Hello. I'm in the process of fixing up my garage workshop. Along with new doors and heat, I need to install a channel or trench drain between garage and driveway to stop water from coming under the garage door. Its not a whole lot,, and it always flows back out but it is not ideal.

I've ordered Source1 drain channels and 2 quad connectors from Amazon. It seems pretty straight forward. Cut the asphalt out about 12", dig and place the plastic channels, then back fill with concrete. Easy peasy!

Has anyone used this product or done this job?
I have used my circ saw with diamond blade and water to cut a slot in asphalt, but this will be quite a bit more and I'm thinking about renting a larger saw from home depot to make the cuts.
I have a mixer that we've used over the years for many projects so that should be ok. Colder weather pour is new to me, but I think I can cover it well enough. Air Temps just hitting 30s around here.
Any advice?

 

I've seen them but never installed. I would agree with the need for something a little bigger to cut the asphalt. One time I rented an saw to trim a natural stone step, it was a chain saw cutter with a large abrasive blade, about 18" in dia. Cut through that step like butter!

 

Depending on what you find underneath your driveway you may need to over dig the trench. Then back fill with layers of compacted crushed stone. This will provide a solid foundation for the drain. When driving vehicles into the garage it will be supporting the weight so you don't want your drain to get pushed deeper into the ground.

Generally I would say it is the wrong season for pouring concrete in the Chicago area. You say your temps are "hitting 30". I assume that is the high temp and not the average or lows. So, you are actually dealing with colder temps than 30. And don't forget. Concrete takes about a month to fully harden. Longer in colder temperatures so to get a strong pour you may have to keep the area warm/heated for longer than you want.

 

Winter has been a lamb so far, 30s have been the lows! Supposed to turn into a bear next week.
Considering that water should be frozen beyond this point, and therefore not flowing into the garage, I will likely hold off on this part of the project til next spring. Unless we have warmer temps... crazier things have happened.

 

Its done! We had 40+ weather for the 4 day new years weekend , I decided on Friday morning to go for it. Rented the saw, cut it out and dug out the trench on Friday. Fitted the channel on Friday, which required more digging. Rented a big 9cf mixer and picked up (66) 60lb bags of concrete.
Did the pour on Sunday. 50 bags in 9 hours, single handed.
I'm trying to figure out picture posting...

 

50 bags yourself... you-da-man! I did half that recently and I felt like an old man for days afterwards.

 

I was glad to go back to work! Lol. Definitely feeling worn out.
its looking good a few days later. Not the best finish but thats ok. No more water in the garage! I need to remove the remaining tape used to cover the top and fill in a little dirt on the ends.
