Composite decking is an ultra-modern decking material that you can use to add value to your garden. This decking material put modern technology to use right in your back garden. Composite decking has many features that support this claim. First, it is a synthetic material that is made in a factory. Second, it is aesthetically pleasing because the surface texture has long-lasting pigment. Another reason composite decking put modern technology to use is that you can maintain it with simple tools. Composite decking is also crack resistant. Note that crack-resistant is not the same as crack proof. So, will composite decking crack?

Why Decking Material Crack

There are lots of outdoor flooring material in the market. Wood or timber decking is one type of outdoor flooring material. If you consider timber decking closely, you will know that it can crack easily. This is because timber decking is not crack resistant and crack proof. Cracks are line or light or deep cut that form on the surface of the decking.

 Crack occur as a result of several factors. Heat, temperature change, and stress can make an outdoor decking crack. If you install wood decking outdoors, you will expose it to the elements that we just mentioned. Heat, for example, will make decking expand and contract. That expansion of the outdoor decking material will make the boards split. This splitting will eventually result in cracking.

 When wood decking crack, you will see the lines on the surface. Another reason decking material crack is because of temperature change. Temperature change is similar to heat. When the temperature becomes hot, wood decking will expand. And when the temperature becomes cool, the decking will contract. 

Like heat, expansion and contraction will crack the surface of wood decking. Note that wood decking will crack easily because of its material composition. This is because timber contains natural fibre. So, to make timber decking strong, makers of timber decking treat it with chemicals. Eventually, timber will lose its durability after you have used it for a long time. 

Composite Decking Is Crack Resistant

Unlike wood decking that will crack as a result of temperature change, composite decking will not. This is because composite decking is an artificial product. The manufacturer combines timber by-products with plastic and resin using high pressure to form composite decking. The way composite decking is made one reason it is crack resistant.

 We mention before that crack occurs as a result of several factors. Heat, stress and temperature changes can make decking crack but not composite decking. This implies that when you install your plastic wood composite outdoors, you don’t have to be afraid that heat will destroy it. Heat, for example, will not affect plastic wood composite.

 If the weather is hot, the plastic wood composite will expand easily without breaking. The same applies to temperature change. If the temperature changes suddenly, the plastic wood composite will expand and contract without cracking. The reason for this is that makers of plastic wood composite make it to resist external pressure. The boards are stronger than timber decking, and it is more flexible.

Will Composite Decking Crack?

 Also, the strength to weight ratio of plastic wood composite is high. This implies that plastic wood composite is lightweight and strong. A decking material like composite decking that has a strong surface will be crack proof. But is composite decking crack proof?

Composite Decking Is not Crack Proof

There is a difference between crack resistant and crack proof. When we refer to composite wood decking as crack-resistant, we are saying that it will not crack easily. This means that heat will not make the surface of your plastic wood composite crack.

 Plastic wood composite is built to resist the weather elements; that is why it is crack resistant. But the crack-proof is quite different from crack resistant. Composite decking is not crack proof. The reason for this is simple. Plastic wood composite is like other structural material that can get damaged.

 For example, if you don’t install your composite decking following best practice, it can cause stress to the boards, and they can crack. This is true if you don’t leave the right amount of space between the joists and the boards. That is why composite decking is not crack resistant. So, to make your plastic wood decking last long, you must follow best practice when installing it.


Will my composite decking crack? Wood plastic decking is crack resistant, and it is built tough to resist heat and fluctuating temperature. You have to follow best practice when you are installing your composite decking to avoid cracks.
