The Advantages of Seawall Concrete Preservation
Concrete is chemically formed through a process known as hydration/curing. Concrete deteriorates chemically under the influence of soil, water, and air-born contaminants, weathering action, and corrosion of the embedded steel reinforcement. Seawall Repair Network® offers a complete solution to prevent, restore, and protect steel reinforced concrete by modifying its chemical and physical properties. By restoring the properties of your seawall’s existing concrete (as opposed to replacing it) Seawall Repair Network®‘s preservation system provides cost and time savings, while limiting disturbance to surrounding structures and property. These materials are environmentally safe and are intended for use in marine environments.
SW-Prevent: Seawall Corrosion Inhibitor
SW-Prevent penetrates concrete and inhibits corrosion of steel inside the wall. This material penetrates as vapor to deposit on steel components such as rebar or mesh inside. Corrosion is prevented by creating an insulating layer on the surface of the steel.
SW-Power: Seawall Strength Builder
SW-Power is a penetrating material primarily designed to reduce concrete porosity, increase strength and render concrete surfaces resistant to air or water-born chemical damage. SW-Power provides additional protection by supporting ideal pH levels in the concrete to prevent rebar corrosion.
SW-Protect: Seawall Surface Protector
SW-Protect inhibits water penetration in concrete. Surfaces treated with SW-Protect will repel water, dirt, and grime – helping keep your concrete clean and free of mold, stains and discoloration. SW-Protect is not susceptible to UV degradation, providing a durable long-term protection to all porous surfaces.
“The SURTREAT system, based on measurements of corrosion rate and moisture penetration is effectively protecting the rebar from corrosion. To date, an average reduction in the corrosion rate by 79-80% has been realized.”
NAVFAC (NAVAL FACILITIES ENGINEERING COMMAND)
“The data obtained during testing on this project show quantitatively that the corrosion inhibitor application significantly reduced the corrosion rate of the rebar on the tested structures. It can be projected that the service life of these structures has been extended by more than 10 years.”
