DonProof L
High-performance, pre-applied, loose laid PVC membrane for below-grade waterproofing
DonProof L is a high quality, homogenous, flexible PVC waterproofing membrane manufactured from plasticised PVC. It features a light-coloured signal layer on the top surface and is specifically developed for use in underground structures.
The membrane is installed loose-laid and welded with hot air to create a watertight, continuous system.

- Excellent mechanical properties.
- High resistance to micro-organisms and root penetration.
- The light-coloured top layer allows for quick and reliable visual inspection during installation.
- Flexible in cold temperatures.
- Strong joints achieved through hot air welding.
- Recyclable, low carbon footprint.
- No open flame welding, enhancing safety during installation.
DonProof L is designed for the waterproofing of a wide range of elements including:
- Tunnels.
- Foundations and retaining walls.
- Vertical and horizontal sealing of below-grade structures.
- Terraces.
- Covered or protected roof applications.
DonProof L has a shelf life of 18 months from the date of manufacturer if stored in their original packaging at temperatures between 5oC and 30oC, and kept dry and protected from direct sunlight, snow, ice, water, heat or heat sources.
