The slip lining process is when a new pipe is inserted inside of an existing, failing structure. There are a variety of types of failing structures that can be slip lined. Two important factors to consider when choosing a liner to use in a slip lining application are ensuring that flow rates are equal to or greater than the host pipe, and the ability of the liner to provide structural integrity. Once the annular space is pumped with grout there should be no voids between the new liner, the existing host pipe and the road. A properly installed slip lined culvert should add substantial extended life to the existing structure and allow safe passage over the road.

INFRASTEEL® is manufactured to match the exact shape of the existing structure. The structure has a Manning's coefficient of .012 which improves water flow rates through the culvert. INFRASTEEL® is made from carbon steel with thicknesses from 1/2" to 1" thick, with a minimum yield strength of 36,000 psi. This allows the product to surpass all other products in structural integrity. INFRASTEEL® liners are engineered to exceed the load bearing capacity of new, stand-alone structures.
