What is a raised floor?VIDEO ON THE TOPIC: Epoxy Flooring Step by Step
Even if your home was built on a concrete slab, you can still enjoy the beauty and charm of hardwood floors. Experienced professionals pay close attention to managing moisture and minimizing wood floor expansion and contraction when preparing to install hardwood floors on concrete slabs.
Here are items you should consider before the job is started. At or Above Grade With dry concrete and the right subfloors and vapor retarders, solid hardwood floors can be installed on slabs that are either on-grade at ground level or above-grade above ground level. Moisture can pose problems for solid hardwood floors below ground level, so engineered wood floors made of layers of wood glued together are the best choice there.
Protect the Flooring. Wood floors should not be subjected to very wet conditions. Before delivery to the site, the building should be closed-in with outside windows and doors in place. All concrete, masonry and sheet-rock should be completely dry. In warm weather, the building should be wellventilated.
In winter, heating should be maintained near occupancy levels at least five days before the flooring is delivered and maintained from that point on. Dry Slab Concrete slabs, whether new or existing, must be dry before the subfloor is installed.
For best results, several areas of each room should be tested for excess moisture. If tests indicate too much moisture is in the slab, do not install hardwood floors.
A new moist slab should be allowed to dry naturally or the process can be hastened with heat and ventilation. Slabs less than 60 days old are generally too wet to install floors. Test for Dryness New concrete is heavy with moisture, and it must be a minimum of 30 days old before moisture testing begins. Determining moisture content of both the wood flooring and the subfloor is an important part of quality control in the flooring installation process. Detailed qualitative and quantitative testing methods are provided by the National Wood Flooring Association.
Flat, Clean Slab The slab must be flat with a trowel finish, free of grease, oil, stains and dust. Grind off any high spots and fill any low spots. Vapor Retarder With solid hardwood floors, a proper vapor retarder must be installed on top of the slab to make sure normal slab moisture does not reach the finished floor.
Layers of asphalt felt with asphalt mastic or 6 mil polyethylene sheathing are some of the choices. Subfloors The National Wood Flooring Association recommends two choices in sub-flooring systems for concrete installations: plywood-on-slab and sleeper. Either subfloor system is satisfactory for three-quarter inch flooring. Asphalt felt or building paper: first, prime the slab and apply cold, cut-back asphalt mastic with a notched trowel 50 sq. Allow to set for two hours.
Unroll lb. Over this, apply a second similar coating of mastic and roll out a second layer of asphalt or paper in the same direction as the first, staggering the overlaps to achieve an even thickness.
Polyethylene: Cover the entire slab with 4 to 6 mil polyethylene film, overlapping the edges 4" to 6", and allowing enough film to extend under the baseboard on all sides.
When moisture conditions are more severe, prime the slab and apply cold, cut-back mastic with a straightedge or fine-tooth trowel sq. Lay 4 to 6 mil polyethylene film over the slab, overlapping the edges 4 to 6". In either case, roll the film flat or "walk" it in, stepping on every square foot to ensure adhesion. Puncture bubbles to release trapped air. Install the plywood after the vapor retarder is in place.
Lay plywood diagonally across the direction of the finished floor to help prevent cracks along panel edges. Do not use power-actuated fasteners or concrete nails when radiant heat pipes are embedded in the slab. Lay panels in a staggered pattern with at least 2' long planks along starting and finishing walls. For systems other than radiant heat, the plywood planks may be glued to the plastic with asphalt mastic.
Floating subfloor of 2 layers of plywood secured together over a vapor retarder. No fasteners penetrate the retarder or the concrete. Sleepers Flat, dry, kiln-dried, preservative-treated 2" x 4" sleepers in random lengths 18" to 48" can also serve as a nailing base. Otherwise, yellow pine, fir or other kiln-dried framing species is acceptable. Begin by sweeping the slab clean, applying an asphalt primer and allowing it to dry.
Before installing the floor, loosely lay an additional vapor retarder of 4 to 6 mil polyethylene film over the sleepers, overlapping the edges on top of the 2 x 4s. Avoid bunching or puncturing the film, especially between sleepers. Acclimation When the site is prepared, the flooring can be delivered and stored in each room where it will be installed. Without a proper moisture meter, you cannot determine if the flooring has been properly acclimated.
The flooring should be removed from its boxes and all packing materials during this process. Mastics and Trowels Hot asphalt is generally used only for laying screeds on concrete, and the screeds must be positioned immediately upon pouring the mastic always follow manufacturer's directions. Cut-back asphalt, chlorinated solvent and petroleum-based solvent mastics are all applied cold and are used for laying tongue-and-grooved block and parquet floors.
Follow your manufacturer's instructions on coverage, drying time and ventilation. Use a notched edge trowel when a correct mastic thickness is specified. Solid parquet hardwood flooring can be glued directly to a concrete slab on grade or above grade with the use of a manufacturer recommended vapor retarder. Solid parquet should not be installed below grade.
The entire flooring level is considered to be below grade where soil is present along any perimeter wall and is more than 3" above the installed wood flooring level. A vapor retarder is always required over the concrete slab and below the subflooring material.
A minimum 6 mil construction grade polyethylene film, with perm of. In such cases, follow wood or adhesive manufacturer's recommendation. NWFA recommends using the manufacturer's suggested adhesive. Successful installation also requires conducting a concrete slab moisture test before parquet installation. Solid flooring may be installed directly to the slab.
Installing a hardwood floor over a concrete slab Even if your home was built on a concrete slab, you can still enjoy the beauty and charm of hardwood floors. Protect the Flooring Wood floors should not be subjected to very wet conditions. Plywood on slab Begin by covering the slab with a vapor retarder. Nail the finished flooring to the sleepers through the film. Gluing Solid Parquet Flooring Directly to a Concrete Slab Solid parquet hardwood flooring can be glued directly to a concrete slab on grade or above grade with the use of a manufacturer recommended vapor retarder.

