The rehabilitation of an aging infrastructure has become the focus of many older agencies. Triad Engineering has become very involved in this process. We have installed thousands of feet of different sliplining pipe products of up to 54" in both straight runs and curves. For this process, Triad has done its own cleaning, installation and grouting. We have operated in live sewage as well as bypass pumped conditions.

Rehabilitation also requires the management of connections into the new pipe system. Triad has used various creative methods to effectively connect sewers to the slipline pipe.

Shotcrete lining is also being used as a means of rehabilitation for old brick sewers.Triad is experienced with shotcrete and has performed shotcrete rehabilitation in old brick arches and sewers. We also are a certified installer of the Sekisui SPR spirally wound PVC liner. Both of these methods are used in older, non round or oval shaped sewers.
