The recent heavy rain overwhelmed the drain in front of our garage, so I have made a second one to relieve it. ACO channel is nice and strong. So is the grating. The connecting shapes help so one can lay each lenght of channel smooth and even. The grating, however, is slightly wider than one driveway brick, or it is with ours, so you have to remove two bricks wide instead of one to make the trench for the drain, but it's not hard after you have dislodged the first brick. The channels cut cleanly allowing to a neat junction, although there is a lot of dust. I installed the drain during the weeks over Christmas and New Year so, obviously, I'm not a real builder. Having a good quality ACO product to begin with helped enormously, thank you.
