I ask because I know we have all sorts of folks here on badweb... Just got my driveway paved; looks awesome! But, we had some armageddon-level rains last night and I can see where erosion could be a problem. They graded about 6" on either side, that didn't get paved. The rain last night washed out a lot of that grading, and has already gotten a couple inches back under the blacktop. I'm going to backfill this weekend - hand and shovel work, nothing major (and I can always use the exercise). Any tips to keeping it in place while grass grows? I'm going to mix in the fastest-growing seed I can find as I fill, but I don't want it all to end up at the bottom of the hill the next time it rains. | ||

Netting, straw (hay), and hope the weather gods are with you. You can get grass seed sprayed on, and the medium they use acts to hold stuff in place somewhat, and holds moisture well to help the seeds start ASAP. I don't know if it's economical for smaller areas, though. | ||

Backfill under the driveway with something that won't settle, like decomposed granite. Sometimes you can get what they call 'road bed' at rock/mulch places. It packs easily, and tends to stay put. Have you called the paving company? They may offer a solution. They may even fix it for you since it was just poured. | ||

Riprap is good for concentrated flow paths provided you don't want to use the area for anything else. Your best solution generally is to re-establish permanent vegetation. If you can dodge any more big rain events for a couple of weeks, I'd just use topsoil, seed (or sod, even better), and maybe some kind of mulch (straw, shredded newsprint stuff) to keep the seed in place for the first week or so. Without pics, it's hard to make good recommendations on the beeb. | ||

What about a strip of gravel next to the driveway? Give the water someplace to go. | ||

Good thoughts above. ^^^ Sod would be fastest. Crusher Ron road bed gravel back filled under paving. A gravel strip will work wonders for drainage, and if you sift topsoil over top and seed it, grass will grow as it would naturally on a gravel surface over time, left without weed killer. | ||

"White rock". It's what they use for road beds here in Fla. Top w/black cow & throw sod on top of that. Chris C | ||

Good thougts. I'll probably scrape up the washed out gravel and respread it, and find some sod. I was thinking of seed...but sod is definitely quicker. And worst case...I can "harvest" some from the edge of the woods. I'll just pack the gravel in best I can first. | ||

If you're gonna pack in the gravel mix a little sand into it to fill in any "gaps". Then lay the sod. I had the same problem with a slab deck I laid earlier this year. I laid 500 slabs, it rained for a month & I then had to relay 200 of them due to erosion. The sod trick worked well for me & I had no subsequent problems w/erosion. (Plenty of sore back problems though!) |
