Water getting into your basement?

Liquid Rubber Foundation Sealant - Waterproof Leaky Basement

Why is it so difficult to figure out how to stop water from coming into your basement?

It's actually usually a fairly simple solution.

Read below to find out how Liquid Rubber Foundation Sealant can keep you dry

Water coming into your basement is generally a result of water pooling around your foundation. If you can keep most of the water away, waterproofing from the inside can work for you. It's always best to waterproof from the exterior but not always possible.

Ensure a clean, dry surface
If you have deep cracks, fill with a Crack Injection Kit
Bridge joints, cracks, seams etc., with Liquid Rubber Geo-Textile
Build up heavy coats to achieve required thickness
See Products Used below

Liquid Rubber Foundation Sealant can be painted over with standard wall paint
Ensure rain gutters have extensions taking water away from your home
Build grade/earth/dirt/drainage sloping away from your home
Weeping Tile can be installed to direct water away
Dust or dirt can cause loss of adhesion
Product stays soft, flexible and may have some tackiness
Apply next heavy coat when product is dry to touch and nothing is wet underneath. Tacky is ok
Use up all required material to ensure a long lasting membrane
Apply above 10C/50F
Remove painter's tape while coating is still wet

Coverage varies by product used. See Product Page for specific coverage of that product

Looks Good

I applied the LR where I needed it. It went on rather easy, wasn't to messy and the final job looks good. I did this about 3 weeks ago, so how well it will hold up, I can't say. But I have used other similar products and the are more dry texture once a couple of weeks have gone by, and a couple of years down the road they start cracking. LR looks more "rubbery" so far, and for now looks less prone to cracking, but only time will tell.

I was late in the season for application, only applied one coat. If I get some warmer weather I’ll apply the rest.

Liquid Rubber For Deck

I have been very impressed with the product, and the company. They have been very helpful in guiding my application. We received the product, and started applying in early October. Unfortunately, mother nature has not been cooperative, and we were only able to apply two coats to the deck, before the fall rains started. But, even with those two coats, our very large deck has not leaked a drop as far as I can see. Our garage is underneath, and with the ceiling exposed, I would notice any water. Therefore, I will wait until the spring to apply the final coats. Easy to apply, excellent directions! Five stars all the way, and I would purchase from this company at any time, and would recommend them highly!

Great customer service

Employee phoned me in response to an email sent, arranged an appropriate time for a phone call order. Kind and courteous. Prompt and patient. Looked up my previous order ensure I got identical products!
Great customer service

Liquid Rubber as a company to deal with.

Today I wanted to return a 5 gal pail of their foundation sealant, It was past the 90 days by a few days. The gentleman Tim on the phone was very accommodating. Very easy to return the product. Dropped off at their warehouse and was greeted by Trevor. As well another very accommodating individual and full of knowledge about basement wall issues. I must say my interaction with this company has been 100% positive. The product is either doing what it was designed to do or there has not been enough water moisture to test it yet. Either way my basement is dry. 5 stars for the company.

Easy to use

Will be hard to give a 100% honest review until spring to see if it holds up. It’s very simple to apply, recommend a brush not a roller. I got more product on myself then the wall when using a roller.

Great sealant

Applied several layers of sealant on exterior foundation wall. Worked like a charm and i highly recommend this product

Used for under the stairs damp area.

Product was easy to apply and sealed up the basement section perfectly.
It is a little bit sticky to the touch if it isn't painted, so I painted it and love it.
I was able to use the space under the stairs for storage without worrying about mold.
Great product and only time will tell if it keeps up.
