Your Home faces Water Damage

1. Ontario receives a good amount of rain and when you add on melting snow flash floods are a serious concern.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

    Mel and Janet D. of Dunnville, ON

    Customer Testimonial

              This whole experience was positive. I dropped in at a neighbor's home and saw the work, spoke with Alfredo, telephoned for a salesman to come. Office staff always helpful and patient. If all crews and staff are as good as the ones we dealt with, you will soon be, if not already, number one in basement waterproofing. Today and last night we had 5 inches of rain and the basement and crawlspace remained dry! Wonderful! We should have done this sooner! We have and will continue to recommend this company to all our friends and neighbors.

    I was waiting for a large rainfall to test out my new basement system, which finally we received on May 31st. I am happy to report the basement has remained dry. I was a bit nervous due to the fact in the past even a light rainfall would result in water in the basement area. Thank you for correcting this problem!!

    No one has been able to inform us as to the original problem that led to OMNI installing a basement system. That is a piece of information I would really like to have.

Project Location: Riverdale Road, Beaverton, ON L0K 1A0

Comment: Water coming in our basement at the floor.

Project Location: Station Road, Smiths Falls, ON K7A 4S4

Comment: I have 2 sump holes, and 3 pumps. The water (I believe due to hydrostatic pressure) is breaching the floor by the foundation. I have had all the cracks in the floor filled in past years. The exterior weeping is working well, and flows to the 1st sump hole. The second sump hole has an equalizer connection to the 1st hole when it gets higher, as well as holes to permit water from the gravel under the floor slab to flow and evacuate. The sump holes have not breached, but I do have 1/4" of water flowing on 3/4 of my basement floor due to flowing through the space between the foundation and the floor. Is it possible to seal or fix the problem? I would be interested in getting an estimate. Thank you
