Rental · Bio-based concrete projection unit
Mobile solution for the mechanised application of bio-based materials (hemp-lime, earth-hemp, etc.) via dry process with nozzle mixing. Up to 10 m³/day.
Unit developed from years of on-site experimentation. The fibre is carded and blown separately, the binder is prepared in a dedicated mixer and then pumped independently; the materials are assembled directly in the nozzle before projection. Rental systematically includes 1 or 2 Argibat / Cartdesign operators.
Technical specifications
- Dry process projection, nozzle mixing
- Capacity up to 10 m³/day
- 25 m hoses (extension +5 m possible)
- Single-phase possible depending on config.
- Minimum 2 × 16 A independent recommended
- Transport by truck + flat-bed trailer BE
Compatible materials
- Earth · Hemp-lime · Earth-hemp · Earth-straw
- Blends based on plant fibres
Included operators
- Equipment installation and calibration
- Project organisation
- Supervision of mix preparation
- Management of projection settings
- Team training and support
- Yield and quality optimisation
Operators provide technical assistance: they do not carry out the works in place of the site teams.
Usage tips
- Stable and accessible area for supply
- Material moisture content to be checked
- Regular supply of fibres/earth/lime
Recommended PPE
- Dust mask
- Safety goggles
- Hearing protection
- Suitable gloves

- Machine weight: ±80 kg
- Production: 60 to 120 bricks/hour (2 people)
- Operation: manual lever
- Steel construction, no power required
- Dismountable and transportable
Production & benefits
- No firing required, low carbon footprint
- Use of local raw materials
- Suitable for earth, stabilised earth, lime-earth
- Load-bearing capacity comparable to brick
- Reproducible on-site result
- Easy-to-learn technique
Applications
- Load-bearing walls and partitions
- Fences and boundary walls
- Floor surfaces and paths
- Decorative elements
- Humanitarian and community projects
Rustic stool

Introduction to bio-based materials
Practical one-day introduction: presentation of materials (lime, hemp, straw, earth), handling, application on test wall. Individual or group.
Practical introduction to bio-based and geo-sourced materials. Suitable for individuals who want to understand before renovating, as well as professionals looking to expand their range. The day alternates short theory with hands-on practice on a test wall.
Day programme
- Presentation of materials: lime, hemp, straw, raw clay
- Logic of dry and wet application
- Demonstration of mechanised projection
- Hands-on practice on test wall (render, projection, laying)
- Dosage selection based on substrate and use
Who it's for
- Individuals with renovation projects
- Self-builders
- Craftsmen looking to train in bio-based
- Architects and project managers
- Collectives and participatory projects
Details
- Individual or group (max 6 people)
- Location: Waleffes or on your site
- Duration: 1 day (9am–5pm)
- Materials provided
- Fee on request depending on group and location
