T-18 MMA Thin Overlay System

T-18 methyl methacrylate (MMA) polymer concrete is a fast curing thin slurry overlay. It is a pre-packaged system ideal for concrete and steel bridge decks and other concrete structures. T-18 is comprised of a blended aggregate filler that forms a slurry when mixed with the polymer resin and broadcast with a coarse-wearing aggregate for vehicular/pedestrian traffic.

Features and Advantages

  • Fast Cure (Approximately One Hour)
  • Waterproof
  • Wide Application Temperature Range (14°- 90°F)
  • Easy Application
  • Skid Resistant
  • High Early Bond Strength
  • High Elasticity
  • UV Light Resistant
  • Chemical Resistant
  • Steel and Concrete Compatible

The short cure time of the system assures a minimum downtime and a quick restoration of service. The broadcast aggregate provides a highly durable, skid resistant surface that can be used for vehicular and pedestrian applications.


T-18 is applied using a single application slurry method. It is easy to handle and does not require any specialized installation equipment. It can be used as a wearing surface on various types of structures:

  • Concrete Bridge Decks
  • Steel Orthotropic Bridge Decks
  • Parking Garages
  • Ramps and Sidewalks
