HDPE Waterproof Membrane
HDPE membrane is widely used in underground and basement waterproofing projects.
Membrane closed combined with concrete substrate gives the best waterproofing performance.
Area of Application:
It is commonly used in:
- Underground projects
- Basement projects
Durable
Highly durable and resistance to punctures
UV Resistance
Excellent resistance to UV radiation, ozone and chemical exposure
Strengthy Bond
Heat welded seams create strong bonds, enhancing the overall strength of roofing system
Recyclable
It is environmental friendly as compared to other roofing materials
Product Details
HDPE Waterproof Membrane is widely used in underground and basement waterproofing projects. Membrane closed combined with concrete substrate gives the best waterproofing performance.
Weidun Waterproof has a full line of HDPE waterproof membranes.
Length and width can be customized.
The membrane fully bonds with concrete
Maintain high peel strength in soaking
Uses
Weidun®003 HDPE pre-applied sheet membrane is designed for areas that need to be waterproofed such as basement, balconies.terraces and green roofs.
How to Use
Surface Preparation
Ensure that the surface is clean, smooth, and free from any debris and dust.
Membrane Preparation
Cut the membrane to the appropriate size and length as required. Before cutting the membrane, check for any damage or cracks.
Installation
Roll out the sheet onto the prepared surface, or install it as per the manufacturer’s instructions.
Welding
Use a hot melt welding machine to weld the membrane together.
Advantages
- HDPE membrane fully bonded with concrete;
- Low requirement of substrate;
- Puncture resistance,longer service life
- Maintain high peel strength in soaking.
Storage and Handing:
To prevent damage, support rolls on end in an upright position and store in a clean, dry location, covering as necessary to protect from environment damage.
Monitor environmental conditions during storage, handling, and application.
