In older pavements laid over inadequate bases or poor subgrades, slabs may settle. These can be successfully raised several inches by slabjacking. Holes are drilled through the slab at intervals, and various mixtures (oil and cement, finely ground limestone or sand, fly ash, or portland cement combined with sufficient water to permit pumping) are forced through the holes to the underside of the pavement. The consistency of the mix and the pressure to be used depend on the application. The pressure raises the slab and holds it in place until the grout hardens.  3, record 1, English, - undersealing
