Dry construction: Types, characteristics and advantages. Understand it all now!

Building requires time, work and commitment, but have you ever thought if there was a solution that would make the whole process easier? Engineers, architects and master builders are always looking for methods that can optimise the entire construction process.

Dry construction is a method that simplifies the stages, but still ensures safety, quality and durability for any construction work. It is about it that we are going to talk in this article. Widely used in North America, Asia and Europe, this alternative construction method is also gaining strength in Brazil because of its characteristics and numerous advantages that it offers throughout the construction process.

As it is a method that differs from traditional construction because of its agility, cost, economy and cleanliness, you need to know more about this subject to keep up to date with what is happening in the Brazilian civil construction market, which tends to increasingly adopt this innovative construction method.

Thinking about the growth in the use of this construction method, we thought of doing this article to bring important information about this subject. Here, you will understand what dry construction consists of, what are its main types, differences with conventional construction and, finally, what are the advantages and disadvantages that this method provides. If you want to know all this, it is simple: just read this article until the end. Let's go?

What is dry construction?

Before anything else, let's start with the basic question on the subject that you need to know the answer to in order to continue delving into the topic: what is dry construction?

Dry construction is nothing more than a construction process that dispenses the use of water in all stages, avoiding mixtures and the use of mortar. But how is the process carried out, then? Basically, the structures are manufactured in industries and are only assembled and installed at the construction sites.

Despite so many benefits and being an innovative method, dry construction has not yet arrived for good in Brazil. Here, the most used method is still, without a doubt, the conventional masonry construction. This is due to some factors, such as resistance in using something new, little diversity of suppliers and less availability in the market. But, it is good that you are already familiarizing yourself with this method, because sooner or later, it will come to stay in the Brazilian market. Its benefits are many and this must be the reason why it is already widely used in other regions.

What are the main types of dry construction?

There are some types of dry construction, which vary according to the type of material and technique that will be employed in the process.

First, we must clarify that there are two basic types of structure: Wood Frame and Steel Frame. Wood Frame is when the structure of the whole construction is made of wood while Steel Frame is composed of metal profiles. There are some types that the coating itself is also the structure, in the case of EPS Panels, Concrete Double Wall and Plaster Blocks. When we talk about drywall or cementitious plates, the structure can be Wood or Steel Frame.

Let's understand a little better about these types:

  • Plaster Boards: with plaster boards(drywall), it is possible to fit them both into a steel structure (Steel Frame) as wood (Wood Frame), gaining agility and economy throughout the process. It guarantees good thermal and acoustic insulation.
  • Cementitious slabs: this is the same situation as plasterboards, but they are slabs made of cement, which can be installed on a steel or wooden structure. They do not provide good thermal and acoustic insulation.
  • Plaster block: plaster blocks are part of both the structure and the finish (coating) of the construction. They speed up the construction work.
  • EPS panels: it is the most consolidated in the Brazilian market. It consists of expanded polystyrene sheets on steel mesh that are concreted or screwed. It ensures a resistant, lightweight structure that acts as thermal insulation.
  • Double Concrete Wall: this system consists in the use of precast concrete slabs ready to be applied at the construction site. The slabs are connected to a lattice reinforcement with a structural function. The gap between the plates that will make up the walls must be filled with Styrofoam, concrete or expanded polyurethane. Execution is very quick.

These are the main types of dry construction that exist. Each of them has its own characteristics and advantages and disadvantages. That is why it is important to study each type well to find out which one best suits your needs. Always count on professional help to reach a conclusion that is favourable to you.

What is the difference with conventional construction?

What differs conventional masonry construction from dry construction is basically the use of water in all stages. Therefore, the dry construction method dispenses with the use of mixtures and mortars.

Among the main differences between conventional and dry construction, we can mention: dry construction is much faster, wastes much less material, time and labor. Also, the costs in a dry construction are more predictable, giving you an idea of how much you will spend in the total work. Masonry can suffer with unexpected changes in the budget.

Despite being a very innovative option, the conventional method is still the most used in Brazil. However, in other countries, this construction model is very common and tends to enter the Brazilian market with strength as well.

What are the advantages of dry construction?

Now, I will introduce you to the advantages of dry construction, which are several. We can mention them:

  • Much faster execution: the time to complete the work is much shorter, but the cost is higher. You can speed up the processes without losing quality.
  • Reduction of material waste: the construction model optimises the use of inputs, reducing waste. It can be said that it is a more sustainable construction.
  • Budget true to plan: the system allows the final budget to be very close to the planned one, avoiding unplanned expenses.
  • Economy: although today dry construction is a little more expensive, there is a significant reduction in the final value of the work due to less time, labour and equipment required.
  • Durability: a work made by dry construction lasts for many years, just as if it were made of traditional masonry.
  • Simple maintenance: if you need to make any changes in the construction, it is very fast, practical and much cheaper. The maintenance costs are ⅓ less when compared to the conventional system.

What about disadvantages?

Now that you know the advantages that dry construction can provide, it's time to learn about its disadvantages.

As it is a model of construction that is still little used in Brazil, it can be a little more expensive due to the small amount of suppliers and labour, which can increase the total budget of the work. However, you need to consider that it is a construction that is raised in a short time. Thus, it is important to weigh its pros and cons to evaluate if it is an advantageous model for you.

There is also a cultural issue and resistance regarding adherence to the dry construction model because it is little used in Brazil. However, this is a question of time. It won't take long for this model to enter the domestic market.

Conclusion

Did you like to know more about dry construction? It is a very interesting and different way of building, but one that is going to stay in the Brazilian market.
