The repair of random cracks and application of a coating in a secondary containment area was a major concern at this airplane manufacturing plant. Due to the limited shutdown time and low October temperatures most conventional coating systems were ruled out.
VersaFlex rapid curing polyurea sealants and coatings were specified and successfully installed. The random cracks were ground out and filled with VersaFlex SLl 75, which took less than I hour to cure.
Aqualok concrete sealer and primer was then installed to inssure proper bonding.
VersaFlex FSS 45 DC-F polyurea spray, with a 5 second gel time, was applied at a film thickness of 65mils.
The entire project was completed from start to finish in just 4 days, which was half the time it would have taken using a conventional coating system.
Project: Major fracture repair and secondary concrete containment coating
Owner: A major airplane manufacturing company, Wichita, Kansas
Contractor: Doyle, Reed Painting Company
Coating System: VersaFlex SU75 for crack repair and FSS 45DC-F Polyurea
Project Scope: 6,500 S.F.
Installation: October 1995
Clarifier Tank Tops
Project: Clarifier Tank Tops
Owner: S.F. Phosphates Industrial Plant
Contractor: Systems Development Service
Coating System: FSS-50DM Spray Membrane
Project Scope: 41,000 S.F.
Installation: Mid 1995
Corrosion and severe abrasion were two serious problems at this industrial phosphate facility. Maintenance engineers had tried several coating systems over the preceding years in an effort to protect both steel and concrete surfaces.
While various epoxy systems offered some protection they were short lived and took far too long to cure at time of installation.
After in depth research, it was determined that a rapid cure polyurea system might be the solution.
VersaFlex was consulted and a polyurea metal coating system was specified for all surfaces. The approved VersaFlex contractor installed VersaFlex FSS 50DM spray coating to the top of the clarifier tanks to protect steel from dripping 28% phosphoric acid.
In addition, numerous steel support beams were coated for protection against 5% fluosilic acid vapor, which is highly corrosive.
Both shaft and flights on the gypsum filter table needed protection from 10% phosphoric acid as well as the abrasive gypsum in order to extend the auger life from 1 to 3 years.
Vancouver St. Victoria BC

Vancouver St. | Fort St. to McClure St.
Client: City of Victoria - Victoria, BC Canada
Date: November 2014
Summary
In the fall of 2014, Induracoat was awarded a bid to line over 300 meters of Victoria's aging water mains. The project required minimal impact on traffic flows in the area, and priority concern was given to the wide range of mature, and fully established trees within the neighbourhood.
The area was also a heavy mixture of residential dwellings, historical structures, and commercial businesses. Every effort was made to ensure that Induracoat's personnel & equipment were of minimal disruption to the area residents & businesses.
“The dozens of beautiful trees lining both sides of Vancouver Street in Victoria were planted long after the water main installation in 1908. Water main replacement would have likely been lethal to the trees given the water mains current proximity.
The use of our pipe renewal liner provided the city with a trenchless, semi-structural rehabilitation solution without harm to the trees and significantly reduced impact on local traffic flows.”

Client: City of Victoria - Victoria, BC Canada
Date: November 2014
Summary
In 2014 Induracoat continued to provide The City of Victoria with further lining solutions. In this instance, Induracoat lined over 180 meters of 150mm pipe throughout the Sumas Street neighbourhood, including Garbally through Manchester Street.
The weather at this time of year was not a barrier to Induracoat's technology or application process.
"The water main at this location runs directly under the curb where the grass and treed boulevard meets the road. Replacement would have meant weeks of traffic disruption to the commercial and residential neighbours and very likely the loss of several trees.
The area has experienced a higher rate of breaks and the City was seeking a non-disruptive solution to enhance the mains structural integrity. Our trenchless rehabilitation was able to deliver an economical solution."

Date: July 2016
Summary
In 2016, Induracoat again provided lining services for The City of Victoria on Padora Avenue. this line services Victoria City Hall, a local TV station (CTV Vancouver Island) and a centrally located hotel (the Rialto).
The installation of pipe renewal lineracted as a semi-structural liner to ensure that these pipes were sound before investing money in further street surface upgrades.
The City of Victoria was preparing to upgrade the surface streetscape along Pandora St. and was eager to rehabilitate the 1908 water main prior to starting street refurbishment. This extremely busy downtown street is adjacent to Victoria City Hall and centered in Victoria's tourist area.
Full cut replacement would have closed traffic for at least a month, causing significant traffic chaos. Induracoat was able to rehabilitate the water main in three days, while leaving one lane open to traffic."
