Trench boxes provide essential worker safety when installing pipe in deep trenches or unstable soils. However, their use with large diameter flexible pipes presents a critical challenge: maintaining compacted embedment integrity during trench box movement. Improper technique can create voids alongside the pipe or reduce backfill density adjacent to the pipe, eliminating the lateral support that flexible pipes require to control deflection.

In the realm of construction products, an ongoing discussion among engineers, contractors, and project partners often centers around the strength of different materials. Traditionally, strength has been associated with products that remain rigid and unyielding under load, such as reinforced concrete walls or heavy steel beams.
