View Full Version : French Drains

We do some drain tile work(mostly for ballfields) have started using 6&quot; hard pipe with holes(can be jetted out for cleaning). We also use the spun fabric lining the trench, filled with a 3/4&quot; washed gravel. I know the hard pipe is more money per foot but I make it up with higher prices ($20-35 per foot). New toy just in laser control for our Kabota mini excavator should make installs like this faster.<p>----------<br>paul<br>

Paul,<p>How wide and deep is a trench of that price?<br>Is the pipe that you use flexible?<p>----------<br>Lanelle<br>

Lanelle,<br>The trench is 12&quot; to 18&quot; wide depending on the application, for ballfields along base lines, we use the 18&quot; wide trench, for other areas we use 12&quot; wide trench. The pipe we us is a PVC called SDR-35 perferated it needs no glue for joints as they have rubber seal type joints. depth of the pipe is a minimum of 2' and sometimes we go as deep as four feet. the pipe usally ends in a storm water drain. <p>----------<br>paul<br>

Paul - The same excavators I use (I've referred to them before) put the laser on thier 325 Cat last Spring. Charlie was dead on without it. Now, he flies. I have a laborer on with them all winter doing catch basin and re-inforced concrete pipe installation. Speaking of drainage, last week we dug out a small backyard and employed a geo-textile fabric with some 1 1/4&quot; stone to create an envelope. We will put the gutters/downspouts into the envelope and then filter fabric the area for loam and seed. Before this, it was like a tar pit in the back yard. We took some digital pics, and it has been quite effective. Next project is draining the two acres out behind the shop. My brother thinks we can handle it with a big envelope type drain leading to the pond, with pipe for the section where the road will be. I'll try take some pictures. BTW, we use the SDR-35 for drainage projects a lot. 4&quot; SDR-35 works well for Sanitary Sewer lines too. I once broke an 8&quot; ceramic tile forced main (unmarked) behind a hotel. :o We used SDR35 for the repair, and it worked like a charm. The gaskets combined with a couple of gigantic ferncos gave us the slide room necessary to make the splice. <p>----------<br>Phil Grande - Soundview Landscape Supply - http://members.aol.com/slsnursery<br>Ivy League Landscaping - http://members.aol.com/scagrider

Hey SLS,<p>That envelope technique is interesting. What were the dimensions of the envelope on that backyard project?

03-06-2000, 06:29 PM
We have done three soccer fieldssome what like that we would strip off all the topsoil, excavate 12&quot; deep, place a layer of fabric then 4&quot;-6&quot; of gravel installing 4&quot; pipe, in rows spaced 20' apart, then covered with fabric and 12&quot; of topsoil then seeded.<br>the pipe drains the field and a pump irragates the fields thru the same pipe.<p>----------<br>paul<br>

The dimensions of the yard were about 30x40. Its one house in from the Long Island Sound, next to an asphalt driveway that is pitched to sheet water down to the beach/rock area. Our envelope is set up like Paul's about 12&quot; deep with 4-6&quot; big clean stone, with the low side dumping out onto the asphalt. It would have been nice to tie into the storm sewers, but they're not available on this street, and unfortunately most people tie into the sanitary lines, creating problems. I didn't want to get involved with that sort of deal. The digital pictures came out nice. I'm going to try to post them on one of my pages.<p>----------<br>Phil Grande - Soundview Landscape Supply - http://members.aol.com/slsnursery<br>Ivy League Landscaping - http://members.aol.com/scagrider

Well - we received about 2&quot; of rain on Sunday, and the drain worked well. It was pumping water out and has dried out nicely. Maybe I'll even get to grow some lawn on it. This technique works, but don't cheat on the amount of stone.<p>----------<br>Phil Grande - Soundview Landscape Supply - http://members.aol.com/slsnursery<br>Ivy League Landscaping - http://members.aol.com/scagrider

Phil, <br>Should be able to handle alot more water than 2&quot; with 1% pitch it should handle a 4 inch rain fall and be dry in 24 hrs. The soccer fields that we did will handle 10&quot; of rain in 24 hours with out turning the pumps on. Now if we could just find more of this work :). have you tried the new case skid steers yet the xt95 might be somthing that might work for you, I too would like an IT28 but 135K is kinda high (plus lowboy)<p>----------<br>paul<br>

Paul - I've run the 95xt, and liked it. We have a Case dealer about 5-8 minutes from the shop, so I tend to lean towards those products. Since we have two divisions, the supply yard would benefit most from the big loader. I wouldn't really expect to take it onto jobs at this point. If we get another skid steer, it would be hard to leave one in the yard. I am considering a used machine and definitely not into spending 130K. The Case dealer has some Samsung Loaders that match up in size to the IT28. They have mostly common parts - Cummins motor, Clark Transmission, etc. So, I might look at this type of purchase as a step up to that type of machine, and worry about brand later. <p>----------<br>Phil Grande - Soundview Landscape Supply - http://members.aol.com/slsnursery<br>Ivy League Landscaping - http://members.aol.com/scagrider
