Void Filling Under Concrete Slabs St. Louis

If you have a void under your concrete, it will lead to settling and/or cracking concrete. You get a void when base soils under the concrete or shifting rebar deteriorate to the point where a hole is created underneath the concrete. When the soil settles, crumbles or is moved by ice, water or animals a gap that opens up between the soil and the bottom of the slab of concrete ends up in a loss of solid support for the slab.Once the void appears, it can be very difficult to fill yourself. While you can fill a smaller area with sand or dirt to level it, like a sidewalk, large slabs like patios and driveways require bigger solutions. They have to support but not lift the slab too far. That's why Mudjacking is the perfect solution for this problem.Mudjacking is a process of drilling 1 3/4" holes in various sections of concrete slabs to either Void Fill for stabilization or to raise to the highest point allowable. Crushed Limestone and cement are mixed together to form a grout mixture that once injected allows for proper raising and/or stabilizing under the affected concrete slabs. Once the job is complete we clean the area and refill the drilled holes with new concrete. Most jobs take a couple of hours and require water and electricity to be present when the job is being worked. 24 hours is recommended before driving on the raised slabs. It always helps the longevity of the work to either have downspouts directed away from sunken areas and/or have all expansion joints caulked (an additional bid can be given for this type of work). Water testing is done to ensure that water runs properly away from the foundation when applicable.Making sure that your concrete slabs are void-free can add to the value and durability of your home and make sure that the investment you have made in your home doesn't go to waste. Don't let cracking or buckling concrete go un-repaired.

Concrete Leveling in St. Louis, MO

Nick Gress Foundations specializes in both commercial and residential concrete leveling services for all types of concrete, including warehouses, garages, foundations, steps, streets, driveways, sidewalks, pools, patios, and concrete slabs of all kinds.

The best way to economically fix concrete is to save the existing concrete by making it a smooth, even surface. When you level a concrete slab before it becomes too damaged to be repaired, you can save money on more expensive repairs in the future and make sure that the concrete will be supporting your home and family for years. Not only is this a cost-effective way to repair concrete. it is also much faster than replacing the entire concrete slab and your downtime is very minimal.

Many issues arise from uneven concrete:

Drainage problems from runoff and puddles collecting in places it's not supposed toUnsightly concrete, decreasing your property valueSafety and tripping issues for visitors or customersHigher liability issues for home and business owners for dangerous walking areas

Concrete leveling is the process where the concrete slab is "floated" up in small sections, letting us control the lift and protecting the concrete from further damage. When you work with professionals that understand the process, they will know the right mix of equipment, materials, and labor to keep the concrete from further issues and to avoid damaging any attached or nearby buildings.

Nick Gress Foundations creates a series of one-inch diameter holes in the slab, through which we hydraulically pump a slurry with a limestone base underneath the slab. This fills in the voided areas under the slab and forces it to rise evenly, making a new base under the concrete, and solidifying the entire area.

What Is Mudjacking and Why Is It So Important

Mudjacking is the preferred technique for raising and stabilizing settled concrete slabs. Also known as slabjacking or concrete lifting, this repair method is highly effective and provides long-lasting results.

But, what exactly is mudjacking, and how does it work?

A Quick and Easy Method of Concrete Repair

Over time, concrete slabs settle as a result of changes in the underlying soils. Mudjacking addresses these changes and restores the integrity of the concrete.

It may sound complicated but it’s not. The repair process takes very little time – usually just an hour or two from start to finish (although larger projects may take slightly longer).

This concrete repair starts with drilling a few small holes in the settled concrete slabs. Next, a cement slurry is pumped through the holes. This mixture fills voids or empty areas in the soil, which works to stabilize the slab foundation.

Do you have Voided Concrete?

When the ground under a concrete slab erodes away, it can cause a lot of problems. Homes with basements usually have the most problems, but voids can impact driveways, patios, sidewalks, and more. The erosion causes air pockets or voids to develop under the concrete slab, taking support away from the surface.

Causes of Voids

There are several different reasons that a void can occur beneath your concrete. Most of the time, it isn’t due to erosion, but other factors. Some issues are fast, others can take years to cause problems.

Soil consolidation occurs over time. This occurs when loose soil under the concrete consolidates or sifts down. If the soil is not properly prepared by being tamped down, this can occur. When the soil consolidates, a void can form over time.

Settlement is a natural occurrence that happens over time. It can occur with new construction or with a property that is a hundred years old. It all depends on the type of soil and weather patterns. Heavy rains or flooding can cause the soil to settle faster than normal. If the settling soil is in a large enough area, it can allow erosion to occur. Settling soil sets the table for a problem, erosion just makes it worse.

What Is Mudjacking?

You know how unsafe and unsightly uneven or sunken concrete can be. Water erosion, poor soil stability, tree roots, and earthquakes are some of the causes of sinking or uneven concrete. When concrete settles or sinks, it can also negatively affect the curb appeal of your home. It is possible to quickly and easily repair it using a process called mud jacking. Mud jacking is effective for raising concrete on porches, decks, patios, walkways, basement and garage floors, and driveways.

Mud jacking, also known as slab jacking, concrete lifting, and slab leveling, is an easy and inexpensive technique that is perfect for fixing certain settlement issues with your concrete. It is the process of lifting concrete slabs that have settled by drilling holes through them. Then a mixture of water, soil, sand, and cement called mud or slurry is pumped beneath the settling slab to lift it. The mixture cures to create a solid, stable fill that stabilizes the slab back to its original location.

When used to repair a settling home foundation, mud jacking is a professional job that requires using special equipment. All work should be done by a trained contractor, like the experienced staff you’ll meet at Perma-Pier, who has expert knowledge of local soil conditions and their requirements.

Mud jacking has two primary applications for repairing a foundation:

Fill Voids: Foundation problems are usually caused by the perimeter of the foundation settling. A foundation contractor will level settled sections of a foundation with push piers. When the piers are installed under the perimeter grade beam and the foundation is raised, it creates a void under the slab. Mud jacking fills the empty space beneath the footing created by this lifting. The foundation contractor uses mud jacking to fill this void by drilling 2″ holes through the perimeter grade beam and pumping a mixture of soil/cement mud into the void.Raising Interior Floors: Sometimes the interior portion of the slab foundation settles. Mud jacking is one method used to return the interior floors to their original position. Mud jacking to raise interior floors is done using the same process: drilling 2″ holes through the slab in the areas that have settled and pumping a mixture of slurry underneath the concrete, lifting the slab back to position.

There are several benefits to using the mud jacking process:
