Radcon Formula #7® Superior Concrete Sealer & Waterproofing Agent

Tecnorap USA’s Radcon Formula #7® is literally a product that has no competition. That’s because it’s designed to be a different kind of concrete sealer and waterproofing agent. Radcon Formula #7® is a colorless, odorless, non-flammable, non-toxic, biodegradable, clear liquid created to penetrate concrete surfaces, not sit on top of it. That’s where this solution is unique. Instead of covering concrete as a surface membrane, Radcon Formula #7® works below the surface as a gel that fills cracks, pores, and capillaries quickly. Its advanced biochemical technology allows it to seal cracks up to 2mm (1/16 inch) thick as well as reseal hairline cracks. Since it works from the inside, the product can’t be damaged or worn away, increasing its longevity and value. Traditional concrete sealers and waterproofing agents only rest on top of cracks as a way of keeping out water. Because of this, they wear out quickly over time through weathering, revealing the cracks again and again. With Radcon Formula #7®, you won’t have to worry about cracks coming back, saving you time and money on repairs.

How Radcon Formula #7® Works

Once applied to concrete, Radcon Formula #7® forms a calcium-silicate-hydrate (C-S-H) gel complex that reacts to any moisture in the penetrated area’s cracks and pores. The calcium then reacts with the atmosphere to produce a low-calcium gel depositing calcium carbonate, which fills in all spaces within the concrete. The low-calcium gel constantly seeks out more calcium, which it gets from the moisture and cement hydration. This process continues to repeat until water ingress ceases. This catalytic reaction is due to Radcon Formula #7®’s unique biochemical compounds.

Radcon Formula #7® Technical Information & Data Sheets

Radcon Formula #7® truly works like no other product. To ensure maximum effectiveness, it’s important to apply the product properly. To learn more about the formula’s performance capabilities and application requirements, or to view this solution’s data sheet and resources, use the tabs below.

Performance Characteristics
Radcon Formula #7® permanently seals cracks up to .08 inches thick and reseals future hairline cracking. The product reduces chloride diffusion coefficient by 89% to 3.5 (107.5 square feet to 129 square feet per second), as well as reduces water permeability by 70% to 5.9 (32 feet to 39 feet per second) at 142.2 PSI. It also increases surface hardness from 6 to 8 on Moh’s scale and allows 84.1% moisture vapor permeability. Radcon Formula #7® reduces scaling in freeze-thaw environments by 89% at 50 cycles and is suitable for tanking applications (positive hydrostatic pressure), tested to 1,312 feet. This formula is non-toxic and has certified suitability for potable water.

Application: Basic Requirements
Radcon Formula #7® should be applied to a clean, dry, and dust-free surface that is a minimum of 28 days old. Any curing compounds should be degraded or removed before applying the product. Any materials that would deter penetration should be removed. Where there are segregation or voids, chip out and treat with Radcon Formula #7®, then finish with cementitious materials. Follow proper concrete practices such as necessary curing, compaction, and vibration. Concrete that is old or carbonated needs a supplementary treatment to reinstate free calcium. Do not apply Radcon Formula #7® where ambient temperatures are below 39℉ or above 95℉.

Locate any cracks and flood voids with the solution first, ensuring they are filled with the product. Apply the solution to the remaining area at a rate between 43 and 65 square feet per liter. When the surface becomes dry to the touch (usually two to six hours, depending on wind conditions and ambient temperature), flood-spray the treated areas with water. If the product is still wet after six hours, begin the first watering. On Day Two, 24 hours later, water again. On Day Three, 24 hours after that, water again. After the third watering, block drains and pond areas for a minimum of 12 hours to verify a waterproof seal has been achieved.
