When an underground system is built, there can be areas where personnel entry is not required for installing or servicing electrical or communications wiring. Handholes serve as space to assist the cable to pass through ducts smoothly, almost like an underground vault. The size of the handholds for telecom cables is smaller than that of manholes. They also have a detachable cover, allowing for easy access to the conduit system.
Junctions such as handholes can be weak points in a system, meaning they need to be made from sturdy materials that can stand up to the destructive effects of weather, pressure, and time. Our handholes can be built using precast concrete polymer. This is a popular product in the construction industry for structural components. Where traditional concrete uses cement as a bonding agent, polymer concrete uses polyethylene, resins, and other polymers. This creates a concrete that is resistant to corrosion and extreme temperatures. Polymer concrete can be manufactured with thinner materials, which saves on weight without compromising on strength. Lower weight is easier to ship and makes installation at the job site much easier.
