V-ROD Fiberglass Rebar | Transportation Solutions & Tunnels

V-ROD Fiberglass Rebar are one of GAMKA’s best non-metallic reinforcements solutions for our customers, especially in the field of transportation. Bridges, bridge decks, and restraint systems are all serviced by our V-ROD Fiberglass Rebar, as are diaphragm walls of tunnels.

As a lead distributor for United States construction of civil engineering works, GAMKA helps our customers build concrete bridges reinforced with V-ROD composite rebars for both repairs and new constructions.

V-ROD Composite Rebar For Restraint Systems, Bridge Decks, and Bridges

When exposed to the effects of de-icing salts, the reinforcement of structures such as bridges, restraint systems, and bridge decks can often become their greatest weakness. This results in expensive repairs and replacements of these structures that are far from reaching their expected service life.

With GAMKA’s V-ROD product, however, user safety and infrastructure durability are the two key factors that make V-ROD the logical choice for designers, owners, and public–private partnerships.

V-ROD Composite Rebar in Tunnels and Diaphragm Walls

These days, tunnels are constructed with a variety of techniques, such as the more traditional bored-tunnel method or the cut-and-cover (open-pit) method. Using shields and tunnel boring machines (TBMs) is more common and requires an extraction shaft and reinforced concrete launch box.

While TBMs are well-suited for boring through concrete, they are not necessarily adapted to bore through a steel-reinforced concrete structure. This is due to the resilience of the steel.

Thus, steel reinforcement can substantially delay or disrupt the process of rotary cutters because of its ductility, absorbing the cutter’s energy and deforming instead of allowing them to fracture the concrete as they’re supposed to.

However, GAMKA’s V-ROD composite rebars can elude this problem, as they are usually located in the area where TBMs go through the reinforced concrete wall, which is known as the diaphragm walls (Soft Eye). This is because the elastic-to-rupture behavior of V-ROD allows TBMs to bore through the reinforced concrete structure without presenting any more resistance than what would be experienced when boring through rock or unreinforced concrete.

The ultimate result of GAMKA V-ROD composite rebar solution is a reinforcement pattern that exhibits minor differences when compared to the steel version and a greatly improved work schedule, as the demolition step with steel reinforcement is no longer required.

In other words, V-ROD will save you money and time in the long run. Far less costly than Stainless Stee Rebar or Epoxy Coated Rebar and requires less concrete cover than using plain rebar.
