A structure is only as good as the foundation it’s built on. And regardless of how well-constructed a structure may be, most foundations settle. That’s just a fact of life. Erosion, shifting soil, compaction, and many other environmental conditions tend to cause settling. Sometimes structures settle gradually, and in other cases they’re swallowed up in minutes. These situations create problems for property owners and opportunities for the contractors who know how to fix them.
1. Complete a thorough site evaluation
2. Saw cut joints if necessary, to release any bound slabs
3. Determine an injection point sequence, based on conditions
4. Drill the initial injection holes, starting at lowest point on slab
5. Inject AP Lift polymers in controlled short bursts
6. Monitor for lift with Zip levels, dial indicator, or laser transit
7. Observe slab for evidence of cracking or binding while lifting
8. Drill and inject additional holes as necessary to level slab

Why Does Concrete Settle?
Poor drainage, improperly placed downspouts, leaking drain pipes, and broken water lines are common culprits.
- Poor Compaction
When backfilling on a jobsite, the contractor is supposed to compact the backfill by driving over it with heavy equipment. However, this isn’t always done properly for one reason or another.
- Biological Decay
Construction trash pits, buried trees, and other biodegradable materials all break down. Sometimes structures are built over these areas.
How Does Polymer Foam Help?
- Lifts Slab Back to Level Height
AP Lift foam allows contractors to raise slabs to within 1/10” of the desired height.
- Reinforcing Eroded Areas
Polymer foam displaces water and cures into a solid mass reversing the erosion process.
- Compacting Soil
AP Lift foam injection compacts loose soil to create a strong substrate.
- Filling Voids Caused by Decay
Polymer foam fills voids before it cures, making it a great solution for instances of biological decay.
Why Are These Products Safe for the Environment?
AP Lift 430 and AP Lift 475 foam are approved for contact with drinking water (certified to NSF 61-5). That means they can be used anywhere without having an adverse effect on water quality. Having our core products rigorously tested for environmental compatibility is a key component of our committment to assuring “painless procedures” for customers.
wHAT ARE THE RESULTS?
- Use of Slab the Same Day as Repair
AP Lift foam cures to 90% full strength in 15 minutes. In most cases the site is ready for traffic right after clean up.
- Support for Up to 14,000 lbs/Sq. Ft.
The AP Lift series of polymer foams support a range of 7,200 – 14,000 pounds per square foot depending on which product you choose.
- Lift and/or Stabilization Lasting Decades
Alchemy-Spetec structural foams are stronger than crystalline bedrock.
