What Thickness of Decking is Best?

When it comes to creating the perfect outdoor oasis, one of the most important decisions you’ll make is choosing the right decking material; but have you ever considered the thickness of your deck boards? The thickness of your decking plays a crucial role in its overall strength, durability, and performance. In this guide, we’ll explore the different factors that influence the best thickness for your decking. Whether you’re a seasoned DIY enthusiast or someone considering their first deck project, join us as we dive into the world of decking thickness.

Understanding Wood Decking Thickness

Wood has long been a popular choice for decking due to its natural beauty and versatility. The standard thickness for all types of wood is typically 1 inch (25mm). However, depending on the type of wood you choose, opting for a thicker board can provide added sturdiness. Let’s take a closer look at some key considerations:

1. Type of Wood

Different types of wood have varying levels of strength and durability. For softer woods like pine or cedar, opting for a thicker board can help compensate for their lower density and provide better stability over time. Thicker boards are less likely to warp or sag under heavy foot traffic or adverse weather conditions.

2. Span Length

The distance between joists or supports underneath your deck plays a significant role in determining the appropriate thickness for your decking boards. Longer spans require thicker boards to ensure structural integrity and prevent excessive flexing or bouncing when walked upon.

3. Load-Bearing Capacity

Consider how much weight your deck will need to support regularly. If you anticipate hosting large gatherings or placing heavy furniture on your deck, choosing thicker boards can help distribute weight more evenly and prevent sagging or damage over time.

4. Aesthetic Preferences

Thicker decking boards can create a bolder visual statement and provide a more substantial feel underfoot. If you’re looking for a deck with a strong and robust appearance, opting for thicker boards can contribute to the overall aesthetic appeal of your outdoor space.

Exploring Non-Wood Decking Options

While wood decking has its charm, it does require regular maintenance and may not be the best option for everyone. If you prefer a low-maintenance and highly durable decking material, non-wood alternatives like RealGroove™ polymer deck boards are an excellent choice. Here’s why:

By understanding the factors at play and weighing your options carefully, you’ll be well on your way to creating a beautiful and long-lasting deck that enhances your outdoor living experience.

Why Are There Gaps Between Boards?

If you’re considering building or renovating a deck, you may have noticed something peculiar – gaps between the boards. At first glance, this might seem like an oversight or a design flaw, but in reality, those gaps serve a crucial purpose. In this comprehensive guide, we will delve into the reasons behind these gaps and why they are essential for the longevity and functionality of your decking project.

Understanding Swelling and Expansion

Before we dive into the specifics of decking gaps, it’s important to understand the concept of swelling and expansion. Wood is a natural material that responds to changes in temperature and moisture levels. When exposed to heat or humidity, wood tends to absorb moisture from its surroundings, causing it to expand. Conversely, during dry conditions or colder temperatures, wood loses moisture and contracts.

The Role of Gaps in Decking

  1. Accounting for Swelling: One primary reason for leaving gaps between deck boards is to account for swelling or expansion during condition changes. By leaving approximately 6-8mm gaps (dependent on the moisture content at installation), you allow room for the wood to naturally expand without causing damage or warping.
  2. Preventing Water Accumulation: Another vital function of decking gaps is facilitating water runoff. When it rains or when you use water to clean your deck, these spaces act as drainage channels, preventing water from pooling on your deck’s surface. This helps protect your deck from potential water damage and ensures its longevity.
  3. Aiding Air Circulation: Proper air circulation is crucial for maintaining healthy wood decking. The gaps between boards allow air to flow freely underneath the deck, helping to prevent moisture buildup that can lead to rotting or decay.
  4. Minimizing Dirt Accumulation: Without adequate spacing between boards, dirt, debris, leaves, and other particles can easily become trapped, leading to an unsightly accumulation. By maintaining gaps, you provide a clear pathway for debris to fall through, making it easier to clean and maintain your deck.

Considerations for Board Size

It’s important to note that the size of the boards used in your decking project also plays a role in the spacing decision. Wider boards tend to be more affected by weather changes than narrower ones. This means that if you choose wider boards for your deck, you may need to leave slightly larger gaps between them to accommodate their potential expansion or contraction.

