Common Problems Installing a Subfloor Over Concrete

6 Feb 2019 How well would this accommodate the slope?” Installing any kind of finished floor on concrete without some kind of mould-resistant subfloor is a 

Common Causes for Moisture Problems. – Floor planks were not dry at the time of installation. – Sub floor is too wet. – Existing or new concrete slab is too 

A level subfloor, whether wood or concrete, is critical to a beautiful, finished floor. However, even the best sub-floors may contain slight imperfections. A quality underlay smooths over minor subfloor defects, providing a flat, stable base for your new floor. Noise reduction is the most significant benefit of an underlayment.

OSB is fast to install and less expensive than real wood or plywood, making it the go-to material for modern subfloors. Subflooring can last a very long time. Under normal conditions, a subfloor

High moisture and the high pH associated with it in concrete substrates are the most common causes for flooring failures," said Gary Scheidker, director of technical services, Taylor Adhesives. In commercial installations, resilient flooring is especially vulnerable when laid over concrete surfaces.

The most common problems with LVT/LVP installations are visible high spots, adhesive failure and buckling or gapping due to excessive flooring movement. Since luxury vinyl is inherently bendable and installation is directly over the substrate, the finished floor show surface height variances in the underlayment.

One of the most common questions people ask when installing engineered wood However if you're installing over a concrete subfloor, you must ensure 

If the subfloor is concrete, it might not have a vapor barrier installed underneath. If it's wood over Common Hardwood Floor Problems and Visible Signs.

However, the concrete is uneven in spots and our contractor brought up the idea of getting the concrete close to level, then building a plywood subfloor over top, then installing our luxury vinyl planks onto that subfloor.

Wood subfloors must be flat, clean, dry, structurally sound, free of squeaks and free of protruding fasteners. For installations using mechanical fasteners of 1 ½" and longer, the subfloor should be flat to within ¼" in 10 feet, or 3/16" in 6 feet. For glue-down installations and installations using mechanical fasteners of less than1 ½

The issue I am faced with is that the existing flooring sits at 1.5" above the slab so I need to install the new flooring at the same level. My plan: Install 7/16 or 3/4 osb over a vapor barrier, install my cabinets to the osb "sleeper subfloor" then install the 3/4" pine T&G flooring to the osb.

For stone and tile installation any subfloor that could shrink, expand or move in anyway requires a cement backer unit, or CBU, to provide stability and act as a moisture barrier. Given that most subfloors can shift overtime, using CBU has been a very common practice over the years.

When you are installing hardwood flooring over concrete flooring, there can be a lot of problems such as moisture, unlevel surface, and the damaged surface of the concrete flooring. If any of these conditions are seen in the concrete floor, the installation process would require extra work, such as repairing the floor, making it flat, and

Tile can contribute thermal mass to a passive solar house, and to Christa Campbell it would make a more appealing finish floor than concrete. Although tile can be placed directly over a concrete slab, products such as Schluter's Ditra are designed to separate, or "uncouple," the tile from any potential movement in the substrate and protect the tile and grout from cracking. The question

Concrete subfloors must be fully cured, at least 60 days old, and should have minimum 6-mil polyfilm between concrete and ground. Subfloor should be flat and level within 3/16" per 10' radius. If necessary grind high spots down and level low spots with a Portland leveling compound.

Without a waterproof sealing solution, such as CIM’s cold, fluid-applied membrane system, moisture will reach the subfloor through the thin set and tile system, thereby increasing the risk of problems.

Wood Subfloors. An alternative to pouring a new cement slab is to install a wood subfloor over old concrete. Uneven surfaces need to be leveled, and plywood decking installed on either 2x4 or 1x4 pressure treated lumber, spaced 16†on center. Installing a wood subfloor is not recommended, however, if moisture is a possibility.

Concrete Subfloors: a.Concrete subfloors must be finished and cured, free of all sealers, coatings, finishes, dirt, film forming curing compounds, or other substances that may prevent proper bonding of the flooring materials (ACI 302.1 and ASTM F710). b. Randomly check concrete subfloor for porosity using the drop water test.

All the common floating floor installation problems mentioned here are relatively easy to remedy generally. Still, you want to avoid floating floor issues out of the gate as a preference. If you do experience one of the issues, advice is to contact an expert to assess the situation to determine if repairs are an ideal way to go and, if not

When starting the installation of a new laminate, tile, hardwood, plywood, or any other type of floor on concrete, you can skip traditional concrete basement subfloor methods. Typically in the past, builders would install plastic sheeting and fasten wood slats on the concrete and cover with plywood.

A bad subfloor will not only ruin the look and compromise the integrity of a floor but is also a nuisance to fix considering you have to remove the top layer of flooring just to diagnose your subfloor problem. There are several common mistakes people make when installing a subfloor, but all can be avoided with the right materials and a little

Installing a wood floor over a concrete sub-floor can be tricky. The most important factor for a successful installation is preparation. There are three main areas of concern: structural integrity, a flat and even surface, and moisture content.

Repair and replacement costs between $1,400-$4,300 and include site prep, old subfloor removal, flooring removal and reinstallation, and cleanup. Materials: $3,600-4,400 for repair and replacement. $3,600-$4,200 for an install. Equipment: $30-$50 for tools for all project types. This can include saws, nailers and planers.

Subfloors that are below grade (underground) or ground level floors in buildings without basements typically have a concrete subfloor. Subfloors above grade
