Why Not to Use Hollow block

Hollow blocks is a backyard industry in the Philippines' and is not regulated. Hence, mostly the quality is poor. Drop a block on the floor and it breaks in many pieces. they are bot recommended to build your Dipolog house and lot.

Hollow blocks are nothing more than stones that you stack between the columns like Lego so you can make an opening in it to place the windows or doors; They cannot carry loads, the columns do that). They have no other function than being a wall. It's the cheapest way to make a wall but they are weak and they have to make the wall 4 inch or 6 inch thick to become strong enough. Consequently the wall becomes heavier than necessary. And since the wall consists of weak hollow blocks mixed with strong reinforcement bars, there is 'the weakest link factor' that makes the (too heavy-) wall prone to forces that want to find a way out and results in cracks.

The strength of a hollow block wall is much less than poured concrete walls.

Hollow blocks also need to be plastered (covered with a separate thin layer of a cement/sand mix) which is time-consuming and it might crack; exposing the steel reinforcement bars which will rust.

When using blocks the columns (posts and beams) carry the second floor and/or your roof. Hence the weight of your house put pressure only on the little footings of the columns and you have to be pretty sure that your soil can hold that.

Now compare that with poured Concrete Walls which are strong enough to carry the next floors and roof. The weight of your house put pressure on the walls columns and beams. That's a much bigger surface.
