The construction of a concrete structure requires formwork to support the concrete loads after the pouring process. From here, the formwork stays in place, becomes hard, and gains some strength. Depending on the concrete, the formworks remain for 7 to 15 days.

Most Common Causes of Concrete Formwork Failure

Let us now take a look at some of the top causes of formwork failure here.

Inadequate Bracing

Improper bracing during construction can fail formwork. Having improper horizontal and cross bracing of shores can lead to this primarily. Lateral force generates from poor bracing and creates lateral deformation. Due to failure at one point, the bracing allows the collapse over a large portion, creating multiple damages. However, this isn’t the case with plastic shuttering.

Short Of Concrete Placement Control

It is essential to regulate the rate of concrete placement on a horizontal framework. It creates improper loading balance, resulting in formwork failure. The temperature, chemistry, vertical placement, and concrete vibration impact the lateral pressure to act on the formwork.

Strength, stability, and mechanical properties make plastic formwork preferable over conventional shuttering.

Inadequate Strength Development

It is another factor that contributes to formwork failure. The elements of the formwork should have adequate cross-sections to give strength to the loads imposed on the formwork. This is of great importance to check the strength when casting a rising level of building construction. The concrete may fail at the anchors resulting in scaffolding and collapse.

Lack or Improper Formwork Design

Improper design of the formwork by engineers makes the formwork fragile to carry a suitable load. This problem arises during construction and requires the designers to anticipate the actual design to support the formwork. It requires checking the safety factors of the design by a suitable engineer. Plastic formwork is a cost-effective and flexible option that makes it more convincing than concrete formwork.

Premature Formwork Stripping

Premature stripping of any form or removal of the shores requires attention, otherwise can lead to disastrous problems. This can lead to severe problems in multistorey buildings. Here, one floor’s collapse leads to the other’s collapse. It can happen due to early stripping of formwork which is not desirable. It may ask for reconstruction due to the demolition of the building.

Inadequate Soils Below Mudsills

The formworks collapse due to soils under the mudsills. These are the base of a shore. The mudsill can be like a frame, timber plank, small footing or any pedestal. It is important to choose the right shuttering for concrete construction. It can prevent the chance of sudden failure of the construction.

So, it is preferable to choose plastic formwork over conventional concrete ones. It can reduce the chance of damage, the plastic form is easy to fix and clean, and it requires less shuttering oil.
