What Happens During Concrete Installation?

Concrete is one of the strongest and most durable building materials available. Yet, like any other material it requires a high level of skill to properly install and use. Sloppy work can lead to structural problems and endanger the safety of occupants. This article describes the steps that take place during Concrete installation and identifies common signs of poor workmanship.

What is the first step in pouring concrete?

1. The job site must be prepared. This involves contacting the local building department to learn about setback requirements and securing the necessary permits. The area should also be cleaned and cleared of grass, rocks, wood, debris and other waste. The ground must then be compacted and graded. If a slab is to be placed on a slope, the concrete contractors must ensure that the top of the slope is watertight and that it will drain well.

2. Wood forms are constructed and used to mold the concrete. This is a critical stage in concrete construction. Wooden forms are often made from softwoods such as spruce, pine or fir. They are fitted over the soil and secured by braces, stakes or tie wires. These forms need to be reinforced with rebar or wire mesh before the concrete can be poured inside.

3. Once the concrete has been poured, a process called “bleeding” occurs. This is where water comes to the surface of the concrete as it sets, forming thin slicks or puddles on the surface. This is usually the first sign of a poor concrete pour.
