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!

We have a pair of existing sumps with two check valves merging into a single outlet pipe. I replaced the main sump a couple years ago (proactive, but getting older) and have noticed we are not getting the run time out of the backup pump when the power is out that we require. I have two deep cycle batteries (only one connected at a time) and each one drains in 4-6hrs. Since one of the batteries has only seen light use and is less than 3 years old. I'm assuming the problem is an aging pump because my neighbour gets 5+ days on a single charge from a similarly spec'd battery. I'm interested in the following changes: - Replacement of the backup pump and BMS - Adding stop valves above the check valves to simplify maintenance

Occasional small amount of water in the basement (2-3 times in 6 yrs). In the process of finishing the basement and would like it fixed, so no future problems would arise.

Hi there, I have a number of cracks in my basement foundation and one going up a foundation wall that I would like to have checked, possibly fixed. I can tell based on other areas of the house that there is a lot of shifting/settling happening and want to ensure there are no issues with my foundation. Thanks

Hello. Just bought a radon detector and it is reading about 8.04 pCi/l in the basement. I am testing in other areas of the basement but would like you guys to come in and give me a more accurate reading and possible mitigation method/estimate. Appreciate you getting back to me by email please.

Hi there, We recently moved into our 1964 brick home and I noticed two cracks on the back of the house, one is between the bricks and one on the concrete foundation. I was hoping to get these looked at to see what we're working with. Thanks, Kim

We are under construction building a walkway and when it rained we had serious water in the basement.We have a digger if needed
Project Location: Nepean, ON
High-normal radon level of 178.
Project Location: Nepean, ON
We have owned this home for 11 years. 3/4 of the basement is finished with raised subfloor. When there is heavy rain we have water pooling in the unfinished furnace room where there is a drain. It appears to be coming up from the drain and from a 'money safe' cavity that the former owner installed in the floor. We don't use this safe. There is often water pooled on the safe even when rest of floor is dry. We have ignored this for years. We don't plan to sell the house for many years however I want to resolve this situation now so that there are no 'issues' when we go to sell. If possible I would like the work quoted ASAP and the actual work done this fall if possible. If that is not possible then we would look at spring. I am retired and can meet anytime 24/7. Thanks!!

Small puddles after the last heavy rainfall. It has happened a few times before. One hole was suspected and taken care of. But now this. I will appreciate it if you can tell me how you can help. Thanks.
Project Location: Nepean, ON
Downspout drainage is not working properly. This led to water entering a basement window well and flooding the basement.
