Testing and inspection

-Low pressure testing of complete sewer lines from 2" to 36" up to 500' in length.

-Low pressure joint testing of large diameter Sewer/ Storm pipe 36" to 144" inside diameter

_Hydro-static testing of pipe lines

-Mandrel testing  sewer/ Storm pipe 4"

 to 36" ( Custom sizes available )

- Line leak isolation/ Static Leak Isolation is performed should a drain 

system fail the general test

-Electronic locating and mapping of sewer/ Storm systems

-Continuity testing tracer wires and line locate.

- Negative pressure testing ( vacuum )of concrete, fiberglass and plastic manhole structures. 

-Hydrostatic testing of concrete manholes 

Video inspection is just as it sounds. We send a crawler and camera down sewer and storm lines to look for proper instillation and or defects to be repaired. Camera can inspect lines from 2" to 144" in diameter.

Defects we look for 

-low spots holding water

-exposed gaskets or leaking water

-pulled connections or joints

- laterals/ connections in correct location 

-broken pipe

-debris in pipe/ We clean the lines if necessary

-deflection

-Roots entering the line

-proper grade

We pour channeled bases in sewer/ storm manholes in 24" to 144" inside diameter . All channels are hand formed unless specified by a city or state agency. All materials meet or exceed ASTM standard for strength. 

-channels are poured to 1/2 , 3/4 or full diameter of pipe 

-includes filling in around pipe connection 

-by-pass available for live or active sewer/ storm lines

-specific mix designs available at customers request

* GROUTING/ SEALING

-For active leaks and vacuum testing
