Concrete is good. It can be formidable. But it can be brittle too, so much so that you might need a bit of concrete adhesive to hold it all together again. Which brings this short introductory anecdote around to one of a number of alternatives to concrete. Concrete that many thought could stand up to pretty much anything these days. Let commercial business practitioners and industrialists be the ones to tell you then that that is just not so.
Concrete may only look strong on the surface but it remains inherently weak. Give it time and without applying any undue pressure, and if you are observant enough, you will see the cracks show through. Fortunately, you do not always need to replace the concrete surface materials in its entirety; it may well prove to be far too costly and cumbersome for you at this time, and can just as easily utilize the above said concrete adhesive.
Which incidentally is made up by one of the most potent of materials otherwise known as epoxy. It only looks soft from the outside but believe you me, it is a whole lot stronger than concrete even. It most certainly does not crack. And of course you would need something a lot more forceful to scratch the surface if you will with your bare nails. But why would you want to do such a thing? Why would you want to ruin something that looks good on the outside?
And works very well indeed from the inside. Why not just replace the concrete altogether and just put in an epoxy flooring system for once and for all? For any active commercial business owner and/or industrialist, this should at least be a long-term objective going forward.
