Wooden Balau Deck built in Cotswold Downs, Hillcrest

This wooden balau deck built in Cotswold Downs in July 2019 was built primarily to cover the JoJo tanks which were being housed below. There were various challenges in getting the beam across the span around the pipes that led into the tanks but with a few tricks we managed to hang a beam from above rather than secure it from below.

The balustrade was built using balau and marine grade stainless steel wire rope which always works best when you don’t want the view to be obscured when in a sitting position.

There are a few strict rules at Cotswold Downs in Hillcrest with regard to the maximum height of the deck so we had to stagger it and create a split level deck. This resulted in some benches with removable lids for storage and a small flight of stairs to access the lower section.

Wooden balau deck built in Hillcrest

This wooden balau deck was built in Hillcrest. It was built on top of existing slasto. When building on top of a previously laid substrate one can build directly on top of it rather than removing the paving or slasto. It helps with water flow below the deck keeping it drier and thus preventing premature rotting due to excess moisture for prolonged periods of time below the deck.

When building on a substrate like this that has a fall, the width of the joists need to be wedge shaped to accommodate the fall. The pieces of treated timber therefore need to be cut and treated again with an end sealer. We use Kugard which protects any cut ends of timber.

Other than that the deck was a straight forward build. There are various other articles on this site that explain the process we use and the measures we take to make sure the deck lasts longer. Please feel free to browse the site.

This wooden deck was built in Doone Village Retirement Village in Padfield Park, Pinetown.

We used an H3 and H4 CCA Treated substructure with 19 x 68mm balau deck boards. The balustrade was balau pots and capping with marine grade wire rope. It is always better to use wire rope when you don’t want the view to be impeded when sitting on the deck as it is less obtrusive than balau. It isn’t however as safe, as small kids can pull the wire rope open to an opening greater than 100mm. So it should be avoided on decks that are fairly high. The wire rope we use is a 4mm marine grade wire rope with swages. The 4mm is the only one that won’t tarnish.

We used bidim below as the section near the house is low level and one can’t get below to weed or cut any grass that grows below the deck.

We left this one without any decking oil so that it can grey naturally which reduces maintenance cost going forward.

Wooden Deck Gillitts – July 2019

The pics here are of a wooden deck we have just completed in Gillitts. The client wanted an old deck removed, dumped and a new one built with slight changes. It was built in the normal way using an H3 CCA treated substructure and balau deck boards of 19 x 68mm which is the most affordable way to build a wooden deck that will last. The H3 CCA treated pine has a minimum life span of 50 years outdoors in the rain and the balau, being balau, will give one many years of use. The balustrades are all full balau in a vertical picket style and the stairs are open risers in balau. These were slightly wider than normal so as to tie into the posts of the balustrade on the deck.

Deck refurbishment in Kloof

This slideshow requires JavaScript.

This was an old deck in Kloof that we refurbished recently. It had balau deck boards on top of a balau structure. Of the 11 joists that made up the structure only 2 were still in a fair condition. The rest had rotted and we needed to replace them. Please see this article on the pros and cons of using balau as a structure. https://blog.thewoodjoint.co.za/2015/06/21/balau-vs-cca-treated-substructure-in-your-wooden-deck-durban-and-cape-town/

The deck was fairly old (20 years plus). 20 years ago most deck builders used balau as a structure. Over time they have come to realise that a chemically treated pine structure will out last a balau structure because it is chemically treated and therefore it’s behaviour is known. The process of pressure treating is safe and arguably does no more damage to the environment than cutting the purpose grown tree down in the first place.

We ended up lifting all these deck boards, numbering them and replacing them in their same position so that we could use the same screw holes. Rather than sliding new joists in below the deck boards.

The deck boards themselves where quite mottled with black algae but the wood itself was still ok so we pressure cleaned the deck and then oiled it with a penetrating oil. In some pics you can see the difference between coats of oil.  The balustrade is all new as the old balustrade had rotted away beyond repair and had been removed by the client.

Wooden Deck Hillcrest February 2019

This slideshow requires JavaScript.

This client in Hillcrest had this irregular shaped “dead space” that she wanted to deck. Because it doesn’t get much sun, it is always wet and muddy. So we decked it in balau deck boards. The contrast between white paving and wooden decking works very well and the actual shape of the deck makes it what it is. In designing an outside area, one should try to use different materials that compliment each other. Too much wood or too much grass doesn’t work. But a bit of wood, grass and paving works very well and compliments each other.

The challenges were in getting the top of the deck flush with the top of the paving because the corners of the paving are rounded over so unfortunately we had to leave a small space between the board and the top of paving. Although the board is butted up tight against the paving because of the round over a small gap is created. It didn’t however look bad at all and works well. It wasn’t practical to chamfer the end of the deck board as it would have resulted in a very thin sliver that would cause problems down the line.

