Interior Concrete Waterproofing: Protect Your Concrete Against Water Damage

Moisture is a major enemy of concrete. It can weaken concrete, make it crack and in general cause deterioration of any concrete structure. Moisture can also cause staining and fungus that is nearly impossible to remove. Interior concrete waterproofing can help prevent moisture damage of this type.

Before you apply any type of interior concrete waterproofing you should first make sure any leakage or drainage problems are corrected. Just because you apply waterproofing doesn’t mean water won’t occur in the area. If landscape drainage problems or leaks aren’t fixed, you’ll still have water pooling on the treated concrete.

Interior concrete waterproofing is a sealing method that can be used on poured concrete, concrete blocks and even on stone foundations. Interior concrete waterproofing can be used on new and old concrete alike. For the best protection you should seal concrete right after the curing stage.

The sealant you use should protect against water, water vapor, and radon. To waterproof properly you may have to apply more than one coat of sealant, usually at least two. Read the manufacturer directions carefully before applying your brand of sealer.

Make sure to thoroughly clean and dry all concrete before you apply any interior concrete waterproofing. For existing concrete surfaces such as in a basement, all old paint or adhesive that might have been used on the floor must be removed before it can be waterproofed. The areas to be treated should be as clean as possible and free of any mold or mildew.

If you want to waterproof concrete foundation walls they must be cured for about a month. Sealants will keep cracks, holes or defects in concrete foundation walls from receiving moisture as well. For best water protection, it is usually recommended to seal both sides of the wall, using an exterior coating on the outside.
