RadonSeal® has been the leading concrete sealer for commercial and residential projects since late 1990's. It is a reactive internal sealer for poured concrete, concrete blocks, mortar, and other cementitious materials. RadonSeal penetrates deep into concrete (up to 6" depending on porosity), reacts, expands inside the pores, and cures as a silicate mineral.
