MAXSEAL FOUNDATION: Cement-Based Waterproof Coating for Underground Structures
Proven Protection Against Groundwater for Below-Grade Concrete and Masonry
MAXSEAL FOUNDATION is a high-performance, cement-based waterproof coating engineered specifically for the harsh conditions of exterior underground applications. Formulated with special additives and selected aggregates, it creates an integral, permanent barrier within concrete and masonry substrates. Its unique chemistry allows it to effectively seal against both positive and negative water pressure, making it a fundamental solution for preventing water ingress in below-grade structures. Unlike surface-applied membranes, it becomes part of the substrate itself, filling pores, voids, and missing mortar lines to block moisture penetration at the source.
Superior Adhesion and Chemical Resistance for Long-Term Performance
The key advantage of MAXSEAL FOUNDATION lies in its exceptional bonding capabilities and inherent durability. It achieves tenacious adhesion to medium and high-porosity substrates, effectively becoming a monolithic part of the structure. This coating is specifically designed to resist aggressive groundwaters, unaffected by sulphates, chlorides, and other acidic salts commonly found in soil. Its cementitious nature allows it to be rendered over or painted, providing flexibility for final finishes. The application process is simplified as it requires no primers and must be applied to a wet surface, ensuring optimal hydration and cure.
Essential for Critical Below-Grade Waterproofing Applications
This product is the go-to solution for a wide range of foundational and subterranean waterproofing challenges. It is critically specified for waterproofing retaining walls, basement walls, and elevator pits where constant groundwater pressure is a concern. It serves as an effective barrier against capillary rise (damp-proofing) in foundations and masonry walls. Its reliability also makes it suitable for car parks, underground vaults, and any concrete structure subject to soil contact and moisture ingress, providing a robust first line of defence against water damage and the associated degradation.
Straightforward Application and Trusted Technical Support
Supplied in 25kg bags and 14kg handipacks, MAXSEAL FOUNDATION is mixed with water to a thick, creamy consistency and applied in two specific crosswise coats with a brush or broom to ensure deep penetration. A key requirement is curing on a pre-wetted surface, with a total consumption of approximately 2.5kg/m². Backfilling can proceed after 3 days of curing. As a product from Scientific Waterproofing Products, it is backed by extensive technical data and a 24-month shelf life, offering a dependable, cost-effective, and long-lasting waterproofing solution for the most critical below-grade applications.
