OT: slab jacking with grout.

Slab Jacking with Grout

The user wants to raise a 14'x14'x4" floating shed slab 2" on one side and is considering DIY methods due to high professional costs ($750/hr). They have a friend who makes sausage stuffers using PVC pipe and water pressure, inspiring a similar approach for grout pumping. The user already has some materials and believes they can accomplish the task for under $100. They are seeking advice or similar experiences.

Considerations and Advice

One suggestion is to start with a small-scale experiment using a miniature grout pump on a paver to identify potential problems. The speed of grout setting and control over slab lifting are also raised as concerns. It's important to consider what caused the slab to sink in the first place and whether the slab has broken or cracked. The type of grout to use is also discussed, with suggestions for chemical retarders and varying grout stiffness for lifting versus filling voids.

Alternative Solutions and Experiences

One user mentioned a neighbor's driveway being slab-jacked and the original poster's frustration with a contractor who wouldn't do their shed. Another user suggested Techno Metal Post and Helical Piles as an alternative. Another user suggested using SPEED CRETE to fill in the sinking concrete.
