How to Cut a Drainage Channel into a Concrete Slab

In todays video we show you how to fix drainage issues on a concrete slab. We try two different techniques in this video. We first tried putting multiple saw cuts in the slab, it worked okay. Then, DeWalt sent us their channel grinder only on the European market to use for this video which worked excellent. We also announce the KEEN boot giveaway winner!

David the main reason I enjoy your videos is you are a worker yourself. You have a problem solving mentality and lets roll motivation! I really enjoy your work and dialog! Excellent I have learned so much over the last 5 months! Thanks please keep them coming!

That Dewalt grinder did an awesome The vacuum also did a perfect job collecting all the dust!! Great work!!!

Its always satisfying redirecting the rain, and solving the problem Nice work!

European here. We use the small prybar(yes that's not a chisel) to break off chunks then rotohammer with a sds chisel the rest out. I would've used a 230 mm large grinder to cut a deeper wider channel and put a grate over it like an Italian drain and seal the bottom of it. I'm an electrician and not a concrete guy but from my point a lot more could've gotten done with a lot less fussing.

Any job, big or small. Odell and sons do it all!

@Odell is so high speed he's got tools that are even out yet.

Way to go David, when conditions on the ground changed you switched tactics and used the Dewalt! Concrete work is not easy and you get after it!!! Thank you for the videos!

I just came here for one specific tip... And stayed to watch the next part. This is very well done, and you are very easy to listen to.

great video, wish i saw this tool earlier, I had a similar problem with an interior floor to a center trench drain..What i did was made a pitched surface using wood and shims to run the saw on, and made a pitched or sloped cut toward the drain.i then used a liquid sealer in the cut to try to avoid water penetration into the slab. seems to be working ok.i wish they made a thicker blade, ended up using 2 blades together.this was using a 7 inch blade with a circular saw and water.

Just poured a deck and realized we forgot to run a 1/2 water line. This is exactly what I needed. Thanks for the upload.

What a ton of work with expensive single-purpose equipment for quite a marginal result: the channel is barely 3mm deep after adding that liner material. How about running two cuts from a wet saw : a vertical and a 45degree mitred cut and allow them to meet say an inch into the concrete? Now you have a deeper channel and the chiseling may be minimal.

Another fine example of ingenuity, keep up the great work.

The blades are meant to be used together to create multiple cuts, would have saved you guys a lot of heartache. That tool looks amazing, wish we could get it here, I know there are others, but the cordless version looks like it would be very useful. I've got to cut a chase in my garage, we switched entry point and water drips from car & runs down to the now wall, you gave me great inspiration, great video!!!

[blivioniox]

Nice. I have to do almost the same exact thing for my garage. This gave me a bunch of good ideas.

[Shumi-krtc]

You always have such interesting videos. Very cool that Dewalt work with you to get you the saw that wasnt yet on sale.

[Mountain_Goat]

So glad I watched this. I was about to just use an angle grinder but this video has reminded me that I already have a wall chaser from when I was doing my electrics and I am pretty sure that's what the Dewalt tool was? And I have a chisel that fits the width of the cut which is perfect I have a super similar problem but on a smaller scale. Alleyway with a crossfall towards the garage meaning it just pools against the wall. Hoping I can just channel through the path and collect it at the lowest points and then send it back the other way. . . . fingers crossed!

[bsmanohar]

Thanks for this. I have a similar situation and good to know a tool exists. Btw why not insert an aluminum channel in it for a clean look?

Owners shouldve asked for a 8” wide channel and a 8” wide grate the length of the pad, exiting on the dirt side. A lot of garage opening have them, when the driveway slopes down to the door

[triciaeverett]

Real simple clever solution & probably saved the homeowner money lots of times those grates end up all loose n broken anyway
