?I am working on a design which includes a brick or concret paver walkway to the front door. There currently is a set of precast concrete steps that I will remove. I want to use thermal finish granite steps to replace the precast concrete steps. Has anyone done this before. I was planning to pour a slab below the frost line and then pour concrete walls on top of the slab and fill the cavity with compacted crushed gravel. The steps and landing would then be mortored to the concrete walls. I havent decided whether to use the same pavers on the walk to face the exposed sides of the walls or field stone. Any info would be appreciated.
