Ditch lining

TILTEX 10 was recently specified to replace 100 mm concrete as a permanent and temporary erosion control solution for a flood diversion and drainage canal, as part of a 200 acre rail and road infrastructure logistic precinct hub in Sydney. The area was subject to severe rain events and required a durable flood diversion drainage lining solution.

TILTEX 80 MPa Compressive Strength, 16.1 MPa of Flexural Strength and 5 meter wide roll size outperformed other GCCM and conventional concrete options.

To line the 10 meter wide flood diversion canal, our 5 meter wide rolls enabled us to design and install 16 sets of panels longitudinally and 10 panels equilaterally where the canal curved, thus requiring only 480 linear meters of seaming. GCCM’s with 1,1 meter wide rolls would require 336 panels and 3 360 linear meters of seaming plus an additional 16 800 screws as part of their seaming process. This amounted to 540 m2 of cementitious material for seaming compared with 72 m2 of material to seam with TILTEX 10 with no screws required, just thermal welding. The savings benefits included a faster seaming advantage, less material wastage, less risk of leaks and a faster construction schedule. TILTEX was also 10 times faster to install than the previously used conventional FRP concrete. TILTEX provided a total turnkey solution for the client with our engineer design, direct procurement, installation, after sales support and warranty. The project was tested a month after installation with the highest rainfall in 38 years. The product performed perfectly.
