The world’s largest company in the field of sea water desalination (SWCC) consulted LINE-X to find a solution to protect the company’s brine drain channels. Each desalination plant consists of several production units. Each unit has a drain channel that allows the return of brine to the sea water. The brine has a very high salt concentration and is delivered at a high temperature 50-80 C to the sea through concrete channels.Over time the concrete channels suffered great structural damage. Salt water penetrated through the concrete to the structural steel leading to corrosion and failure. The channel walls were critically damaged and falling apart in several areas.
Due to urban sprawl more and more communities and engineers are taking additional steps to protect and extend the service life of new and existing wastewater structures. A municipality in one such area controls a pumping station that has been degrading slowly over time. The walls of these stations are particularly susceptible to the corrosive environment and will easily deteriorate without protection. As infiltration and the effect of corrosive gases are the two primary causes of deterioration in a collection system, the addition of a corrosion barrier to a new structure will not only ensure a longer service life to the system, it will make the rough concrete surface easier to clean.
Concrete is extremely susceptible to water damage. Because concrete is porous, water can easily permeate a building’s foundation causing damage. The best way to prevent water from penetrating concrete is to seal any pores and cracks with a waterproof membrane on the outside of the foundation.
Concrete, with its porosity and high-pH, is susceptible to many forms of decay. Continuing maintenance on concrete structures is a very costly necessity; corroding concrete lose sits strength and structural integrity and often leads to corrosion of the rebar within.
