Cementation Skanska provides Energy Piles that transport and store geothermal energy from the ground using flexible plastic pipes installed in pile reinforcement cages. The pipes are linked to a building's piping system to transfer thermal energy via heat pump for heating and cooling. The piles provide a renewable energy source and can reduce a building's carbon emissions by 50% while achieving up to 16% renewable content with no local emissions.

Cementation Skanska has undertaken
many site trials to understand the
limitations of the different Geothermal
Piling techniques with regard to pipework
installation.
Cementation Skanska are proud to be
associated with this new technique which
has created considerable interest among
clients who are environmentally aware,
and concerned with whole life costs. †
