Project, solution, service and innovation for Sibca

WALL'UP PREFA was born out of the synergies of the wood/hemp industry groups in the Ile-de-France region, aware that a joint response to the challenges of biosourced prefabrication would not only meet the needs of the current and future construction market, but also consolidate outlets for the resources extracted in the region.

To emerge, the company drew on the knowledge of its founders, combining expertise in wood construction with experience in hemp cultivation and processing.

Hemp, CSR by nature
Wall'up Préfa prefabrication is also a response to environmental and social issues:

- cultivation without inputs or pesticides, no irrigation required
- Chemical-free defibration
- Planted/harvested an average of 30kms from the hemp mill
- C0² storage (1ha of hemp stores 15T of C0²)
- No production waste
- Re-industrialization of the region
- Establishment of excellent know-how
- Comfort and safety for employees and subcontractors

Industrialized construction
Wall'up's vision is to support off-site industrialized construction, by producing mantle walls with a positive impact on the environment (0 VOCs, carbon sinks, etc. Wood and hemp are CO2 sinks).

A short supply chain: to control the traceability of materials from A to Z, and limit carbon impact. A responsible production method (no inputs used for hemp production, and mechanical defibration using no chemicals), reducing all production waste to zero.

A building system adapted to today's production methods: the building system is suitable for all types of conventional load-bearing structures (concrete, wood, metal).

Use of materials adapted to their function: hemp concrete has exceptional thermal comfort qualities, limiting the need for complex ventilation engineering and eliminating the need for air conditioning.

Prefabrication down to the last detail: the aim is to push off-site construction to the limit, offering the possibility of planning for the passage of fluids or future installations that will pass through the walls, as well as a wide range of finishes (interior/exterior). This reduces site constraints and waste.
Together, these assets contribute to the "revolution" expected by the Elan law on construction methods (build more, faster, cheaper).
