  Beam Test  
     
 

Above, you can see a 3-edge bearing test showing the relative strength of Linabond Structural Polymer with concrete reinforced with an 11,000 psi grout. The concrete and grout typically fail at 700 pounds of force. The Structural Polymer sample, as you can see, can be loaded to more than 10 TIMES that amount without catastrophic failure, and you can see the material handling over 7 THOUSAND pounds of load without failure. The Linabond Structural Polymer adds tremendous strength very economically without adding any significant weight to the structure, since 75% of the volume of the Structural Polymer is gas. It is an extremely efficient use of materials, both structurally and economically.

  • Eliminates wastewater concrete corrosion in municipal wastewater treatment and collection infrastructure
  • Designed for both new construction and rehabilitation of existing wastewater structures

    Wastewater corrosion protection is similar in many ways to "protection" that is common in both Law Enforcement and Disease Control. Law enforcement officers do not go into a "hazardous environment" without a real "flack jacket". They do not apply a coating to their bodies and hope that it will protect them from harm. They typically wear a laminar composite with... backup protection. It keeps them alive.

    Doctors who work on communicable diseases do not rely on a "coating" on their bodies to prevent the contraction of a fatal disease. They use multiple "layers" of protection.

    Wastewater corrosion is most commonly the result of a "biological infection" in a "hazardous environment". If you think about Police and Doctors, you will probably take the time to understand what Co-Liners™ do and how they work.


Hydrogen Sulfide Concrete Corrosion Mechanism:

Wastewater corrosion protection is a major problem for municipalities worldwide. Every year, hundreds of millions of dollars are lost to wastewater concrete corrosion and the failure of H2S corrosion protection on a very wide range of structures, including pump stations, wet wells, plant influent structures, sedimentation tanks and many varieties of conveyance structures within the conveyance and treatment systems of every large city in the world. Most wastewater corrosion protection has become ineffective since most large cities began enclosing their collection and treatment structures in the 1970's. Although the problem is essentially a biological problem, the main failings of the materials used for wastewater corrosion protection can be reduced to 2 main problems.

Wastewater coating systems typically do not fail because of their chemical makeup, but rather due to the environmental conditions which are inherent in working on wastewater structures in an H2S corrosion protection application. Those conditions are constantly changing, minute by minute, as the substrate "breathes" vapor and corrosives through the liquid applied coating. The coating itself may be very well-designed, but the coating design cannot change the environment in which it must be applied. Usually, the contractor has a great deal of difficulty controlling this environment as well. The resulting wastewater concrete corrosion develops behind the wastewater coating system due to permeability that is inherent in the application method, rather than contractor error or faulty coating materials. Liquid applied materials rank very poorly as H2S corrosion protection due primarily to this problem.

Wastewater lining systems typically fail due to lateral migration of corrosive Hydrogen Sulfide and thiobacillus, rather than permeability. Colonization of the thiobacillus actually causes wastewater concrete corrosion behind the liner where the fastening mechanism is located. You will find a great deal of information on successive pages regarding these problems and how you can defeat them on your own projects involving wastewater corrosion protection.
