All The Walls’ proprietary Stresswall™ services are backed with over 30 years of experience and our proprietary Stresswall™ technology. Stresswall™ services include design and engineering consulting for permanent cost-effective pre-stressed/post-tensioned pre-cast retaining walls and seawalls.
Stresswall™ services include design and engineering consulting for a counterfort/panel wall technology that is a cost effective solution that results in a permanent retaining wall. We will work with you to design a counterfort/panel wall system using the Stresswall™ technology that will provide you with a long-term, cost effective solution that will meet your needs.
A preliminary concept similar to the current Stresswall™ technology was originally developed in conjunction with Morrison Knudsen engineering. CDOT, in the early 70’s, was planning for the extension of I 70 west from Idaho Springs to Glenwood Springs Colorado. Due to the short construction season at elevations over 7,000 feet CDOT felt that a precast retaining wall option would be the optimum solution. The result was a combination of mildly reinforced precast L-shaped counterforts with precast parabolic panels placed between adjacent counterforts.
This forerunner to walls using the Stresswall™ technology utilized parabolic 1 meter high wall panels so the panel reinforcement was at a minimum because the resolved earth loads on the panels resulted in a compressive load being transferred to the counterforts. Therefore, no tension cracks would develop or propagate in the panels as would have been the case for flat panels. Walls designed using the Stresswall™ technology can use panels with varying cross sections including rectangular section prestressed panels in combination with post tensioned counterforts to maximize the load capacity of the counterfort /panels assemblies. Accordingly all of the potential tensile load points of the counterfort/panel assembly has an induced compressive load to prevent tension cracks.
The result are permanent wall structures utilizing the Stresswall™ technology!
