Foundation & Basement Drainage Protection System
Drainage Board is a high-performance protection and drainage layer designed to ensure the controlled removal of water from structures in contact with soil, such as foundations, basements, and terraces.
It prevents water accumulation and reduces hydrostatic pressure, thereby protecting the waterproofing system and extending the service life of the structure.
PRODUCT STRUCTURE
Drainage Boards are typically manufactured from:
- High-density polyethylene (HDPE)
- Polypropylene (PP)
Their specially designed surface features protrusions (dimples) and drainage channels that create an effective drainage gap between the soil and the structure.
HOW IT WORKS
The dimpled structure:
- Reduces soil pressure against foundation walls
- Creates a continuous drainage channel
- Directs water safely away from the structure
- Prevents hydrostatic pressure build-up
By minimizing water accumulation, it protects both the waterproofing membrane and the structural elements.
KEY BENEFITS
- Prevents water accumulation around foundations
- Reduces hydrostatic pressure
- Protects waterproofing membranes from mechanical damage
- Extends the lifespan of waterproofing systems
- Reduces structural stress and cracking risk
- Easy and fast installation
APPLICATION AREAS
Drainage Board is ideal for use in:
- Foundation walls
- Basement walls
- Retaining walls
- Soil-contacting slabs
- Terrace drainage systems
- Underground structures
It is an essential complementary product for below-grade waterproofing systems.
WHY USE DRAINAGE BOARD WITH WATERPROOFING MEMBRANES?
Combining Drainage Board with bituminous waterproofing membranes:
- Enhances overall system performance
- Prevents membrane damage during backfilling
- Improves long-term structural durability
- Provides safer and more professional waterproofing solutions
