Though both solid wood and engineered wood can be installed on a concrete sub-floor, the processes are quite different from each other. Solid wood is produced from a single plank of wood which can be reactive to both temperature and humidity changes which is capable of making the wood expand or contract. Hence, the different approach to solid wood and engineered wood flooring installation on concrete. Here, we’ll discuss how you can lay solid wood on your concrete.

First and foremost, you’d have to determine the method you’ll use to attach the planks to the floor. Is it floating whereby you only have to lay the wood flooring on the concrete after fitting the right underlay? You can also go for the most popular installation method which is gluing your floor with a flexible wood adhesive (to be applied to both the boards and the sub-floor). Or perhaps you’d prefer to use the traditional method of nailing the boards to the concrete (the nails will be covered as you lay the subsequent planks and the groove locks with the tongue).

After making this decision, you’d have to ensure that the sub-floor is well prepared for the installation. This implies checking the wood’s moisture content (mustn’t exceed 7 to 8 percent). Also inspect the floor to ensure its neat, if not, clear out the dirt or debris and make sure the surface is flat to avoid post-installation problems.

In the event whereby you discover a high moisture content, you’d want to acquire a damp proof membrane. This will not only enhance the floor’s stability, but also prevent shrinking or warping of the wood due to changes in humidity or temperature.

It is crucial to note that the preparation of the sub-floor is equally as important as the laying of the planks as this can go a long way to improve the durability and strength of your floor. Click here to learn more about wood flooring.

1. Place a post in the corner of the frame you created with the pegs and string. Measure and mark out 100mm from each side.
2. Dig out this soil to a depth of 700mm (watch out for cables or pipes). You should have a 300 x 300mm hole. Repeat for the other 3 corners.
3. Using a brick bolster, split a concrete block in two. Put a section of the block in each hole.
4. Get a length of post longer than you need and place one in each hole. You can cut it down later.
5. Create props on each post to hold them in place until you’re ready to add a cement mix. Check that they’re level. When you’re happy that they are, secure them in place with a concrete mix, making sure you create a slope in the concrete so that rainwater runs away from each post. When the concrete is set, remove the props.
6. Create a string line around each corner post and find the centre point between each. Place a timber batten at each point, ensuring that they’re not spaced any more than 1500mm apart.

1. Working from the corner where the deck will be at its highest above ground level, measure and mark on the post where the highest part of the frame will be.
2. Measure from the far side of one post to the opposite and cut sections of joist to size. Line up a piece of joist with the mark you made and temporarily secure it. Factor in a 2mm fall for every metre of decking so rainwater can run off.
3. Secure the frame to the other corner post, ensuring it’s at the right level. Do this for every side of the outer frame.
4. Using 100mm coach screws with washers hanging on the end, secure each end of the four sections of frame.
5. Mark out where the centre of the support posts will be and secure all of these posts to the frame, except the centre post.
6. Add your central support joists. These should run in the same direction as the deck boards will run. You’ll need to measure from the inside of the frame on one side to the inside of the frame on the opposite side. Attach the joist in the same way as you did for the other posts. Repeat so the centre post is in between two sections of frame and secure the posts with concrete.
7. Trim down all the posts to the correct height using a saw.
8. Add your weed-control fabric and weigh down with gravel across the entire area.

1. Measure 400mm from the centre of the outer frame and mark a line. This will be where the first joist is positioned. Repeat at 400mm intervals down the length of the frame – if the last one will be more than 400mm, add another joist to create enough support.
2. Attach a joist hanger to each end of the joist.
3. Place the joist in position so the centre lines up with the 400mm spacer mark.
4. Secure using external grade screws once you’re happy that the joist is flush with the frame.

• Have a step tread width of 900mm – if you don’t want them that wide, they should be no less than 760mm
• Add a central step riser to stairs wider than 900mm to prevent them buckling
• Add a step depth (the vertical distance between each step) of between 150 and 180mm if building your own riser, so the steps are at a comfortable depth

• Step treads (the actual step themselves)
• Step risers
• Coach screws
• Deck screws
• Saw
• Drill

1. Make sure the ground where you want to put your steps is level and firm. If it’s not, consider laying concrete or paving slabs to provide a secure surface for your steps to sit so they don’t sink.
2. Grab some joist off-cuts and cut them to the same width as your step treads. Attach them to the step risers at the top and bottom using countersunk coach screws.
3. Place the steps against the sub-frame of the deck; if you’ve put slabs down for support, make sure the steps sit in the middle of them. The longest edge of the stair riser should be on the slabs, and the short edge against the deck. Drill pilot holes through the step and sub-frame joist, then screw the step to the sub-frame with more coach screws.
4. After drilling pilot holes, screw the treads into the risers at each end with deck screws.
5. If you don’t want gaps between each stair, you can add joist off-cuts or deck boards. Measure the height and depth of the gap, then screw the off-cut or board into the step riser with two screws at each end.

