Waterproofing High-Humidity Basement
I have a 2000 square foot home with a finished basement and have started basement renovation of an existing space and need some advice about waterproofing to make sure I do it right. I had some water puddling in the corners, wall efferoscenct, fireplace brick, moisture on the concrete block walls, and basement humidity. My humidifier runs much of the day in the spring and summer and need to be emptied every couple of days.
I painted the interior of my walls and one foot of my floor with Hydro-Seal 75 waterprrofing Epoxy and it did not solve the problem. After painting, some of the painted flaked off the walls and the floor started breaking up crumbing floor within the the 12″ and efferoscent continued.
Next, after reading the site I replaced my gutters and made sure they drained out 10′ from the house. The water puddling went away and the floor seems to have stopped crumbling, But, still getting moisture evident by the floor efferoscent expecially after spring rains. I have talked to basment waterproofers and they are all over the map and seem to have very different opinions or maybe just want a sale.
Waterproofer #1 – Do Nothing
Do nothing since the problem is not bad enough. Recommended exterior grading and said don’t worry about it waterproofing. Also invest in a commercial dehumidifier and patch floor.
Waterproofer #2 – Interior Drain ($6000 – $7,500)
Told me a interior would fix the issue with a sumpump. Even said this method should fix my efferoscent & humidity would go away.
Waterproofer #3 – Exterior Drain ($10,000 – $15,000)
Said the exterior is the best and only way to fix the issue with a drain. Told me my home is old built in the mid 70’s and probably has not concrete tar or existing drain. Needs to install drain on two walls to solve issue.
What would you recommed on how to approach this since I do not have standing water? Your opinons are grealy appriciated.
