One of the biggest hesitations people have when it comes to choosing concrete for their projects is that it cracks over time.

While this practical, durable material is one of the strongest goods on the market, the forces of time and nature will eventually cause it to crack–especially if it’s been installed by a non-reputable company.

But why does concrete crack, and is there anything that will prevent this from happening?

These 5 mistakes are some of the most common causes of concrete cracks.

1. The concrete dried too fast

Faster is not always better. If your concrete mix doesn’t have enough water in it, it will dry too quickly and crack prematurely. Depending on the project, it should take at least a few weeks, maybe even a month, to dry completely.

2. Your contractor put too much water in the mix

Poorly mixed concrete can create a range of problems. Just like having too little water in the mix can cause it to crack, so can having too much water. Water must combine with the concrete at just the right pace so that it can cure and set properly. 

3. Control joints weren’t used

Your concrete must be able to properly expand and contract in different temperatures, otherwise it’ll crack. Control joints are made specifically to help your concrete move about without breaking. 

If your contractor doesn’t use these joints, there won’t be extra room for the slab to adjust its size with the changing temperatures, and it will end up cracking due to its internalized pressure.

4. It was too cold when your concrete was poured

Just like the amount of water affects concrete’s hydration process, so does cold weather. When the temperature drops too low, concrete won’t be able to cure correctly. In these situations, the pour will either need to be postponed, or the subsurface will need to be warmed before pouring. 

5. Your concrete is too thin

Concrete that’s too thin is extremely susceptible to cracking. The proper thickness of your concrete will vary based on its purpose. For example, a driveway that’s meant to support vehicles needs to be thicker than a sidewalk that is not.

Improper concrete thickness is one of the top reasons why DIY concrete projects fail. When taking on a massive project like this on your own, it’s easy to miscalculate the weight your concrete will be expected to bear and the subsequent thickness necessary. Unfortunately, this will result in severe premature cracking.

At Port Aggregates, our contractors have 40 years’ worth of experience built into their pours. Our beautiful concrete has been trusted for decades with good reason. When you hire our professionals, you can say goodbye to premature cracking and rest assured that your slab has been installed properly. Contact us today to request a quote!

Concrete is much more than just a place to park your car or a foundation for your home.

When starting your next project, it’s important to be aware of your options. This material can really be quite beautiful if you know what to ask for.

The possibilities are endless, but today, let’s take a closer look at exposed aggregate concrete.

What is exposed aggregate concrete?

Over 100 years old, the exposed aggregate technique quite literally “paved” the way for decorative concrete. 

The name pretty much says it all. In this type of concrete, a thin top layer is intentionally removed to expose the aggregate underneath. The exposed layer can include sand, gravel, quartzite, or crushed glass.

Gravel is most commonly used, and a variety of different sizes are available to give you the desired texture that you want. See example below.

Benefits of exposed aggregate

Exposed aggregate concrete offers infinite benefits. The most glaring advantage is its gorgeous appearance and satisfying texture. It adds a natural element to any area, and the three-dimensional surface is completely customizable. 

Another advantage to this type of decorative concrete is its increased traction. Rough surfaces like these are ideal for helping you keep your footing–even when the surface is wet or icy. It can even be customized to stick out at certain levels, if you so desire.

One of the main reasons why exposed aggregate is so popular is its price. It’s one of the least expensive types of decorative concrete available, and is an affordable alternative to standard, drab concrete.

How to care for exposed aggregate concrete

Like any other type of concrete, exposed aggregate offers immense durability and is very low-maintenance. 

Proper care includes regular sweeping or rinsing off with a hose. It should also be resealed every couple of years. Fortunately, the color of the aggregates will not fade over time, and it’s actually the easiest type of decorative concrete to keep up with.

Repairs (if necessary) are quite simple, and exposed aggregate can last for decades if properly cared for and installed by professionals. At Port Aggregates, our expert concrete contractors have decades’ worth of experience built every pour. Contact us today to request a quote!
