I need to make a step flush in my new extension as shown in the attached dodgy sketch. The recess is about 40mm deep, 700mm wide and the step about 150mm high (I need to measure). I plan to use c24 timber to make it level but my question is what to fix it with? Engineered flooring is going on top so I really don't want it to move at all. Are resin bolts overkill? I was also thinking anchor bolts? Counter sink the heads.
Thanks
