Terre Arch

A pre-cast concrete modular stormwater storage system designed to either detain or infiltrate stormwater underground.

Details

Made from a fiber-reinforced concrete, this design is lightweight when compared to traditional concrete units but is incredibly strong handling live load bearing ratings up to HS-25 with a minimum of 12 inches of cover. Terre Arch is an excellent option for storing high volumes of stormwater in situations where site conditions limit the depth the system can be buried. They are installed on a stone foundation, so no concrete footings are required and when compared to plastic chamber systems require less cover to handle live loads. We offer two configurations to help with your storage needs:

  • Terre Arch 26: Is a 4 arch pre-cast concrete connected unit that provides 277cubic feet of storage and 152 square feet of infiltration area with a vertical height that is less than 3 feet.
  • Terre Arch 48: Is a 3 arch pre-cast concrete connected unit that provides 541cubic feet of storage and 160 square feet of infiltration area with a vertical height of 4’-8”.
