When looking for a sealer to combat water, especially in a basement, it is imperative that you figure out where the water is coming from. Is water leaking through a large crack in the floor or through the cold seams? Or is water seeping through the floor or the walls? If the water is coming up through a crack or cold seam you need to seal it with an injectable epoxy or polyurethane solution that is able to combat large amounts of water pressure. If you are preventatively sealing a poured concrete foundation slab you'll want to use Lithi-Tek 9500.
Lithi-Tek 9500 is a unique and proprietary formula that was formulated using molecular nanotechnology. This is important because nanoparticles are stronger, smaller and lighter to effectively penetrate deeper and chemically react more evenly. This allows the Lithi-Tek 9500 to travel through all voids, pores and tracts, chemically bonding to the concrete. The Lithi-Tek 9500 utilizes the smallest atomic structures possible, one thousand times smaller than the wavelengths of light, resulting from the manipulation of single nanoparticle molecules in finely controlled ways. These improved systems control penetration and prevent/remediate water, mold, mildew, efflorescence, radon, hydrostatic pressure and water vapor transmission. You will be hardpressed to find another sealer that performs so effectively, water will never again be an issue in your basement. If you are not using Lithi-Tek 9500 you are not properly sealing and permanently waterproofing your basement.
However if you are sealing a poured concrete foundation that has already expereinced some seepage or moisture it is best to use a two step process. First use the Lithi-Tek 4500 as a primer and then use the Siloxa-Tek 8500 as a top coat. The combination of the two products will combat mositure intrusion, organic growth and efflorescence. If water is coming in through concrete blocks or cinderblocks then you need to use Siloxa-Tek 8500 as a stand alone product. Because of the porosity of the concrete blocks it will provide the most effective seal.
