Thoroseal Waterproofing
Protecting concrete and masonry substrates with industry-leading cementitious coatings. We provide specialized Thoroseal application services for residential and commercial structures, resisting high hydrostatic pressure and ensuring long-lasting moisture protection for below-grade and vertical surfaces.
Why Choose Golden Stone Construction
Thoroseal is a heavy-duty, cement-based waterproofing coating designed specifically for concrete and masonry substrates. Unlike surface paints, Thoroseal becomes an integral part of the wall when fully cured, filling and sealing pores to stop seeping water and even reducing radon gas infiltration. Its unique formulation allows it to resist both positive and negative hydrostatic pressure, making it an ideal solution for basements, foundations, and water-retaining structures.
We specialize in the technical application of polymer-modified Thoroseal systems that offer superior adhesion and durability. Our team ensures meticulous surface preparation—removing efflorescence and contaminants—before applying the coating to a saturated-surface-dry substrate. Whether protecting a new foundation or restoring an aging masonry wall, our Thoroseal treatments provide a breathable, weatherproof barrier that prevents moisture damage while allowing internal vapors to escape.
Services Overview
Our specialized division delivers high-performance masonry protection using tested Thoroseal products and professional brush or spray application methods. Every project is engineered to withstand the specific moisture loads of your building’s environment.
Foundation & Retaining Wall Protection
Sealing below-grade concrete and cinder block walls to prevent seepage, mold growth, and structural deterioration.
Positive & Negative Side Waterproofing
Applying coatings to either the exterior (positive) or interior (negative) of a structure to block water ingress under significant pressure.
Water Tank & Cistern Lining
Utilizing Thoroseal’s durable, non-toxic properties to waterproof potable water storage and water treatment facilities.
Highlight Features
- High Hydrostatic Resistance: Formulated to withstand up to 72.5 psi of positive pressure and 10 psi of negative pressure, ensuring stability in flood-prone areas.
- Breathable Polymer Modification: Often modified with acrylic additives to enhance flexibility and allow the substrate to "breathe," preventing coating failure from trapped vapor.
The Results
- Permanent Structural Bond: Because it is cement-based, the coating fuses with the masonry, becoming part of the wall rather than a thin, peelable layer.
- Mold & Mildew Resistance: The dense, waterproof finish inhibits the growth of fungi, contributing to a healthier and cleaner indoor environment.

Still Have Questions?
We’re here to help you!
Can Thoroseal be applied to previously painted walls?
No. Thoroseal must be applied directly to clean, bare masonry or concrete to ensure a proper bond; all existing paint or oil must be removed first.
Is Thoroseal suitable for drinking water tanks?
Yes. Certain Thoroseal formulations are specifically designed and approved for use in water cisterns and potable water structures.
How long does it take for Thoroseal to fully cure?
While it sets relatively quickly, the system typically requires 12 hours between coats and a full 7–10 days of curing before it can be immersed in water.
