This wooden sun deck we built in Westville Durban was designed to try to maximise outdoor space. The house we built it at had very little outdoor space as it was situated on a steep plot. You can see from the pics that before we built the wooden sun deck, the garden had only a small area of about 1m around the pool on the front side of the garden. There was then a steep concrete staircase down the side of the house going to the back garden. The back garden was however not very usable as it was far from any entrance to the house. So the idea here was to build a wooden sun deck that extended from the slasto of the pool area to meet the far side of the house. It was about 48m² in total floor area and was surrounded by a wooden balustrade in a picket design. We left the existing concrete stair case in place and built the wooden sun deck so that one could use this existing stair case. Hence the U Shaped deck.

We also had to split the wooden sun deck into two levels as the area by the pool was a little lower than the area where it met the existing concrete deck. So we had a split level deck with a small step up of about 180mm. 180mm is always a good step height or riser height.

The posts beneath had also been lined up so as to avoid being placed in the middle of the stair case. Even though the outer posts were some distance from the bottom of the stairs, if we had placed them where they would normally have gone (i.e. equal distances from either end) then it would have spoilt the line of sight as one was walking down the stairs. So they were shifted slightly left and right to miss the line of the stairs.

We also had a garden shed beneath the front edge of the deck so we had to build around that which had had a new roof built on it and waterproofed. When building over waterproofed structures one cannot drill through the torch on as it will results in leaks beneath. You need to then build on either side of it or use thicker beams and joists to be able to span them further apart.

In the pics on this article you can also see the horse shoes we used to support the beams on the walls. Instead of dropping posts to ground you can simply attach the beam to the wall by cutting a horse shoe using the same timber as the beams. The bottoms are always cut to 45° for both neatness and to avoid having sharp corners jutting out. This also applies to the ends of main beams.

We treated our cut ends with Permaseal, an approved end sealer used to stop rot or insect damage to cut ends of CCA treated timber. This was necessary in order for us to activate the 50 year guarantee that the supplier provides on the CCA Treated pine substructure. There are a few articles on this blog that go into detail about this and what is required in order to activate your 50 year guarantee.

Wooden Sun Deck Repairs – Durban

Wooden sun deck repairs Durban

Besides our main activity of sundeck building in Durban, we also maintain and repair sundecks.

Wooden sun deck repairs need to be performed from time to time and the sooner they are attended to the better. If a wooden deck is constructed correctly these repairs can be kept to a minimum, but from time to, factors beyond anyone’s control can result in repairs having to be made to your wooden sun deck.

The pics alongside show how we repaired this wooden sun deck in The Bluff Durban. It had been built on two posts of balau that were about 2.6m high. One of the posts had, for some reason, sunk slightly, soon after building the deck, but had since stopped sinking. The deck was about 7 years old and the subsiding had apparently occurred in the first year after building it. We were happy that it had stopped subsiding so we were able to use the existing posts to correct it. The client didn’t want us to install a new post because there was a lot of concrete and paving around the base which would have resulted in digging that up in order to set a new post and remove the sinking one.

The reason for it subsiding could have been that there were no horizontal nails inserted into the bottom of the post before it was concreted in. Nailing 6” nails into the wood at the bottom of the post and then setting concrete around the post will stop this sinking as the nails will act as anchors in the concrete. Without them the post can very easily move through the concrete and sink. Another reason could have been that the ground was not completely compacted and the whole level of the ground at that point sunk. Being The Bluff, the latter is quite probable as The Bluff is essentially one large sand dune and is continually moving.

Because the post had sunk about 50mm the top of the deck was no longer level. We jacked the deck up using two scaffolding jacks, one on top and one below, and a 50mm pipe cut to size. We placed a nice flat piece of 50 x 228 timber below to give us a level base and a larger foot print that the scaffolding jack provided.

We took the pressure off the post by jacking it up until both scaffolding jacks became tight up against the ground and the beam respectively. We secured the scaffolding jacks to the beam and the base plate using screws so that it could not slip off once we started lifting the deck. Once the pressure was off the post we cut the post in half and then continued to jack the deck up to our required height checking periodically until the top of the deck surface was again level. Once it was level we installed two pieces of galvanised angle iron on opposite corners of the post using coach screws.

We then filled the cavity we had created in the post, of about 50mm, with a block off wood as a fail-safe in case the angle iron or coach screws ever failed. This way the post could not drop down, in the event of the angle iron failing, as the block would prevent that.

Although it doesn’t look as nice as it would have had we replaced the entire post, it was much easier to do, less expensive and eliminated the problem of digging up the concrete and paving.
