7 Common DIY Concrete Project Mistakes

A sense of accomplishment is great, that’s why most homeowners opt for DIY projects rather than hiring experts. However, not all DIY projects are straightforward. For example, a concrete pouring project requires experience, in-depth knowledge, and special tools.

If you’re inexperienced, there are many things that can go wrong and cause you to spend more. In this article, we will discuss the most common mistakes that can cause your concrete project to fail.

Incorrect Height

It is best to measure the concrete’s final height even before starting your concrete pouring project. This will allow you to pour at the right level and prevent lopsided concrete. If the height is incorrectly measured, you may need to redo the entire project, which is time-consuming and more expensive.

If you’re unsure of how to measure the exact height of the slab, it’s more practical to consult a professional concrete contractor.

Forms are Uneven

Forms are critical in every concrete pouring project, it can determine the overall look of your finished concreting project. Make sure that concrete won’t spill over unwanted areas. Constructing forms and ensuring to place them in the correct areas can be time-consuming, but who wants to end up with uneven concrete?

Putting Incorrect Amount of Water

The ratio of water to dry concrete is also critical. Wet concrete shouldn’t be runny, chunky, or dry. It should be smooth. However, most homeowners add too much water when mixing concrete because they believe that it is easier to work with soft concrete. Take note that water weakens the concrete. This means, adding excessive water can compromise the strength of the concrete.

Failure to Use Reinforcement

Another common DIY project mistake is failing to use reinforcement to the structure. Even though concrete is a very strong material, it lacks tensile strength. Therefore, it’s still prone to cracking. Adding reinforcement will hold the concrete together and improve the strength of concrete.

Slippery Surfaces for Walkways


A smooth surface looks sleek and appealing. However, slippery surfaces are dangerous and can lead to accidents. Make sure to consider the concrete finish and add some texture to the surface if necessary.

Incorrect Use of Steel Mesh Reinforcement

One of the most popular concrete reinforcements available in the market is steel mesh. It’s widely used because it can be bent to fit columns or walls. Steel mesh should be put in the centre of the concrete, not in the top or bottom.

Pouring Concrete During Bad Weather

The ideal weather should be warm and dry when pouring concrete. This is often overlooked but the temperature of concrete will determine if the concrete will reach its maximum strength potential.

Hot weather will cause water to evaporate quickly. Remember that during the curing process, the concrete should stay wet for a couple of days. On the other hand, rainy days also pose a challenge because excess water can skeet the cement and water ratio.


If you planning to have a DIY concrete project, you must take into consideration the most common mistakes that cause concrete failure. Disregarding these common mistakes will make you spend more than you expected.
