5 Main Problems that Concrete Contractors Should Address

Every concrete contractor Los Angeles company go through various challenges when installing or repairing concrete surfaces. Although concrete is a very manageable material, it requires certain settings and considerations for it to dry and set effectively. Here are some of the main issues that most concrete contractors encounter and why it should be addressed immediately:

1. Discoloration

Inconsistencies in color could appear on both new and old concrete slabs. On newly installed concrete, discoloration could result from various causes. One is the amount of water used upon mixing cement. Another reason could be poor workmanship and other types of materials mixed with cement, such as calcium chloride. Although this is just a surface flaw, it can lower the aesthetic appeal of the concrete surface. This can easily be remedied with concrete stains or an extensive polishing process.

2. Cracking

There are two types of cracks: working and non-working. Working cracks are caused by recurring movement under the slab. Adding custom scorelines or expansion joints can help mask cracks while also giving the slab enough room to move without creating more cracks. Non-working cracks are often caused by long-time use, age, outdoor weather changes, or subgrade compaction issues.

3. Uneven Slabs

Often caused by improper subgrade preparation, uneven slabs are both ugly and dangerous. Instead of a complete flooring overhaul, the best way to fix this is through slab jacking or mud jacking. This is the process of injecting a certain type of grout under the slab through a hole. The grout fills in the empty spaces underneath the concrete floor while slowly pushing the slab upwards until it becomes even.

4. Scaling

This is often characterized by flaking and peeling concrete surfaces. This is often caused by water seeping into the porous concrete surface, especially on pool decks where splashes of water are frequent. Other causes include improper curing and low concrete strength. Concrete overlays, such as pool deck resurfacing Los Angeles products, are ideal solutions to this type of problem. A stamped concrete overlay, epoxy flooring, polyurea polyaspartic, or an acrylic concrete coating are all efficient in preventing concrete scaling.

5. Curling

Curling is when concrete slabs shrink in certain areas, causing a wavy concrete surface. This is often caused by inconsistent amounts of moisture and temperature in the top and bottom of the slab. While this can be repaired, the process can be long and difficult. It is important for concrete contractors to be careful in installing new concrete and observing proper curing techniques to avoid this type of problem.
