Garage Floor Water Drainage??

Question Icon

I have a 7 year old detached garage. I have insulated it & have been heating it for the past 5 years. The garage floor has the correct slope (higher in rear of garage slopping towards the front of garage). I live in Edmonton so the snow melt in the garage is always a challenge to keep the water from pooling by the garage doors & freezing them shut. I am considering cutting the slab and installing a trench and catch basin system. This way I will control the water run off. The catch basins won't drain anywhere. I will simply scoop out the water if they fill up.

Any thoughts on doing this? Or is there a better way?

Hi Nathan

Remi here from Remi's Handyman Services - RENO TEAM.

We would suggest the easiest if this garage is heated, would be to install a drain with a sump pump, cutting out the trench and installing it to discharge away from the garage; in some cases a tray under the vehicle can catch the water that melted and it will evaporate sooner or later.

Thanks

I appreciate your suggestion Remi, but as this is a garage where vehicles are parked & occasionally worked on, I don't want to just discharge water that may be contaminated with grease or oil out onto my yard or the back lane. With a catch basin I will be able to lift out the captured water & dispose of it properly. I have thought about the vehicle mats but want a more permanent fix than that.

I would install a pump on a float lever inside the catch basin u can do this pretty simply yourself but it's very important you make any electrical water proof

Hi Nathan. It seems as though you've figured out a good solution yourself. I'm not exactly sure what the rules and regulations are where you live but disposing of the liquid properly is a great idea. I also like the sump pump idea as well. That way if the drain does fill up it will keep it from overflowing. Maybe get yourself a plastic barrel and create a stand for it so it's about 5 feet off the ground. Then when it starts to get full you can siphon feed it into another barrel or containers in your truck and dispose of the fluids properly. There are many ways to do this but without looking at it and discussing it were all just throwing stuff out there. Best of luck Nathan.

Installing a Catch basin would help the problem.

That would be your only solution. The water will pool infront of the garage door no matter what. I cant think of any another solution. My thoughts on doing this would be , to install a catch basin.

When I built my 24 x 24 detached garage in Edmonton I sloped the floor to the center and embedded a plastic bucket to act as a sump. I empty out the water manually as you are planning and it works OK I also ran a 2" PVC pipe underground which originally led to a weeping tile pipe. When I later dug up the yard for a second time (for a sunroom addition) I didn't take the time to reinstall the weeping tile pipe however it did work for the time I had it.
