Indoor Wooden Balau Pool Deck Built in Estcourt

Here’s an indoor wooden balau pool deck we built in Estcourt KZN recently.  The client had been doing some renovations on his house and had enclosed the pool with brick walls and windows resulting in an indoor pool.  He wanted a wooden deck around it to finish it off nicely.

Careful consideration was needed to ensure that any water from the pool could quickly drain away so as not to remain wet beneath the deck boards for too long.  Of course with an outdoor deck any rain water or pool water evaporates quite quickly and isn’t of that much concern.  Being indoors however this water can get trapped below the deck for some time resulting in premature failure of the timber.  Although the timber is H3 CCA treated, and as such can live outdoors with periodic wetting, it cannot remain wet constantly.  H4 CCA Treated timber is more suitable for damp conditions such as constant contact with wet soil.  But a fair amount of water on an ongoing basis is not a good idea.

In this instance the builder had done a great job in creating a small fall on all four sides of the pool so that any water dripping or splashing on the deck would fall back into the pool rather than sit below the deck.

The job was relatively easy as there was very little difference in distance between the walls and the sides of the pool.  If the wall is not parallel to the pool then it will result in a wedged shaped deck board either up against the wall or the pool.  To counter this one must “fan” the deck boards by making the gaps on one side 1mm smaller than the gaps on the other side effectively gaining 1mm per deck board.  After 20 deck boards you will gain 20mm to make up any difference.

In fibre glass pools one might also find that the edges of the pool are not straight.  Run a fish line along it to see if it bulges in or out and find the straightest side to start your decking.  If it does bulge then you will need to overlap your deck board on the pool side slightly to cover that and keep the deck boards straight.

A simple single deck board as a fascia board on the inside of the pool finished it off nicely.  It was oiled with a deck oil and this deck will require very little maintenance or re-oiling as it is indoors and won’t get any sun.

Wooden Deck and Stairs Built in Umhlanga, Durban

This wooden deck we built for a client in Umhlanga, Durban was a suspended wooden deck about 2.8m off the ground. The idea was to make use of the flat concrete roof as a deck because the views from up there are of Durban Anchorage where ships anchor before proceeding to Durban port.  The views also extend all the way down the Golden Mile of Durban.

We didn’t want too many posts going to ground as the area beneath the wooden deck is still used as an outside patio. So we built our substructure using H4 CCA Treated pine in a 50 x 228 size rather than the normal 38 x 114. This way we could span our wooden joists of the deck across a longer distance without the need to support them below with another beam, and therefore posts. We attached the one end of the row of joists with a T joint to another 50 x 228 beams which carried the one side. The other side of each joist was hung in a custom-made galvanised steel joist hanger. The result was that our entire substructure was in one plane rather than having the joists sitting on top of a beam. It allowed us to keep the ceiling height of the deck higher, without having to increase the height of the top of the deck surface. These pine wooden joists were later sanded and sealed to make them look closer to the balau we installed on top of the pine.

The wire rope balustrade was fairly straight forward and we extended it past the deck on to the concrete slab flat roof.

The challenges in this wooden deck came in building the stairs. We had a fixed height to work with and a limited lateral distance in which we had fit all of our treads and risers whilst still keeping our risers and treads compliant. To add to this we had a window we had to pass to get down quick enough in our stair case in order to miss the window, plaster band and plumbing on the side of the house. The only way possible was to split the staircase into three flights with two landings where the flights turned at 90 degrees. We also had to split each landing into three windings in order to gain an extra two risers per landing in order to finish the stairs where they needed to finish. We adjusted the tread depth to shorten our treads and therefore total lateral distance to basically “sqwish” then all in. Normally we use 3 pieces of 30 x 102 balau for treads with two 5mm gaps between boards resulting a tread width of 316mm. We ripped the middle 30 x 102 to 50mm to reduce this lateral distance whilst still remaining compliant at 264mm but gaining some lateral distance in order to squeeze them all in. We finished it off with balau deck board cladding in order to cover all the pine structure. The job took time but it was well worth the wait. Stairs that look nice, work nicely and remain compliant.

It was all finished with an oil based sealer which penetrates the wood rather than drying on the surface.
