Stone Retaining Walls, Stone pillars, Piers with electric lighting- Michael and his crew build beautiful cemented stone walls in the same fashion they build everything else, to last a long time! Michael often travels to the quarries in upstate New York and Northern Pennsylvania to personally select the highest quality stone for all of his products. Our walls meet (and usually exceed) standard building codes. Michael traveled to Rome in 2000 to gain additional insight into building proud and lasting projects.
