This short video takes a quick look at the geographic location of this project. Which is Kenora, Ontario.

 Project took five months from May to September 2003.

 Project included 100,000 sqr. ft. of steel.

 This was a deck-truss, arch style bridge, badly crevice corroded.

 The structure was disfigured and weakened by 60 years of wear and tear.

 Surface preparation according to SSPC SP12-WJ4-NV2

 Termarust offered a 5 year warranty against coating failure, which included the crevice corrosion and pack rusted connections and joints.

  Standard specification used by the ministry of transportation of Ontario required sandblasting plus a 3-coat zinc-epoxy -eurethane system. The lowest alternative bid was 3.4 million dollars, and beyond the means of the owners of the project.

 Termarust system price comes to 1.2 million dollars and includes a 5 year warranty. Of this amount only 6% is the cost of material.

 Another advantage of this system is that because of ease of application and preparation, bridge remains in use the entire time.

WASHING EQUIPMENTS:

• 3, 5500 psi @5 gal/minute power wash units with 0 degrees rotating tips
• Machine had 24 hp gasoline engine 1.5 gal fuel/hour

POINT APPLICATION EQUIPMENTS:

 TR2100 primer topcoat was applied using an airless system with joints connections, edges, rivet heads, all strip-coated before spray application.

 Termarust system requires no mixing or thinning. Material was pumped directly out of 55 gal. drums.

 Equipment did not need to be flushed at the end of the day. Termarust system will not cure in absence of Oxygen.

WATER COLLECTION AND TREATMENT EQUIPMENTS:

 The water collection system was very simple. Water proofed platform collected the water allowing it to flow down to sumps at lower point in containments.

 Containment was very light due to the fact that no excessive loading was used.

 From the sump water was pumped into a tote tank where solids settled in and water was skimmed off the top and pumped through filters to remove suspended particulates.

 Water went to recycled water holding tank. Recycled water was mixed with fresh water from fresh water make up tank and pressurized and fed back into the wash unit.

 Needle gun preparation was used to fracture tightly adhered black oxide so it could be easily removed by 5500 psi water.

 Chlor-rid injection: At the final rinse chlor-rid solve inject remover was injected at a ratio of 1/100 using Dosmatic pump.
This was done to remove any residual salt before the operation.

SURFACE PREPARATION:

 Surface was prepared by using the 5500 psi water at 5 gal/minute. All areas received this treatment especially the crevice corroded and pack rusted joints and connections.

INSPECTOIN OF SURFACE PREPARATION:

 300 adhesion tests of existing pointes were done using a DeFelsko positest to a ASTM -D 4520 standard, with minimum value of 300 psi.

SALT TEST:

 NV2 standardizing Chlor-test sleeve method.

COAT APPLICATION:

 All crevice corroded joints and connections were treated with TR2200 penetrant sealer.

 After application excess penetrant is brushed out.

INSPECTION OF PENETRANT SEALER APPLICATION:

 Visual inspection

APPLICATION OF TR2100 primer topcoat

 Strip coat of TR2100 is applied to all joints and connections, edges and rivet heads to achieve a uniform coverage.

 Areas are spot primed with 7-9 mills DFT of TR2100 primer topcoat.

 Uniform coat of TR2100 by airless spray of 7-9 mills DFT cover the entire bridge.

FINISHING INSPECTION OF FINISHED COATING

 This is done using a digital probe type, thickness gauge and if the coating has not completely set up at 10 mills shim is used between the probe and film to ensure accurate reading.
