Tarmac Toproc Ready-Mix Concrete - Albert Bridge, Glasgow

This project was an ideal demonstration of the unique properties of Toproc UW. The concrete was required to be very fluid to enable it to be placed, but at the same time it had to be very resistant to washout whilst fresh. The concrete was pumped directly underwater to repair the supports in the river for the road bridge. Once hardened, the concrete was also required to resist the scouring effects of the river, particularly during flooding.

Technologies

The unique rheological properties of Toproc UW, being non-bleeding and thixotropic, actually enable divers to trowel the surface up under water. In clearer water, the negligible washout also improves visibility for divers. This clearly demonstrates why Toproc UW is regularly specified for use even in the clearest of mountain streams by numerous bodies including the National Rivers Authority, as it has so little of an effect on the fish.
