Maybe some Envirotile? https://www.homedepot.com/s/envirotile?NCNI-5

We're using them as a temporary patio while we decide what we're doing for a new deck. So far they've gone through a full year (fully exposed) and they look basically brand new.

Re: Area under deck gets muddy, what to fill with?


As others have mentioned the problem is two-fold and it is more than rain coming down through the deck. There is ground behind the short block wall and it is going to be acting like a sponge to let water percolate down the grade and to the area where the flooding has occurred along with the damage to the exterior wall.

Excavating the dirt away from the house is the first step. That may be enough or you may need to run a French drain to carry the water further from the house.


Putting anything over the ground will accomplish nothing as the water will still be there and it will be wicked into the walls of your house (and this will be expensive to repair.


Good thing is that it appears that you have easy access to this area to bring in a Bobcat and fix the grading around your house. You have to fix a defect created by the home builder and overlooked by the inspector (not uncommon).

Is regrading really necessary? It looks like the house is on a hill, with the back lawn sloping downwards away from the house. Could the OP put in a french drain in the lowest spot under the deck, and route the pipe to an outlet somewhere on the hillside? As long as the drainpipe is always flowing downhill, that should move the water away from the soggy spot, even if there's a "dam" that blocks the flow at the surface.

This is a bit more of a DIY-friendly project than renting a bobcat. Especially if the OP uses a prefab french drain. All he has to do is dig a trench with a shovel, toss the drain in, and fill it back up.

Oh, and as long as that spot gets a decent amount of sun, grass will grow there once the swamp is drained. Just loosen the topsoil, maybe mix in some compost, sprinkle grass seed, and wait. Best done in early fall.

He has a drain pipe for the downspout, he can tie a drain into that.

Re: Area under deck gets muddy, what to fill with?


Thx guys. That area i highlighted is very flat... hence no water draining onto the hill slope.

Been talking to a Mason.
He suggested gravel or concrete. Will give estimate soon.

1)
If concrete he'd dig the dirt enough to give a sloping (or French drain).

Btw i already have a French drain for a sump pump inside walkout basement. It was stagnating water so installed it, extended the piping 10 yr ago. Works great even now.... drains ~30 feet downhill .

Maybe i can route it to same French drain?

2)
If gravel he suggests a tiny sized one that's easy on the feet.. Over weed prevention sheets.

Does he still have to give a slope for gravel?

3)
If you see to near the house wall i have hostas should i start the work from that little area that goes in a bit near the a.c condenser so any future seepage doesn't affect the house?

Initially thought I'll leave that 3.5x9 feet area for existing hostas !

Please advise the 3 questions above.
Appreciate everyone chiming in

Re: Area under deck gets muddy, what to fill with?


You hostas garden is about 10 inches to high, there should be about 6" of foundation of the house showing everywhere. If you do gravel the dirt below the gravel needs to have a slope so the water runs away from the house. I doubt you would be happy with pea gravel, if that is what he is talking about.

You detached the footing drain from the sump? Or added a separate outside drain (I see a greenish corrugated pipe by the corner) that empties in the backyard?

It sounds like you were originally just going to get some cheap 16" patio blocks to lay down on the dirt. I see a three-fold path depending on your budget, sweat equity, or if you want to match the value of the house:

- Fix the water: You have to dig down, slope away, maybe add french drain. The dirt (with a little gravel on top) by the downspout is too high. The dirt at the hostas is too high. That will cause rot and bugs. It should have 6"-8" of exposed concrete foundation below the stucco. Whether you put back gravel, pavers, concrete or grass is your decision.

- Clean it up: Move the hostas out. Hardscape (gravel?) that area to prevent the dirt splashup and algae. Allow clear space around the a/c condenser.

- Usable space: You have a desirable walkout not being utilized. Unfortunately the deck builder placed a stair post in the way. But if desired you could put a patio down there that connects to the stair. It could be pavers, concrete, or chipped stone (no pea gravel). Since you get sun below, you could even leave it grass, just keep an area clear next the house and around the a/c condenser.

Thx,
The townhome came with sump pump output just ending where hostas are, later i connected a long buried tube into a French drain downhill. Not in pic.

I never knew you need exposed foundation below stucco. You're right that hostas area is always buggy, wet.

I think I'll do gravel where hostas are too and ensure they slope away. Container plants in gravel looks good!

When i search pics in Google i see different color pea gravel.

What kind of gravel good for this project? I don't want too dark.

Are wood beams good as border for gravel patio?

Just to clarify, a french drain is a pipe with holes in it. If you are putting the sump water into a french drain near the house, it will spit water out all along this pipe. Hopefully, you are referring to a small solid PVC pipe extension underground under the deck that eventually meets up with a french drain in the backyard.

There are different methods of stucco, and I'm not sure how they finished the bottom transition detail. Keep the soil below that and you'll be safe.

You can get all different colors of chipped stone or even river rock. "Pea gravel" is a certain type that will move around too much when you walk on it. Stay away from any wood buried in dirt, it stays moist, rots and attracts unwanted problems.

Yes, a long pipe under grass then to French drain at exactly where i stood to take first pic.

Just realised most townhomes here don't show foundation, community is on hill for sure!

I thought treated wood cheaper to replace every 2 years, to be a border .

To reduce cost what if i fill the gravel after i shop for it after Mason slopes the dirt, nails the weed preventer?

Should i get from HD , LOWE'S or some other discount place for various gravel at best rate? Thx

Here are 3 pics.

Stucco absorbs water and it drains out the back to the bottom, when you have the dirt to high the water can wick up behind into the wood structure.

The wood structure is the same level as the bottom of the doors.
