Best Practices Guidelines for Concrete Construction

Pipes that have been improperly cleaned may cause blockages where old concrete has set and may cause bleeding and segregation. Defective couplings, gaskets, or weld collars also can result in the loss of grout. Another thing to look for are bends that are too short, too sharp, or too numerous, all of which increase concrete pumping pressure.
