Subflooring is an exciting subject in construction. It’s a method of laying base subfloors over the uneven concrete pavement. Just like other surfaces, it’s essential to ensure that the base subfloor is solid enough to withstand the weight of the future floor.
How to build a subfloor over uneven concrete? It is a great question to help everyone understand their needs and problems. Especially when they can find out how to solve this problem, they will be able to build a subfloor over an uneven concrete floor. Let’s further discuss this in detail.
Why is it essential to build a subfloor?
Over time, concrete expands and contracts, and it can change the shape of your floor. If you attempt to build your subfloor on a concrete slab that’s already stabilized with a concrete cap, you may end up with a warped floor. To avoid this problem, make sure you use a concrete cap that doesn’t have any air bubbles or cracks in it.
Building subfloor over uneven concrete can be challenging, particularly for home renters new to subflooring. In the case of rough concrete, you must take care of your subfloor in order not to cause any damage. If your concrete is uneven, you may get cracks and crevices that can cause many problems.

What is concrete?
Concrete may be defined as any material that is capable of withstanding vibration. We use concrete in various applications, including construction, engineering, and building maintenance. A concrete floor consists of a concrete slab, usually one and six inches thick, and a cement-based cement board. We generally lay concrete foundations on subflooring, a layer of ground cover designed to protect the concrete floor from moisture and snow accumulation.
Concrete refers to concrete flooring when you’re talking about concrete and subfloor. The subfloor relates to what’s under the concrete, like the floors underneath the concrete.
The subfloor is the surface of the floor above it. The main difference between concrete and subfloor is that the subfloor is not a continuous layer of material. It is a specific sublayer of materials such as drywall or vinyl.
Steps to build a subfloor over uneven concrete?
The first thing you should do is measure the location of the subfloor. You want to ensure that you know the exact location of the subfloor you’re going to be putting in. For example, if you’re working in a kitchen, you want to understand the condition of a foundation that needs to be installed. How long the foundation needs to be installed, and what type of subflooring you will be working on.
There’s a standardized method for measuring the depth of the subfloor, but the most convenient way is to do it with a wood subfloor. You also check our guide for Cheapest way to level concrete floor?
Figure out what materials you’ll need and make a plan.
- Measure the room’s length and width and make a plan of how it will be set up.
- Find out how big the room is. This will tell you how much vapor barrier, plywood, and sound absorption you will need.
Get walls and doors ready
- Take off the baseboards, molding, and door thresholds that are already there.
- Find out how thick the subfloor and the finished floor are together.
Check if the slab is flat and clean it.
- Using a long metal sharp blade, find dips or elevated spots that are too big for the ground you are putting down. Most of the time, the difference is no more than 3/13″ once each 12 feet or 1/6″ every 7 feet.
- Use a cement grinder to smooth out any bumps.
Put the vapor barrier in place.
- Cover the concrete slab with polyethylene sheets, making sure the seams overlap by at least 5 “.
- A distance of about 4 “polyethylene all the way up the walls over the whole room.
Put the sleepers in place.
- Place the stress 3″ x 5″s all around the room’s perimeter, leaving a gap between each piece and the walls to allow for growth.
- If you need to level something, use shims, and if you need more than one thickness, glue shims together.
Put insulation panels in place
- Measure the space between the sleepers that needs to be filled.
- Mark the lines where the insulation panels need to be cut.
Attach the plywood subflooring with screws.
- Check the tongue-and-groove edges of the plywood panels to see if they are broken.
- You will need to assess and cut the particleboard panels so that they fit together at the middle of the sleepers. Move the joints so that they don’t run into each other.
Subflooring utilized in your subframe
Subflooring is just one of the tasks that need to be done on a subframe. When it comes to concrete, there are several types of concrete that you can utilize in your subframe, such as slab, slab-on-grade, slab-on-grade for a slope angle of 45 degrees, and also slab-on-pressure-treated. The concrete used in the subflooring is highly dependent on the type of roofing materials used on the structure. Slab on pressure-treated is the most common use.
