Got a query about our composite and aluminium decking products? See if it's been answered already in our extensive FAQs

We have compiled a list of decking product FAQs to help our customers learn more about our various ranges – including composite decking, fast-fit composite decking tiles and our A2 fire-rated aluminium decking. Simply scroll through each tab to find the product you want and to see if your composite query has already been answered.

Can our decking be painted?

Yes. However, we would strongly advise against it. Our highly sophisticated, maintenance-free decking is designed to resist all weather conditions, so it won’t fade or rot over time, negating the need for a paint job.

Can Dura Deck be stained?

It doesn’t need it – all of our products are engineered to resist mould and rot, so you won’t need to go through the hassle of treating it every year.

Can it be used indoors?

Yes. The durability and versatility of WPC decking makes it one of the few outdoor materials that can be used inside. However, there would need to be a solid base for it to sit on, which is harder to achieve indoors than it is outside.

Can composite decking be put directly on the ground?

No. Our decking cannot be laid over an existing surface – instead, we need to lay a sub-surface for the composite to sit on, ensuring maximum results.

Will composite decking rot?

No. Unlike traditional timber materials, our decking is specifically designed to resist water damage and rot.

Does Dura's decking get hot?

As a trusted composite timber decking supplier, we can’t guarantee that your boards won’t get hot. What we can guarantee, however, is that regardless of how hot they get during the summer, they'll never warp or bend.

Does it scratch easily?

No. The unique composition of our decking means that it won’t scratch or chip by reasonable means, making it perfect for furniture.

Will composite decking burn?

While it's not 100% inflammable, composite decking has a much higher fire resistance than traditional timber decking. Our Dura Deck Resist boards have a Class B fire rating, which means that they won't ignite or drip, making it safe for a range of applications.

How much decking do I need?

To find out how much decking you need, take a measurement of the width and length of your desired area and multiply the two numbers. This will give you the total area of the space. For example, if the length is 3 metres and the width is 4 metres, you'll need 12 square-metres of decking. Alternatively you can just use our decking cost calculator.

How do I clean my boards?

It couldn’t be easier to clean Dura Deck; its water- and stain-resistant technology means it only takes a wipe or a scrub to remove any impurities.

How long will it last?

All of our Dura Deck product has a 25-year service life, but with good maintenance it could well exceed that.

How do I fix my boards?

You don’t: we do it for you! All of our decking comes with a minimum 10-year warranty, so if you ever need a repair or replacement, all you need to do is call.

Are composite decking boards slippery?

No. Unlike purely plastic or vinyl alternatives, our decking is designed to prevent you from slipping on it.

Is it waterproof?

Yes. The blend of plastic and wood that makes up our Dura Deck means that it is 100% waterproof. This means that, unlike timber, it won’t swell or warp when the weather gets too rough – it’ll remain perfect year in, year out.

Is Dura Deck hollow?

Not always. Like other suppliers, we offer a varied range which includes both hollow and solid options. Solid decking is usually more durable, while hollow boards tend to respond better to changes in the weather.

What is Dura Deck made of?

Dura Deck is made from a unique combination of timber and plastic, giving it the feel and look of the former, but the durability of the latter.

Does composite decking expand?

No. While the boards can be laid to account for some expansion, our composite decking boards are heat and water resistant, so they won't warp, swell or expand with changes in the weather.

Is composite decking cheaper than wood?

Board for board, timber is the cheapest material you'll find for your decking project. However, this will need constant maintenance, repairs and replacement over its lifespan, whilst composite decking has an estimated life-cycle of 20 years, without the need for constant care. Based on a deck size of 12 square-metres, we estimate that composite decking could save you up to £3,000 over its lifespan.

How many decking tiles do I need?

