RadonSeal® Concrete Sealer Limited Lifetime Money-Back Guarantee

RadonSeal Standard/Plus seals clean and sound concrete permanently against water and radon gas, provided it is applied in accordance with Application Instructions.

Performance Guarantees

We provide the following performance guarantees on do-it-yourself application by homeowners to concrete in their basement or slab-on-grade homes.

Waterproofing Guarantee: RadonSeal seals poured concrete and heavyweight concrete blocks against wicking water, positive as well as negative side water pressure. RadonSeal does not seal cracks, gaps, fissures, seams, or joints where water can easily leak through.

Radon Reduction Guarantee: RadonSeal® Penetrating Concrete Sealer must be applied to all basement walls and the floor, or to the entire slab-on-grade foundation slab. RadonSeal will reduce and/or keep the indoor radon level below the Action Limit of 4 pCi/L. However, you must also seal or caulk all cracks, joints, protrusions, and any openings in the basement walls or slab. The guarantee does not apply to basements with stone foundations, protruding rocks, dirt floor, attached crawlspace, or radon carried in by water from a private well. If your radon level exceeds 20 pCi/L, you must phone us first for consultation. Let RadonSeal cure for at least 30 days before testing.

Warranty Period: Lifetime of the concrete.

RadonSeal® Exclusions and Limitations

If the concrete repeatedly seeps water, you must phone us first for consultation. The concrete must not be leached out or internally silted up due to years of extensive water seepage resulting in heavy amounts of efflorescence.

Poured Concrete – The concrete must be at least 28 days old and at least 3+ inches in thickness. RadonSeal is not guaranteed to seal integrally colored concrete, stamped concrete, and fiber reinforced concrete (use LastiSeal or Ion-Bond Armor sealers instead). The penetration of RadonSeal into the concrete is not guaranteed. Machine-troweled, polished, or overly smooth finished concrete surfaces may require acid etching (1pH etcher) or mechanical-abrasion to alleviate surface tension.

Concrete Blocks – RadonSeal┬« Plus seals heavyweight-concrete blocks. RadonSeal does not seal concrete with low cement content like lightweight CMUs, popcorn or splitface blocks (use LastiSeal or Ion-Bond Armor). Please take the time to read, How To Seal Concrete Blocks

Cinder Blocks – While RadonSeal® Plus successfully seals most block foundations and walls, there is a possibility it may not suffice for waterproofing cinder blocks. Why? Since RadonSeal works by reacting with cement it simply cannot be guaranteed to seal all cinder blocks (cinder blocks contain fly ash, less cement).

Using RadonSeal® with Ion-Bond Armor to seal cinder blocks has proved foolproof for many a homeowner and contractor. Ion-Bond Armor is often applied to concrete first sealed with RadonSeal to provide the tightest possible seal against water vapor and gases. The combination of the two is needed for sealing more porous blocks or cinder blocks in basements. Extensively leached-out and older cinder blocks (+20 years) may require additional steps to properly fill and seal the enlarged pores. Please take the time to read, How To Seal Cinder Blocks

Refund: If you are not satisfied with the results, you must phone us first for consultation and email requested photographs of the basement or slab. In case you subsequently decide to hire a professional contractor to install a de-watering/waterproofing system or a fan-based mitigation system, mail us a copy of the tests and paid contract for a full refund of the price paid for RadonSeal (excluding shipping) but not exceeding the cost of the contract.

This guarantee is valid for product purchased directly from us after March 18, 2010.
