The steel culverts under a privately owned railway line were failing
due to corrosion.
Flowtite GRP with its inherent corrosion resistance and high inte-
gral stiffness was a quick and lightweight solution to the problem
and provides a service life of 100 years +.
The GRP lengths were slip lined into the existing steel culvert and
grouted structurally into place providing a total stiffness (ability to
handle traffic loading) above that required in the original install.
An unique feature of Flowtite GRP, was during transportation to
site, the various sizes were ‘nested’ inside each other thereby
maximising freight and reducing transportation costs.
