Alongside SUBTERRA this month for the successful HDD installation of a 206-metre-long DN355 water pipe in Preignan, near Toulouse, in southern France, as part of the pipeline renovation programme being carried out to secure the Gers region’s water installation and distribution network.
The new HDPE pipes cross under SNCF railway tracks, an A road as well as housing, and are better suited to the risk of shrinkage and swelling inherent to the site’s clayey marl soils than the previous steel ones.
OPTIMUM trenchless specialists worked with SUBTERRA prior to the drilling works to validate the project engineering, design the crossing plans and carry out ground settlement analysis. They then accompanied SUBTERRA throughout the construction phase to advise on necessary adaptations as drilling progressed: profile adjustment, tool modification, etc.).
Great teamwork throughout, sticking to both the timeframe and the budget.
