Single Side Self-adhesive Bitumen Membrane

DY-Self-adhesive Waterproof Membrane Finished Aluminium film

Advantages

1. self-adhensive membranes can bond firmly with base and avoid the phenomenon of water breakthrough effectively.

2.self-adhensive membranes can bond firmly with cement mortar protective layer of upper layer and avoid flake, detachment of the protective layer.

3.The products are not influenced by wet construction base surface, constructing without water

4. membranes are belong to high molecular material, ensure engineering service life even if they are not degraded for few years, as when the waterproof without atmosphere, ozone ,ultraviolet.

5.Shall not use base primer, hot melting when constructing, construction safety and be environmentally friendly.

6.Simple operation, economical and practical.

Applications

Used for waterproof working on the basement, roof and ground of industrial and civil architecture, especially for subway, tunnel and waterproof project constructed in rainy season.

Installation

1.Clean the base surface: clean dust sundries, draw membranes laying base line.

2.Smear cement mortar or grout: sprinkle water first if the base surface is dry, then smear polymer emulsion grout or cement mortar.

3.Lay  membrane: tear isolating membrane under the membrane as lay on the cement mortar. Parallel butting or lapping up and down between the membranes. Iron out the membranes upper surface gradually with pressing roll extract fillerexpel air of lower surface in order to bond tightly between the membrane and cement mortar.

4.Pressurize interface: pressurize with hermetic heal or polyurethane sealant. Clean up first if the butt parts are polluted.

5.Construct on vertical plane: construct on vertical plane after constructing on plane. Vertical plane construction can paste with grout, fasten with steel nail.

6.Close up: fasten the edge of sheets back cut with aluminum alloy or steel nail, pressurize back cut with specialized sealant.

Cautions

1.Shall not damage the sheet with steel or hard objects.

2.Shall strengthen waterproof layer protection when tie steel or pour concrete.

3.Shall not construct on the base with pollution, water ,ice.

Transportation & Storage

1.There should be no more than 5 layers if set horizontally.

2.Be under the dry and well-ventilated condition; avoid sunlight and raining.

3.Forbid meeting with oil and organic solvent, keep it away from fire.

4.Shelf life: one year.
