RIX installed the waterproofing liner, kilometres of strip drains and protection barriers to the tunnel roof and walls throughout the WestConnex M4 project. The design required a 25mm dry shot smoothing layer to be sprayed first followed by 2 x 2mm layers of spray on Tamseal 800 waterproof membrane. Works were completed by hand at height out of elevated work platforms using RIX skilled installers.
