Ocean City Longport Bridge

Problem

The Ocean City Longport Bridge in New Jersey had visual micro-cracking in the bridge deck concrete. This micro-cracking occurred the entire length even though the bridge had only been in service for less than a year.

Solution

SURTREAT® products were spec’d and used to repair the micro-cracked surface.

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

• The concrete surface was pressure washer cleaned to remove chlorides, dirt, and grime.

• Applied SURTREAT® spray to the deck and brushed in with a commercial sweeper.

• Applied a migratory chemical formulation specially designed to reduce porosity, increase surface hardness, and resist chemical attack.

• Applied SURTREAT® to the cracks in the concrete using hand held sprayers.
