HDPE Dimple Board Engineered for Maximum Waterproofing Performance

💧

Hydrostatic Relief

The dimpled geometry creates an instant air gap, forcing water to flow vertically into your drainage system rather than pressing against the wall. This effectively eliminates hydrostatic pressure and keeps structures dry.

🛡️

HDPE Material

Superior to traditional polystyrene. High-Density Polyethylene is impervious to aggressive soil chemicals, resists root penetration, and will not rot or degrade over time, ensuring decades of protection.

🏗️

High Impact Protection

The robust structure of Drainmat BG provides a critical layer of defense, protecting delicate waterproofing membranes from punctures and damage during demanding backfilling operations and site work.

Installation Workflow

1. Preparation

Clean the substrate. Drainmat BG is flexible enough to create a bridge over minor cracks and imperfections, preparing the area for quick application.

2. Application

Unroll horizontally or vertically. Fasten mechanically at the top edge according to product specifications. The dimples must always face the waterproofing membrane/wall.

3. Backfill

Immediate backfill capability is allowed. No curing time is required, allowing construction teams to proceed quickly while the structure is protected instantly.

Trusted by Professionals

"Drainmat's compressive strength gave us the confidence to backfill immediately, saving us two days on the schedule. It's the most reliable foundation protection we've used."
