Concrete Slab Repairs & Flexible Mastic Patching
High-strength load-bearing flexible hot-applied patching for concrete spalls, corner breaks, and wide joints.
Technical Overview & Method Purpose
Rigid concrete roadways and industrial warehouse floors develop localized spalls, corner cracks, and joint raveling under heavy axle loads. Conventional cementitious mortar patches require water mixing, take days to cure, and debond quickly due to thermal coefficient differences. Marathon Sealing applies Crafco Mastic One—a hot-applied, aggregate-filled polymer resin mastic that bonds tenaciously to dry concrete and withstands heavy traffic in 45 minutes.
Engineering Specifications
Executed using genuine Crafco polymer sealants and hot melters with full compliance certification for RTA, MoEI, and municipality tenders.

Spall Delineation & Milling: Breaking away loose, fractured concrete down to solid substrate.
Heat Lance Preparation: Deploys 1000°C dry hot air to eliminate any trace moisture and warm concrete sidewalls.
Mastic Heating & Pouring: Pre-packaged aggregate and binder melted in vertical agitating kettle and poured directly into the cavity.
Trowel Finishing & Skid Dressing: Hand-troweled flush with road grade and broadcast with abrasive aggregate for skid resistance.
