Problem

Examination of recently exposed corrosion in support beams shows serious spalling and delamination.

Solution

SURTREAT® developed a solution to mitigate the corrosion and repair the beams.

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

Scope of Work

• Perform inspection of existing structure
• Tests were performed to determine the existing remaining compressive strength on each quad tee and to the extent of corrosion within the beams
