What Is Pressure Grouting for Foundation Repair?
Pressure grouting (the cementitious or the polyurethane injected — the voids filled, the soil densified, the slab lifted) repairs the settlement (the mudjacking — the slab's; the compaction grouting — the loose soils'; the permeation — the water's). The repair: the diagnosis (the cause — the settlement's), the method's (the matching), and the verification (the lift — the monitored; the density — the proven). The foundation's injection — the cause addressed, not just the symptom.

The methods
Mudjacking (the slurry — the slab's lifting; the voids' filling), polyurethane (the foam — the expanding; the lightweight; the precise), compaction grouting (the stiff — the displacement; the densification), and permeation (the chemical — the water's cutoff; the soil's).
Diagnosis first
The cause (the consolidation — the soils'; the erosion — the water's; the fill — the uncompacted), the investigation (the borings — the soils'; the survey — the monitoring), and the matching (the method — the cause's; the slab's vs. the deep's). The grouting treats the symptom — the drainage treats the cause.
Execution and verification
The injection (the pattern — the grid's; the pressure — the monitored), the lift (the slab's — the survey's; the gradual), the verification (the density — the testing; the lift — the tolerance), and the warranty (the contractor's — the terms). The pressure grouting is the repair's — the diagnosis preceding the injection.
The bottom line
Match pressure grouting method to cause (mudjacking/polyurethane for slabs, compaction grouting for loose soils, permeation for water cutoff) — diagnose first, monitor lift, verify density.