The aim of this article is to highlight the requirements that may exist for a given building project, and indicate how these requirements should drive the designer towards the most appropriate and cost effective choice of floor system. The range of steel based floor systems is presented in general terms, with the advantages and disadvantages of each system identified so that these can be compared against the requirements of a given project. The article does not go into technical detail about the different types of composite , long span , and shallow floor solutions. Different buildings have different requirements, so not surprisingly there is no 'one size fits all' most appropriate solution. Clearly the requirements vary depending on the type of use, but there are also some more subtle issues to consider and these are highlighted below. It should not be forgotten that when considering intended use, it may be appropriate to pay attention to a different use in the future - many steel solutions offer flexibility that can result in high levels of sustainability over the lifetime of a building.

The traditional post and panel raised access flooring system was introduced in the s with the primary purpose of providing cooling and air flow to the large computer mainframes of that era, as they ran exceptionally hot. A traditional access floor creates a sealed air space called a plenum between the raised access floor and the subfloor. The plenum is there to accommodate and contain underfloor air distribution UFAD. These floors can be installed at a variety of heights, from 6 inches mm to 4 feet 1. The height of the posts is dictated by the volume of cables and other services to be stored beneath the raised floor; the typical height is somewhere between 24 inches mm and 48 inches mm.

Water is an inherent part of the hydration process of concrete. Once the slab is poured, the excess moisture must leave the slab in order to strengthen the concrete bond. The slab must also dry to a specified level of moisture before flooring materials can be installed on top of it. Moisture-related damage to the flooring materials is possible. Three common floor materials run the risk of moisture-related problems :. Are you seeing a theme yet? The real risk to a successful floor lies with the moisture that can accumulate within the layer between the concrete slab and the flooring itself. Responsible moisture control having accurate moisture measurements starts with the concrete slab. For moisture to accumulate between the concrete slab and the flooring, it needs to find its way to that middle layer. In this section, we breakdown the main ways water can get into your concrete, which causes a buildup of excess moisture, and list effective methods to prevent moisture problems from occurring.
Flooring is the general term for a permanent covering of a floor , or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials. Materials almost always classified as flooring include carpet , laminate , tile , and vinyl. The floor under the flooring is called the subfloor , which provides the support for the flooring. Special purpose subfloors like floating floors , raised floors or sprung floors may be laid upon another underlying subfloor which provides the structural strength. Subfloors that are below grade underground or ground level floors in buildings without basements typically have a concrete subfloor.

It's hard to imagine a house being cozy without the warmth of wood flooring. The quickest way to get new wood underfoot is to install a floating floor. Unlike traditional solid-wood strips, a floating floor isn't nailed down. Instead, the planks are either glued or snapped together. The planks go down fast, over virtually any material—concrete, plywood, sheet vinyl, even ceramic tile.

I'm trying something new, normally when I do a shower pan I use the hot mop method or pre slope with liner then deck mud for shower floor. But I saw a product called speed slope and saw how this method works, I want to apply it straight to the concrete slab with the normal slop to the drain, then a 2 application of Red Guard to water seal, using this method would eliminate the liner, now is there a type of bonding agent I can use for the speed slope to adhere to the concrete slap, do you think this can work Hi may I know what is the standard curing hour or days for the topping works before the tile installation.
Interior finishes and space-division systems define the living spaces within residential buildings with a range of both natural and synthetic materials. The most widely used wall finish is gypsum board , a prefabricated form of traditional wet plaster. Wet gypsum plaster is cast between paper facings to form large panels that are nailed to light timber or metal frameworks. The joints between the panels are filled with a hard-setting resin compound , giving a smooth seamless surface that has considerable fire resistance.
