Grout Tubes

Grout tubes are cast into precast panels and elements which create a void to locate and connect the elements together using starter bars or dowel bars. Once the elements are placed in the desired position, the grout tubes are filled with grout, making it a permanent joint.

Spiral ducts sold at Grano Direct are available in Metal and HDPE, Metal spiral grout tubes are available in Ø40 mm to Ø140 mm dia and HDPE spiral ducts are available in Ø40 mm to Ø140 mm dia. The Spiral metal and plastic ducts are available in 2.9 M, 5.8 M and custom lengths.