• The shed doesn’t cover more than 50% of the garden
• It’s not in front of your house
• The shed is single-storey with eaves no higher than 2.5m and the overall height is no taller than 4m for a dual-pitched roof, or 3m for any other type. If it’s located within 2 metres of your property’s boundary, it mustn't be more than 2.5m high
• There’s no veranda or balcony
• The floor area is no bigger than 15m² - up to 30m² may be covered under Permitted Development if other conditions are met
• The shed is for domestic use only by those who live in the property and there’s no sleeping accommodation – that means you can’t run a business from the shed unless you apply for planning permission

• If you live in a listed building, you’ll need Listed Building Consent before you can build a shed in your garden
• If you live in a conservation area or similar, the maximum area of ground covered by outbuildings, pools and enclosures situated more than 20m from any wall of the house mustn’t exceed 10m² if they’re to be considered as a permitted development
• If you own a piece of woodland, you must seek planning permission for any permanent structure
• In Scotland, you’ll need planning permission if any part of the shed comes within 1m of a neighbouring property or is more than 2.5m high
• In Northern Ireland, there are rules about how close your shed can be from a road that passes by the back of your house. It’s best to check for clarification

1. If you’ve not got an overhang or it’s a fixed deck, fit starter clips along the outside edge of the frame and secure with screws provided with the composite decking. If you are working with an overhang, put the first board into position not exceeding 25mm. If you’re adding a fascia, put an off-cut of board under the overhang so you know it’ll be flush with the fascia.
2. Pre-drill all fixing points, measuring in 30mm from the edge of the board. Secure the board to the joist below with composite decking screws.
3. Slide a hidden fastener clip in so it sits within the groove of the deck board. It needs to be in the centre of the joist to keep the boards secure and ensure an expansion gap of 6mm. Tighten the clips until just tight, and repeat so there’s a clip at every joist.
4. Add the next board, ensuring that the fastener clips sit within the groove – make sure you don’t force it. Repeat step 3.
5. Continue steps 3 and 4 until you’re at the final board, which you should secure in the same way as you did the first.

• Tongue and groove timber boards
• Boards for the ledges and braces, at least 20mm thick
• Nails
• Hammer
• Saws, including a circular saw
• Chisel
• Mallet

1. Cut your boards to size If you can’t buy boards at the right height and width for your door, cut the boards to length using a circular saw. Don’t forget to sand and treat any cut ends with timber preservative. Lay out the boards in the best arrangement for your shed door, with the inside of the door facing up.
2. Arrange the ledges and braces On most shed doors, you’ll probably need 3 boards across the back of the door to form the ledges. The ledges keep the door straight and keep the boards of the door together. The braces are the parts of the door that slope down to form a ‘Z’ shape between the ledges. Ensure that the braces are sloped up from the bottom and middle hinge to stop the door from sagging as the timber expands and contracts in the weather. Once you’re happy with the arrangement, mark the spots on the boards where they will meet and cut out of the housings using a chisel and mallet.
3. Put the door together Use clamps to pull the boards together and hold the ledges and braces in place. Nail from the front of the door through the boards and ledges to fix them. Secure the ledges and braces with screws; you may want to pre-drill and countersink holes to prevent the wood from splitting. Remember to treat them with preservative if you do.
4. Fix the shed door hinges Make sure you measure carefully before attaching the hinges, ensuring you know where the pin sits in relation to where the door opens.
5. Treat the door and add locks and handles Apply some wood oil, like linseed or teak oil, to help prevent water damage. Then add locks or handles to your shed to help keep it secure.
If you’d rather leave it to the professionals, there are plenty of specialists that will be able to make a shed door for you, or even put up an entire shed.

Installing wooden flooring is a quite simple process, however to get it right the first time, there are very essential preparations that must be made. These includes determining the site is in the best condition before installation, removal of all floor coverings and underlay for a more stable and durable installation and incorporation of the right expansion gap of about 10mm to 12mm which would be maintained around the floor’s perimeter.

Wooden floor fitting can be done on two types of sub-floor - Concrete and Plywood. To install onto concrete, you can follow the guide below:

• Incorporate flexible wood on concrete adhesives.

• With the help of a 3mm toothed trowel, spread above 2 board widths of adhesive along the starting wall sub-floor, beginning at a corner of your room.

• Position the first row of flooring into the area that is glued using the tongue facing opposite the wall.

• Put 10mm spacers against the wall to see to the consistency in expansion gaps.

• Make sure the joints are at a minimum of 150mm apart from the first row when fitting the second row.

• Utilize pre-cut smaller boards if you’re to start a new row with staggered joints.

• Continue with this nailing method and make sure the 10mm expansion gaps are consistent around the floor’s perimeter.

To install onto plywood, you can follow this guide:

• Make use of a porta-nailer.

• Position 10mm spacers against the wall - parallel with the installation direction.

• Fit the first row using the tongue facing opposite the wall and with the help of the porta-nailer or flooring nailer.

• Lay the second row and make sure the short end joints are at a minimum of 150mm apart from that of the first row.

• Utilize pre-cut smaller boards if you’re to start a new row with staggered joints.

• Continue with this nailing method and make sure the 10mm expansion gaps are consistent around the floor’s perimeter.
