Protective Coatings

Smooth operator, smooth service, smooth finish – these are the three main aspects that define InterGroup’s coating services. Our capabilities range from large items to small components, and everything in between. We provide marine maintenance abrasive blasting, intumescent coatings, and blast and paint coating services for buildings, marine vessels and more. Our coating procedure involves pre-application visual checks as well as post-application visual inspections, guaranteeing you to get the finish you want, finished when you want.

PASSIVE FIREPROOFING

Passive fireproofing services are methods of protecting buildings from fire by applying coatings that insulate and resist heat. Intumescent painting is a type of coating that expands when exposed to fire, creating a foam layer that protects the steel structure. Cementitious coatings are another type of coating that are made of cement and water, and provide fire resistance and waterproofing to concrete and masonry surfaces.

FABRIC MAINTENANCE

Fabric maintenance services are methods of preserving and enhancing the integrity and performance of industrial structures and equipment. They may include applying protective coatings, using rope access techniques, conducting non-destructive testing, and performing high pressure water jetting cleaning to remove dirt, scale, and corrosion.

BRIDGES AND STRUCTURES

Bridge and structure protective painting services are methods of repairing corrosion, corrosion protection, preparing steel and applying coatings that protect steel and concrete structures from corrosion and weather. They may involve rigging, containment, surface preparation, and coating application techniques. These services include corrosion assessment which helps to extend the lifespan and appearance of bridges and other structures.
