Before constructing any segmental retaining wall, the on-site soils engineer must verify and document that soils meet characteristics specified in the soils report and wall design. Soil types vary tremendously in their response to water and effects on retaining walls. Minimum infill soils need to meet requirements outlined in Section 1 Part 2.3 in the Allan Block Spec Book. (ref. BP, Chapter 2.5)
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.
