PRECAST CONCRETE
PIPES
Colossal installs reinforced concrete pipes using roller suspension with high strength, high durability concrete and produces large diameter vertical cast pipes. This process is used worldwide and is acknowledged to be ideal for concrete pipe manufacturing. All the manufacturing processes are done under carefully controlled conditions using advanced technology and equipment.
These processes provide flexibility for the manufacturing of tailormade wall thicknesses for special load and strength requirements. If corrosion problems are anticipated, Colossal has several methods of prolonging the life of the concrete pipe. The substitution of the siliceous aggregates with calcareous aggregates results in the extended life of the concrete pipe.
An HDPE liner can alternatively be added to the bore of the pipe to prevent the sulphuric acids from coming into contact with the concrete surface.
