How-to Build a Reinforced Retaining Wall

Yes, I need stamped engineering, now what?

1. Determine the area of construction and type of wall. Go to the Download Pros Guide page and select the HTS guide based on the block you will be using.
2. Download and print the "Request for Stamped Engineering Form" and fill out the general information.
3. If there will be a slope at the top of the wall or bottom of wall, use the "Slope Angle Determination Guidelines". (Found in SECTION 1: PLANNING.)
4. Take photos of the retaining wall area.
5. Sketch a plan of the project using the "Sketching Instruction" and graph paper. (Found in SECTION 1: PLANNING.) Professional plans/prints should be used if available. Here is a checklist of what your local building department may be looking for in your plan.
6. For soil information, you will need a recent soil report or to collect a soil sampling (directions can be found in SECTION1: PLANNING).
7. Put your plan sketch, photos, soil report/sample and completed "Request for Stamped Engineering Form" in the mail to HTS or when possible, email electronically (contact info is on request form or online).
8. Once received, a HTS representative will contact you. Cost for stamped engineering is $495 per location (can have multiple walls). Turnaround time is approximately 5 days after ALL materials have been received and approved. After you receive everything, you can proceed to building a retaining wall.
