DURASKIRT™ Impact Backfill Load Testing

Yes, we have tested DURASKIRT™ panels for strength against backfilling. We are confident that you will be pleasantly surprised by the results. Although we were aware that we had created a very strong panel, the engineering calculations confirmed its superior strength and even amazed us. Now, without further ado, the following results demonstrate why DURASKIRT™ & SDG™ panels are the very best compared to every other option and why you should not hesitate to make it your choice as well.

The Construction Process of Our Concrete Panels

DURASKIRT™ & SDG™ concrete panels are designed for use around the base of buildings. This is where materials must be made to withstand the toughest conditions. Therefore, the materials we use greatly exceed the requirements for all forms of weather conditions. DURASKIRT™ & SDG™ panels perform against, landscape chemicals, most acid and alkaline soils, and are constructed for ground contact and ground burial in mind. Yes, in these conditions, although harsh, the panels may experience soil pressures or loads. In fact, we had them tested and the following results astounded us.

PROVEN: DURASKIRT™ at 30″ of backfill is 11.7 times stronger than the minimum strength needed to support the impact.

Load Testing Results

After conducting a load test, we proved DURASKIRT™ provides sufficient evidence that it will support the loads as intended. The following calculations indicate it is over ten times stronger than the maximum lateral loading from the backfill on the panel. For this reason, DURASKIRT, LLC supports the DURASKIRT™ PRO24, PRO30, PRO33, and PRO37 panels, as well as the PRONF24, PRONF3037, and PRONF3337 products for backfilling. Please follow the installation instructions carefully for each product to ensure proper backfilling support.

Engineers Report:

Although DURASKIRT™ panel heights range from 24″ to 37″, the drawings below present the load calculations for the DURASKIRT™ panel at 30″ backfill. This test was conducted to demonstrate the strength sufficiency of the DURASKIRT™ panels under backfill pressures. Furthermore, it was treated like a reinforced retaining wall using the equivalent fluid pressure for the soil (measured) and the strength values of the reinforcement and the concrete mix based on the manufacturer’s specifications.
