Frequently asked questions
Everything you need to know
Is MODU BLOCK compatible with all surfaces?
Yes, the anchoring system works on asphalt, concrete, paving stones or compacted earth. An optional base plate ensures watertightness on uneven ground.
How long does it take to install 30 linear metres?
Two operators can deploy 30 m (10 modules) in under 2 hours. Removal is equally quick, enabling a rapid emergency response.
What is the lifespan of the modules?
The steel benefits from anti-corrosion treatment guaranteed for 25 years. The recycled plastic resists UV and freeze-thaw cycles. Estimated lifespan: 30 years+.
Is the system certified?
Yes, the 60 kN/m² resistance is validated by tests in an accredited laboratory. The complete technical file is available on request.
Do you offer rental or only purchase?
Jean Four sells MODU BLOCK to guarantee ownership and reuse. Financing solutions on quote are available for local authorities.
Can sections be linked for long perimeters?
Yes. Modules connect end-to-end with watertight connectors. Angled or T-shaped configurations are possible to protect geographically complex zones.
