If your home was built on a concrete slab, and you want to enjoy the beauty and charm of hardwood floors, you need to consult an experienced professional who will manage moisture and minimize wood floor expansion and contraction when preparing to install hardwood floors on concrete slabs.
If the concrete is dry, then solid hardwood floors can be installed on slabs that are either at ground level or above ground level. Make sure that the slab must be flat with a trowel finish, free of grease, oil, stains and dust. But before installing hardwood, go through the internet and check out the pros and cons, the products and all other items that are needed during installation.
