Everything You Need to Know About Slab Jacking

When your home foundation starts failing, there are several repair solutions, depending on the severity of the damage. Slab jacking, also known as mud jacking or concrete raising, is one of them.

What is slab jacking?

Slab jacking is a cost-effective repair method for sinking or settling residential concrete foundations. Below, we share everything you need to know about this method by answering some frequently asked questions about slab jacking. Let's start with the most basic question: how does it work?

How does slab jacking work?

Slab jacking is a technique to lift and level concrete slabs. Workers use a mixture of cement, water, and aggregates to add volume underneath. The contractor then drills small holes into the concrete to pump the mixture into the ground. The injected mixture fills the void under the ground and raises the slab to level it. The final step is to secure the slab, fill the drilled holes with the same mixture, and add additional support.

What causes the foundation to sink or settle?

Most of the time, the sinking or settling of your foundation is inevitable, especially for old houses. Natural changes in the soil, such as erosion, groundwater infiltration, or overgrown tree roots, can trigger this problem. Other causes of this foundation issue, such as poor soil compaction, drainage problems, and lack of maintenance, are preventable.

Is slab jacking applicable to all foundation issues?

Slab jacking is one of the most effective foundation repair solutions out there. The method is specifically for the repair of concrete slabs used for driveways, sidewalks, patios, and garages. The technique can also repair a residential foundation built on a concrete slab. However, slab jacking is not the right solution for properties that have crawl spaces or basements. A foundation specialist can conduct an inspection to identify the problem and the corresponding repair method.

How long does a slab jacking procedure take?

A slab jacking project typically takes a few hours, depending on the size of the slab. It will also depend on the number of areas that need repairs. The mixture also takes a few days to cure before the area is ready for use. Once done, expect your newly levelled concrete to last for several decades with proper maintenance.

Is slab jacking more expensive than foundation repair techniques

Yes, slab jacking is one of the most cost-effective solutions. The process only takes a fraction of the time of other techniques. The method is also non-invasive as it doesn't involve digging up and removing the existing slab. With slab jacking, you won't have to pay more to replace your existing slab. As emphasised, proper maintenance can help you and your family enjoy this newly revived space for decades.