If you are decking a square or rectangular space, simply take measurements for the length and width of the area. Multiply these numbers (e.g. 3x3m) to get your m2 measurement. Each Dura Deck Tile Resist measures L605mm (2ft) x W305mm (1ft) x D25mm meaning you can cover 1.10m2 (11.8 ft2) with each box of 6 tiles. Each individual tile is 0.18m2 or 1.96 ft2. So it’s not complicated to work out how many decking tiles you need. However, you might prefer to use our handy composite decking tile calculator which will tell you exactly how many boxes to order and what they’ll cost. A good rule of thumb is to order 10% more tiles than your measurements say you need, to allow for any wastage.

Do decking tiles need a base?

The tiles have an integrated base with drainage holes and don’t need to be installed on top of joists or bearers. The only requirement for laying Dura Deck Tile Resist is a flat and relatively even surface. Dura Deck Tiles won’t interlock when laid on uneven surfaces, so you must be sure to fix any underlying issues before starting. If your existing patio area is prone to weeds or organic growth, you may choose to lay a weed control fabric down first before laying your tiles.

Do composite decking tiles attract wildlife?

Unlike traditional decking, which involves the installation of a substructure, our decking tiles can be laid directly on the ground. This means there is no chance of wildlife such as rats or mice getting underneath the decking tiles and making a home – which can be a troublesome issue for some timber decking owners.

Can composite decking tiles be cut?

If you’re looking to deck a small, flat area that’s square or rectangular, and you’ve calculated your measurements correctly you shouldn’t need to cut any tiles. That said, if you’d like to deck around specific obstacles or if you have an L shaped decking area, you may prefer to use a jigsaw or mitre saw to cut the last few tiles to your required dimensions and guarantee a perfect fit. If you’re not confident in using hand tools, you can always add a few decorative stones or aggregate to quickly and neatly finish off any leftover areas, such as around a drainpipe.

Can you put decking tiles on grass?

We’d advise not to lay the tiles directly onto grass or bare earth directly as a long term solution as within a few weeks you’d be likely to see weed growth or new grass coming up between the surface planks of the tiles. In addition, if your garden doesn’t have good drainage, then any significant rainfall could cause the tiles to sink over time. The tiles do make a great option to lay onto grass for temporary events such as BBQs or parties though, and can be easily lifted and stored inside a shed or outhouse between uses. If you do choose to install over grass as a permanent solution this would be at your own risk and with the knowledge of how well drained your soil is. If you do decide on this route, we’d recommend you lay a weed control mat over the area first.

Are composite decking tiles slippery?

Dura Deck Tile Resist has been extensively tested for its resistance to slipping, even in wet conditions, and has what is known in the landscaping industry as “low slip potential”. Unlike traditional timber decking, this means that our composite decking tiles have in-built anti-slip features such as an armoured and textured surface, making them safe for use in all outdoor environments. Due to their unique composition, they do not absorb any significant water, so you can be confident that they’ll be safe to walk on in all weathers.

Do you supply internal corner decking tile ramps as well as external ones?

The Dura Deck Tile Resist range includes edge ramps to provide a neat transition between the decking area and the adjacent floor surface, and corner ramps which help finish off external corners. If your deck design requires internal corner edge ramps, you can create these yourself, but we would only recommend this if you’re an experienced DIYer with the necessary jigsaw or mitre saw and a good understanding of cutting and measuring. If you want to do this, you should first remove the straight edge plank from its in-built base, cut it to the 45 degree internal corner, then cut to length to suit the external corner base (which is shorter than the straight edge) and then repeat for the opposite side. You can then reattach to the plastic base. If you require further technical support, please get in touch.

Can I install decking tiles over gravel?

We would always advise that the surface you place the tiles onto is a hardstanding, existing patio that you wish to cover over or other area of solid ground. We would not recommend installing over gravel as this may affect the ability of the connecting tabs to interlock fully and may cause movement of the tiles.

The area I wish to tile is circular and not rectangular. Can the tiles be cut to shape?

