Hello City Date,

-Summary-
My parent's recently hired a general contractor to design, and implement, a plan to manage the water that has been collecting on the side of their home, and causing moisture to build in the basement. After the water issue has been resolved they plan on poring additional parking space off of the main driveway to the side of the home.

I don't have any experience with these sort of projects but it's my belief that simply digging a ditch and filling it with stones is not going to help fix the problem, we need to move the water away from the home, not capture and hold it. The ditch they recently dug is not event graded to help push the water down the hill/driveway which is behind me in the photo I took.

My question to the community should I let the contractor continue with his work, should we terminate the project, or should try and work with him to design a different plan of managing the water/driveway?

Thank you,


-Contractor Proposal-

Project Challenges:


a. Water currently pools around the foundation eroding the landscaping and potentially entering the basement level through infiltration.
b. The family needs two more parking spaces.

Suggested Approaches:

a. Water drainage issue—dig a 70 ditch 24”wide by 12” deep on the right side
house filling it with 57 stone. Connect the adjacent gutter downspouts to the
ditch, level the AC units, and re-grade against the house so that water does not
pool. Re-grade the right rear of the house to keep the water from eroding the
foundation.

Re-pipe both front downspouts so that they drain down the front left side of the house.

Supplies—15 tons stone, 60’ 4” PVC + fittings, 20’ of 4” landscape pipe $660
Day Labor—2 men, 5 days 185/day $925
Rich’s Time—5 days $750
Total: $2335

b. Concrete driveway—create a drive and approach enough for 2 vechicles
approximately 60’ long by an average of 8’ wide.

Supplies—2x4 forming material, stakes, rebar, plastic $325
Concrete—7 yds of concrete $135/yd $945
Day Labor—2 men, 3 days 185/day $555
Rich’s time—3 days $450
Total: $2275

Note: 10 tons of the stone in the “a” part (water drainage) is for the base
on the concrete part of the project. Also, the labor portion may be
one day shorter in time depending on the dirt consistency any other
factors but will not exceed the above quote.

Broadly speaking, your contractor is headed in the right direction.

The proposal includes 80' of pipe...some perforated drain pipe, and some 4" drain pipe.

If I understand the approach, the idea is to dig down to a certain level, lay in a little bit of crushed stone, lay in the perforated pipe whose function it is to collect/capture the water, cover the perforated pipe with the remainder of the crushed stone, connect this perforated pipe to the drain pipe which will escort the captured water away form the house--presumably to 'daylight' or some existing storm water drain system.

If that is broadly correct, then I would say your contractor is headed in the right direction. I believe it is called a French Drain. The picture you included shows the trench where the perforated collection pipe will be installed, and it does not include the balance of the ditch which takes this water away from the house. The objective is to capture the water and drain it away to another location.

It sounds like you might be uncertain about this approach. What is on your mind that we be broadly different that you think should be going on in the solution?

If all he is doing is laying in the perforated pipe in that 'closed' ditch, then there will be no improvement. The water needs to be able to drain AWAY from that area where it is pooling. After re-reading your post, and asking for suggestions: yes, either get him to explain how that water is going to drain away to daylight, or work with him to implement a solution which will ensure that the water gets drained away. What he has done--per the picture--will not resolve anything.

First question to you is did the Contractor explain in detail what he was going to do to fix your problem.

Your supplies list and your explanation don't fit.

It appears that the contractor is going to construct whats called a modified french drain with perforated pipe encased in drain rock hopefully falling away from the house at least 1/8inch fall per every foot for travel.

I dont see any landscape fabric in your materials list which should be included to line the ditch so dirt doesnt infiltrate the drain rock reducing its effectiveness over time to move water to the pipe.

FYI I didnt answer the poll because its more complicated than those simple answers.

Nice moat you have there. You could get a boat and charge the neighborhood kids rides. LOL

The first two responses make a lot of sense. I'm guessing your house wasn't built with foundation drains? Someone please correct me if I'm off base, but 24" seems mighty shallow for any French drain. These are always complex projects. I'm afraid I can't vote either.

Tina it appears that its a modified french drain system. It will have a perforated pipe near the bottom of the trench to pick up water that filters into the rock and carry it away. Also connecting downspouts to carry water away as well. the contractor need to ensure that the rock and pipe is encased in water/air permeable landscape fabric to keep dirt from settling into the drain rock and pipe clogging it over time.

Personally I don't like this system and prefer to use hard pipe with drains every where. That does mean proper grading. Some time you have no choice and need to go all around the foundation with this modified french drain system because of the water table in the area.

I don't know... this looks awful lot like what we had done. Then the water ran next to the driveway and broke up the cement and dirt is carried into the street. We still haven't fixed it.
