“Reducing the Moisture Content in Poured Concrete Slabs”


“…As environmental and workplace-safety regulations have limited the use of solvents in recent years, adhesives manufacturers have introduced water-based formulas with greatly reduced VOC emissions. For all their upsides, these adhesive formulas are less tolerant of moisture, making excessive moisture in concrete slabs a significant concern with certain types of flooring. When testing reveals that the slab might not be dry enough in time for flooring installation, installers have several options for overcoming excessive moisture in new construction.
When the project is in an enclosed space with at least a month before the flooring has to go down, the team might consider hiring a professional company to speed up the drying with desiccant dehumidifiers. However, without proper drainage and an effective vapor retarder beneath the slab, it will be difficult to dry the slab by any means. In that case, or if time is short, the best solution may be to slow the release of water with a specialty sealer…”

    Hi, Major problem and I really need answers.
    My house burned in April of 2018. House has been rebuilt.
    We have a slab foundation, in Plano TX. Our house had a swanky snake pit living room popular in the 60s and early ’70’s.

    To facilitate wood flooring throughout they poured 3 inches of new concrete in the Snake pit 9 months ago. It’s dead level and looks awesome. However the flooring guy put a moisture meter on it today and all the old 45 year old concrete is less that 3 on the meter.
    How ever all the new concrete in the living room … The needle goes all the to the highest reading.

    What would cause thIs there anyway to dry this area.

    Does the fact the original floor they poured over was brick have any bearing on this?

    Please, any information you can provide would be awesome
    Thanks,
