Flow-Crete™ is a first-in-class composite pipe designed to meet the strict requirements of jacking and microtunneling installations for both pressure water and sewer applications. It combines the compressive strength of reinforced concrete with the corrosion resistance and pressure capabilities of the Flowtite™ fiberglass pipe.


Download the Flow-Crete PDFThis composite pipe incorporates an outer loadbearing wall of reinforced concrete and an inner Flowtite™ fiberglass liner pipe. The wall thickness of the RCP is designed to accommodate the jacking loads and distances under consideration and the dimensions of the equipment used in the jacking process. The Flowtite™ liner is built to withstand the internal pressure of aggressive sanitary sewers and other corrosive liquids. Flow-Crete™ is supplied with injection ports and pressure compression rings to facilitate jacking operations when required.

Flow-Crete™ is manufactured under the strictest quality controls.

  • Computer-controlled batching maintains consistency and provides uniform jacking loads for each pipe.
  • Higher compressive strength mixes can be formulated to increase the allowable jacking forces, which provides the ability for longer drives.
  • The Flowtite™ pressure joint system is cast inside the Flow-Crete™ creating a pressure-rated, microtunneling pipe.
  • Flow-Crete™ is designed and manufactured to each customer specification and project
