Protecting your home’s foundation from water and moisture is critical for ensuring long-term structural integrity and a dry, healthy basement. The DELTA®-MS dimpled membrane by Dörken Systems Inc. is a top-tier solution for foundation waterproofing, utilizing exclusive Air-gap Technology to keep basements dry and durable. This comprehensive guide provides a step-by-step process for installing DELTA®-MS, along with expert tips to maximize its performance. Whether you’re a contractor or a DIY homeowner, this guide will help you achieve a professional-grade installation.

Why Choose DELTA®-MS for Foundation

Waterproofing?

The DELTA®-MS dimpled membrane is a high-density polyethylene (HDPE) sheet designed to protect foundations from water intrusion. Its vacuum-formed dimpled pattern creates an air gap that allows water to drain away from the foundation wall, preventing hydrostatic pressure buildup. Unlike traditional spray-on waterproofing, which can crack when concrete shifts, DELTA®-MS bridges cracks to ensure no water intrusions occur. Made from 60% recycled and 40% virgin HDPE, it offers superior compressive strength and durability, making it ideal for residential and commercial applications.

Key Benefits of DELTA®-MS

Permanent Protection: Keeps basements dry by creating a capillary break and allowing water to drain to the footing drain.
Durability: Combines virgin and recycled HDPE for high compressive strength and impact resistance.
Crack Bridging: Unlike sprays, it maintains waterproofing integrity even if the foundation cracks.
Eco-Friendly: Made with 60% recycled materials, supporting sustainable building practices.
Code Compliance: Meets building code requirements in the USA and Canada, including CCMC and ICC-ESR-2303 certifications.
Ease of Installation: No need for specialized safety equipment or curing time, unlike spray-on systems.
