Precasting concrete is an alternative to cast in place concrete. Precasting structures allows for better quality control of the concrete often times produced indoors for optimal curing conditions. Precast assemblies in the field are very efficient often returning projects to service in less than half the time of cast in place. Precast structures however have to be built in segments due to weight and scope. A couple examples are concrete pipe and manhole riser sections. These jointed segments need to be treated with joint sealants and waterproofing wrap treatments. Our line of Blackhawk Hawk-Seal joint sealant, Blackhawk 5401 Pipe Joint Mastic and Blackhawk Hawk-Wrap external joint wrap are essential components to create a watertight connection.
