Certified Retaining Walls

The Final Engineering Stamp Certifies Retaining Walls

As it certifies new or replacement retaining walls were built in accordance with the engineer’s plan from start to finish, property owners have no legal recourse without a final engineering stamp should premature failure or collapse occur.

To Earn the Final Stamp by a Licensed Structural / Civil Engineer

  1. On-location site visit where wall is being built or replaced
  2. Retaining wall design plan with engineer’s official stamp
  3. Footing inspection certification stamp
  4. At least one inspection during construction (more are required for larger walls)
  5. Final Inspection stamp to certify the retaining wall

Procuring these engineering stamps in the above order is the consumer’s only legal protection.

Site Inspection Stamp Procedure

The engineering site inspection stamp procedure begins with the first stamp issued upon passing the retaining wall footing inspection. The engineer must be on site to pressure test the soil and visually confirm the footing will support the weight and hydrostatic pressure the retaining wall must withstand. Pressure testing is crucial because if the retaining wall footing is not built on solid ground with compactible dirt the wall will sink and fail. The quality of the footing dirt is especially important when replacing crosstie or timber walls where poor quality dirt, also known as silt, remains. The footing is the foundation of the entire structure, so it must be perfectly level with all the other retaining wall specifications as set forth in the engineering plan.

Throughout the construction process of the retaining wall are several stages which also require site visits and testing earning additional stamps by the engineer. Without inspection stamps for each stage in the proper sequence by the engineer who designed the plan of the retaining wall no final or certification stamp will be issued. City and county engineers will also refuse to inspect or test the integrity of the wall without first verifying the wall’s designer has certified it.

The First Step

The first step for any new or replacement retaining wall at least three feet in height (above ground level) is the engineer’s plan. The engineer will determine what retaining wall materials the HOA and the city or county will approve.
