The system includes a polymer based waterproof barrier that enhances adhesion by heat transfer.
The surface reinforcement made of a synthetic mineral fabric has excellent dimensional stability and outstanding mechanical properties.
The upper part of the diaphragm is protected by a special nonwoven polymer fiber fabric, allowing application without compromising the bitumen spreading and truly accentuating its perfect penetration. The underside is covered with a molten thermoplastic film.
The layers connected to the roadbed are stressed due to the influence of the road surface flexion when motorized vehicles travel or heavy loads.
These tensile forces are lower than the tensile strength of the material, but the cyclical nature of the stress causes the tensile strength to decrease and causes very small and increasingly large cracks. GRID BIT DS, to be applied depending on the degree of upper or lower failure of the binder, acts as a barrier to prevent cracking from spreading to other layers.
