Default Putting Concrete Floor in Crawl Space

I'm wanting to put a concrete floor in a portion of my crawl space. I've already cut out a bigger opening and put in a door. I've also started digging out the dirt floor in order to give me more head room and a level floor. Here is a picture of how it looked before I started digging.

As I've started digging down I've run into a few issues. The first is that I'm getting standing water when it rains. Should I look at adding a sump pump in? Also the block columns supporting the floor do not go down as low as the footings do. Can I put up a block wall or pour a concrete wall along side the columns before pouring the floor? Also what tips would you give as far as a base before pouring the concrete. Please excuse the mess. Any other suggestions or advice would be greatly appreciated. Thanks

When I dug down, I went all the way to 7' deep. I left 18" of undisturbed dirt from the footings and built a cinder block wall. I installed a sump pump without installing drain tile. Where the center support was, I removed the block and put in a standard metal support. A solid concrete block under the area where it is under the concrete is all I did.
Was it a perfect job? No. However, I will argue that getting the moisture level down and getting a sump pump and furnace down there is why that house is still standing 20 years later. I had to replace several floor joists that were rotting out due to a damp crawl space. No more pipes freezing in the winter either. Good luck, you're getting there!

With as damp as the dirt is and as close as you dug to the footers and piers, you want to keep a close eye on things not caving in and either cracking your footing or your piers shifting.
You'll need a sump pit & sump pump if you are getting standing water. Then you should have a good bed of gravel down before any concrete is poured.
You could tile around the base of the foundation on the inside and tie this tile into the sump pit. That way any water coming in at the base will weep into the tile, go to the pit and out. You'll also want a vapor barrier down underneath the concrete.

Good luck. Looks like you have a lot of it whipped but still have a ways to go. Keep us posted with pics.

Install a perimeter drain to the sump pump. 3 to 4 in. of crushed rock with a vapor barrier then the floor. Can you dig on one side of the support inline with it,install a new support and finish the wall? If you do put a thickened edge on your slab to act as a footing.

Go to Building Science Dot Com and read about conditioned crawl spaces

Default Re: Putting Concrete Floor in Crawl Space

Time for an update on my crawl space. Last month I rented a small trackhoe to finish excavating the floor. My dad came up and helped. That was a long day. This month I've been working on digging a trench, setting forms, and pouring a footing for a block wall so I can put in drainage to control my water issues.
Before

It barely fit through my gate and door

My dad brought his small tiller to help loosen up the dirt.

Had to buy some new lights as my old T12s quit working

Footing dug, form and rebar set ready for concrete. Mixer was a craigslist deal, was still new in the box.

Concrete poured today


I hope to get to the block wall the first part of July. Does anyone know how long I need to wait before I can remove the forms?

You can remove forms the next day. I assume your going to epoxy dowel your uprights for the block wall?

Just curious, have you had a building inspector check what you're doing?
