OT: concrete driveway advise Options

[thomasotten]

I have a problem. My house and driveway is lower than the street level. Usually, when this is the case, they will build a slight rise or berm into the driveway near the street, to keep the street water out. Unfortunately, there is no berm, and when there are heavy rains, I get a lot of street water. I have determined that if I built a berm only 3" high, it would prevent the majority of the street water from entering. So my question is this: Can I build a berm out of concrete directly over my existing driveway? Would it stick, would it break off? Any tips on how to do this so that it lasts? It would very much resemble a speed bump, same proportions.

Thanks,

Thomas

With a trench drain, you pitch it in one direction about 1/8 inch per foot.
At the lowest end, you dig a dry well.

The size of a drywell depends upon your soil...in Texas there is alot of clay that does not drain to well.
Up here...a decent drywell is about a 2 foot diameter hole, four feet deep.
Fill the hole with 3/4 stone up to and above the bottom of the drain...cover the stone with weed cloth and put a few inches of soil on top.
What that does is buy you time...the drywell gives a place for the water to go and then it has time to sink into the ground.
Again....its very dependant upon you soil...that is how fast does your soild perk...how lond does it take to drain the drywell of water..

And the other consideration is this. Do you get massive thunderstorms that flood the road? if so a smalll drywell may just overflow.
