(1) mBio7 can also be used for partition walls, floors and roofs — comparison limited to exterior structure only.
(2) To reach R ≥ 5 m².K/W (building regs), an interior EPS + plasterboard lining suffices in both cases.
(3) mBio7 greatly reduces physical labour and requires no water on site.

Key Advantages — Page 5 / 6
Key strengths
The Decisive Advantages of mBio7
🚫No foundation required
The system’s light weight (1,950 kg vs 19,000 kg) eliminates the need for reinforced foundations, drastically reducing both cost and construction time. Can be placed directly on a slab or even without one.
⚡Ready to use immediately
No drying time, no cement curing. The structure is operational as soon as assembly is complete, regardless of weather conditions. No frost or rain constraints during or after assembly.
✂Hollow, adaptable structure
Electrical conduits, plumbing, windows and extensions are all facilitated by the hollow wall structure. Easy to cut with a saw. Off-cuts are reusable. Modifications or extensions possible at any time.
♻90% recycled materials
Optimal carbon footprint thanks to 100% recycled materials and greatly reduced transport: only 4 pallets vs 15 for traditional masonry. A genuinely eco-responsible construction approach.
🛡Earthquake-proof · Crack-proof
mBio7 panels cannot crack. A key argument for seismic zones, unstable ground or high-risk areas. Superior mechanical resistance compared to traditional concrete blocks.
💧Zero water on site
No water required to build with mBio7. Considerably reduces physical strain. Ideal for remote, hard-to-access or constrained construction sites.
📐+4.5% more living space
The reduced wall thickness generates 2.32 m² of extra habitable area on a 56 m² building — 53.62 m² vs 51.30 m² with traditional masonry.
🔄Dismantlable & reusable
Clean dismantling with no bulky rubble. Panels can be reused in another construction. Near-zero deconstruction cost — versus expensive demolition with traditional masonry.
mBio7 also dramatically reduces physical labour
No water needed · Very limited equipment · No heavy machinery · Wall straightness guaranteed by panel interlocking — no specialist skills required
