WHAT IS SANDJACKING™?
Our patented Sandjacking™ process lifts settled and uneven concrete - at a fraction of the cost of replacement!
Our patented Sandjacking™ process is comparable in cost, yet superior in results to mudjacking. Compare your options or request a free estimate and we'll recommend the technology that is best for your project. Comparing bids? Don't forget to ask about the warranty.
Any combination of these methods may be used to raise your concrete
Patented Braces - no holes required!
Ideal for concrete less than 10 feet in width that can be accessed from two opposite sides. Once lifted and leveled to match the surrounding concrete, dry limestone is blown to fill the cavity beneath, providing a dry, consistent base with 95-99% compaction for the concrete to rest on.
Hydraulics & Patented Pole Jacks
When we do not have access from opposite sides, or on larger concrete slabs, we use our patented pole jacks to lift and level. After filling with our dry limestone sand, the .5 inch diameter holes are filled to match surrounding concrete as closely as possible.
Often used on large concrete slabs, such as parking lots and bridge decks, or on floors that are bordered by curbs or foundation walls where air can be "captured." As the concrete slab is raised, the dry limestone sand is pumped in under pressure to fill the air void, reestablishing a structural base. Very few holes are required for this type of repair, and they will not exceed 1 inch in diameter.
Did you know that Civil Engineers classify mudjacking as a TEMPORARY repair?
The low 2% moisture content of our crushed limestone results in a 95-99% compaction rating, uniquely allowing Advanced Sandjacking™ to offer the best warranty in the industry!
