Product Details

Weidun® 006 HDPE Waterproofing Membrane is widely used in underground and basement waterproofing projects. Membrane closed combined with concrete substrate gives the best waterproofing membrance 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® 006 HDPE Waterproofing 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 environmental damage.

Monitor environmental conditions during storage, handling, and application.

FAQ’s

Frequently Asked Questions

Clear, honest answers about how our Product.

How long can pre-applied HDPE waterproofing membrane last?
When correctly selected and installed as a pre-applied fully bonded waterproofing system, HDPE membrane is designed for long-term below-grade waterproofing and can provide a service life of more than 20 years. Actual performance depends on product specification, installation quality, detailing, concrete placement and project conditions.
Which side of pre-applied HDPE membrane should face upward during installation?
For sand-surfaced pre-applied HDPE membrane, the sand-coated bonding surface should face upward toward the concrete to be poured. Fresh concrete bonds with the specially designed surface, forming a continuous skin-like waterproofing layer between the membrane and the structure.
How does pre-applied HDPE membrane form a waterproofing system with concrete?
The membrane is installed before the structural concrete is poured. After concrete placement, the bonding surface of the membrane develops a continuous bond with the concrete, creating a fully bonded waterproofing layer. This helps reduce the risk of water migrating laterally between the membrane and the concrete structure.
Does pre-applied HDPE membrane need a protective screed before concrete pouring?
In a properly designed pre-applied system, the membrane is intended to receive the structural concrete directly after installation, detailing and inspection. Site traffic and reinforcement work should still be controlled carefully to avoid puncturing or damaging the membrane before the concrete is poured.
Where is pre-applied HDPE membrane commonly used?
Pre-applied HDPE membrane is commonly used for basement slabs, below-grade walls, foundations and other blind-side waterproofing applications where the membrane is installed before concrete placement and becomes bonded to the structural concrete.
