IGS-NA and NCMA’s Segmental Retaining Wall Best Practices Webinar IGS-NA and NCMA’s Segmental Retaining Wall Best Practices WebinarIGS North America (The North American Chapter of the International Geosynthetics Society: IGS-NA) and the National Concrete Masonry Association (NCMA) are co-hosting an October 26 webinar. The topic: Segmental Retaining Wall Best Practices. The session will be held from 1:00 – 2:30 pm (EDT) and is worth 1.5 PDHs.
Scott Vollmer, P.E. (Oldcastle) will serve as the instructor. He brings an extensive background in retaining walls and geosynthetics, and he also is an educational leader, having regularly taught NCMA’s Level 1 SRW Contractor Certification Course.


The 90-minute presentation is based on NCMA’s recently released Segmental Retaining Wall Best Practices Guide. The webinar presentation will explore best practices for design, specification, construction, and inspection for segmental retaining walls. The work in the guide and which will be presented by Vollmer is based on over 20 years of industry experience.
The takeaways for webinar participants include:

  • An understanding of the new recommendations for SRW Design and Construction
  • Familiarity with new SRW detailing options
  • Improved knowledge of material specifications for commercial SRW projects
  • Enhanced understanding of key SRW construction practices


IGS-NA, IGS, and NCMA members qualify for reduced registration fee: USD $50. The cost to non-members is USD $75.

Of the publication, NCMA writes:

This Guide reflects a compendium of contemporary knowledge collected over several decades that highlight proven solutions using segmental retaining walls (SRWs). The information and recommendations presented in this Guide are intended to augment the design practices and recommendations contained within NCMA’s Design Manual for Segmental Retaining Walls, but are equally applicable regardless of the design methodology selected. The creation of this resource was driven by the establishment of NCMA’s Zero Failures Initiative – an industry-wide program to educate owners, designers, site civil engineers, geotechnical engineers, and installers of SRW systems on the industry’s recommended practices and to promote a philosophy that strives for ensuring successful wall performance.
