Why Is Radcon Concrete Waterproofing So Popular?

Most people encounter concrete on a regular basis and never give it much thought. However, in the sealer industry, we know there’s a lot that goes into ensuring the look and performance of concrete surfaces, a huge factor at play being the sealant used. The problem with most concrete sealants is that they sit on top of the concrete’s surface like a membrane. Over time, the sealant is washed or worn away due to weather and traffic, leaving the concrete susceptible to cracking and damage. Repairing concrete can become a costly, time-consuming job, so having it last and be durable is a must. That’s where Tecnorap USA’s Radcon Formula #7®‘s revolutionary concrete waterproofing capabilities come in.

Radcon is a concrete sealer and waterproofing agent like no other. It’s the only sealer that works within the concrete rather than sitting on top. It’s odorless, colorless, non-flammable, non-toxic, biodegradable, and highly effective. It quickly works below concrete’s surface to fill cracks, pores, and capillaries, and it’s made to last. Radcon’s performance has been successful in commercial and industrial areas, reservoirs and treatment plants, parking lots and garages, water-holding vessels, bridge decks and raised freeways, airport runways, rooftops, and podium decks.

How Does Radcon Work?

The way Radcon concrete waterproofing works is simple. When applied to concrete, it forms a calcium-silicate-hydrate gel complex that reacts with any moisture found in cracks and pores. The calcium then reacts with the atmosphere to produce a low-calcium gel depositing calcium carbonate, which fills in the spaces within the concrete. The gel looks for more calcium, which it gets from any cement hydration. This process repeats until there’s no moisture left, keeping concrete safe from damage.

Radcon’s Other Benefits
