Foundations can experience settlement from compressible underlying soils or lateral movements from adjacent excavations, requiring various types of rehabilitation to stop or correct the movement. Micropiles transfer foundation loads to competent bearing stratum. Compaction grouting displaces and densifies soils and can be used to raise structures. Slabjacking raises slabs by pressure filling voids with cement or expanding polyurethane grout. Jacked piers and helical piers underpin foundations and can be used to raise structures. Hayward Baker has experience with the full range of foundation rehabilitation techniques to provide effective foundation rehabilitation.
