Product Description

Complete crack injection kits for do-it-yourself application by homeowners. All you need is a standard caulking gun and a crack in your poured concrete wall!

The No.1 Crack Injection Kit for homeowners for over 25 years.

Suitable for both hairline cracks and wide cracks (up to 1/2″). Can seal up to 10 feet of cracks in poured concrete.

RadonSeal standard DIY crack repair kit uses polyurethane foam that forcefully expands to fill the full depth and length of the crack. Polyurethane injection foam adheres to wet or damp surfaces inside the crack — there is no need to wait until the crack dries out.

If structural strength is needed, use our Epoxy Crack Injection Kit.

If appearance of the wall is important, use the Easy-Peel Injection Kit with a special surface sealer that can be easily removed.
