 RC Guardex was introduced in Japan 16 years ago as a concrete preservative and waterproofing solution.  Less than two decades later, it is the preferred material for more than 60% of all concrete projects in the country.  It is also the exclusive concrete preservative of the bullet train infrastructure. 

New to the US, it is unlike anything available on the market.

Its better than a coating

Minimal Surface Prep


Bare absorbent concrete is the only necessity for concrete waterproofing.  If a coating is in place lets discuss options.  We have decades of experience removing coatings.

Application Perameters


As long as concrete is firm enough to walk on, it can be waterproofed.  Green concrete, wet concrete, dry concrete, oily concrete, cold concrete, hot concrete, it doesn't matter.  If water can absorb into the concrete, so can RC Guardex.

Not a Surface Solution


RC Guardex doesn't sit on top of the concrete as a traditional coating, which cracks and moves with the concrete.  RC Guardex penetrates deep into the surface to waterproof from within.

Minimal Cure Time


RC Guardex, concrete waterproofing, is typically ready for service within hours.  

Bring on the rain.

Easy Access


RC Guardex, concrete waterproofing, is applied by spraying a mist onto concrete.  It can be applied overhead, underfoot, from the inside out, or the outside in.

Maintains Flexibility


RC Guardex cures with water throughout its life and forms a flexible "gel-like" consistency.  Don't let it fool you though, this waterproof solution it isn't a densifier, but it could be.

save our infrastructure


Minneapolis Bridge Collapse

Our infrastructure is beyond its life expectancy.  What is protecting our concrete?  Certainly not the deicing that it sprayed onto it every winter.  It is time to protect our concrete by waterproofing it. 


Elliott Lake Mall Collapse

Parking structures are almost impossible to waterproof.  Coatings fall short and leave leaks to be chased for years.  It is time to waterproof our concrete without chasing every crack.
