The Building Construction Process Explained

If you want to learn about the construction process and the steps that are taken to complete a project, you should read my blog. My name is Darren White and I've always been fascinated by the way that a construction crew can erect a building so fast. I work in an industrial park and there's always new buildings being built and I see the progress every day. A few months ago, I was at a neighborhood picnic and I started talking to a neighbor that lived down the street. It just so happened that he was a contractor that worked on the buildings in the industrial park. I asked him how the construction crew could build a huge building so quickly and he explained the whole process to me. That's when I had the idea to write a blog to explain the building process to others who are also interested.

Concrete Fall Hazards And Concrete Grinding

by Edwin Johnston

Concrete is not an indestructible material. It can crack, chip, and break. If the concrete is in a walking area, like sidewalks or driveways, a small problem can quickly become a fall hazard. Continue reading to learn about the causes of fall hazards with concrete and when concrete grinding can correct the problem.

Soil Settlement

Soil settlement is the most common cause of damaged concrete that leads to fall hazards. When the ground is being prepared for concrete installation, the soil has to be well compacted. If the soil is not compacted as it should be, it will move over time and stop supporting the concrete.

When the soil has moved below the concrete, the concrete itself moves and settles. This causes the concrete to be lower than its surroundings such as curbs and other parts of the sidewalk.

Some people try to correct this problem by concrete grinding to level the sidewalk again. This can be a good solution if the settlement is not large, but keep in mind that it will not correct the problem underneath the concrete, and it will settle more in the future.

Slab jacking or foam jacking to inject material under the concrete to deal with the soil settlement is the proper way to get the concrete back where it belongs.

Tree Roots

Grinding is a good method to correct fall hazards from tree roots when the tree is still standing. You shouldn't grind a lot of the sidewalk thickness off, however, because it will be more vulnerable to breaking.

If the tree roots have created a large problem, it is better to remove the concrete and reroute away from the tree that is causing the problems.

Frost Heave

Most people are not familiar with this term. Frost heave is the result of water under the concrete freezing and causing the concrete to be pushed up. This could be saturated soil freezing and expanding or even water freezing and filling empty spaces under the concrete.

In this case, you shouldn't use concrete grinding to fix the problem. The empty spaces under the concrete should be filled so that water doesn't have room underneath to puddle up and then eventually freeze.

As you can see, there are different causes of concrete fall hazards and certain situations when it is appropriate to use concrete grinding. It is essential that you hire a professional who knows what the problem is and how to appropriately fix it, or you will be paying for repairs that do not last.