This product is designed as an easy DIY decking area for customers who want the look of traditional decking but without the hassle. If you have good DIY skills, you can use a jigsaw to cut the deck tiles to fit around an obstruction such as a downpipe, but we wouldn’t recommend cutting the tiles to create a circular area as this would impact the stability and performance of the product, reduce the point of interlocking and would not enable you to use the edge or corner ramps to complete your design.

How do I make sure my ground is even?

The easiest way to check that your ground is even before laying the tiles is to use a flat surface such as a large book, and then place a spirit level on top to check the ground is even. If the spirit level indicates the ground is uneven, you may want to level it out or flatten it out before starting, as the firmer the ground, the better the results.

Do you offer a fitting service?

No we do not offer a fitting service for the decking tiles as they are designed as a DIY product for those who don’t have the skills or confidence to install traditional decking and the associated substructure frame themselves. The composite tiles interlock by clicking together and can be placed onto any flat and level area of your garden (such as over an ugly patio) to achieve new seating and lounging areas with ease. If you’re not confident in installing deck tiles yourself, it would be a simple project for a handyman to complete using the measurements and quantities provided by our online Deck Tile Calculator.

Can the tiles be removed easily for treatment of weeds or other corrective action?

Yes, the tiles can be easily lifted by carefully removing each section, making sure not to damage the interlocking tabs so they can be laid back down. If your area is prone to weeds, you may want to treat the area with weed killer and/or lay down an anti-weed membrane prior to installation. This will also stop any grass growing through the tile base.

Do the tiles move around once laid?

No, the weight of the composite timber tiles once interlocked creates a stable surface that has excellent anti-slip properties versus traditional wooden decking. The tiles are also wind uplift tested, meaning they should not dislodge in gusty winds.

Does Dura Deck Tile Resist come in any other colours?

In the UK, the tiles are available in Pebble Grey and Mahogany colours which provide a great contemporary look to any outside space. We don’t currently offer other colours in the range, however our 3.66 metre long composite decking boards do come in 9 great colours if you prefer to opt for traditional decking instead of fast-fit tiles.

Can I lay the decking tiles on top of grass?

We’d advise not to lay the tiles directly onto grass or bare earth directly as a long term solution as within a few weeks you’d be likely to see weed growth or new grass coming up between the tiles. In addition, if your garden doesn’t have good drainage, then any significant rainfall could cause the tiles to sink over time. The tiles do make a great option to lay onto grass for temporary events such as BBQs or parties though, and can be easily lifted and stored inside a shed or outhouse between uses. If you do choose to install over grass as a permanent solution this would be at your own risk and with the knowledge of how well drained your soil is. We’d recommend that you lay a breathable weed control matt over the area first though.

Why is the Dura Deck Tile Resist range better than other tiles on the market which are cheaper?

Where do we start?! Dura Deck Tile Resist is the result of years of development and has a patent pending and EU Registered Design that’s unlike anything else on the market. For a start they are double the length of most cheap decking tiles, so you can cover more ground faster, and achieve the look of real decking and not a dated square chess board effect. The Dura Deck Tile Resist surface is made from composite timber which features recycled hardwood content that’s environmentally sustainable. The 360° armour wrapped around each individual plank on the tile uses the latest co-extruded technology for greater protection and enhanced slip resistance. Cheaper products you might see in your local bargain store use a loop and pin interlocking system to connect each tile which is very fiddly and liable to break when fitting. Out decking tiles use a reliable dove-tail interlocking system that locks the tiles together firmly and prevents them for moving around once installed. If you’d like to view all the other reasons why we’re the best on the market, why not check out page 4 of our decking tile brochure?

Does the price per box of decking tiles or ramps include delivery?

Yes. All prices quoted include FREE delivery to mainland UK, except for the Scottish Islands, Northern Ireland, Isle of Wight, the Isle of Man and the Channel Islands. If you are not mainland UK, please send us a quick message and we can advise on likely delivery costs. Please note that whilst delivery is free, if you change your mind and wish to return the tiles to us, this would be at your own cost and the tiles would need to be in a resell-able condition in their original packaging, so do unpack them carefully when they arrive.

