Grout Tubes

To locate and join the elements together using dowel bars or starter bars, grout tubes are cast into precast panels and elements, creating a void. After the components are positioned as desired, grout is poured into the grout tubes to create a permanent joint.

The spiral grout tubes offered by Grano Direct come in two diameters: Ø40 mm to Ø140 mm for metal spiral ducts, and Ø40 mm to Ø140 mm for HDPE spiral ducts. It is advised to utilize HDPE spiral tubes on upstands and in wetter areas.
