Concrete is one of the most durable materials out there. However, it can be extremely delicate. This is particularly true during installation and pouring. Concrete is also prone to sun damage and other types of decline even after it has set. Unluckily, these damages can happen more often if the installation was shoddy from the beginning.

Today, we’re going to share with you a couple of indications of shoddy concrete pouring. If you want to avoid these issues, make sure you hire a reliable concrete contractor.

Cracking

This is probably the most obvious indication of shoddy concrete workmanship. The main cause of cracking in dried concrete is the structure’s tensile stress. This typically occurs if there’s excessive weight settling on one end of the surface, violent movements, and miscalculations of the material’s strength. Cracks can stay on the surface. However, they can also extend all the way through the membrane.

To prevent cracks, the contractor needs to use proper materials and correct calculations. A couple of forms of concrete have various resistance to tensile stress. Another crucial thing to consider is the inner support structure.

Honeycombing

This indication of shoddy concrete pouring appears like several voids and air pockets in the concrete. This might appear like rough surfaces on the exterior. However, it can show as risky empty spaces deep inside the concrete. This usually occurs due to the inability of the contractor to properly fill-up the areas with correct materials.

This type of issue is extremely hard to notice since you can only see it once the concrete has set. The severity of concrete honeycombing is characterized by how deep the voids and air pockets are in the building.

Delamination

This issue refers to the pieces of concrete that separate from other layers to a huge degree. However, these pieces still stay in the bigger part of the building. While the piece might appear stable and solid, it is not. You can recognize delaminated areas by gently tapping the surface. An echoey and hollow thump will show that there’s a space behind the concrete. This means it has separated already.

This problem happens if the interior of the concrete is damaged. For instance, there’s a buckling of supports embedded inside or deep cracks inside the building. Aside from that, it also occurs if the contractor overlays a new concrete layer on top of old, dilapidated concrete.

Bleeding

This type of issue refers to excessive water and moisture seeping into the poured concrete’s surface. During this process, the heavier deposits will settle to the bottom. Because of this, water is forced upwards. This will appear like puddles or thin slicks of water.

While a couple of amounts of bleeding is unavoidable during settling, too much water affects the concrete’s durability. This is particularly true if the concrete is used for the support or foundation columns. Excessive bleeding is an indication that too much water has seeped into the cement. Aside from that, excessive bleeding can lead to a lot of various issues after the concrete has been set.
