I'm stuck! We have this crumbling retaining wall that needs to go. THought it would make a great DIY. ALSO, we have settled solid concrete steps, need to be replaced or "Fixed" or covered up with new stonework. Can you guys offer some ideas? I thought I could do a retaining wall 2.5' by 10 with a corner going into the sidewalk. THe local stone place (Big supplier) stated htat Veneer onto the cinder block in our cold climate (Syracuse NY) is not a good idea that low to the ground. Moisture will seep into the mortor and start cracking and falling off. is that really true? I thought there was a mortor that resists moisture issues? YOu help is greatly appreciated to help solve some of my confusion.
