Self adhesive Roofing Basement Waterproof Membrane

Description

PCM bitumen roof wateproof membrane is a modified bitumen base sheet consisting of polymer modified asphalt added viscosifier inside covering with different upper separated materials and underside with silicone antisticking layer. According to different upper surface, it includes three types: PE film surfacing, sand surfacing and antisticking surfacing . There have two kinds of thickness: 3.0 mm and 4.0 mm.

Where to use

Roofs or undergrounds;

Swimming pools, fire pools and reservoirs;

Subways or tunnels;

Open fires-forbidden construction areas;

Cold construction areas.

Advantages

Typical properties

Packaging
 
PCM material is packed in rolls with plastic bags or cartons

Storage

PCM should be stored in well-ventilated place and avoid being exposed to the sun or rain. The temperature in stored places can not be higher than 45° C. It should be put vertically not more than in two levels.

Transportation

In order to prevent inclination or lateral drift, PCM can not be put vertically in double-level.

Application System

PCM adhesive waterproof system includes substrate, primer, membrane waterproof underlayment, protection layer.

PCM also provide a complete line of compatible accessories and components, including primers, pipe clamps, terminal battens and screws.

Surface Preparation

Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and uneven places need to be filled by polymer mortar.

Priming

Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.

Membrane laying

After substrate treating agent drying, lay PCM material according to application designs.

Sealing, fixing and constraining on vertical surfaces

On vertical surfaces, fix with metal battens and seal with sealants for membranes.

Application on protection layer

After membrane laying, apply on protection layer according to waterproof layer design.
