i dont know all the house bricks i have ever seen are solid. now the bricks that are made for like sidewalks and what not have 3 holes in them. and i have a friend that just had his house rebricked last year.

I am a mason contractor, here in Kansas City MO The holes help us (the masons) work faster. If we lay a paver up a wall it will float( it will move out) and cause the wall to fall. The holes allow the mortar to go somewhere, beside behind the wall. You do not want the mortar to fall behind the wall, it will cause it to bulge out and maybe fall on you, You can use a paver to build a wall but it will take longer, And the holes help bond the brick to the mortar.

There are a few reasons for this. It makes it easy to chop the brick in half widthways & lengthways. Also when you lay the mortar for the next course of bricks it helps to bind them together as the mortar is pushed into the course below as well as into the one being laid. If they were solid you would not get such a strong bond.

The holes hold the cement between the bricks better than a flat brick. They also make the bricks more lightweight.

the bricks with holes are engineering bricks the holes help the structure of the brick and make it stronger they also help the mortar grip the brick together and soak up less moisture than other types of brick the holes also make it easier to cut into the requierd size

One more thing: they fire more uniformly in the kiln.
Just as a donut hole allows fry oil to heat the dough more uniformly from all sides, the holes on the center of the brick allow the firing kiln heat to reach to center of the wet clay.
I would believe that those bricks have higher production yields and less scrap that solids.
That's my story and I'm sticking to it.

It makes them lighter and easier to fire without materially affecting
the strength. Not all engineering bricks have 3: some have none, some
lots of holes about 10mm diameter

It gives more surface area for the cement to bond to thus creating a more solid wall than orinary flat faced bricks.

Two reasons 1 weight considerations 2 allows mortar to finger into holes for better adhesion

They use to be solid. Now it's more about the cost. Less material, almost same strength equals less cost for the manufacture of the brick.
