Shuttering means installing formwork. Formwork is needed when liquid materials, such as concrete, are used for construction. It should be installed and secured before concrete is poured, and if needed, reinforcement is installed, too. Formwork is usually made of timber, but it can also be plastic or metal. There’s also special formwork intended for more complex shapes. Installation of formwork is done with more care when the formed concrete, its texture and colour, will remain visible once installed. Formwork dismantling also requires extra care. This can happen on the day after the concrete is poured, but pay attention if the concrete is pre-stressed and if there’s a risk of cracking. As a rule, it takes 28 days for concrete to reach its full effective strength, which is why the formwork should stay put for at least 3 weeks.
