Danby of North America
The Danby Pipe Renovation System is a No Dig process for spirally winding a PVC liner into large diameter pipes. The grouted-in-place liner can be installed in pipes of all materials, shapes, and sizes of 24 inch and larger. Advantages include a minimal reduction in cross-section, an excellent barrier to sulfides, increased structural strength, and in most cases an increase in hydraulic capacity. Surface disruption to traffic and businesses is minimal. Infiltration and exfiltration is greatly reduced or eliminated. Very cost effective.
