Description- The residential custom home with settlement of the front porch slab and overlaid brick paving system. Also, the interior crawl space and exterior porch foundation wall have settlement and distress. A settlement of up to 1 ½” occurred at the existing porch slab and paving system due to the compression of sub soils.

Solution- Slab Jacking

Foundation Walls
The foundation was stabilized with Magnum 3” steel piers with heavy-duty Magnum angle brackets. Three (3) total piers were required.

• Average depth: 30’ deep
• Ultimate capacity: 28 Kips
• Working capacity: 14 Kips

Solution: Slab and masonry paving system
The installation of Magnum slab piers 5’ on center were utilized to transfer slab loads to proper subsoil’s.

• Magnum Piers – 7 total
• Average depth: 18’ deep
• Ultimate capacity: 3.5 kips

Slab Jacking: After the piers were in place, 81 cubic feet of cementitious grout was injected into the void. Grout was injected between the slab and sub soils to consolidate the soil, fill the voids and support the slab/paver system. A total of five working days were required to make repairs.

Results- The paving system settlement was corrected up to 1 ½” of lift, which returned the paving system to its original elevation. The above methods of repairs were less destructive and saved thousands of dollars over typical removal and replacement methods. Upon completion of this project, the owners contracted with Advanced Builders to complete masonry repairs and restoration.