We decided on leaving the far end straight rather than trying to follow the curve of the rock wall. The gap was then taken up with loose stones flush with the top of the deck.

Another happy client adding to the 99.5% happy rate of our clients.

Wooden Deck Waterfall September 2018

Wooden Deck Durban Waterfall

The video here shows the deck we built from the neighbours yard with the mist rolling down the hill in the early morning. Besides being an incredible sight to see one can see how this garden lends itself to a wooden deck.

The deck was built square off the house towards the boundary fence which over looks The Valley of a Thousand Hills near the Hillcrest area. On either side at the back of the deck there are stairs that lead back to each side of the house. The deck totalled about 80 to 90 square metres.

It was built the standard way we build with a treated pine sub structure and 19 x 68mm yellow balau deck boards. There is a difference between red and yellow balau deck boards. We stock only yellow balau deck boards and use only yellow balau in the building of our decks. The wooden balustrade was our standard vertical picket style balustrade, which is the safest at heights like these, as there are no gaps that exceed 100mm and is therefore compliant in terms of SANS building regulations. The balustrade is at a height of 1.0m. Once you start going higher than about 2 stories it is advisable to build the balustrade at 1.2m for safety reasons.

Stairs can either be built as open risers or closed risers. As open risers one can see through them whereas closed risers the underside of the deck is not visible. From a cost point of view they are the same so the choice would be made on whether or not you want to look below at the structure or not.

All our decks are finished by filling the counter sunk screw holes with a clear epoxy and saw dust mixture and then sanding flat before oiling with a decking oil. There is an option to leave the deck unoiled and to allow it to weather naturally and turn a grey colour.

In the still pic one can how effective lighting is below the capping to illuminate the deck yet not shine in your eyes. These are easy to install in that they are glued below the capping. They are LED lights so very little power is used to illuminate the deck surface.

Balau Wooden Deck, Kloof Durban

 

Here’s a straight forward wooden balau deck we built in Kloof, Durban in October 2018. There were a few angles that had to be cut precisely to finish it neatly but other than that the deck was straight forward to build.

We used an H3 and H4 CCA Treated pine substructure. Because the pine is S5 (Industrial SABS approved grade) it is strong enough to be used as a structure for various building purposes. It is also relatively inexpensive in comparison to other hardwoods that could be used as decking structure. Being S5 it contains a certain amount of knots per square metre and is therefore SABS approved as structural timber. Timber with more knots per square metre is normally used as knotty pine ceiling boards where there is very little structural pressures on the timber. Timber with less knots per square metre is referred to as semi clears or S7 grade. S7 becomes quite expensive and is used as deck boards at times to eliminate knots failing on the deck surface. However because one would need to use twice as much wood (38mm thick) when using pine deck boards, the cost is the same as using a 19mm x 68mm balau deck board at half the quantity of wood. As such we use 19 x 68mm yellow balau deck boards as the surface for most of our wooden decks in Durban. The balau is far more stable being twice as dense and hard with a regular straight grain and as such these balau deck boards don’t twist, cup or bow as easily as pine. With the pine being H3 CCA treated it has a life span of at least 50 years outdoors in the rain and weather.

We added a small flight of open riser steps to this deck to gain access to the garden. These are done in full solid balau using 30mm stock. Normally the stringers are 30 x 215 and the treads are made of multiple pieces of 30 x 102 with cleats fixed to the stringers and the treads are fixed to the cleats. They don’t work that well in pine as the pine becomes very visible throughout and one ends up cladding it anyway which brings the cost back to the same as solid balau. The alternative to open risers steps is to do closed risers where box type steps are made of pine structure and then clad resulting in the riser being closed.

The screw holes of all our decks are counter sunk with a Kalgard decking screw and filled with a clear epoxy and saw dust mixture to match the colour of the wood and then ground flat and sanded smooth prior to oiling the deck. You’ll find other articles on this site where we discuss the pros and cons of using oil vs other finishes available on the market and leaving the deck to naturally grey and weather. If you use the search bar at the bottom right and search for maintenance you’ll find a complete article on deck maintenance.

Wooden Balau Deck Built Waterfall, Durban July 2018

This slideshow requires JavaScript.

This wooden deck we built in Waterfall, Durban was part of a new build at Focus on Ithemba along Blessing Ninela Road, Waterfall. They were building a new boardroom and office complex and part of the design was a wooden exterior deck.

The job was referred to us by Mass Landscapes, Miles Steenhuysen, who was contracted to do the landscaping. His details can be found here.

In consultation with Miles and the project manager we designed the deck so as to flow around this office complex comfortably and aesthetically and within budget.

The structure of the deck was the standard H3 and H4 CCA treated pine. H3 and H4 CCA treated pine is suitable for outdoors decks. H3 has a life span of a minimum of 50 years and correctly treated H4 pine can live in the ground in constant contact with wet soil for a minimum of 20 years. These are guidelines provided by www.sawpa.co.za. The full document can be found here.

