5 Benefits of Leveling Concrete Using Sandjacking
Do you know how to level a concrete floor or slab? Try jacking it!
“Jacking” in general means lifting — especially as it applies to concrete leveling projects. Types of concrete jacking include mudjacking, limestone grout leveling, and expanding structural foam leveling.
In this article, we focus on sandjacking, the process of lifting concrete, and filling in the void underneath with compacted sand. It is often seen as a convenient and inexpensive way of leveling concrete slabs.
Benefits of Sandjacking Over Similar Concrete-Leveling Techniques
The “sand” in sandjacking most often comes from limestone — which has excellent properties for this purpose. Of course, you also need the right concrete-leveling tools (e.g., a concrete floor leveler) to do the job right.
Here are some benefits.
1. Limestone Is Non-Toxic
Polyurethane is a popular polymer ingredient used when mudjacking soil or sand. Its self-leveling concrete properties allow it to expand throughout an entire enclosed space. However, this polymer can release harmful fumes.
Limestone is an all-natural material and a good concrete floor leveler. It comes straight from the earth and is returned to the natural environment through the sandjacking process.
2. Sandjacking Costs Less Than Other Concrete Leveling Methods
Sandjacking costs from three to eight dollars per square foot, based on the average listed by home repair sites. Other concrete leveling and repair processes cost more.
The cost also depends on the composition of the slurry. Here, “slurry” refers to a semi-liquid mixture containing fine particles suspended in water and meant to thicken or solidify.
3. Limestone Sand Adds Less Weight to the Base
If you know how to level a concrete slab, it’s not that much harder to learn how to level a concrete floor. Be careful, though. Limestone sand, like any material, does add some weight.
The larger the area, the greater the weight.
As a sedimentary rock, limestone is highly porous and readily absorbs liquids, making it ideal for sandjacking. Even so, it weighs approximately 150 pounds per cubic foot. So be sparing when introducing moisture.
4. Sandjacking Lasts Longer Than Traditional Mudjacking
Let’s face it — mudjacking is past its prime. Suppose a foundation is built to stabilize an entire home, but it can’t maintain its shape or structural integrity when the ground below it settles and no longer provides good support.
This can happen when the soil is poorly packed or has absorbed too much moisture. With time, the soil expands and contracts, making the concrete buckle or even collapse.
5. When Done Right Sandjacking Leads to Good Compaction
This is where the properties of limestone sand are helpful. Its two percent moisture results in a 95-99% compaction rating.
As a good concrete floor leveler, limestone sand can stabilize the concrete rather than let it get damaged by nature’s forces. Although many companies claim that the sand they put underneath a sunken slab is compacted, they don’t use moisture to finish the project. The sand can’t be fully compacted without moisture.
We Reduce the Level of Your Concern
When leveling a concrete slab, whether it’s a single sidewalk paver or a home’s slab foundation, you need to choose the right method. While there are many concrete leveling techniques, they are not equal.
We believe sandjacking is the best and most effective support for sinking concrete slabs. Our patented Sandjacking™ process is comparable in cost yet superior to mudjacking in results. It is well below the cost to replace concrete.
