I’m a single female in my mid 30s with no real diy skills (but not afraid of hard work) and no family within 2 hours. I got a builder in yesterday to take up decking which he did, and then left. When I rang him he said that he won’t be able to come back for 6-8 weeks. Underneath the decking it turns out there is concrete which will be perfect when I clean it. The problem is that there is a ridge running around the concrete slab: it has kind of a stony texture. I’m just wonder If I could break this myself With a hammer or is there More to the job? I really don’t want to wait 6 weeks if this is a job where I can do it myself. Any advice appreciated.