Additional Benefits of Decking Gaps

Aside from their functional purposes, the gaps between deck boards offer some additional benefits:

  • Enhanced Aesthetics: Strategically placed gaps can add visual appeal and create a sense of proportion and balance in your deck’s design.
  • Improved Ventilation: Proper airflow beneath your deck helps prevent moisture buildup, reducing the risk of mold or mildew growth.
  • Easier Maintenance: With well-spaced decking, cleaning becomes more straightforward as dirt and debris can be easily swept or hosed away.

Wrapping Up

The presence of gaps between boards in decking projects is not accidental; it is a deliberate and essential aspect of installation. These spaces allow for natural wood expansion, prevent water accumulation and dirt buildup, aid in ventilation, and contribute to the overall aesthetics of your deck. So when planning your next decking project, remember to embrace these gaps as valuable contributors to the longevity and functionality of your outdoor oasis.

Non-slip decking: What is the best wood to use?

Non-slip decking is a great way to make use of your garden all year round. Not only can it be customised and personalised, but it also allows you to create alluring and safe outdoor spaces. Many people choose garden decking to create functional areas for families whilst some just prefer it to a traditional garden.
Softwood and hardwood have their own individual qualities so it’s important to consider what the space will be used for when it comes to choosing the best timber for decking. We’ve compiled a comprehensive analysis of the two, to help guide your decision.

Softwood and hardwood


Hardwood timber comes from trees that are slower to mature. Oak and Beech are just two examples of hardwood trees you might find in the UK. They’re made up of a more complex structure and will lose their leaves in autumn and regrow them in the warmer months. They’re more often found in temperate countries where they will only shed occasionally.

Softwood trees are much faster growing and in great supply. They’re coniferous and retain their needles all year round. Some examples are Pine, Redwood, and Cedar.

Price difference


Price will most likely be one of the biggest deciding factors when it comes to choosing the timber for your non-slip decking. Due to its fast-growing nature, softwood is widely available meaning it has a lower price than hardwood. Hardwood’s complex structure makes it more difficult to process. When combined with how long it can take a hardwood tree to grow, you can justify the higher price.


Other pricing factors may also influence your decision. For example, softwood decking will need treating or staining. It will also depend on where you are building your garden decking and on what type of surface. Will you need to prepare your ground? There are extra costs to consider but, ultimately, adding non-slip decking to your home can add value to a property.

Durability and ease of maintenance


In terms of their durability, softwoods are generally less dense which makes them more susceptible to moisture and rot. However, if the wood is treated and sealed before the decking installation, you can improve its resistance to bad weather. Bear in mind that softwood decking will need annual maintenance to ensure it keeps its look and durability. Most softwood timber decking boards will have a 15-to-20-year lifespan.

Whilst hardwood decking boards require less maintenance than their softwood counterparts, it’s still advisable to do so. Softwood or hardwood decking boards are still timber. This natural material is likely to weather and age naturally, so staining, oiling, and cleaning your deck as needed will help to keep it looking fresh.

Hardwood decking is known for its longevity. Woods like Yellow Balau and Cumaru are renowned for their water resistance and their stability and can last for up to 50 years. For the most part, it can be left alone and will uphold its robustness. The average life span for a piece of hardwood decking is from 30 to 50 years.

Look and feel


Look will no doubt be a priority when choosing the best non-slip decking. A garden is an extension of a person’s home. So, the look and feel of it needs to reflect that. As well as coming in a variety of different shapes, sizes, and heights, the wood you choose will have the most noticeable difference.

Hardwood decking is more comparable to having an indoor floor outside. It’s typically smoother due to its more complex structure. The shades tend to be dark with a much warmer tone. These can be anything from a brown tone to a darker, golden brown. Hardwood decking is also unlikely to need staining unless you’re after a different look for your garden.

Softwoods are typically a much lighter shade of timber decking. When treated it has a pale green tinge to the wood. Just like a tan, after a few weeks outdoors, it will turn more golden. If you choose to use a stain, then you can make the wood much darker, even closer to a hardwood shade. With softwood, you have more options to customise it.

When you should use each


It’s good to think about what you will be using your garden for when considering the best timber for decking. Will it be exposed to the elements? Will it be a high-traffic area? For example, if you have a swimming pool or a hot tub, hardwood generally has better moisture resistance.


How heavily will your deck be used? For the average household, softwood decking is perfectly suitable and durable for an average amount of use. If your deck will need to withstand heavy foot traffic and will see lots of use, then consider hardwood.
