When it comes to pipeline protection, the choice of material can make or break the performance of your project. On one side, we have PVC rock shields – the outdated and rigid option that’s been used for years. On the other, there’s Grid-GuardHD PLUS, a modern, reliable solution built to withstand the toughest conditions. Let’s compare these two and see which one truly stands up to the demands of today’s pipeline protection needs.
Fighting out of the yellow corner…
the long-time contender, PVC Rockshield! With its rigid plastic construction and outdated design, this heavyweight has been around the block, but age isn’t always an advantage. Known for its inconsistent structure and tendency to get brittle in the cold, it’s been the go-to for years—but is it still the best?
And in the black corner…
the challenger, Grid-GuardHD PLUS! A high-performance, next-generation rockshield built with a three-dimensional mesh and a geotextile backing for superior protection. Lightweight, flexible, and engineered for extreme conditions, this fighter is ready to take on anything the pipeline throws its way.
The battle is set, the stakes are high—which rockshield will come out on top?
Let’s get ready to rumble!
PVC Rockshield
The production of PVC (polyvinyl chloride) involves the release of harmful toxins, contributing to pollution. Once PVC is buried underground, the phthalates used as plasticizers in the material tend to leach into the soil. These chemical additives can disrupt soil ecosystems, harming plant life, soil animals, and microbial communities. Over time, PVC breaks down into microplastics, which continue to leach into the soil, further polluting the environment and negatively impacting soil health. (source: ScienceDirect).
Grid-GuardHD PLUS
On the other hand, HDPE (high-density polyethylene), the material used in Grid-GuardHD PLUS has a cleaner and safer environmental profile. HDPE is commonly used in the production of landfill liners and stormwater management systems, as it effectively prevents harmful chemicals from leaching into the environment (source: Ninge Plastics). This makes HDPE a great choice for pipeline protection, as it ensures that no toxic substances are introduced into the soil during the pipeline’s operation, which is critical for long-term ecosystem health. Additionally, HDPE does not contain harmful additives like phthalates, making it a much safer option for the surrounding environment.
WINNER: Grid-GuardHD PLUS (HDPE), for its cleaner production, lack of toxic additives, and its ability to prevent contamination, making it the eco-friendly choice for pipeline protection.
PVC Rockshield:
In the battle for pipeline protection, cold weather performance is crucial. While PVC rock shields have served their purpose over the years, they come with a critical flaw when the temperature drops. At -10°C, the rigid PVC material not only becomes brittle but also loses its flexibility, making it very difficult for installation crews to properly wrap it around the pipe. The stiffness increases the risk of cracking, damaging both the shield and your pipeline in the process.
Grid-GuardHD PLUS
In contrast, GridGuard HD Plus, made from extruded polyethylene, was designed with cold weather in mind. It stays flexible and impact-resistant even at temperatures as low as -40°C. Unlike PVC, it remains pliable and easy to install, even in the harshest of winter environments, ensuring a quick, hassle-free application when you need it most. No cracked material, no complications—just efficient pipeline protection.
WINNER: Round 2 Goes to Grid-GuardHD Plus! When the cold hits, PVC cracks—GridGuard keeps its cool!
PVC Rockshield
Features a random design with varying hole sizes. While it offers basic protection, the inconsistent hole pattern can create weak points where backfill could potentially infiltrate. This inconsistency in design doesn’t provide uniform coverage or impact protection, and over time, the gaps in the material could lead to damage to the pipeline. As backfill shifts and settles, these weaknesses could become even more problematic, potentially causing abrasion or punctures to the pipeline coating.
Grid-GuardHD PLUS
Grid-GuardHD PLUS, on the other hand, utilizes a three-dimensional mesh pattern, creating a consistent, uniform layer of protection. This design offers reliable backfill protection, ensuring no weak points where damage could occur. In addition, Grid-GuardHD PLUS comes with an extra layer of protection: a geotextile backing. This backing provides 30% more impact protection, which helps prevent backfill material from damaging the pipeline. The geotextile is completely permeable, allowing water to flow through without holding any moisture, ensuring that the pipe remains dry and protected against corrosion. This permeability is essential in preventing water retention, which could otherwise compromise the integrity of the pipeline.
WINNER: Grid-GuardHD Plus wins this round with its uniform coverage and added geotextile backing, providing superior protection against backfill damage.
PVC Rockshield
Features a random design with uneven hole sizes, which can lead to difficulties during installation. Its heavier weight (0.825 lbs per square foot) requires more manpower for setup, and the irregular structure can cause it to catch on uneven areas or bunch up in cradles, slowing down the entire process. The narrower spacing between tape wraps further complicates installation, making it a less efficient option on the job site.
Grid-GuardHD PLUS
Grid-Guard HD PLUS is designed with a three-dimensional mesh pattern that ensures consistent and uniform coverage during installation. Its stable structure eliminates the risk of bunching or catching on uneven areas, making it easier to handle during setup. Additionally, Grid-GuardHD PLUS’s lightweight composition (0.45 lbs per square foot) reduces the need for multiple workers and makes handling much more manageable. With up to 18 inches of spacing between tape wraps, the installation process becomes faster and more efficient, allowing for fewer hands on deck.
WINNER: Grid-GuardHD Plus takes the win again with its lightweight design and smooth, efficient installation process.
WINNER BY TKO: GRID-GUARDHD PLUS
After four intense rounds, the champion is clear—Grid-GuardHD PLUS takes the belt with superior environmental impact, unbeatable cold-weather flexibility, unmatched backfill protection, and effortless installation. While PVC Rockshield put up a fight, it couldn’t go the distance against Grid-GuardHD PLUS’s next-generation design and all-around performance.
