Waterproof membrane

HDPE pre-applied membrane

HDPE pre-applied membrane is a mainly made of high density polyethylene resin,which cover with macromolecule self-adhesive film and sand or PE/PET. It can bond with concrete layer tightly. 


Construction Application

1.Surfaces should be clean,smooth and free from any dusts,oil.

2.The membrane can be directly paved on not fully cured concrete or on wet base surface .The reinforcing steel bar can be directly installed on the membrane, requiring no protection.

3.Pay more attention on the joint details treatment,press firmly onto the surface. The membrane must be overlapped at the edge.

4.After installation, a full serious inspection is required to make sure that all the edges and overlaps are getting proper seals.


Executive standards:
GB/T 23260—2009

material characteristic

1.Suitable to underground and tunnel construction and pre-applied waterproof construction.It has waterproof layer,steel bar can be directly installed on the membrane and requiring no protection.

2.Low flatness requirement to substrate,can shorten construction term.Cracks and surface irregularities no need to be filled with polymer mortar,can construct on wet base.

3.Simple and fast construction,flexible and flexible construction methods.

4.Environmental friendly: non-pollution.


application range

Underground construction baseplate,underground jamb wall.
