Wooden Decking in County Londonderry

Wooden decking is an increasingly popular choice for creating outdoor seating areas in gardens. Due to the natural beauty of wood, they can be very beautiful spaces which you can use year round by using additional heating and illumination. Wooden decking is often installed in locations in front of patio or French doors where they can create a seamless transition between inside and outside spaces. Wooden decking can come in any size or shape to complement any area. Curved designs or large areas joined by pathways can produce an attractive effect. Wooden decking is relatively simple to install and causes minimal disruption, especially in comparison to alternatives like patio or paving. It could even be installed over the top of an existing patio. It is critical however to be certain that your wooden decking is structurally sound and able to take the load of any furniture or plants that you would like to use on the decking. There is a choice of varieties of wood that can be used in wooden decking. Usually decking is made of hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will demand maintenance, which typically consists of yearly cleaning and staining for weather proofing, composite woods have become more popular for use in wooden decking because they are more robust and require much less maintenance.

FAQs

If your deck isn’t going to be flat to the ground, it’s a good idea to have some kind of balustrade to avoid any tripping. If the gap between the deck and the ground is less than 600mm, use a 900mm balustrade. If it’s higher than 600mm, the balustrade should be 1100mm tall.

Yes, although you should make sure that the terrace or decking is able to support the weight of a hot tub. Usually, you will need to have a structural survey carried out on the area. Seek the advise of a hot tub retailer or installer about the logistics of installing one at your property.

You might think that building decking on a slope is a no-go, but it’s actually a great way to help you make use of your garden when the ground is sloping. It will provide you with a level surface that you can BBQ on as well as dine alfresco without finding that your meal is rolling down the table. But how do you build decking on a slope? Our guide in the FAQ above, ‘How to build a raised deck’, is the perfect solution – but we’ll break it down here if you just want to get an idea of what’s involved. Dig out the area If you’re laying on soil or turf, you’ll need to dig it out. Dig down and remove all the turf from the area and ensure that there are no weeds or stones in the area you’re going to build your decking on. Since you’re building on a slope, it will be hard to get it level, but dig out to a depth of 50mm and lay weed-control fabric with gravel over the top. Add posts and set with concrete Make holes for posts and add them in, ensuring they’re longer than you need. Make sure they’re level, then fill the holes with a concrete mix to set them in place. Build the outer frame Make sure you always work at the top of the slope when you’re building your decking, and measure where the highest point of the decking will be. Secure the 4 sides of the outer frame and factor in a 2mm fall for every metre of decking so rainwater can run off. Add joists Secure joists along your frame at 400mm intervals. If you get to the last joist and there will be more than a 400mm gap left at the end, add in an extra one for support. Lay your deck boards Screw your deck boards to the joists, ensuring that the deck boards are running in the opposite direction to the joists. For timber boards, you need to make sure you leave an expansion gap of 5-8mm. These steps should give you an idea of whether you want to have a go at building decking on a slope, or whether you want to leave it to the pros.

There are two ways to lay decking on uneven ground. We’ve explained how to build a raised deck in our FAQ ‘How to build a raised deck’ above, and that’s great for uneven ground or sloped gardens. But there’s another way that you can lay decking on uneven ground if you don’t want a raised deck: you can create a level supporting base. We’ll go through the basics here. Materials you’ll need

Paving slabs – old or cheap ones are fine
Timber for the frame and legs
Type 1 MOT hardcore

How to lay decking on uneven ground

Mark out the area as we explain in ‘How to lay decking’. Then, dig to 200mm below where you want to surface of the decking to be.
Add a 50mm layer of hardcore and make sure it’s compact.
Build the decking sub-frame as we describe in ‘How to build a deck frame’.
Lay out paving slabs along the edges and in the centre of the area. This will help to spread the weight of the decking.
Set the decking frame on the slabs, checking for high or low points and adding off-cuts of timber where needed. Don’t forget to sand and seal these off-cuts with decking preservative.
Add your joists and then the deck boards, leaving the recommended gaps of expansion of between 5-8mm.

Building your decking on top of paving slabs is a good way to get it level, but you still may not be able to get as good a finish as if a professional did it. If you’re in any doubt, get in contact with some decking specialists and see what they would recommend.
