from bitumen, modified with atactic polypropylene (APP).

The compound is a mixture of distilled bitumen, thermoplastic polymers and elastoplastic copolymer which gives the membrane excellent durability and flexibility at low temperatures, and the ability to withstand high temperatures. The reinforcement is of 180 g/sqm nonwoven polyester fabric to give high elongation and to provide the membrane with the required resistance to heat aging, puncture and rotting.

AMAN is manufactured with polyethylene film on the lower face to prevent sticking and which melts quickly when subject to flame during the application, which gives a visual sign of the correct melting temperature of the membrane. The upper face is covered with fine sand, granules, or colored slates when the membrane is used as the exposed top layer.

Key Features.

  • Single-ply waterproofing layer.
  • Fast, easy and clean application.
  • Can be applied to repair existing asphalt roofing systems.
  • Highly resistant to weathering.
  • Resistance to salt solutions, dilute acids, alkalis, sulfates and chlorides

Packaging Information.

  • Dimension: 1×10 m/roll
  • Thickness: 4 or 5mm
  • Weight per roll: 50 or 60 Kg
  • Reinforcement: Nonwoven Polyester 180 g/m²

Application Field.

Due to its excellent resistance and elongation, AMAN is used for a wide range of waterproofing applications such as:

  • Roofs (reinforced concrete, prefabricated concrete, metal and timber decks).
  • Roof gardens, terraces, kitchens, bathrooms, etc.
  • Underground foundations, basements and retaining walls.
  • Reservoirs, basins and canals.

Application Method.

  1. Lay down the rolls so that the lower face with the poly-ethylene film is leveled to the substrate.
  2. 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.
  3. Seams at overlaps should be properly secured and smoothed on with a hot round-tipped trowel.
  4. Side laps 100 mm and end laps 150mm.
  5. The membrane may be loosely laid, partial or fully bonded, depending on the structure and the specifications.
