Mudjacking is a process of lifting up the sunken slabs by pumping a mixture of water, sand, mud, and cement underneath. It can raise concrete floors on walkways, driveways, decks, and basement or fill-up a void below the slab to avoid further sinking.

A pump is used to fill up the void through the drilled holes on the sunken area and raise back a concrete slab to its original position. Every homeowner should examine the pros and cons of mudjacking before hiring a professional contractor for any concrete lifting.

 

Pros:

1. Affordable process: Compared to the cost of replacing the concrete slab, mudjacking is cheaper. It only costs you about a third of the cost of concrete slab replacement.

2. Quick process: This technique is one of the fast method to repair slab since the mixture of sand, cement, and water can take a day or two to repair concrete slab sinking issues.

3. No further damage: Mudjacking injection ensures there is no damage to your lawn by filling the voids under the structure. The injected concentrated quantities fill the cavities and raise the slab in the sunken area to avoid more cracks or damage.

4. Effective: The procedure can be done at any time regardless of the weather conditions. You can walk and drive on the surface the same day after the repairs without any effect.

5. Preserves the landscape: The procedure doesn’t result in a construction zone or let you worry about the demolition of the concrete floor. The floor remains intact as well as your landscape.

6. Environmentally friendly materials: The injection slurry is made from naturally available materials which are environmentally friendly.

7. Not messy: It is not messy or noisy to slab jack or fill-out a sinking area. If you’re replacing the slab, you have to jack ham and haul it away which is noisy, tedious, and messy.

8. Familiar process: Slabjacking has been in use for many years and all foundation repair companies are familiar with the procedure.

9. Matching concrete: The concrete will remain the same in color and texture with the surrounding concrete.

10. Cheap equipment: Mudjacking equipment is relatively cheap compared to polyurethane equipment and materials.

 

Cons:

1. Cause soil compression: The injected material is extremely heavy leading to soil compression beneath the slap. This may cause more sinking on the foundation slab.

2. Short-term procedure: Mudjacking injections is a short-term procedure which needs to be repeated more often.

3. Not the best option: It may not address the underlying condition on why the concrete is sinking, therefore, you need to find the root cause of the problem for you to come up with a long-term solution to the problem.

4. Cost of materials: The size and amount of materials needed may increase the cost of mudjacking. The quality of materials used also influence the cost. Cheapest options may not last long and may turn expensive in the long run.

5. Suitability: If the concrete floor is completely damaged or crumbling, then mudjacking will be a waste of time and money.

6. Need a professional repair: Using a non-professional contractor for mudjacking work on concrete slab foundation can cause more problems than good. Therefore, you need a professional contractor to do a great repair.

7. Holes: To fill-up the underneath areas, you have to drill holes on the concrete floor.

8. Wash out of slurry material: The slurry material can be washed out by underground water, water from pipe leaks or even poor drainage. This also leads to a weak foundation.

9. Rough texture: The slurry material is rough in texture which cannot fill-out a void underneath completely. This increases the chance of further sinking in the future.

10. Cannot fix cracks or crumbles: The process can only fix sinking concrete surfaces. If there are cracks or crumbling, other repair methods are used.
