Slab-Lifting (slab-jacking) and Void Filling
Concrete slabs and floors that have been installed incorrectly with improperly compressed dirt can begin to sink and become uneven and unleveled.

Revolution Grout Pump
A mobile, two-component slab lifting pump that uses gear-driven technology. Unlike piston pumps, the simplicity of one continuous rotary motion means exceptional output efficiency plus less energy and wear and tear. The Revolution is a medium-pressure pump that runs on standard 110-volt power, with on-board heaters and a built-in recirculation system.

HOW TO PREVENT CONCRETE FROM BECOMING UNEVEN
For future construction projects, have your builder install granular fill such as sand or sand and gravel instead of dirt fill and make sure it is heavily compressed. Proper compaction will remove air compartment, which could settle later and cause the concrete to become uneven and sink.