Are the tiles suitable for Hot Tub Decking?

All hot tubs require a firm, level base which is capable of supporting the weight of the hot tub, the water and the bathers with no movement. Dura Deck Tile Resist is a decorative covering for existing hardstanding areas and could work well as a surround for an area with a hot tub, as the individual tiles are easily removable to ensure accessibility for pump maintenance etc.  However, they will not support the weight of a hot tub being placed on top, so you’ll need to ensure that what is underneath the tub itself is a structural sturdy, flat surface such as a concrete slab that will be able to hold a lot of weight without collapsing. If in doubt, you should consult your hot tub retailer for detailed load calculations for when the tub is filled and at full capacity, or employ the services of a qualified structural engineer.

Can I put tiles over old decking?

Yes you can overlay the tiles onto your existing decking area for an instant refresh, but be aware that for them to lay flat and interlock correctly, your old deck should be level, with no twisted or warped boards. If your existing decking area and substructure is very weathered, then be sure to lift your tiles at regular intervals to check the area underneath is not rotting away, as if the substructure fails, then your tiles could fall into the void below.  Dura Composites holds no responsibility for any deck and substructure failure whilst using the tiles in this application.

Of course if your old decking fails, you can easily remove the tiles and relay them in an another area of your garden, such as on top of a concrete or hardstanding area, or simply remove the old deck, level and prepare the area with appropriate drainage and/or a weed membrane, and lay the tiles directly onto the ground.

Does balcony decking need a fire rating?

Yes. With the ban on the use of combustible materials on high-rise buildings set to be extended to cover all buildings with four or more storeys (or +11 metres in height) under plans the government put out to consultation in January 2020, our fireproof aluminium decking is the perfect choice for your balcony, terrace or roof garden, thanks to its market-leading A2fl-s1 rating. When considering your balcony decking material, please ensure that you choose a supplier whose baclony decking fire testing has been conducted in conjunction with the correct flooring test and installation method on a horizontal plane. Don’t trust any supplier who tests to one method (i.e. on a calcium silicate backing board) and then recommends that you install to a completely different method!

What kind of structural performance is required for aluminium balcony decking?

It’s important to choose a decking material that has undergone stringent testing to guarantee its effectiveness and performance under both point load and crowd loading in accordance with relevant building codes. Look for data that meets the requirements of the most recent 2.0kN point load @ 0.5% deflection (L/200) BS 6399-1:1996) standard.

Does aluminium decking get hot?

No. Due to its unique composition, our aluminium decking boards stay cool even in hot weather, making them a great solution throughout the year. This also means that the boards are barefoot friendly, and safe for children and animals.

Is aluminium decking suitable for outdoor flooring and balconies?

Yes. While aluminium decking is primarily used for terraces and balconies, it also makes a safe, cost-effective option for public spaces and general flooring use. it is 100% recyclable at the end of its life, making it a sustainable and eco-friendly decking option.

How to clean aluminium balcony decking?

Aluminium decking doesn’t stain, fade or rot, so will only require minimal cleaning throughout its life cycle. All you’ll need to do in order to keep your balcony decking looking great is give it an occasional wipe or scrub.

How to replace balcony decking?

Our aluminium decking comes with a 25-year warranty and a long service life, so you’ll likely never have to replace it. It’s also 100% recyclable.

What is the life expectancy of Dura’s metal decking?

Our aluminium decking has an expected service life of over 25 years – but under normal residential conditions it will likely last much longer. The best part is that our metal decking boards are recyclable, so they can still be put to good use even if you decide you want something different and choose to replace them.

How many components make up this decking?

Our decking comes with three separate components for easy installation. The innovative tongue-and-groove design means that they slot together with ease, reducing install time and saving costs. Furthermore, our boards are ready to install as soon as they arrive on site.
