Long-term Waterproofing Solutions for Water Tanks

Waterproof Your Concrete Tank with 2020's 'Most Innovative Product'

Flexible integral waterproofing systems can help architects achieve watertight results in existing concrete structures, while maintaining the original design & appearance. You will learn how TechCrete 2500 Waterproofing Agent (voted Most Innovative Product for 2020 at the World of Concrete Convention) actually uses water to increase its performance over time.

Water tanks are an ideal application for TechCrete 2500, since it uses water to penetrate below the surface, and then reacts with the free calcium found in concrete, to form a calcium silicate gel that fills & waterproofs the naturally occurring cracks, pores and capillaries.

This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions, ultimately protecting the steel reinforcement bars from corrosion. TechCrete 2500 works with water (using water as a catalyst), unlike traditional coatings or membranes that generally do not react well to the constant presence of water. It provides a flexible waterproofing system, capable of handling the building movement associated with thermal stress. TechCrete 2500 Waterproofing Agent is certified as potable water safe (NSF-61), and is safe for fish, plants, and aquariums.
