Did you know that even the ancient Romans used concrete in their construction? They valued it for its strength and for its ability to be molded into different forms. They formed concrete from volcanic ash and lime, which were a bit different from the materials used today, but the substance was very similar and used for similar purposes. Today, concrete contractors carry on the ancient Roman tradition, making everything from patios to counter tops from concrete. These creations last for years and require little maintenance. We think concrete is amazing, and we hope you'll share that opinion after reading the articles provided here.
Whether it's the concrete floor in your basement, your garage, or even a driveway or patio, uneven concrete can be a major issue. Indoors, a concrete floor that isn't level or has sunk can throw doors and walls out of square, which can eventually cause cracks and damages in your walls. In the garage, an uneven floor can affect your garage door, making it impossible to open or close. Concrete floors inside and out are also more likely to crack and pull apart if they aren't properly leveled. Fortunately, there are a few options for fixing the problem.
1. Leveling Compound
The use of a leveling compound is only suitable after it has been verified that the floor will not be settling any further so that there are no worries of additional sinking, raising, or cracking. A leveling compound consists of polymers mixed with concrete, which allows it to flow smoothly and self-level. Before it can be used, any cracks must first be filled and patched. Then, the compound is poured onto the floor and spread so that all of the old concrete surface is covered. Then, the compound is left to flow until it self levels. Once it cures, you have a resurfaced and level floor. This method may not be suitable if the floor has an integrated slope toward a drain, such as in a garage.
Most concrete shifts out of level due to pockets that form beneath the slab, which may form due to an unstable base or from a washout beneath the floor. Part of the floor sinks into the void, and the opposite side may lift in response. The contractor will drill small holes through the concrete slab. They will then pump a high-density polyurethane foam into the holes. The foam fills the void and lifts the slab until it is leveled. Finally, the small holes are patched. This method is suitable for most floors, particularly those where you want the most unobtrusive holes possible.
Mudjacking is a similar process to polyjacking, except a slurry of concrete is injected into the holes in order to fill the void and lift the slab. The holes necessary for mudjacking are larger, so this method is best used in areas where the necessary patches won't cause any aesthetic concerns. Mudjacking also allows for a greater lift than polyjacking, so it may be the better choice for floors that are extremely out of level.
