Are Precast Concrete Products Better Than Concrete Cast On-Site?

In construction, speed is essential. However, construction work is labour-intensive. Construction companies hire many workers to ensure the progress is not hampered. If there are distinctive features in the structure, it may lead to the hiring of skilled and specialized workers, which can add to the building cost. 

The availability of new construction products and new building techniques provides several advantages to companies and clients, from cost savings and faster construction process to additional aesthetic values, with the addition of more durable materials that are consistent, high quality, and low maintenance. 

Construction companies used to rely on concrete mixing and casting on-site. Now precast concrete products are available. What are the differences between the two, and which one is better? Let's find out. 

On-Site Cast Concrete 

With on-site casting, the concrete is mixed, poured, and moulded in fabricated removable moulds that are also prepared on-site. The concrete's curing time could be around seven days. Concrete is heavy, and when cast on-site it does not have to be transported too far. It is already there, so lifting it into place takes less time. On- site casting is preferable for structures that require large and custom concrete moulds. It can likewise be cheaper to use on-site casting for small projects. 

Since on-site cast concrete needs fewer joints, it's more suitable for areas that are prone to earthquakes. on-site cast concrete is stronger, which is why it is ideal for home foundations and basement walls. It can resist structural damage in the case of floods, earthquakes, strong winds, and rain. It can be reinforced with rebar or with steel rods and bars. 

Precast Concrete 

Several factories manufacture precast concrete. You can visit to learn more about precast construction materials. Factories produce concrete in a controlled environment. The product offers many advantages, but it also has its drawbacks. The finished products have to be moved, and due to the weight of concrete, it can limit the size of the product to be precast. It also requires the use of heavy and specialised equipment such as cranes to lift it into position. 

Construction work must include a detailed layout and plan to factor in building services like pipes and conduits, gas and water outlets, as well as power. Once in place, the precast concrete is difficult to alter, and the electrical and plumbing fixtures would not easy to add. 

According to previous studies, precast concrete products are cheaper than on-site cast concrete. Moreover, the controlled environment during the production of precast concrete ensures the consistent quality of the product no matter how many times a single design is produced. 

But precast concrete is flexible and durable and can be used for roofs, walls, and floors. The supply is reliable, and the precast concrete products come in various shapes, forms, and finishes. It can last for about 100 years and can be removed and relocated. Since it is pre-fabricated, it can be used immediately, which means that construction moves faster.
