Uneven Raised Basement & Concrete Floor

Basement floors can become uneven when they begin to dip and sag. It could be a sign that your foundation is in distress. Settling and shifting of the foundation often cause the floors to become uneven. You can easily understand whether your floor is uneven or not by rolling your child’s toys across the floor without pushing them. If it moves on its own, your foundation is likely dipping or sagging. Read on to discover the issues plaguing your uneven raised basement concrete floors.

How to Raise Uneven Basement Concrete Floor

Before you move forward, you may need to investigate why the concrete is uneven. It would be best if you figured whether it’s settling due to the shifting or settling of the foundation or any other issues. If your foundation is shifting, it may even be lifting the concrete floor as it moves. Whatever the causes may be, our Crossroads Foundation experts will conduct an in-depth analysis of your concrete floor and identify the issues you want to fix.

Planning for Uneven Raised Basement Concrete Floor Project

First of all, you need to have a plan before you get started with the project. It would help if you decided whether you want to apply concrete or any other materials. 

The degree of accuracy in leveling your concrete depends on which flooring material you choose. 

How to Level an Uneven Concrete Floor

Get started by removing anything and everything from the site, including furniture, baseboard, and debris on the floor. Vacuum the area to remove any dirt and dust. 

Be sure to thoroughly clean the concrete floor to ensure a tight bond between any leveling agent and the porous concrete surface. Dish soap and commercial cleaners work best to remove dirt and grime. But shot-blasting is the best option when it comes to years’ worth of caked-on grease or other stubborn stains. 

Leveling Concrete

For leveling concrete, there are a wide variety of options available. Some opt for self-leveling concrete; others utilize mud jacking. The polymer-modified cement flows easier than traditional concrete and can typically flatten concrete slabs for self-leveling. However, it’s not as durable as solid concrete. 

Sometimes, an uneven concrete floor points to foundation failure. In such cases, it’s best to contact a concrete raising company. Our Crossroads Foundation team uses specialized equipment to pump a slurry mixture below the slab, fill any voids, and raise it to a stable position.
