Trench Drain ideas?

[KPSquared]

I'm in the process of getting my garage ready for the floor and I have always intended on putting in a trench drain. I'm not sure if this is the best option, but I want something I can shovel the **** out of and something that will collect the water that runs off my cars.

My plan is to put it across the front (garage door side) of my garage with a drain hole in the center. It would be about 24 feet long and 10" wide with a steel grate on top.

Is there a secret to forming this up or is it better to try and get a pre-formed setup like this --> http://www.acousa.com/drain/slabdrain.htm

Any ideas or suggestions are appreciated. I would slope from the doors in and from the back toward the drain. I like the idea, but need to know if it is a sound one. I have a pic drawn up, but these work computers bring the **** so you'll have to use your imagination for now. . .

There are a few companies that sell a system similar to that. All of them are expensive. Those are designed to be placed on the prepped area and concrete up to the edge.

I have a feeling they cost a pretty penny. My plan at this point is to form it all up with wood. I just can't quite wrap my head around how I could do it with one pour. . . probably can't.

Form the outside, then pour the bottom of the trench later? That seems to be all I can come up with.

Purchase the preformed you will never regret it. I just had 30 feet of Zurn quoted and it was right at the 1K mark without the grates. Luckily I have grates from some trench drain that we tore out at the plant.

There are several ways out there to build a trench drain. They have pre-made drain assemblies (like you listed above) that you select where the outlet will be and they are pre-sloped . These typically end up with the best finished product that looks good and drains well without having any standing water in the trench.

You can also just get the top grate and angles (or shelf to hold the grate) and form your drain out of concrete. To use concrete you can hang the side forms and when the concrete is just getting firm enough you can pull the stakes and remove the sides. You can also just use foam for a block-out and then after the concrete is hard you can cut the foam out (you can also be not so PC and pour Gas on the foam and it will eat it up).

Good Luck

I'm currently building a post frame building for a shop, building and doors are to be completed in the next few days, if it stops raining!! This is a 39x54x14, with 3 overhead doors covering most of one eave side. I was talking with the concrete guy about doing a trench drain across the doors, about 4' in from the doors, and he said his preference was to form them, rather than the pre-fabricated. He said they would make it around 6-8 inches wide, so you can clean it out with a small shovel, rather than the 4" size that is more difficult to clean. I'm not much help, as far as how he plans on doing it, but that was what he recommended. The trench will slope all to one end, with the drain end being run out underground and tied into a tile line that cuts across my yard. (and before everyone freaks out about the drain line, it has already been approved by the building inspector. Drain to daylight, and they don't care if daylight is 1/2 mile away in a field waterway)

I bought the shovel ahead of time. . .planning to build the trench based on it's width.

Even if you don't know how, it's good to see someone else with the same plan. Talked to my concrete guy today and have a good idea of how to form it up.
