Concrete Precast Block

Coast Precast Block are durable, industrial purposed, rebar reinforced, and are being used for tank supply and services companies to place tanks with stability. While there is a multitude of applications for these block, our primary customers have been in the Propane Tank industry because of the rebar reinforcement and the 5,000 psi strength concrete. These block are more than capable of handling the weight and abuse of transportation, being tossed on to the ground and placing large propane tanks on them to keep the tank stable.
