Flowtite GRP Piping

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.
