Marble is a natural stone. Though polished, it's still porous.

If you're mostly concerned about having a non-slipping effect when wet... then don't seal it. Any kind of mild cleaner will eat away the sealer anyway and will eventually "etch" the marble.

Actually, it's the mild acids that do that, but acids are in almost every cleaning product and also occurs naturally so just walking from outside to inside will eventually make your marble mosaic... non-slip.

can have seed planted under it or through it after it is put down. I have used it before and it is better than mulch because it can't move and unless you get a monsoon type of rain it stabilizes the soil. That is the same sort of mat that the DOT uses when they do road construction and they don't have a ground cover down yet.

samples of what happens not only if you build incorrectly but it shows how in this case the outside bows out due to the settlement of the structure.

The same thing can happen inside a wall like a staircase that is next to this area.

This was an addition in which another contractor installed TGI joists without properly running a engineered band joist or adding any supports to prevent sagging of the floor. Those of you that are in the business will get a kick out of just how bad they constructed this building.

You will also see some of the repairs that we did to help stop the settlement. We could not jack the addition up, but at least we stopped if from getting any worse.
