Modern utility trenches feature multiple conduit layers carrying high-voltage lines, fiber optics, and control systems. An HDPE Duct Spacer is engineered with interlocking mechanisms, ribbing, and structural gussets to carry significant vertical and lateral loads. The robust plastic composition resists cracking under thermal expansion and contraction cycles beneath the surface. This structural stiffness guarantees that duct banks do not collapse or deform under heavy backfill pressure or traffic loading above.
