The soil below any segmental retaining wall will have a significant effect on the wall’s stability. Foundation soils should be inspected by the on-site soils engineer to ensure they meet or exceed design soil parameters. A geotechnical report should include parameters and recommendations for sub-soils. If poor soils are encountered during construction, consult with the owner and geotech for removal and replacement recommendations. For more information on soil preparation consult section 3.1 Foundation Soils in the AllanBlock Spec Book. (ref. BP, Chapter 2.2)
Allan Block is working to achieve our industry initiative of Zero Wall Failures. With our Best Practices Manual and experience in the industry we are trying to expand the knowledge base for the design of segmental retaining walls (SRW's) by communicating and educating the professionals in the industry.
