The Benefits of Tunnel Formwork

The Benefits of Tunnel Formwork

Tunnel formwork is a construction method that allows walls and slabs to be poured simultaneously, significantly speeding up the building process. It also helps to achieve high quality and durability, which is essential for buildings that need to withstand harsh environmental conditions.

Concrete tunnel formwork consists of a set of prefabricated modules that are easily assembled and dismantled. Each module consists of a metal frame with concrete shaping surfaces and a fastening system. Its telescopic nature makes it easy to adapt the size of each tunnel according to different project requirements and to specific building features. This allows multiple rooms to be concreted and provides flexibility in scheduling. The cycle time is 1 to 3 days, which is relatively short compared to other formwork systems.

The main advantage of tunnel formwork is its ability to increase daily casting areas from 350 m2 to 500 m2. This means that a lot more concrete can be cast in a shorter period of time, saving on labour and construction costs. Furthermore, the system has integrated working platforms and safety barriers to ensure that the workers can work in a safe environment. This also reduces the amount of rework that is required, further contributing to project cost savings.

Another benefit of tunnel formwork is its ability to deliver a near-perfect concrete surface, which significantly reduces the need for follow up plastering and painting. This in turn further cuts down on construction costs and enables quicker occupancy for the building owners.

Furthermore, concrete tunnel formwork offers great strength and durability. The monolithic structure created by this technique eliminates joints and weak points, making it better able to resist seismic forces and other environmental stresses. In addition, the tunnel formwork system is also highly energy-efficient and requires minimal maintenance over time.

The benefits of tunnel formwork make it a very appealing construction method for a wide range of projects. It is particularly suited for structures that need to be built quickly, such as schools and industrial plants. The construction process is streamlined and workflows are accelerated, helping to ensure that the building can be completed on schedule and within budget.

Using this construction method is not only more efficient but also cheaper than other methods, as the same formwork can be reused many times over without losing quality. In addition, the use of fewer materials means that there is less waste and the construction site is safer for workers.

Choosing the right formwork for your project is a key factor in the success of your build. For example, it will determine how long the concrete takes to reach its strike strength and how much time is available for rebar installation. To get the most out of your formwork, contact a specialist to learn more about the options available for your building.
