Common Defects in Concrete Formworks

Common Defects in Concrete Formworks Concrete is a common construction material due to its versatility and stability. In most cases, concrete structures can last for more than 20-30 years. The durability of a structure depends on two factors: material and formwork. Errors and poor construction practices in formwork development make a concrete foundation weak.

Due to the formwork errors, you may experience a few common defects in the concrete formwork.

Finding professional concrete formwork companies is essential for this reason. In the following section, you can find a detailed discussion on common concrete defects.

1. Fine Cracks on the Concrete Surface You may have seen fine cracks on the concrete structures often. In most cases, cracks appear on the upper surface of the concrete structure. You do not have a big concern if the cracks are present only on the top surfaces. The concern begins when you see the deep cracks in the concrete structure.

Cracks appearing due to poor formwork are progressive. In other words, you will find such cracks spreading quickly on the concrete surface. Moreover, they will widen with the advent of time.

Therefore, the overall concrete structure will become weak.

2. Blistering Signs on the Surface Many people think that heat may cause blistering signs on concrete surfaces. However, it actually happens due to two significant reasons. Firstly, water damage to the concrete structure causes those blistering signs. Secondly, blistering signs can appear due to formwork problems.

Poor construction practices in concrete formwork development cause the appearance of blistering marks on the concrete surface. Typically, the blistering signs become larger with the advent of time. The overall concrete surface can damage to a significant extent if you do not take quick measures to repair the blistering marks.

3. Dusting Concrete surface dusting is another prominent sign of concrete formwork defects. Dusting can happen due to many reasons, though poor-quality concrete formwork is the most prominent reason in such cases. Dusting causes gradual decay to the concrete surface, and you will find the surface has become uneven soon.

A common way of checking to dust is using an iron wire comb to scratch the concrete surface. However, a structure with poor formwork will quickly lose a good amount of dust. Therefore, you need to take quick measures to resolve this problem with concrete formwork.

4. Concrete Surface Curling

You can also notice concrete surface curling at times. Curling creates an uneven surface, though you will not see other damage signs. The concrete surface curling is concerning, as it makes the structure weaker inside. As a result, there is a high risk that the structure may fall down after a certain time if negligence in maintenance happens.

So, these are some common signs of concrete formwork defects. You can find many other signs of a poorly followed formwork method. You need to repair such concrete structures frequently to maintain an effortless strength. For concrete formwork development, concrete shuttering has a crucial role to play.
