Job Stories From Ottawa, ON
BluesFest Festival House and School of Music in Ottawa West end

The Foundation Guys were called in to waterproof the exterior walls at Bluesfest Festival House and school of music. The Rub-R-Wall membrane and Geo-Wrap drainage system was the top choice for the project. They had water in the basement of the building and did not want it to happen again. They decided to go with a high end waterproofing membrane with a life time warranty. They chose to rubberize the foundation. Now they have enjoyed a dry basement where the children can learn in a healthy environment in the Bluesfest School of Music.

Looking to waterproof new ICF foundation.

I have two spots where water is entering the unfinished part of my basement. Cracks are on opposite sides of the house, about 6 inches off the floor and approximately 5 feet underground.

I own a 80 year old house. The floor had heaved when i purchased it 20 years ago. Would like to see about getting it leveled out to make it more useable.

Townhouse on grade (no basement) slab has sunk up to 2+". We completely gutted down to studs and are now rebuilding and want to ensure the slab won't sink anymore (fill the air space void) and/or restore to a somewhat level situation. There is one wall and a post on the slab plus a closet. Size of the area is a hallway with stairs (stairs are floating attached to the side wall) and a back room that is 10'x21'. There is plumbing and a main sewer line under the slab.

Vicinity of Wilshire Ave in Ottawa
Our home has an addition from the 1960's with a block foundation that has a horizontal crack and slightly bowed. Mostly likely caused by a tree that used to be adjacent to the wall. Would like to look into carbon fibre stitching. Thanks
Vicinity of Harvard Ave in Ottawa
Water is getting into the finished basement mostly through the garage which is at the same level as the basement; but also on the south side of the foundation wall. Musty and want to ensure healthy air quality etc.
Vicinity of Twin Falls Place in Ottawa
We have a crack. No water issues but not sure if it requires structural support or just filled. It runs into the corner of our garage. We have a smaller crack on the other side of the house too but again, no water issues. We don't think either crack runs into basement. The one crack though is a decent size and the concrete in the garage is pulled out too. Would like a structural engineer/expert to look at it.

Hi. I have an issue in my home with Iron Ocre (iron batteria). It's clogging my two sumps. :( Would like some ideas on how to properly deal with it. Thanks!

Water seepage in basement under flooring, source unknown.
Vicinity of Gavin Street in Ottawa
I have had water leaks in my foundation which I have had fixed. Several of my neighbours have had a lot of water issues and have had sump pumps installed. I am aware that there is often water sitting by my foundation and there is always a musty smell in my basement. I am wondering if this would be alleviated if I were to install a sump pump.
Vicinity of Buell Street in Ottawa
Hi -- I have a (recently purchased) house with an extension that seems to have developed some foundation issues during last week's storm. The main house is over 100 years old and the extension goes back to at least 1950. The only issues we have at this point are in the extension. After last week's storms, we had lots of water in the basement of this section that has since dried up, but a corner of the foundation seems to have developed some damage as well. It looks like there used to be a sump pump in this space but it's definitely not there any more as the pit is clearly filled in. The space is unfinished so the foundation is exposed. Happy to send you a photo if that helps, too. I'm looking for information on what the issue is, how we can fix it for now, and of course, a long term solution so it doesn't happen again. Can you help? Thanks! -robyn
