In projects where durability and structural resilience are crucial, choosing the right foundation insulation makes all the difference. FORST® BOR is an LDPE membrane designed for horizontal insulation, protecting the structure against capillary rising damp and water penetration into the underground parts of the building.
Why do contractors rely on it?
- Waterproof performance confirmed by testing
- Resistance to soil and ground conditions
- Versatile application – suitable for insulating footings, foundation slabs, and basement walls
- Flexible roll width options
- High durability – thicker and more damage-resistant than standard horizontal insulation films
The photos show how FORST BOR is applied during the foundation stage: fast installation, stable material handling, and continuous insulation along the entire trench.
