This basement sealer is ideal for anyone looking to mitigate concrete dust in their basement, or use it in combination with a separate waterproof sealer for maximum moisture protection.

Also, know what the sealer will do on the floor. Does it penetrate the surface and protect the concrete from within? Does it penetrate a little bit and sit on top to act as a sacrificial coating?

For towns with aging concrete water tanks, the dilemma is usually the same: repair or build new. In repair, re-waterproofing can buy another decade or two so they can budget for the new expense.
