Precast
Precast manhole shafting and cones
Sections from 36 to 120 inches inside diameter: shafting, eccentric cones, and flat tops where the depth is shallow.
Cast to the standard, stenciled to prove it
Portland type V cement at 4,000 PSI, manufactured to ASTM C-478. Eccentric cones take 24 to 36 inch openings; flat tops cover the shallow structures a cone will not fit. Every piece is stenciled before it leaves the yard.
Need it lined? Armorlok cast into the pour, or Utilithane, Raven, and Warren spray systems, spark tested before it ships.
