Drylok waterproofing on concrete walls?

Question

I live in a very leaky house in Taiwan. (most houses here leak).

In order to at least ensure that my bedroom is dry, I have decided to use Drylok on the worst hit walls.

I have stripped one concrete wall down to where it's mainly concrete. There are however still bits of the thin cement layer used to make the wall straight, and here or there some thin bits of concrete paint.

If I after using UGL etch on the wall and plaster the cracks over use drylok, will it last?

Answer 1

I used it on a slump block wall in a subterranean garage at my townhome rentals. We put on three really good, thick coats when the wall was completely dried. I lasted a good 5 years and did seal out the water that was coming through the wall. We gave it another coat after 5 years more because it was starting to look dirty (car exhaust) more than because it started to leak again.

Answer 2

Drylock and the such is basically a band aid. It may hold for a while, 6 months to a year. The key to keeping water out of the house is to catch it using roof gutter, and then drain it away from the house. Make sure the exterior grading of soil is away from the house. Water getting into the concrete will also cause it to fail and start cracking at some point.

Answer 3

It will probably work for awhile, the only way to fix it for good is to use a combination of exterior membrane system and drainage. Water finds a way to get through every time.

Answer 4

drylock is good but also line roof of house with tin 4 further waterproofing. slant tin down so rain will just drain off and away from house.

Answer 5

Aqua lok is the way to go after u etch...u can find it at sherwin williams. they use this material in pools to prevent leakage...good luck

Answer 6

i dunno, we washed down the walls, then used drylock and it worked good for us, be sure and scrub it in good. follow direction. that always seems to help. ours is still there even after a good five or six years.
