What is Dimple Board?
Dimple board is a dimpled waterproofing membrane typically used in below-grade applications. Made from high-density polyethylene (HDPE) or other materials, it features raised dimples that create an air gap between the membrane and the wall. This air gap allows for effective drainage and ventilation, preventing moisture buildup that can lead to structural damage.
How Dimple Board Works
Dimple boards function by channeling water away from the foundation walls. The dimples create a space that facilitates drainage, allowing water to flow down to a drainage system. This mechanism helps alleviate hydrostatic pressure that builds up against foundation walls, reducing the risk of leaks and water damage.
Benefits of Using Dimple Board
- Effective Drainage: Dimple boards promote efficient water management, helping protect foundations from water damage.
- Structural Integrity: The rigidity of dimple boards supports the structural integrity of walls while preventing moisture ingress.
- Easy Installation: Dimple boards are designed for straightforward installation, making them suitable for both DIY enthusiasts and professionals alike.
- Longevity: Made from durable materials, such as HDPE, dimple boards are resistant to degradation and can last for many years.
- Breatheability: Certain dimple boards allow for moisture to escape while preventing water from entering, promoting a healthier environment for buildings.

Installation Best Practices
When installing dimple boards, consider the following best practices:
- Surface Preparation: Ensure that the surface on which the dimple board will be applied is clean and free of debris.
- Overlap Edges: When installing multiple pieces, ensure edges overlap to prevent water from seeping through seams.
- Seal Joints: Use compatible sealants at joints and penetrations for added waterproofing.
- Drainage Systems: Incorporate a drainage system at the base of the dimple board to direct water away from the foundation.
