Within 2 days I have now also built back my pool terrace. The pool terrace was laid in the garden around the pool a few years ago. Partly the terrace was detached because the pool is on a slope.
I also documented the construction of my BPC pool deck here on the blog .
In the article“Project pool terrace – building the free-standing substructure for the BPC planks” and in the article“Project pool terrace – building the substructure and laying the BPC planks” you can see more details.
Pool remodeling – The pool terrace is rebuilt
As I wrote in the last post, on the deconstruction of the steel wall, our pool is undergoing a major rebuild.
The old oval steel wall pool is to be turned into a masonry pool made of shell stones. The new pool gets a proper staircase and a sunbathing area in the water.
The steel wall pool is surrounded by retaining walls on the long sides. These retaining walls of shuttering blocks will form the new pool exterior walls. At the curves, I had stabilized the steel wall with a wall cast from concrete. This retaining wall must now be removed because the pool is being enlarged.
Part of the pool terrace is built on and against the eastern retaining wall. Of course, I have to build back the terrace before removing the retaining wall. I have to be careful and cautious because most of the materials can be reused.
Dismantle WPC planks
The pool deck was originally going to be extended over my gabions to the plateau of the garden kitchen. But since I still had to do some preparations there, the terrace ended so far directly in front of the gabions.
The first terrace plank was screwed directly into the substructure with stainless steel screws. But all other decking boards I have fixed with a special system.
For this purpose, small staples are inserted between the planks. These clips grip into the groove of the plank and pull the plank down as it is screwed into place. In this way, 2 planks are always attached to a transition point. A system which I like very much because it is stable and yet invisible.
Using a cordless screwdriver and the appropriate Torx bit, the clamps were opened and the planks were removed one by one. I labeled the planks and stored them neatly. These are to be reassembled later in the correct order.

Damage to the substructure of the pool terrace
Dismantling the decking boards is relatively time-consuming but not particularly difficult. The screws in the retaining clips between the decking boards were absolutely fine. No rust interfered with the removal.
The substructure, on the other hand, was anything but intact. In my video“Experience report – 3 years BPC | WPC pool terrace in the slope – conclusion” I had already described my experiences after 3 years BPC pool terrace.
However, with the removal of the decking boards, the full extent of the damage to the substructure became apparent.
The substructure was made of 100×100 mm larch wood. On this beam I applied a 60×40 mm counter-battening.
The counter-battening was then doubled up with WPC construction timber. And it is precisely this WPC construction wood that has disappointed me insanely.
The hollow timbers were broken. Small gaps and cracks had formed everywhere – even though the installation was frost-proof. The screws have come out of the WPC in some places, leaving more holes.

Deconstruction of the substructure – Even more problems
After taking down the WPC construction timbers, I was able to take care of the larch counter-battens and the large beams. But here, too, unexpected problems arose.
The counter-battening was fixed to the large wooden beams with adjusting screws. The adjustment screws are completely countersunk in the counter-battens and can then be precisely aligned by turning the screw up and down. With these adjustment screws I was able to level the deck.
The screws are well loadable from the top. However, the counter-battening to the side is very unstable. I had additionally fixed the 60×40 mm timbers with rafter purlin anchors.
In this way, the substructure was perfectly aligned in height and extremely stable.
Unfortunately, the adjustment screws were not rust-proof. When unscrewing the screws, I had already destroyed 3 bits after the first 5 screws. I had not experienced that before.
The screws themselves were still completely intact and would have held the deck for many more years.
In the end, I cut the screws with my angle grinder. This was not a perfect solution, but it was always practical.

Video of the deconstruction of my pool terrace in the garden
I will be following the entire conversion of our steel wall pool to a stone pool with my camera. In my playlist for the project pool you can watch the whole process in peace.
I have recorded the dismantling of the WPC/ BPC pool terrace in the video Pool rebuild – dismantling pool terrace | BPC planks | substructure | pool technology.
Deconstruction of the wooden beams under the pool terrace
The dismantling of the 100×100 wooden beams was then much easier again. The wooden beams were bolted directly to the concrete retaining wall on the one hand and on a load-bearing beam structure on the other.
Among themselves I had connected the beams with angle connectors, perforated plates and large wood screws. This construction was extremely stable and yet, with the right tools, easy to disassemble.
To protect the beams from moisture, the installation was carried out in U-post beams. Thus, a distance of approx. 5 cm to the concrete floor was always ensured. On the wall I used small 5x5cm rubber mats as spacers.
Conversion pool terrace in the garden – How to proceed?
It took me a good 2 days to remove the pool deck. Now I can take care of removing the concrete retaining wall on the east side.
Once this wall is removed, the rebuilding of our pool can begin.
