Applications & Uses
- Applications
- Compatible Substrates & Surfaces
- Process
- DuraTite® Foundation reacts with water and free lime in the concrete to create a penetrating waterproofing crystalline barrier.
- The crystals fills the capillaries of the concrete and prevent moisture from passing while still allowing the concrete to breathe.
- DuraTite Foundation’s crystals will be fully developed and functional after 7 - 10 days.
- Even after the crystals are fully developed, the chemicals that penetrated the concrete store themselves within the concrete and activate when they come in contact with water.
- If a crack forms after Watertite Foundation is applied, the crystals will continue to grow and protect the concrete from water damage.
- DuraTite® Foundation can be used against negative and positive water or hydrostatic pressure and can be used on an internal or external surface.
- It is best practice to apply DuraTite® Foundation to surfaces which face direct water contact to encourage accelerate penetration and crystallization of the chemicals.

- Product Application
How it Works
When DuraTite® Foundation is used, the concrete must be clean. Remove laitance, dirt, grease, etc. by water jetting, wet sandblasting, or wire brushing. Cracked or honeycombed concrete must be removed or filled in with DuraTite Plug. Surfaces must be pre-watered before DuraTite Foundation can be applied. Contact the Technical Department for help and directions for which cleaning product will provide the best result for a clean surface. Where segregation or voids are apparent, chip out and treat with DuraTite Foundation. Once repaired, allow at least 24 hours for patches to dry and cure. Ensure that pores are open and roughen surface so the crystals can penetrate effectively. Surface must be damp before being treated. DuraTite Foundation should be applied to a wet surface to ensure proper penetration. Application should not be made when the surface temperature is below 41°F.
Application Rates
- Vertical Surfaces - 1.25 - 1.5 lb/yd²
- Horizontal Flatwork - 2lb/yd²
- Construction Joints - 4.2 - 6.59 lb/yd²
Application Method
DuraTite Foundation can be applied to any cement or concrete surface that is clean and wet. The mixture should be three quarts (liters) powder and one quart (liter) water (mix one part water and three parts powder). Then, continuously stir the solution. With a concrete brush, use an aggressive circular motion to coat the concrete with the solution at a coverage of .16lb/ ft ² (0.8kg/m2) per coat. To ensure that there is even coverage, it is recommended to use two coats. Wait until the first coat is hard but still green before applying a second coat (around 3 - 4 hours.)
Waterproofing Concrete Slabs
When there is a high water table, DuraTite® Foundation can be applied to binding concrete before casting the slab. Itwill prevent ingress of ground water from damaging the concrete. Any holes drilled to relieve water pressure should be sealed with Duratit Plug.
Existing Structures
Structures that are leaking should be inspected to find the leak. Any water should be cleared away. Clean tools and equipment after use. Plastic and rubber containers are recommended.
- Limitations
- DuraTite® Foundation is not an effective waterproofing system for joints that experience constant or repeated movement.
- DuraTite® Foundation will change the color of the surface it is applied to.
