What is Predalle in Construction?
Predalle is a pre‑stressed, pre‑cast roofing panel system that combines speed of installation with excellent structural performance. It arrives on site as a high‑quality pre‑cast element and is then completed with a second‑phase concrete pour — producing a robust slab with a clean soffit finish.
If you’re planning a build that demands structural integrity, predictable programme, and professional finishes, explore how pre‑stressed Predalle manufacturing can elevate your next project.
Why Predalle is taking off in Malta
Malta’s projects demand consistent quality, predictable schedules, and reliable performance. Predalle delivers all three. Because panels are produced off‑site under controlled conditions, you get repeatable accuracy — and a build programme that keeps moving.
Less site congestion
Reduced shuttering and on‑site labour, plus cleaner sequencing around lifts and pours.
Design flexibility
Integrate openings and service routes early for smooth MEP coordination.
Higher confidence
Factory consistency plus strong composite slab behaviour once poured.

Predalle, explained in two ways
Choose the view you need: a marketing‑led overview for decision makers, or a technical breakdown for consultants and site teams.
Marketing: Build faster. Finish cleaner. Perform stronger.
Predalle is ideal when you want the strength of a solid slab — but with a smarter workflow. You get rapid installation, fewer wet trades on site, and an underside finish that looks sharp even before final decoration.

Technical: Specifications, interfaces & performance
Predalle panels are produced as pre‑cast elements with a smooth fair‑face underside and a roughened upper surface to form a strong bond with the second‑phase concrete pour. Panels are typically supplied with reinforcement, transversal steel, and lifting provisions to support safe handling and placement.
Typical thickness
Standard panel thickness is commonly between 6–10 cm (project dependent).
Interface finish
Roughened top surface for improved adhesion to in‑situ concrete.
Edge detailing
Chamfered edges can support a neat, consistent finish.

Predalle FAQs
Clear answers that help clients, consultants, and site teams make faster decisions.
Is Predalle only for roofs?
It’s widely used for roofing and intermediate floors. Your engineer will confirm suitability based on span, loads, bearings, and detailing.
How does Predalle improve structural integrity?
Pre‑stressing supports efficient load behaviour, and the composite action with the second‑phase pour helps create a robust slab system.
Can services be coordinated within the slab zone?
Yes — Predalle supports clean service coordination when openings and routes are planned early with your MEP team and structural engineer.
Do you supply other pre‑cast elements?
Yes. Alongside Predalle, B&B manufactures a range of pre‑cast and concrete products to support complete build packages.
