I get a very strong north wind so don't think a fence would hold. Basically I want to raise a wall to block the winds and peeping boars. I got a quote for a wall but it's so expensive it involves drilling the existing concrete. Maybe a stackable thing that would work the same. I read somewhere in Netherlands that they have these stackable bricks that are easy to DIY, but not sure.

Looks like hollow concrete blocks with some sort of tile on it? if so it's a lot of work/manpower and time. How high do you want it? Forget about DIY stuff if you don't want to repair your own vehicle. It's a monumental task if you never did construction before. Maybe if you want to let someone do the DIY bricks then it could be cost efficient.

I’d like to double its current height, so around 1.5 meters total. The first contractors suggested just a fence to simplify the work. The second suggested a real wall built next to the current one. The real wall is nice but the construction method is too complicated since it involves breaking the concrete foundation. I suppose it is to prevent the walls falling during earthquakes.

1.5m is not high at all. If it's already concrete blocks, drill the existing cement inside the blocks add rebar risers and put a few more rows of blocks.

Right? apparently none of the two contractors I asked went by this route. The 1st contractor that wanted to build a fence said they could use rebar risers but for 3 rows only. 3 rows would put it like a meter at most? That's not enough.

I suppose they are inexperienced. I have learned a long time ago it's not because they have a contractor licence or business licence that they are competent. There's quite a wide range of skill level.

Some are outright scammers, they take a deposit saying they need to buy supplies and you will never see them again. In that case it's a criminal offense however some do such a bad job they pocket most of the money and since they did a little bit you have to take them to court because it's a civil matter. In both these cases don't expect to get your money back. Always pay by the percentage of job completed.

If there are empty cells it will be even easier. Also take a look at the lateral reinforcement.

Looks like u got a bit of a retaining wall there. As suggested id just build a fence either behind the wall or if the wall is solid, on top.

If your concerned about windload, use something like these galvanized posts. They are designed for hurrican force winds, dont rot and are incredibly strong. You can use extra thick lumber for even further rigidity when building, we've done a few like this and made them over 8ft high and 3" thick as a acoustic barrier for sound.


Generally any wall over the height you have existing will need engineering depending on the product used. Most times a solid poured concrete wall with rebar is the strongest best option. From what your describing to achieve, a fence constructed as I've described would more then suit your requirments and be a lot more budget friendly.

I created a new thread for this topic.
