TERRE BOX™ PRECAST BOX WITH WATERTIGHT JOINT SEAL SYSTEM
Terre Box™ is a precast concrete box that utilizes a patented watertight joint seal system that has been certified to 20 psi hydrostatic pressure.
Terre Box™ does not require a liner to create a watertight installation. The watertight joint seal system combines post-tensioning with pressure injection of grout into the annular joint space to create a watertight monolithic structure.
Terre Box™ can be designed to solve any site condition. Terre Box™ is HS-20 load rated, without the need for a minimum cover. This load rating can be increased to meet any use requirements.
Terre Box™ is a precast solution for Brownfields development; limestone or karst subsurface geology or where stormwater runoff must be detained or retained due to insufficient infiltration permeability.
Terre Box™ is a manufactured treatment device-best management practice (MTD-BMP) used for post-construction stormwater management.
Terre Hill Stormwater Systems recommends pretreatment of stormwater runoff prior to entry into any subsurface structure to maintain the long term useful life optimum functionality of the underground structure.
