RDS concrete was subcontracted to lay the foundation for a new garage. Roberto had his guys lay the gravel base for the concrete directly on wet fall leaves and grass, they did not excavate the site to eliminate the organic material and very little research will tell you that this will cause the concrete to crack. When I first asked him about this he told me that he did excavate the site and then when I told him that I could prove otherwise his response was, 'So sue me', and then to cuss me out. Roberto is very unprofessional in both his work ethic and in his response to legitimate concerns. RDS concrete does poor quality work and I recommend not using their services if you want your pad to look good for more than two or three years. read more
