we wanted a pool installed in our backyard,but realized there were so many boulders it might be impossible,our pool builder introduced us to rocksplitters inc.we talked price and found it was more affordable than blasting,and no fire dept,no permits no pre blast inspections,just a lot of hard work by rocksplitters we now are swimming in our beautifull backyard oasis.thanks very,very much rocksplitters.the SHIELDS FAMILY of hopkinton mass.
