Giant concrete lego bricks?

[SazTam]

There's a local cement company that produces large concrete lego bricks. they used these bricks to form a wall around one of their storage areas where they keep trucks and things.

I'll try and get a couple of pictures today for ya all, but my question is this.

Would these make for a good underground shelter wall? Would I have to put any filling in between the "bricks" and what kind of roof would you use?

The "bricks" themselves are about 3'-4' high and a little bit longer with the "lego" bumps on the top to allow them to be stacked with others.

A great toy for a really, REALLY big kid.

You could always ask the company if the blocks are suitable for underground placement (call it a basement wall). I wonder if they would cave in with time, or would the Lego Bumps keep them where they belong, stacked up nicely?

Y'know what would be even cooler? - if they made them in curved sections, so you could make a circular structure of them. Then any pressure from outside would only strengthen the structure (like an arch, with pressure from above).

Concrete lego blocks. Looks great to me... Even a caveman can do it!

Be careful with them unsupported.....we had a concrete company here that had them as a backstop for crushed rock...the 5 foot wall toppled and killed a guy.

If you use them for an underground struction, you will need to use mortar to help secure them. But really you can't beat poured concrete, it almost never leaks and bricks do leak.

That's exactly what I was talking about.

I just want to be sure that they could stand up to it.. If I had my way, I would build a castle outa these things LOL

They have them with rounded corners and routinely use them for retaining walls and there is enough slop in them that they can put a pretty significant curve in a wall.

Interesting concept, but regular cinder blocks stack just fine and allow you to fill them with rebar and concrete, making them stronger than any dry stacked configuration. That would be my preference for building anything underground or where wall strength and solidity is important.

Concrete does not do well in tension. That's what rebar is for. Cinder blocks always have rebar reinforcement and concrete grouting in structural applications. Definitely consult a structural engineer for underground uses.

Nice bricks, I bet the guys at the Alamo would have loved to have 100 of those things.