We used 19 x 68mm yellow balau deck boards as the surface. There is a difference between red and yellow balau. The red balau, which is a bit cheaper in South Africa, is a lot more porous and less dense than the yellow balau and as a result will absorb and retain water more easily than yellow balau and will therefore probably rot more quickly. We use only yellow balau which is the most cost-effective hardwood for decking in South Africa. It is not correct to assume that treated pine is cheaper than balau deck boards. Please see here for an article on the difference between balau and pine in decking.

The building we were attaching this deck to was not completely square with itself as it was an old building that had been extended. As such one needs to be very careful when building wooden decks against walls that aren’t square or straight. At some point there will need to be a correction to eliminate the problem and it needs to occur where it is less visible. Either the deck can be built square to itself but it will highlight the errors on the building or the deck needs to be built off square to take up any difference between the building and the deck in a place where it is less visible and can be concealed.

Screw holes we filled with epoxy and sanded flat. The epoxy used was a clear epoxy which was mixed with saw dust to match the colour. The epoxy in the screw holes prevents water sitting in the counter sunk screw hole and being absorbed up the end grain which would cause rot to set in more quickly. The deck can be oiled after sanding or left to grey naturally.

Balau pool deck and walkway – Kloof, Durban

This slideshow requires JavaScript.

We engaged with Masslandscapes, a landscaper and garden designer (082 468 3759) on this balau pool deck project in Kloof, Durban to provide a solution for the client who wanted an area alongside their pool that they could utilise more. Before the project started there was the standard paved area of about 1m alongside the pool which was bordered by grass of about 1m and then a flower bed, before dropping down a small bank to the rest of the garden. The client wanted to increase the size of usable area alongside the pool.

Initial designs were to have a very similar layout as per the pics above with a semi-circle sort of node protruding over the bank to gain height and create a look out area overlooking the Kloof Gorge. This proved to be out of budget and would probably have resulted in doubling up sitting area as there was already a large tiled verandah extending out from the living area doors. The final design was settled on which is what you see in the pics.

We needed to excavate some of the garden down and move this top soil for use in another area of the garden. It is always recommended that sufficient space be left below the deck and below the bottom of the lower most bearer or joist to allow enough air flow to dissipate and evaporate any water that settles below the deck. Too often I have seen deck boards rotting prematurely due to insufficient space being left below. Water gets trapped below and the underside of the deck and structure remains damp. I normally recommend at least 150mm below the lowest point of the structure. Once we had enough space below we installed our structure using H3 CCA treated pine. Please see here for an article on the use of CCA Treated pine as structures for decks and balau as deck boards. All cut ends of treated pine, as a matter of course, are re treated with an approved end sealer. When a CCA treated piece of pine is cut it exposes a section that is not treated and can accelerate rot.

Post to ground are set in concrete and installed at the correct distance on the bearers to stop any bounce in the bearer and to provide enough support to prevent the bearer breaking. There are guidelines supplied by engineers for distances that these supports need to be installed. These posts need to be H4 CCA treated pine as they are in constant contact with wet soil.

A lot of this job involved lining up existing paving, pool copings, patio etc. to the deck so the lines were seamless and everything ties in neatly. A walkway, as can be seen from the pics, was created to run alongside the existing raised patio for access to the rest of the garden.

In finishing our decks we fill the screw holes with a clear epoxy mixed with saw dust to match the colour as closely as possible and then grind and sand it flat. Standard wood filler doesn’t quite do the trick and fails with exposure to weather. The filling of screw holes is a very important aspect of deck building. It prevents water sitting in the counter sunk screw hole which would then travel up the end grain of the balau and cause early rotting of the balau deck boards. We use a clear epoxy so that we can match the colour to the deck boards. Off the shelf epoxies are either grey or white in colour and don’t take the saw dust that well to match the colour. Also these epoxies dry very hard. It is better to use an epoxy that is semi pliable when dry. Through seasons of dry and wet, hot and cold, the inside diameter of the counter sunk screw hole will vary ever so slightly. If the epoxy has dried too hard it will cause it to pop out leaving a weak spot on the balau deck board. During maintenance intervals these should be checked and replaced if they have in fact popped.

The deck was oiled using a zero wax content product. The beauty of oil is that it soaks into the wood and therefore cannot peel and flake. A peeling deck is an expensive deck to maintain because you would need to sand off the coating completely to avoid a patchy finish when re-applying the coating. Whereas an oil simply degrades due to exposure to UV over time. A pressure wash and re-oil is all you need to do at maintenance intervals which is relatively inexpensive and easy to do as opposed to sanding the deck again. The oil also allows the natural beauty of the wood to shine through resulting in a more natural wood looking product. Coatings give them the effect of a painted deck especially over time when layer after layer has been applied.
