Topic tags/keywords: basement question floors insulation paint

Hello all

I have a dampness issue in part of my basement. I just ripped out about 2 tons of drywall and what used to be a framed wall (vacuumed up the footers and about 2 feet up the studs). Whoever built this room did a half assed job at it. They did not use treated lumber and no plastic or insulation. The other areas of the basement that have plastic and insulation are fine. Here is my question….Now that I have ripped to the concrete how do I go about sealing that area from moisture?? Do I use dry-lok paint? Does that stuff even work? should I put in drain tile? Are there other options available for me besides digging up around the house and hitting the foundation with a hot mop?? I want to do this so it will last but I do not have thousands of dollars sitting around collecting dust. A little more info on the situation….walls are cinder block (hollow) and I am planning on installing a whole house de-humidifier, no central air so no cold air return (actually no duct work in the house as I have electric heat). I will be installing a pergo laminate floating floor with a DRIcore subfloor. Thank you for your time and suggestions.

Dry-Loc works great for like sweating type of moisture leakage. If theres more than sweating for leakage that would indicate a drainage problem requiring a different tactic. Which could be as simple as trenching around the house or problem wall about 3-4” and laying down a bed of pea gravel and then some drainage pipe to aid in water run off and backfill all but about 12” then finish back filling with topsoil. Hope your problem has already been taken care of looking at how long ago you posted this.

Greg, is on target with his response. I had a similar issue with my block foundation walls. The bottom line is that if the water is coming through the blocks from the outside then one method of relieving the pressure is to drill holes in through the blocks and channel the water to a sump pump, as Greg is describing. I did this in combination with Dry-locing the walls and it pretty much solved the moisture issue. It does not eliminate the moisture from the house but it does control it.
