Unbrako Prestressed Concrete Walling

Detailed Information

Our prestressed concrete walling will work for both the agricultural and industrial sector, from bulk & grain storage to livestock buildings & silage pits, these walls are designed to provide sturdy storage.

The Use of Prestressed Concrete for Concrete Walling

Prestressed concrete is a construction technique that involves introducing internal forces into the concrete before it is subjected to external loads. These internal forces are typically in the form of pre-compression, which counteracts the tensile forces that the concrete would normally experience when subjected to loads.
The process of prestressing involves placing high-strength steel tendons or cables, called prestressing tendons, into the concrete element before it hardens. These tendons are tensioned using hydraulic jacks, applying a significant amount of force to the concrete. Once the tendons are tensioned, they are anchored at the ends of the concrete element to maintain the pre-compression.

There are two main types of prestressing methods:
In pre-tensioning, the steel tendons or cables are tensioned before the concrete is poured. The tendons are temporarily anchored at one end of the formwork, and once the concrete has gained sufficient strength, they are released from the anchorage. The pre-stressing force in the tendons transfers to the concrete, creating compression.
In post-tensioning, the steel tendons or cables are placed in the formwork, and once the concrete has hardened, they are tensioned using hydraulic jacks. The tendons are then anchored to the ends of the concrete element, and the jacks are released. The pre-stressing force in the tendons is transferred to the concrete, inducing compression.

Prestressed Concrete Walling Panels:
Description: Prestressed concrete walling panels are large precast concrete panels that are usually used as external walls in buildings or as retaining walls in infrastructure projects.
Installation: They are manufactured off-site and then transported to the construction site for installation.
Design: Walling panels can have various finishes, patterns, and textures to meet specific architectural requirements.
Strength and Durability: Prestressed concrete walling panels have high structural strength and can resist significant loads and forces. They offer excellent durability and long-term performance.
Applications: They are commonly used in commercial and industrial buildings, agricultural structures, and infrastructure projects like sound barriers and retaining walls.

Freestanding Retaining Concrete Walls
Description: Freestanding retaining concrete walls are designed to retain soil or provide separation between different areas of land. They can be used in landscaping or civil engineering projects.
Installation: These walls are typically constructed on-site using precast concrete blocks or poured-in-place concrete.
Design: They can be designed with a variety of finishes, such as smooth, textured, or patterned surfaces.
Strength and Durability: Freestanding retaining concrete walls are engineered to withstand lateral soil pressure and retain the soil behind them. The prestressed concrete ensures high strength and durability.
Applications: They are commonly used in residential, commercial, and infrastructure projects, such as gardens, parks, and road embankments.
