There are a few reasons why you want to seize the moment and seal your basement before winter. If you live in an area where it snows in the winter it is especially imperative that you continue reading this article. Spring brings melting, flooding and an all around wet season. The snow is melting and the ground is wet and basements are prone to flooding, and water damage.
The first step you need to take is to assess whether or not you have had previous moisture issues in your basement. Think back to last spring, have you ever sealed your basement before and is the sealer you used working? Is it bubbling or peeling or are you still experiencing moisture issues? If so this is a sign that you a.) did not use a high quality industrial grade sealer or b.) the water is coming in through some unsound cracks in your basement.
If you used a previous sealer you need to make sure you etch the floor to remove the previous sealer. Next you need to fix all basement cracks. Use a crack filler or crack sealer to make sure that there are no possible outlets for water to enter the basement. You are then going to want to seal your basement with a high quality concrete sealer. If you basement foundation was built with concrete blocks or cinderblocks you need to use a silane/siloxane blended sealer like Siloxa-Tek 8500. The Siloxa-Tek 8500 works best on concrete blocks because of the porous nature of the blocks and the larger molecular size of the silane/siloxane particles.
If your basement foundation was poured and you are preventatively sealing (meaning you have never has any moisture or seepage issues) your best option would be the Lithi-Tek 9500. The Lithi-Tek 9500 is a densifier, waterproofer and sealer all in one. This product will help prevent all future moisture issues by chemically reacting with the concrete to form calcium silicate hydrate inside of the concrete and sealing the surface all-in-one.
If your basement foundation was poured and you have experienced moisture or seepage issues in the past your best option would be the Lithi-Tek 4500 product followed by the Siloxa-Tek 8500 (applied 7 days after the Lithi-Tek 4500). The combination of the two products provides unsurpassed protection to keep water from seeping through the concrete causing damage.
