The fastest method for converting a drainage ditch into an underground channel.
The Calvert Creator is a buried cover made of "high-tensile steel," which has a higher strength than conventional SS steel materials. By installing the Calvert Creator in existing ditches and paving over it with asphalt, quick and durable drainage construction can be achieved. There is also a buried cover with slits or grating called the "Slit Creator."
