Warren Environmental Systems
Team PPF Announces Partnership with Warren Environmental, Inc. to sell & apply industry leading, high build, structural epoxy.
Plastic Pipe Fabrication (a division of EJP) is
proud to be the licensed applicator of Warren
Environmental Systems 100% Solids Epoxy Coating.
This unique product and application process has
the ability to produce a ceramic-like, plastic finish
in damp environments that can resist attacks by
hydrogen sulfide and other aggressive chemicals.
Structures can be completely rehabilitated with
minimal or no out-of-service time. Warren
Environmental System (WES) is environmentally
friendly and safe to apply in confined spaces.
WES epoxy is used by a growing number of
municipalities to protect sewer manholes from
hydrogen sulfide attack as well as infiltration
from ground water. Industrial plants are finding
many uses for WES epoxy in their underground
systems including containment structures holding
high temperature materials and chemicals. Sewer
Treatment Plants as well as Water Treatment
Facilities are finding WES very helpful in restoring
concrete or steel tanks. WES has NSF 61 approval.
The Warren structural epoxy manhole liner system delivers a stand-alone, self-supporting structure when applied at 250 mils to badly deteriorated structures. At 100 mils the system will protect new concrete from H2S attack and seal out infiltration, enhance the flow, and reduce buildup in the structure. The hard, ceramic-like plastic shell has proven to reduce odors emanating from manholes and pump stations. With over 10,000 structures in place, the Warren system has passed the test of time.
The town of Bethlehem, New York was informed by their
consultants their potable water clarifier was near the point of
total failure. The cathodic protection system had failed, allowing
corrosion to overcome the 50 year-old metal structure. The
corrosion had penetrated 3/4 of the way through the sidewall of
the vessel. The township had 3 options: 1) Build a new tank. 2)
Patch weld 80% of the clarifier. 3) Apply the Warren structural
epoxy at 1/4 thickness. At the two-year inspection, the plant
supervisor said Bethlehem’s gamble on Warren epoxy had paid
off when the inspection revealed the structural epoxy to be in
“like new” condition, with no sign of new corrosion.
The Boston Water and Sewer Commission lined a badly deteriorated section of 8 foot brick storm drain. The test section had a crack 30 feet long, 8 inches wide through 4 layers of brick and severe scarring of the tunnel walls. The test section was repaired with Warren epoxy mastic M-301, and top-coated with 1/4 inch of S-301 during one eight hour window. Boston Water and Sewer has specified the Warren system on some of their most challenging crack repair and infiltration projects.
Surface prep, testing, and inspection are the three most common causes of success or failure on any project. Surface prep must be a multi-step process, with a written detailed specification of what is acceptable for surface prep prior to application of epoxy materials. Field inspection is a demanding process and field inspectors should only be assigned the duties of inspection. Testing should be a combination of physical test in laboratories, measurements of wet materials during application, and post application testing such as adhesion test, spark test, vacuum test, etc.
