GCD is beautifully simple in design and is easily understood. Hundreds of metres can be installed in minutes.

The duct strength enables ‘as dug’ material to be used to fill trench works. Use of AFT Trenchers has been shown to be highly effective, cutting trenches at over 8 times the speed of traditional diggers, allowing great distances of GCD to be installed with ease.
