Australian memorial: installation of Terrendis geothermal probes

[astra_breadcrumb]

Terrendis supplied 41 x 185 metre deep geothermal probes for the National Australian Memorial, a project in the Somme that was out of the ordinary

As part of a project to build the Sir John Monash Centre on the site of the National Australian Memorial in Fouilloy in the Somme, Terrendis France, a subsidiary of the Elydan Group specialising in heating and renewable energies, supplied the 41 DN 40 diameter, 185 metre deep geothermal probes. This was a sound economic, ecological and aesthetic choice for this place of reflection and amounted to a huge and unusual undertaking that called for unique logistics and military precision of organisation.

The remarkable extent of the project has provided an invaluable reference for Terrendis in the institutional sector and the development of renewable energy installations has confirmed the faith we at the RYB Group put in this activity and the support we have given it for nearly 10 years.

Weishaupt, the company responsible for installing the geothermal heat capture system, chose Terrendis probes as they are perfectly aligned with the ethos of the memorial that allies ecology, durability and aesthetics.

We looked to Terrendis because they are the only French manufacturers of geothermal probes and the company had already won us over on previous projects by the quality of their products and their expertise. Moreover, with the Terrendis probes being guaranteed for 30 years, the chosen solution yielded low energy costs for both building heating and cooling.

The European Regional Development Fund (ERDF) wanted to participate in the financing of this project to make the Memorial a reference point for promoting geothermal technology in France and Europe.

Technical prowess in the production of the probes and the drilling

To make probes of such a large size, Terrendis had to adapt its production and packaging methods. The probes were delivered on lorries carrying 4 probes on drums instead of the usual 24, a particularly complicated and unusual logistical challenge to overcome.
Weishaupt installed the geothermal heat capture system using a destructive sleeved drilling technique involving the insertion of temporary tubing into the ground to prevent collapse with a narrower tool inside it to carry out the destructive drilling.
The completion date was around Anzac Day 2018, commemorating the hundredth anniversary of the battle of Villers-Bretonneux. The site is currently being listed as a historic national site and is in the running for UNESCO recognition.

100% Made in France Geothermal Probes

Terrendis supplied the Double U DN 40, 185 metre deep geothermal probes designed to capture heat from the ground. Coolant transports the energy transmitted by the ground via the vertical geothermal probe which is then used by a thermodynamic system (or heat pump) to heat and cool the building.
The probes are made of PE 100 RC type PEHD1 and comply with the NFX 10960 standard. The Terrendis probes are entirely manufactured and tested in France at the Saint-Étienne-de-Saint-Geoirs factory.

An ecological choice

As part of its drive to reduce greenhouse gas emissions, Elydan, through its Terrendis® brand, offers products that look after the environment and combat energy wastage, with quality standards that are amongst the most exacting on the market. Pre-insulated flexible pipe solutions can be used to replace or complement older, more rigid solutions such as lagged steel pipes. Terrendis also delivers innovation with its horizontal geothermal solutions, vertical probes and geothermal baskets designed to recover heat from the ground.
