Flexogrid Overlay System Flexogrid is a polymer concrete overlay system for use on bridge decks (5). It uses an aggregate and two-part epoxy binder to create a thin bonded overlay and is developed and marketed as a lightweight, anti-skid, durable wearing surface. Flexogrid consists of the Mark-371 aggregate and Mark-163 epoxy.

Cement-based overlays are sometimes used, but most systems today are polymer-based overlay residents mixed with sand, cement, and additives for improved appearance and performance. Polymer overlays are popular because they adhere well to existing concrete slabs and resist damage from UV exposure, extreme temperatures, abrasion, chemicals, and salt.

T-18 Methyl Methacrylate Thin Slurry Overlay Transpo T-18 methyl methacrylate (MMA) polymer concrete is a fast curing thin overlay. It is a pre-packaged system ideal for concrete and steel bridge decks and other concrete structures.
This is where the polymer comes into play, giving strength to a thin cement-based product — in essence, replacing the larger stone. There are two common polymer types used by most decorative overlay manufacturers: ethylene vinyl acetate (EVA) and acrylic.
The polymer overlay will not only protect the bridge but it will also periodically restore the skid resistance, appearance and riding quality of the deck surface. A hybrid preventive maintenance approach is recommended for bridges with typical service life of 50 years.
Cement-Based Polymer Overlays are applied in layers from ¼ inch to several inches thick. Polymer Overlays are applied to any concrete surface located inside or outside. It’s usually a lower cost than removal and replacement of flooring.

Although cement-based overlays have been around for decades, many of today's systems blend polymer resins with cement, sand, and other additives to improve performance, wear resistance, and aesthetic qualities.
The polymer acts as a water reducer, ultimately leading to a stronger mortar with fewer voids, or weak spots. 3. Improved adhesion. Polymer modifiers act as an adhesive to enable the modified mortar overlay to stick to a variety of surfaces such as concrete, masonry, brick, wood, rigid polystyrene and polyurethane foam, glass, and metals.
