Constructing the Aquaflow ThermaPave® geothermal system

The geothermal pipes are the only difference in pavement composition from the standard Aquaflow system. This means the extra cost and alteration to the design in minimal. The pipes are simply back filled after covering with 5mm gravel.

The geothermal pipes must be heat welded together and pressure tested when installation is complete. The pipes have a lifelong guarantee of 50 years.
