Quick Answer: How To Install A Basement Floor

What type of flooring is best for basements?

What basement flooring options and materials are the best? The best type of flooring for basements is vinyl. Vinyl flooring can come in the form of vinyl plank and vinyl tile, giving it the ability to look nearly identical to hardwood and stone products with the added benefit of being waterproof.

What kind of concrete do you use for a basement floor?

Concrete is the most commonly-used material for basement floors because it is inexpensive, durable, easy to work with and versatile. Smooth concrete can be easily covered with your choice of flooring, made to look like marble or stone or even just painted.

Does a basement need a subfloor?

Subfloors are not always necessary but they are beneficial wherever they can be installed. They only come into play when you want to expand downward and make your basement a warm, livable space. If you don’t plan to use the space, there is no need for a subfloor or floor covering.

Do I need a vapor barrier in my basement floor?

If you have a concrete floor that’s in continuous contact with a source of moisture, you’re going to have problems. This is why a vapor barrier under concrete is essential. Vapor barriers are a way to keep moisture from getting into the concrete. Note: A vapor barrier is not the same as an underlayment.

Do I need a vapor barrier between concrete and wood flooring?

Do I need a vapor barrier for hardwood floors?” The answer is YES! Moisture can destroy hardwood flooring. It causes cupping, warping, and even mildew if not treated. You must install a moisture barrier to protect your flooring from water wicking up from below.

Does concrete need to breathe?

Foundation walls like concrete are porous. This means they can take in 10-15 gallons of water vapor a day. That is why your walls need to breathe. Moisture needs somewhere to go, and a house that is sealed up too tight ends up with moisture in puddles and rotten drywall.

What underlayment should I use on concrete?

With a concrete subfloor, you will need an underlayment that acts as a vapor barrier in order to prevent moisture from penetrating through to your laminate installation. The normal choice is a thin foam pad material made of polyethylene or polypropylene, which rolls out in sheets.

Can mold grow under vinyl plank flooring?

Although vinyl flooring is known to be waterproof, liquids can still seep through the grooves, edges, or unsealed seams and get trapped underneath the flooring, causing mold to grow.

Can you put vinyl flooring over concrete?

Generally speaking, you can install vinyl tile directly over concrete, provided there are not any serious problems with the concrete floor. Any concrete floor used as a subfloor for vinyl tile must be clean, dry, and smooth. If there are any cracks or holes, they must be repaired first.

What is better for basement vinyl or laminate?

The winner of laminate vs vinyl flooring is really up to you. Both are strong, beautiful floors that are less expensive than natural wood, but if easy installation is your most important factor, laminate flooring is the more DIY friendly option (though we have plenty of instructions on installing vinyl as well!).

How thick does a basement floor need to be?

A. The average thickness for a basement floor should be 4″. If you have any load bearing walls, columns, or a chimney, these areas should have footings already in place before the floor is poured.

Do you need gravel under concrete?

Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.

Can I pour cement over dirt?

Long story short, yes you can pour concrete over dirt.

What should I put under my basement floor?

Wood panels, such as plywood or oriented strand board, are common subfloor choices. However, because wood is a naturally porous substance that will absorb moisture, when used as a basement subfloor, these materials are often installed on mini-joists known as “sleepers,” which allow it to sit above a concrete pad.

What is underneath a subfloor?

Underlayment The underlayment material is installed below the floor covering and placed on top of a sub-floor. Under the visible covering, there is a layer made of soft or foam-like materials with a thickness of between 1/4- or 1/2-inch.

Can I put plywood over concrete floor?

If you’re installing plywood over an existing dry concrete floor, you shouldn’t have any problem. However, a new concrete floor contains a lot of moisture. The moisture level of the concrete should be down to 5.5% before attaching the plywood subflooring.

Do you put plastic under concrete?

In California they place sand between slabs and plastic vapor barriers—in Florida they don’t. Almost everywhere (except “California”) that slabs are placed on the ground—a plastic sheet—a vapor barrier—is located directly under the concrete slab and on top of the ground (Photograph 1).

Should I seal my basement floor before carpet?

Sealing your basement floor before installing carpet is a good idea. Installing carpet also helps to insulate the interior of a basement by keeping the floor warm in cold weather. Applying some type of sealer on a slab floor before installing carpet will prevent condensation as well as protect the slab.

What is the difference between a vapor barrier and a moisture barrier?

These two terms essentially refer to the same thing. Moisture barriers and vapor barriers are both building materials designed to prevent water from getting past the barrier. No vapor barrier is capable of stopping all moisture from passing through.
