Reply To: @ waterproofconcrete – Is

@ waterproofconcrete - Is that correct that the crystals will only grow when a crack forms and that they will only grow to fill the crack and not continue expanding beyond the original dimensions (more than a couple percentage points anyway)? Even after decades?

The crystals that would be on the outside of the structure would likely have been triggered during the original creation of the concrete item. Since the crystals seem to activate when cracks on still on the micro fissure level, the relative weight of the concrete structure shouldn't increase dramatically, even in the event of a critical failure sized crack you're still looking at only a small increase in weight. Compared to the weight you'd gain from taking on vast amounts of water, I think this technology has some merit.

There seem to be a few companies pushing this same kind of tech. I saw one demonstration last year where the concrete actually bent and flexed at more than 90 degree angles on a 6' sheet while maintaining integrity. Amazing feats of engineering.

Live Well!
