Crezza manufactures precast retaining walls made of reinforced concrete panels, equipped on the earth-facing side with a stiffening rib (buttress) from the base to the top, installed on a foundation curb and then integrated through slab casting.

Custom-made prefabrication to meet a wide range of needs, each containment wall features an exposed face designed to minimize environmental impact: with a formwork finish, patterned, or clad with stone to ensure perfect anchoring: depending on the type of stone used, the exposed face of the wall may have regular or irregular courses in “Opus Incertum” style.

The reinforced concrete walls are manufactured in modules with variable heights and constant widths, allowing for quick installation and the high-quality materials used in prefabrication ensure long-lasting durability. The flat or tapered capping, when staggered relative to the wall, allows for interruption and provides an aesthetically pleasing appearance.

Suspended or lateral escape routes are among the precast structures for tunnels, made of vibrated reinforced concrete, ensuring easy evacuation from tunnels in the event of an emergency. These precast escape routes come in various shapes, rectangular or trapezoidal, depending on the requirements, and are connected to the tunnel structure through tie rods or bolted plates.

In compliance with passive fire protection regulations, an area where Crezza offers consulting and supply services, the escape route structures can be further coated and protected with materials designed to reduce temperatures in case of a tunnel fire.

Crezza extends its range of precast products for tunnels and galleries with sound-absorbing barriers made of precast reinforced concrete acoustic panels: these panels consist of a high acoustic absorption concrete layer and a load bearing reinforced concrete layer.

Available in various coatings and colors to reduce landscape impact, these concrete insulating panels are applied inside underground crossings and tunnels to reduce noise pollution, they can be integrated with metal profiles or installed on support elements like concrete walls.

In addition to production, Crezza offers a turnkey service, including the supply and installation of sound-absorbing acoustic panels, insulating systems designed to fit any project, with minimal footprint and very low maintenance requirements.

Crezza’s concrete prefabrication range includes reinforced concrete cladding elements designed for covering walls in civil and industrial buildings, floors, piles and soldier pile walls, artificial canals. In addition to precast panels, the company supplies Predalles slabs, consisting of a reinforced concrete slab strengthened with lattice girders, custom-designed with variable thickness and dimensions according to the intended use.

Advantages of precast cladding panels and slabs:

• Fast, easy, and cost-effective installation, achievable with standard lifting equipment;
• Reduced installation time and significant savings in formwork materials;
• High safety during installation;
• The ability to use the slabs as lost formwork, even self-supporting for high-load floors.
