Frequently Asked Questions
Q: What is the white residue on my Stairs?
A: This is known as Efflorescence, it is the process of dissolving an internally held salt in water. The water, with the salt now dissolved in it, migrates to the surface where the water evaporates leaving only the salt.
Q: What will be the height of each stair rise in my retaining wall?
A: This depends on the size of retaining wall block chosen to build the wall.
