I am buying a house that is under construction and should be complete in a month. The house is wide open and it is very humid here in the northeast. The basement is a walk out in back but underground on the front and sides of the house. I have noticed a damp area on the concrete floor all around the edges of the walls that are underground. It is a small damp area that is located where the wall meets the floor. It is a concrete block construction and the builder did install drain tile under the walls. Could this be condensation? Could this be a leak where the wall meets the floor. The dampness is only on the floor and the walls seem dry. There are no puddles, The cement just looks and feels wet.

The builder has assured me that I should have no water problems, once the house is complete and the landscaping is done, but will not gaurantee it. IS that normal?

It could be condensation or it could be leakage.

We are in a high humidity part of the year, the basement is realatively cool, a new house is giving up lots of moistures from the DW, wood, and concrete, and the AC has probably not been run much.

One test is to get about 2 ft sq piece of clear plastic and duct tape it to the floor. Wait 1-2 days.

If it is moisture coming through the concrete it will be dark or even have droplets under the plastic.

If it is condensation the concrete will be dry and you might have condensation on the surface of the plastic (or might not depending on the exact conditions).

Ask the builder to tell you exactly what was done for water proofing and damp proofing the basement.

And write those down and report back.

I will talk to the builder to get additional information, but what I know so far is that he did install drain tile all around the foundation and I have flexible tubing going down the side of my house into the back yard. They are on a downslope, so I assume that the drain tile is doing its job.

The AC has no even been turned on yet, He has just completed the ductwork. I will try the pastic idea and see what happens.

They just added the gutters to the outside so that should help with the water, but there is no lanscaping done and that will be up to me. I realized that grading the soil away from the house will help the situation but I am still concerned since it is a new construction.

Do most builders garuntee a dry basement?

All US states require all builders to warrant new homes to be free from defects, including basement water leakage, for at least 1 year and often as long as 10 years.

The only way a builder can offer you a home in which he will not warrant the basement for leakage is if within the building contract the home is offered with no warranty for basementleakage IN WRITING and it is agreed to be purchased BY YOU with no leakage warranty.

So you and/or your lawyer need to check your contract and determine if your basement is warranted or not.

And if you signed the contract with a no leakage clause in the contract, it becomes your problem, not his...unless he violated building codes in the process.
