SLAB LIFTING
T ypical Applications: • Driveways • Bridge approach slabs • Highways • Roads • Warehouse floors • Pool decks Solution: • AP Lift 430 Expansion Rate: 24x
Application Process Steps: 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 the lowest point on the 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. Lifts Slab Back to Level Height • AP Lift foam allows contractors to raise slabs to within 1/10” of the desired height.

Reinforces Eroded Areas
• Polymer foam displaces water and cures into a solid • Mass reversing the erosion process. Compacts Soil • AP Lift foam injection compacts loose soil to create a strong substrate. Fills Voids Caused by Decay • Polymer foam fills voids before it cures, making it a great solution for instances of biological decay.
• AP Lift 460
Expansion Rate: 24x Compressive Strength: 50 psi
Results: • Use of slab the same day as repair
(Lift foam cures to 90%full strength in 15 minutes) • Support ranging from 7,200 to 14,000 lbs/ sq. Ft. • Lift and/or stabilize lasting decades
