Traditional pocket solutions create technical and re-use problems :
• Polystyrene solutions pollute and are now obsolete.
• Cardboard is not appropriate for concrete: its lack of resistance to wet weather makes it a solution to avoid.
• Plastic sheets bent into shape generate increased labour costs and do not provide guaranteed reliability.
Révolubat pockets made of injected polypropylene meet these technical constraints and the economic challenges of the construction sites of modern buildings.
