Egress window next to driveway.

I hope this is the right place for this thread.

I want to make my basement bedroom legal by installing a egress window. There's enough info already on the web to figure it out except for one snag. The driveway is about 46" away from the house. An egress window well will be at least 36" I believe. The soil around here is nothing but sand once you get under the sod.

Questions:
How do I keep the sand from coming out from under the tar driveway (and collapsing it) while digging the hole?
Is having a egress window well so close to the driveway a code violation?


thanks

Could you post pictures of this? We just can't see what you see, and word descriptions may not convey enough for a proper answer. http://www.doityourself.com/forum/el...your-post.html

I think you would need to put up shoring as you dig. Basically, dig 3 1/2" or 5 1/2" deep, (making the hole larger than needed) then put up a pressure treated 2x4 or 2x6 u-shaped perimeter. Then dig 3 1/2 or 5 1/2" more, and put up more shoring underneath that each time. If needed you can screw vertical supports to tie it all together, which would be removed once you get to your final depth... replace them with some steel form stakes at the bottom.

Since this borders a driveway, you will obviously need a curb or retaining wall around it. I would probably use the shoring you install as the outer part of a concrete form, build an inner concrete form that can be removed, and pour a footing and perimeter wall.

Here's a pic I had the wife take.




Do you mean using horizontal slats to keep the soil back? What keeps the slats back? Maybe pipes driven 6' into the ground?

Why not use a standard window well corrugated metal or fiberglas insert. It will double as a soil retention measure while allowing the space needed for egress. You will need to consider a drain for the well as water will make its way into it and needs a place to go. Expensive, probably. Example: Wellcraft 2062 091 Sandstone Granite Window Well-020620191 - The Home Depot

I just did a quick search on window wells and Lowes has this selection which would work as a dam and well a lot cheaper

Just a reminder the O/P's question was:
How do I keep the sand from coming out from under the tar driveway (and collapsing it) while digging the hole?
I'd try three or four steel drive type fence posts and 1x6s. dig down a few inches, drive in posts add a 1x6 behind the post to hold the sand then as you go deeper drive the posts deeper and move the the initial 1x6 lower and add 1x6s on top of the first 1x6 as you deepen it. Do not use the driveway till completed. Install a prefab as suggested above and remove 1x6s and the posts.

Good ideas thanks all. As far as drainage goes I was hoping to just cover the top with one of those window well covers. My thoughts were that the minimal water that got in would drain on its own what with the soil being nothing but sand. I could put in a few inches of pea gravel in the bottom of the well also maybe.

One more question. Is there anything I can soak into the ground to make the cement "set up" some kind of cement product?

You don't use cement you use concrete and it will harden even under water so I'm not sure what you are asking or why.

Sorry I meant to say sand. Can I firm up the sand somehow before digging?
