Patuxent River Naval Air Station

Location: St. Mary’s County, Maryland

Structure: Four Concrete Pad Program

Problem

As a result of constant aircraft traffic random fine cracks have developed on the surface of the concrete. If left untreated, these cracks will enlarge. These cracks then lead to the formation of concrete fragments, foreign object debris (FOD), which can become airborne and have the potential of being sucked into jet engines causing damage.

Solution

SURTREAT® is a proprietary, water based, environmentally friendly solution of activators and migratory aids that inhibits rebar corrosion, increases strength and reduces porosity in reinforced concrete.

SURTREAT® Solutions

• Inhibits salt, water, air and contaminates from penetrating the concrete and forms a better seal in the pores and micro cracks

• Controls pH and maintains the high alkalinity in the  concrete and is highly acid resistant

• Migrates to the rebar in liquid and ionic phase and reacts to form a very stable passivating film – more stable than in new concrete

• Converts rust to a stable, inert compound – and increases compressive, flexural, and tensile strength. Also increases hardness and abrasion resistance
