AGATETEC ENGINEERING CONSULTANT conducted a detailed inspection and structural assessment of a distressed Mechanically Stabilized Earth (MSE) wall at a residential complex project in Calgary. The wall exhibited significant vertical cracking and outward bulging, prompting concerns about long-term stability and safety. AGATETEC carried out an on-site evaluation, documenting crack patterns, assessing wall alignment, and performing soil classification at the wall base. A review of the design drawings and construction practices revealed likely causes, including insufficient drainage behind the wall, poorly compacted backfill, and potential overstressing due to water pressure buildup. Temporary monitoring points were installed to track ongoing movement while a full repair strategy was developed.

Based on the analysis, AGATETEC implemented a corrective plan to restore the wall’s structural integrity and prevent further damage. The team introduced new drainage features, including additional weep holes and vertical gravel drains, to relieve hydrostatic pressure behind the wall. Damaged sections were repaired using structural epoxy injection, and carbon fiber reinforcement was applied to strengthen critical areas. Backfill in compromised zones was excavated and properly re-compacted to restore uniform pressure distribution. Post-repair monitoring confirmed that the wall had stabilized, and the implemented measures effectively addressed both the geotechnical and structural deficiencies within the residential complex site.
