Filling a Sunken Living Room Floor to Create a Level Space

As the sunken living room floor becomes a habitual sight, it’s time to take decisive action to transform the space. To conquer this task, begin by removing the existing flooring and trim, setting the stage for a sleek makeover.

Next, reroute utility lines to accommodate the new floor level, followed by a layer of poured concrete to fill the recessed area. For a modest floor drop, consider adjusting the height of the floor joist or installing sleeper joists, essentially creating a sturdy deck-like platform to elevate the subfloor.

What Materials Would I Use to Fill in a Sunken Living Room Floor with a 3.25 Drop?

The amount of lift you need will depend on the desired floor level and the height of the drop.

You might consider using self-leveling compound, a type of cement-based material that’s specifically designed to fill in uneven surfaces. This stuff is awesome because it will spread out and level out the floor, no matter how big the drop is. You can get it in a bucket or a bag, depending on the size of the area you’re trying to fill in.

Another option is to use foam underlayment, which is a type of insulation material that can be cut to fit the shape of your floor. This stuff is super lightweight and easy to work with, and it’s great for filling in small to medium-sized drops. Just make sure you follow the manufacturer’s instructions for applying it, or you might end up with a uneven surface.

For bigger drops, you might need something a bit heavier-duty, like a concrete mix. This is a more involved process, but it’ll give you a solid, long-lasting surface that can handle heavy foot traffic. First, you’ll need to prepare the area by cleaning it and making sure it’s dry. Then, you can mix up the concrete and apply it in sections, using a trowel or a sponge to spread it out evenly.

What Type of Concrete is Best for Filling in a Sunken Living Room Floor?

If you have a sunken living room floor, you might be wondering what type of concrete is best for filling it in. It’s important to choose the right type of concrete to ensure it lasts for a long time and looks great. Here are some tips to help you choose the best concrete for your sunken living room floor.

Consider the Condition of the Floor

Before you start filling in the sunken living room floor, you need to consider the condition of the floor. Is it dry, damp, or wet? Are there any cracks or holes? Depending on the condition of the floor, you may need to prepare it before filling it in. If the floor is damp or wet, you may need to apply a waterproofing material to prevent further damage.

Choose a Strong and Durable Concrete

For a sunken living room floor, you’ll need a strong and durable concrete that can withstand heavy traffic and daily use. Choose a concrete that is specifically designed for indoor use and has a high compressive strength. You can also consider a concrete with a decorative finish, such as a texture or pattern, to give your living room a unique look.

Types of Concrete for Sunken Living Room Floors

  • Epoxy-based concrete: This type of concrete is strong and durable, and can be used on damp or wet floors.
  • Polyurethane-based concrete: This type of concrete is flexible and can be used on floors with slight cracks or imperfections.
  • Self-leveling concrete: This type of concrete is specifically designed to fill in uneven surfaces and can be used to level out a sunken living room floor.

Can I Install New Joists on Top of the Existing Floor Joists to Raise a Sunken Living Room Floor?

You might be wondering if it’s possible to add new joists on top of the existing ones to lift up a sagging living room floor. It is technically feasible, but it’s not a straightforward fix. Essentially, you need to consider the structural integrity of your home before attempting this type of renovation. The old joists might not be able-bodied enough to support new load, which could lead to further damage or even collapse of the floor.

To begin with, you’ll need to inspect the existing joists for any signs of rot, damage, or weakening. If they’re in poor condition, you might need to replace them entirely, which could make the project a lot more complicated and costly. If they’re still serviceable, you can move forward with adding new joists. The key is to ensure that the new joists are securely fastened to the old ones, forming a sturdy bond that can handle the additional weight and stress.

Another crucial factor to consider is the installation of a subfloor, which will provide a solid foundation for the new joists. This involves laying down a layer of plywood or oriented strand board (OSB) to create a flat, even surface. This will help distribute the weight evenly and prevent any new sagging or warping.

It’s also essential to consult with a professional, like a contractor or structural engineer, to determine the feasibility of this project and ensure that it’s done safely and correctly. They’ll be able to assess the situation and provide guidance on the best course of action. With the right approach and expertise, installing new joists on top of existing ones can be an effective way to raise a sunken living room floor and restore it to its former glory.

How Do I Determine the Best Way to Raise a Sunken Living Room Floor?

Is your living room floor lower than the rest of the house? Don’t worry, raising it is a feasible task. Before you start, it’s essential to assess the situation and plan your approach. Here’s a step-by-step guide to help you achieve the desired outcome.

Assess the Situation

  • Check the floor level: Measure the sunken area to determine the depth of the floor.
  • Identify the cause: Determine why the floor sank in the first place. Was it due to soil settlement or water damage?
  • Clear the room: Move furniture, rugs, and other items out of the room to give you a clear working space.
  • Protect the surrounding areas: Cover the surrounding walls, baseboards, and any remaining flooring with drop cloths or plastic sheets to prevent damage from debris and dust.

Raising the Floor

  1. Jack and Pump Method : Use a hydraulic floor jacking system to lift the sunken floor. This method is suitable for small to medium-sized areas.
    • Place hydraulic jacks under the floor and slowly lift it to the desired level.
    • Use shims or wedges to support the lifted floor and prevent it from collapsing.
  2. Excavation Method : Excavate the area by digging a trench around the sunken section. Then, pour new concrete or install a new subfloor.
    • Remove the old subfloor and any damaged materials.
    • Compact the soil beneath the floor to ensure stability.

Finishing Touches

  • Level the floor: Check the floor level to ensure it’s even and smooth.
  • Install new flooring: Place new flooring material, such as tile, carpet, or hardwood.
  • Finish with trim and molding: Add baseboards, trim, and molding to complete the look.

Remember to always follow safety guidelines when working on your home. If you’re unsure about any part of the process, consider consulting a professional. With the right approach, you can successfully raise your sunken living room floor and enjoy a brighter, more spacious space.
