Frequently Asked Questions
What is the difference between Mud jacking, Sand jacking, Foam jacking, and A-1 Concrete Leveling?
- Sand jacking: Slabs are mechicanally raised with jacks, pipes, bars and holes are drilled in the slabs to attach lifting apparatus and then more holes are drilled to fill the voids after the slabs are raised. A dry sand mix is used and dry material can not be packed without the use of water. This material can be easily washed a way. This process can be very dusty at times.
- Foam jacking: This is a more expensive way to raise the concrete and it may leave a various different kinds of chemicals in your yard. Due to the expanding foam it becomes very difficult to control a very small lift. This may also leave voids for water and critters to get in. This also has a tendency to crack the slabs as they are not completely supported during the process of raising and leave some not completely even when it is finished.
- Mud jacking or Slab jacking: generally in a portable pump which is carried to the location of area to be raised. A hole up to 3” inches in diameter drilled into the concrete that can weaken the area and allow too much material to flow to quickly causing cracking of the slabs. Varying combinations of soil, sand or other materials may be used.
- A-1 Concrete Leveling: Using techniques that utilize a 1” inch hole about the size of a quarter to avoid weakening the slab or raising the slab to quickly. A pulverized Limestone is used that is denser than your soil. This is mixed with water and uses the weight of the concrete to maximize the compaction as it is raised. This can be pumped slowly and safely through hoses that connected directly to truck. No Chemicals, no equipment dragging just our feet and safe limestone for the environment.
Will the holes used in leveling be dramatically different in color compared to our existing cement?
We do have ways of matching the color depending on the color of the concrete. It is virtually impossible to match the color of existing concrete. Over time due to weathering it will start to blend with existing concrete.
How long has A-1 Concrete Leveling been in existence?
Mud jacking or slab jacking has been commonly used for about 50 years. Refinement of the process to its current state occurred about 20 years ago by an inventor from Peninsula, Ohio. This franchise in Minnesota started in the year 2000 which is family owned and operated with no employees.
- A-1 has the local ownership with expertise and support of a national franchise
- A-1 uses smaller holes
- A-1 has exemplary record of honoring warranties
- A-1 is fully insured
- A-1 uses the state of the art equipment
- A-1 belongs to the Better Business Bureau, 2 Builders Associations, Seven Star Contractors and a Chamber of Commerce
How do we figure our bidding process and what is included?
The bid was done in the following factors in mind: Voids or filling to be done before raising, difficulty of raising, cleaning the joints ( sawing), formation of the concrete, (curves, sections, floors, porches, etc) access to the work area, (distance, trees, bushes, backyard, etc), thickness of the concrete slabs, and what the finished product will look like. The bid also includes fuel, materials, usage wear of the equipment, labor, and insurance.
How long will Concrete Leveling last?Although every situation is unique. Concrete usually sinks because of water erosion and compaction of the soils. Our pulverized limestone dramatically
improves the compaction of the soils. Sometimes high levels of organic materials maybe difficult to stabilize for long periods of time. Improper drainage, misaligned or broken pipes, or newly installed utilities, or surface cracks may allow water to undermine the soils underneath. Some circumstances are that slabs maybe suspended or have a large capacity void underneath them. Then when the concrete is filled and lifted, the soils sometimes have never had any weight on them. This may cause them to resettle due to compaction that has taken place. We ask that you call us back and we go back in the same holes and repump it for free.
Carefully compare bids and beware of Con Artists
Keep in mind that the lowest bid may not be necessarily the best bid and that an unusually low bid maybe a cause for an alarm. The bid may not be a firm bid or include the cost of Labor, fuel, materials, trip charge, hidden voids during the bid, and maybe using a inexperienced crew. It may be a low bid to get the work and finish high due to unwarranted line of excuses. Can provide only a P.O. Box address, requires a full or substantial payment before work begins, uses high pressure sales tactics, and does not belong to any organizations or associations to have business track record of doing business.
