A few variables need consideration.
We will not build block steps if there are more than 3 risers.
We will not build block steps on houses less than 2 years old.
In 2012 we had to rebuild block steps that we built in 2010. The steps had 5 rises just an enormous amont of weight. They settled. We did everything right. The house was 4 or 5 years old at the time.
It took a week to tear down and rebuild. Had to buy 3 tons of gravel. Had to buy one pallet of block. Had to buy adhesive. Plus fuel to get to the property for 5 days. Lesson learned. Never again. We fixed it. I feel good, we did the right thing. Customer is happy. Never again will we do monsterous steps like that. If client insists then they can sign a waiver accepting no guarantee.
Bestthingto do is completely excavate the overdig zone. That is expensive and does not happen in minutes. You'll prove yourself out of the market. Nice composit steps are way cheaper and they don't settle.
