Our most reliable sump pump system, the TripleSafe™ Sump Pump System, provides three levels of protection for your basement and your peace of mind.

For normal functioning, the TripleSafe™ has a powerful, cast-iron Zoeller® ⅓ horsepower sump pump set at the lowest level. For heavy volumes of water or in case of primary pump failure, a second, more powerful Zoeller® ½ hp pump set a bit higher in the liner will take over.

In case of a power outage, our UltraSump® battery backup sump pump, set at the highest level, will pump 11,500 gallons or more on a fully charged battery!

Hi! I'd like to get a quote about fixing a crack and leveling the cement for my basement. (I live in Ottawa and my house is around 15 years old, also my basement is about 270 sq ft) The context is I plan to put on new floors for my basement, but after getting rid of the old carpet I see there is a narrow crack (less than 1/8 inch) on the cement, and also it's a bit uneven on some areas (the middle is a bit higher than the edges). Ideally I would like to fix the crack and level the cement to make it even before putting on the floor. If possible can I get a quote on this? Let me know if other information is needed. Thanks!

I have a sump pump that runs quite frequently, even when there is no rain. I would like to determine, where it discharges to. Perhaps it discharges too close to the home. Thank you.

I have a 15 year old house and I hear cracking sounds occasionally at night. I found cracks in the basement floor and foundation wall on the outside. There is sunken ground around a window well on both sides and along the foundation wall with the crack in it. The basement floor has two cracks, one crack is about 2mm wide and a few feet long, the other is about 2mm wide and many feet long from one wall to the outside wall. The outside foundation wall crack is about 2-3mm wide above ground, and may go below ground I would like to have an estimate for a foundation settlement assessments and advice on what needs to be done, and a quote on fixing the issues such as the cracks, waterproofing and possibly weeping tile replacement on one side.
