Precast Concrete Walls Pros and Cons

You may have heard of architectural projects built in recorded time. Raising houses in 03 days and working a week are frequent news in architecture and construction sites.

What you probably still do not know is that most of these projects use multi-laminar and precast concrete walls, novelty kinds of building materials in Brazil.

To answer your questions, the webpage made a dossier with all you need to know about precast concrete and multi-laminar walls, which already are available in the work, starting with the production of the material:

Making off

It all starts with the cutting and welding of metal structures made according to the paper of architectural design. They are the molds of concrete structures poured in module tables in a factory. Later, these molds can be reused, following the construction of industrialization trend.

In this process, all hydraulic lines, electrical, doors, windows and frames are considered and built into the structure. View wallstickercollection for textured feature walls.

The surface passes through a concrete vibration process for 24 hours. After drying, it can be taken immediately to work to be “mounted” to winches with panels connected by welding.

After welding, the property can be used immediately.

To understand the speed of the system better, it is estimated that a multi-laminar concrete wall to be built in 2 hours while there are 36 hours of the regular building or spent in conventional masonry. Understand the difference.

This is because the precast panels function structurally and hermetically, and panels do not require foundations, strapping, spars, slurry mortars, plaster, plasters etc.

The production and assembly are mechanized and cost little labor.

It is also very common for the precast concrete compared to the steel frame, dry-wall and other dry construction systems.

But this union structure and coverage make people put forward other methods, with the advantage that in its composition, the concrete can be diversified and added carbon fibers, ceramics and even debris. To recycle materials, increase insulation thermal and acoustic etc.


The applications are innumerable. Although they are modular structures, precast concrete preserves its architectural freedom and can be molded into various shapes.

More used in residential projects and public housing (the latter mainly by the potential serialization construction) nothing prevents the precast concrete to structure residential and industrial buildings of all proportion.

Just a few structural calculations and the combination of concrete and metal structures are needed. Nevertheless, the natural resistance of multi-laminar walls can withstand natural disasters such as hurricanes and earthquakes.

And for people who care about finishing, precast concrete does not offer any kind of restriction. The painting can be made by dipping the plants in the wall, plaster, and spackling.

Coatings, flooring, wallpapers and so on, they can be applied without any problems.


Fast, cost-effective, low-loss materials, individuation, strength and durability, everything seems to count in favor of precast concrete and multi-laminar panels.

Perhaps the only drawback of this construction method is the difficulty of reform.

Any change should also be planned in the design phase, since it is relatively difficult to operate any change that impacts the property structure.
