AND IN PRACTICE... THE ADVANTAGES
Installation of a Hélicave Harnois cellar does not require a construction permit. It is guaranteed for ten years. It is also tax-exempt as it is not taken into consideration for property tax.
BETON CONCEPT, the licensee of the Hélicave patent, has over 80 years experience in the wine-making sector making concrete wine storage tanks for wine makers.
A world leader in the sector, the Nomblot brand is recognised for the quality of its products and its expertise.

Based on an original technique patented by Georges Harnois, Hélicave Harnois is a concept which is unique in the sector. SOCOTEC, the building control authority, has checked and approved the specifications for each model developed and installed by Hélicave Harnois. With SOCOTEL certification they are eligible for home improvement and construction loans.
