Few construction materials are as durable or as versatile as concrete. With its century-long service life, concrete resists fire, erosion and weathering, is low-maintenance, and energy-efficient. It also comes in an extensive range of colors and finishes. This makes concrete the perfect material for retaining walls, pillars, and foundations. A concrete wall, in particular, is a popular choice for homeowners. Modern and industrial-style homes and buildings use raw, exposed concrete walls as a unique and eclectic focal element.
Concrete Wall ConstructionConcrete walls in houses and buildings often serve as the load-bearing structure. They also boost the safety and stability of the structure, especially during earthquakes. How concrete walls are built play a significant role in the life span and performance of the entire structure. Some of the common materials used in constructing concrete walls are the following: sand, cement, formwork materials such as wood or aluminum, steel reinforcement, and admixtures. Here’s a rough guide to our concrete wall construction process:
Designing the concrete wallIdentify the components to be used, how the space will function, and the size, shape, and placement of the wall.
Clearing andClearing and grubbing involves the removal of soil, plants, and other debris that may interfere with the construction process.
Building formworkConcrete wall forms are placed to keep concrete in place while it hardens. Some of the common formwork materials are wood, aluminum, and plastic.
Placement of reinforcement barsIf the concrete wall is less than 100 mm thick, one layer of steel bars should be installed. If it’s thicker than 200 mm, two layers of steel bars need to be installed. These bars are positioned vertically and horizontally, following a grid pattern.
Pouring and curing concreteMix concrete according to the manufacturer’s instructions, and pour it in layers, from one end to the other.
Placement of jointsConcrete walls may be built using any of the following joints: construction, contraction, and expansion. The first is placed between two consecutive pours of concrete, and the second allows the safe shrinkage of concrete. While the third helps with temperature-related expansion of the concrete.
Finishing stepsForms are removed. Once the concrete fully hardens, finish is applied on the surface.
