Channel linings are an essential part of any causeway development and need serious consideration and planning as they’re being implemented. Everything from channel slope to flow depth must be measured to assess the right lining design and appropriate material application and, up until cable concrete innovations, the accepted material for standard channel lining could have been any number of materials including soil, vegetation, turf reinforced mats, hard linings or rolled erosion control products.
Today, cable concrete is getting the nod for many modern channel lining projects and is even being used to retrofit older channel linings that have since become compromised over time. Why? Though traditional materials have proven to be acceptable when it comes to protecting channels from erosion and other degradations, cable concrete presents qualities that far outstrip other material options. Simply put, cable concrete stands up to more abuse over time, presents fewer complications when it place and represents a lasting solution that doesn’t require costly upkeep in the future.
In order to truly understand why cable concrete is such a superior choice over other material options, it helps to see where these other options fall short and how cable concrete triumphs in the wake of these failures:
- Unprotected soil: Unprotected soil is easily eroded or degraded in the wake of excess water and can quickly become permanently damaged in the wake of flooding, resulting in an immediate need for renovating and reshaping.
- Vegetation: Like unprotected soil, vegetation provides very little erosion resistance in the wake of flooding or heavy rushing water. The resistance it does provide is quickly offset by the fact that vegetation can become susceptible to damage over time via natural ecosystem factors.
- Turf reinforced mats: Formally the best option in channel lining materials because of its ability to cope with abuse and high velocity flow conditions, turf reinforced mats have become second to cable concrete mats because of the longer lasting tendencies of a concrete product.
- Hard linings: Hard linings, such as natural rock and gravel layering, are a solid option for channel linings, but lack the immobility of cable concrete. In a high velocity flood situation, small rocks can be swept away, while larger stones are subject to intense weathering.
- Rolled erosion control products: The chief concern of rolled erosion control products is the potential environmental impact that they can have—being made of fabricated materials, integration into the ecosystem is not always seamless, leading to future complications.
Cable concrete solves the majority of these issues to represent a lasting and assuring channel lining solution. Thanks to its easy incorporation, tremendously low upkeep, practicality and various other triumphs over traditional materials, cable concrete is a standby that engineers and contractors can put their faith in when it comes to channel linings. Cable concrete goes above and beyond, providing higher maximum permissible velocity thresholds, tractive force and various design capabilities. In short, for today’s channel lining projects, cable concrete is a clear and decisive investment for the future.
