SIPP Culvert Rehabilitation

Rehabilitation is accomplished using a spray applied combination of products:

• Nukote PP300 is a structural elastomeric hybrid used to achieve the structural requirements to meet VDOT Load Ratings. This base layer is applied directly to the host pipe creating a new conduit and replacing the host pipe. (TDS | SDS)
• Nukote STM is a tough elastomeric hybrid that provides good impact, abrasion and chemical resistance. The STM product will be applied on the internal surface to provide longer wear and impact resistance. (TDS | SDS)

Both materials will be applied robotically on round culverts and manually on arched culverts. Application is monolithic with no layering.

Complete application comes without negative change to the hydraulics. The loss to the radius is minimal, often under 1". The Manning's n Value is 0.0095 and Average C Coefficient is 149.

This liner solution is especially good for large culverts due to the lighter application thickness.
All culvert types, 36" and larger (haven't found one too big yet)
