WorkInstallation of the underground cellar
Hélicave Harnois has overcome the difficult problem of underground water-proofing. Before the racks are fitted, the entire excavation is lined with e Butyl liner which is pre-fabricated at the factory. Our cellars are therefore comparable to traditional ones in terms of their robustness, their conservation properties and storage capacities while incorporating an effective and original water-proofing system.
A “siteless” building site.
Our installation staff are well-trained and experienced and you will hardly notice they are there :
- We can install cellars throughout the year and when it best suits you,
- Excavation performed as required for installation,
- All supply, assembly and commissioning is completed within 8 days,
- The site is made good at the end of the works.
About the Butyl water-proofing liner
The liner used to waterproof our cellars is made from UNIVEX Butyl synthetic rubber.
Butyl is elastic, durable and rot-proof. It is supplied in rolls, pieces are cut and then heat-sealed together to form the walls and floor of the liner. To test the seal, the liners are closed using vulcanised joints and then inflated to 12 mb for 15 hours in order to detect any leaks which may be present.
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.
An excellent investment
With turnkey delivery after approval of the estimate, Hélicave Harnois is a great investment. As well as adding value to your property, the investment is justified by the value added to the vintage wines you will store in them.
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.
