Slab Jacking vs. Replacing Concrete

So, you have a sunken concrete slab that could be repaired via replacement or lifting. How do you know which option to choose? Here are a few things to think about.

Raising Concrete is More Cost Efficient Than Replacing

If the slab is in good shape, and is of a reasonable enough size and thickness, it is usually going to be more cost effective to lift it back into place with structural polyurethane foam. The PMC pumps we use can deliver the AP Lift series of foams we use as far as 400 feet away through heated hoses. And remember, whenever you have new concrete installed, you have to haul away old concrete.

More Environmentally Friendly with Polyurethane Concrete Lifting

Everybody wants to be green and take care of the environment these days, because it’s the right thing to do. There is an environmental impact every time concrete is replaced. The cement manufacturing process is the second largest cause of greenhouse gas emissions in the world. Additionally, there is the issue of what happens to old concrete once it is removed. One would like to think it is recycled, but more often than not it ends up being dumped. Hopefully that would be in a landfill, but we’ve all seen piles of concrete rubble in places where it would be considered trash or pollution. It’s worth considering. Meanwhile the AP Lift 430 and AP Lift 475 foams we use are so environmentally friendly they are NSF approved for contact with drinking water in their cured state.

Polyurethane Slab Jacking Requires Less Downtime

How long can you, as a property owner or manager, afford to have that area out of service? Consider a busy warehouse, an airport taxi way, or a bridge approach on a highway. There is an economic impact when those locations are out of service for replacement. It can be a couple days before new concrete is traffic ready. Wouldn’t it be better to have it lifted in a few hours, and then back in service 15 minutes after the slab jacking is done?
