When it comes to salt mists, one of the most exposed concrete structures are definitely retaining walls, whether they be placed along roadways and splashed by passing vehicles or situated in a coastal environment.
The durability of these structures is often questioned and it is not unusual to see them reinforced with so-called corrosion resistant steel rebar. Among the other techniques used to extend the service life of these walls we can list the use of sacrificial anodes or cathodic protections as well as the addition of a corrosion inhibitor to the concrete mix or the application of a surface sealant.
With the product V•ROD of Pultrall...
Because of the above, these concrete elements represent a particularly well suited application for the V•ROD technology, which will not be influenced by the intrusion of chloride ions in the concrete matrix and therefore ensure a service life that will often times exceed the general and initial expectations. In addition, the V•ROD composite material concrete reinforcing rod being much lighter than steel, the installation work will be facilitated, no matter if it is done on-site or in a precast plant. In brief, durable structures at a more than reasonable cost are now more than ever possible.

about V•ROD rebar.
V•ROD rebar does not rust, even in the harshest environments. It does not react to salt, chemical products or the alkalinity present in concrete.
V•ROD rebar does not create a thermal bridge within structures.
She is almost 4 times lighter than steel rebar. It is much easier to handle and, in most cases, one truck load will be sufficient to carry the rebar required on an entire project.
V•ROD rebar offers a level of thermal expansion comparable to concrete due to its 80% silica content.
V•ROD rebar does not contain any metal; it will not cause any interference in contact with strong magnetic fields or when operating sensitive electronic instruments.
V•ROD rebar produced by pultrusion offers a tensile strength that can reach more than five times that of steel.
V•ROD rebar can be delivered at the right time and in the exact quantity needed at the site. Various specifications such as the length of straight bars as well as angles and led lengths of special bent sections are prepared in the plant.
