 The
U-Liner® process allows us to insert anew polyethylene pipe into a damaged
pipeline through a manhole and reconnect laterals without excavation.
The result is a tight-fitting, structural liner with a design life of at
least 50 years. The U-Liner® process may be used for lines from 6"
to 15" in diameter. Meets ASTM 1533. For more information on U-Liner®,
the U-Liner® installation process and U-Liner® specifications,

 Our
cured-in-place process gives you maximum strength and flow capacity in lines
which have tight bends or transitions in size or shape. National Liner®
pipes may be custom-designed to meet your requirements in strength, wall
thickness, and chemical resistance. Meets ASTM 1216. For more

PIPEBURSTING
 Pipe
bursting is the only trenchless technology which allows for complete size-for-size
or up-size replacement of pipelines. Pipe bursting may be used for
mains or service lines from 4" to 30". Increases of three or four
pipe sizes are common.
SLIPLINING
When achieving maximum flow capacity is not critical, slip lining may be
your most cost-effective solution. Installing polyethylene pipe is
fast and proven. With slip lining, all laterals are connected to saddles
which are fuse-welded to the main line. This assures you of a totally
leak proof system.
