Balau Timber Pool Deck, La Lucia, Durban

Here’s a wooden pool deck we built in La Lucia, Durban recently. In the gallery above you can see pics of the old deck and then pics of the new deck. The old wooden pool deck had started to rot at critical points. The reason for rot in many wooden decks is that the screw holes are not plugged, water gets in and travels up the end grain of the wood resulting in rot at the screw holes. Water travels more easily along the end grain of wood than the side or face grain. So it is important to seal the end grain as far as possible to prevent this. In the case of the end of deck boards the water never really gets trapped so it can drain away quickly enough to prevent rot. However in the case of a screw holes water collects in the screw hole and then has enough time to be absorbed by the end grain before it evaporates. As a standard procedure we fill counter sunk screw holes with epoxy to prevent this from happening.

The epoxy we use is clear so that saw dust can be mixed with it to match the colour as closely as possible. It is also slightly pliable. In hot and cold weather, wood expands and contracts, as does most materials. If you consider a screw hole. The sides of the screw hole will expand thereby closing the screw hole or making it smaller. Whatever is in the screw hole, as a plug, will also expand. So if the screw hole is getting smaller and the plug is getting bigger it makes sense that whatever is in there will likely try to “pop” out. Using a slightly pliable epoxy can reduce the chance of this plug popping out. Hence the reason for not using solid wood plugs cut with a plug cutter. The epoxy should be pliable enough to take up the expansion of the screw hole but hard enough not to degrade due to weather conditions.

We used 90mm balau deck boards on this deck. They are slightly more expensive but some clients prefer them to the standard 68mm boards. Being a wider board one needs to secure them on both shoulders on each joist rather than just a single screw in the middle of the boards, as is the case with a 68mm board.

The job took a bit longer than I would have liked because the substrate that we were building on top of, paving and concrete in this case, were quite uneven so we had to shim and trim joists to get the top of our joists level, flat and at the desired height to be flush with the inside of the house. The jacuzzi cladding was also quite tricky because we had to build a removable structure so that one can access the front of and below the jacuzzi. One side of the jacuzzi step is also wider than the other one so the corner required some fancy carpentry work in order to get the boards to line up and match. I’m glad I took so many pics of the deck before we removed it so that we could copy it exactly.

There were also some wedges that we had to cut along the front edge as the tiles and existing patio were not square to the wall we were building our wooden deck up against. Whenever the existing buildings are not square there is always some sacrifice one needs to make and the trick is to get it least visible to the eye. In this case the client wanted the wedges rather than cutting the tiles or bringing the front of the deck past the line of existing buildings.

Wooden Deck, Umhlanga, Durban

Here’s a wooden decking project we completed in Hawaan Forest Estate, Umhlanga, Durban. There were two houses right next door to each other so it was a bit easier on the pocket when it came to travel to site. The whole job was quite big too, in excess of 200 square metres of coverage, so it was worth the travel from Home Base in Waterfall, Hillcrest.

House 1 consisted of a fairly large deck of about 80 square metres. It was an interesting deck to build in that it was built flush with the tiled covered patio, extending to the pool, with steps as wide as the deck leading into the garden. It incorporated a fire pit with step benches on three sides set slightly away from the pool. The front of the steps were clad so that beneath the deck was not visible. We met our deck boards at a 45 degree angle on the vertical cladding.

There were various smaller decks around the front of the house and the courtyard consisted of a steel frame and steel gate clad in balau deck boards. There was an interesting deck on the first floor of about 7 square metres that is accessed through a door on to the roof top. It is bordered by three sides of planter boxes surrounded by balau.

The garage doors were 6m wide and 2.7m high. The frame was made of steel and deck boards were used to clad it. It resulted in it being quite heavy but complimented the front of the house by following through with the wood cladding design so typical of Hawaan Forest Estate homes.

Along the front of the first floor are steel sliding screens of 14m x 3.1m high. The decks and courtyard screens were all done in 19 x 68mm balau reeded deck boards whilst the sliding screens on the first floor were done in 19 x 30 balau slat. In order to get a 19 x 30 slat we ripped a normal 19 x 68 deck board in half to 30mm wide. These were then attached to the steel with a 20mm screw from behind so that no screw holes are visible from the front.

Most deck boards are reeded on one side which allows water to dissipate more easily between the deck board and joist, so we had to source non reeded deck boards for this application. If it had been reeded the grooved side would have been visible from either the inside or the outside. Non reeded deck boards are not that common, but they are available, and it is cheaper to rip deck boards to 19 x 30 than to buy 20 x 30mm slats.

House 2 had a much smaller pool deck of about 25 square metres. It was fairly intricate though in that the deck had to be tucked underneath the wall on one side and beneath the tiles of the pool fascia. The patio above the pool had a fall to it to allow water to run off, so the edge of the deck could not be level, otherwise it would have resulted in a stepped join between the wooden deck and the patio. There are also a few smaller decks surrounding this house and it too has a 13m long by 3.1m high sliding screen system in steel with balau 19 x 30 slats.

I will update these pics above once other contractors have completed their areas of work to give you a good idea of what is possible in timber decking and screening.
