Rainwater tank TERRE ARCH™

water storagein-groundprecast concrete

Terre Arch is a modular, multi-chambered, precast concrete stormwater storage system engineered for underground installation. Terre Arch’s strength, storage capacity, and fast installation make it the most economical concrete system available. Terre Arch is a modular, multi-chambered, precast concrete stormwater storage system that is engineered especially for underground installation. Terre Arch utilizes a proven arch design to provide a simple solution for stormwater detention and infiltration. Terre Arch’s patented, fiber-reinforced design is lightweight, yet incredibly strong. With a load-bearing rating of HS-25 (with 12” cover from the top of the arch to final grade), each section can support heavy gross weight trucks and machinery, allowing installation equipment direct access to the site during installation, dramatically reducing installation time and labor. Because little cover is required, Terre Arch is the best solution when the site engineer is faced with site restrictions such as high ground water tables and minimum separation between the top of the underground structure and the finished grade. Each Terre Arch installs quickly, adding several hundred cubic feet of storage in a matter of minutes. 100+ year design life Lightweight fiber reinforced concrete Minimum 5,000 psi compressive strength HS-25 load rating No concrete foundation required 12” minimum cover above arch Simple and fast installation; install 30,000 - 50,000 cubic feet of storage per day Provides maintenance access to individual chambered rows Less cover required compared to plastic chambers
