Concrete high water table no vapor barrier Tacoma, Wa

Hello everyone been lurking for a while. Just purchased a foreclosure condo in Tacoma, Washington area. The cement floor underneath the carpet apparently has no vapor barrier. The HOA representative said that in a law suit all they were able to get was enough money to drain around the exterior of property. Obviously it rains a lot here and you can definitely smell the moisture smell when you first walk in. Tore up the carpet and have found some cracks as well. Obviously I need to fill the cracks prior to trying to seal the concrete.

I am wondering what your recommendations are for what to put on top of the concrete. The inspector said it had a higher gloss which would make acid etching difficult so I'm trying to decide if I should just try and seal it with some sort of paint/sealant, and then carpet. Then encourage my future tenants to run the house circulating fan 12 hours a day.

I will be living in the property for one year and then plan to hold for 10-15 years as a rental.

In a mid to high end neighborhood so I think laminate is out of the question.

Thank you in advance!

You might consider epoxy-coating the floor - etching with acid pulls the gloss & any sealer off concrete like you wouldn't believe. The epoxy can be troweled into any cracks worth plugging. I wouldn't worry too much about any crack under 3/16" - all concrete cracks.

If there are "ridges" in the concrete, or if it's wavy, concrete can be ground flat. I'd hire that out if you need it done, it makes a hell of a mess.

You might consider the epoxied concrete as a finished floor, or carpet over it. The pros can make epoxy look pretty cool.

If you wanted to tile the floor, you can get a trowel-on "membrane" called "red guard" at the depot - it'll block moisture & prevent cracks in your new tile.. I know I'm in a different climate than you, but around here, tile everywhere is all the rage- its cheap to install and lasts until its out of style - tenants can get big rugs at Costco for the bedrooms if it's too cold, and they aren't worried about getting ripped off for minor stains in carpet.

There are similar liquid glue-membranes that can be used to even glue down "real" hardwood if you want.

Lots of options.. I wouldn't resort to running the fan all the time - I don't see that working.

    If the propertyis properly drained, than it shouldn't be a problem. Teh smell you are smelling is probably residual. If it is not properly drained as claimed, or you are still worred about it, nothing would work better than installing wood flooring on 1x4 screeds. That would allow the floor to "breath". I don't see a topical application of epoxy or any other "sealer" as a solution as the adhesion is usually not enough to seal against the vapor pressures that build up over time. I might consider a sealer in combination with the screeded floor as a belt and suspenders approach.

    I don't know what to cover the concrete with, but I would fill the cracks with epoxy by forcing it in. Home Depot sells it in the concrete section. It's expensive. $20 for a caulk size tube. Get the extra strength kind. It has a nozzle that mixes the two parts at the point of exit. I use it to waterproof cracks in foundations and it works great.

    Force it into the cracks and smooth it out with your finger. (Wear a latex glove).

    Matt Buckles I see this is your first post on the site so would like to welcome you to the BP forums. Glad to see another investor from WA area. I have a MHP in Lakewood and the city does not have storm drains in place for excess water runoff so we have a French drain in place to keep the water from pooling in he MHP. I am not sure how much you want to spend on the property, but if you will be living there, you might want to dig out all around the home and have the water run away from the foundation to a French drain area. This will help keep the 52 inches if annual rainfall from turning to mold under your home.

    First make sure you have a full perimeter french drain system with sump pump installed to control water. Then, you should avoid carpeting the basement. Not so fond of laminate or hardwood on concrete sub-floor surfaces; Mike Holmes had an episode on wood on concrete sub-floors that showed lots of issues. I like vinyl plank flooring for basement floors that need a finished surface; inexpensive, durable, and water resistant.

    Thanks for all of the replies everyone.

    Plan: Redguard and porcelain tile main hallway kitchen and bathrooms which is roughly half the condo. For the rest install carpet with stain resistant pad 8lb pad and the carpet is made from recycled water bottles. Going to pick out tile today and contractor should have everything ready for me to move in next week.

    Here are my numbers for this property

    Purchase price: 112,620
    Comps in area: 149-165,000
    20% down 3.46APR

    Expected rental income 1200-1325 (after 1 year to satisfy hud).
    Mortgage+insurance+taxes+HOA=780.

    I would still install a moisture barrier membrance (not coating) beneath the carpet pad. Use something such as Dimplex or Superseal to stop WV transmission. Flooring is expensive but proper underlayment isn't in the long run.
