If you’ve spent any time on construction sites, highway expansions, or even reforestation projects near urban areas, you’ve probably noticed artificial slopes—engineered earthen embankments, rock cuts, or graded terrain designed for stability, drainage, or land use. As a slope netting supplier, one of the most common questions I get from civil engineers, contractors, and environmental project managers is simple: Can slope netting actually be used on these man-made slopes? For years, there was a lot of confusion on this topic—some thought it was only for natural rock faces, others feared it would disrupt drainage or cause more harm than good. But after 12 years of working alongside teams on over 700 slope stabilization projects, I’m here to break down the truth, share what we’ve learned, and explain how slope netting is not only viable for artificial slopes—it’s often one of the most reliable, cost-effective solutions out there. Slope Netting
First, let’s clarify what we mean by “artificial slopes.” They aren’t just random piles of dirt—they’re engineered with specific specs: a predetermined angle (usually between 1:1.5 and 1:2.5, depending on soil type), compacted to a set density, and often layered with geotextiles or drainage materials during construction. These slopes are built to support land development, roadways, utility lines, or recreation spaces, but they’re far from impervious to failure. The biggest threats to artificial slopes aren’t large rockfalls like you’d see on a mountain—they’re gradual, cumulative issues: surface erosion from rainwater runoff, wind-driven soil loss, freeze-thaw cycles that crack compacted earth, and even small, incremental sloughing of soil that can turn into bigger, more costly failures if left unaddressed.
A few years back, I sat in on a pre-construction meeting for a 1.2-mile highway widening project in central Pennsylvania. The state DOT’s geotech team had initially planned to use only hydroseeding and mulch for the 30-foot-tall artificial embankments, a plan that would have cut material costs by nearly $200,000. But their lead engineer, a guy named Tom who’d been in the industry for 22 years, raised a red flag: Pennsylvania gets 45 inches of rain a year, and those steep compacted slopes would experience concentrated runoff at the base of the grade within three years—erosion would carve ruts, weaken the embankment, and even threaten adjacent drainage culverts. We presented our lightweight, flexible polyethylene slope netting designed specifically for soil embankments, and after a small test plot on a 500-foot section, they switched the full project. That plot still looks good six years later—no major erosion, no need for re-seeding, and the netting has held up through two heavy winter freeze-thaw cycles.
But here’s the thing: not all slope netting works on artificial slopes, and that’s where a lot of people get tripped up. For natural rock slopes, you need heavy-gauge wire netting with anchor bolts drilled deep into bedrock to catch falling boulders. Artificial slopes, by contrast, are made of compacted soil, sand, or fill material—so over-engineering with heavy netting is a waste of money, and can even cause problems. We’ve seen contractors use rockfall netting on soil slopes before, and the result was two-fold: the heavy netting required more aggressive anchoring that disrupted the compacted soil layers, and its tight mesh prevented air and water from reaching the hydroseeded grass or plants underneath, leading to patchy growth that left gaps in protection.
The right slope netting for artificial slopes has three key characteristics. First, it’s lightweight, usually made of high-density polyethylene (HDPE) or low-carbon steel wire coated in UV-stabilized polyethylene. The coating is non-negotiable—artificial slopes are often in exposed areas, like alongside highways or on the edges of residential developments, so the netting needs to resist fading, cracking, and degradation from sun exposure for 10 to 15 years, minimum. Second, it has a uniform mesh size, usually between 5cm and 10cm for soil embankments. Small enough to hold individual soil particles in place, but large enough to allow water and air to pass through—this is critical for drainage, which is the #1 cause of artificial slope failure. Third, it’s flexible enough to conform to the slope’s grade without stretching. Artificial slopes aren’t perfectly smooth—they have small irregularities from compaction, so a rigid net will create gaps that let soil escape.
Another common misconception is that slope netting blocks vegetation growth. I get this a lot from environmental project managers who are focused on restoring native plant species after construction. But when we pair slope netting with a proper seeding mix (grasses, wildflowers, or native shrubs, depending on the project), the netting actually helps vegetation establish faster. By holding soil particles in place during the first six months after planting—when roots are still shallow and can’t fully hold the soil—we eliminate the risk of seed washout during heavy rains. On a reforestation project we worked on in western North Carolina, the contractor was planting native pine saplings on a 40-foot artificial slope that had been graded for a new parking lot. They used our mesh netting staked around each sapling’s base, and within a year, the sapling survival rate was 92%—compared to 68% for the control section without netting. The netting also suppressed weed growth around the saplings, reducing the need for herbicides, which is a win for both the project budget and local ecosystems.
Of course, slope netting isn’t a one-size-fits-all solution for artificial slopes. There are cases where it’s not the best option, and that’s part of why we work closely with project teams to assess each site before making recommendations. For example, if an artificial slope is going to be used for heavy foot traffic—like a trail slope in a park—we’ll often pair slope netting with a thin layer of erosion control blanket (ECB) on top to prevent the netting from being damaged by people or equipment. If a slope has a history of saturated soil or poor drainage, we’ll first install sub-surface drainage lines before applying netting, because even the best surface netting can’t stop pore water pressure from building up and causing soil failure. We also don’t recommend slope netting for slopes that are steeper than 60 degrees—even engineered artificial slopes that steep are better suited for rockfall barriers or retaining walls, since soil-based netting won’t hold in loose fill at that angle.
I also want to talk about installation, because that’s where a lot of projects go wrong. Slope netting for artificial slopes isn’t just unrolling the mesh and staking it down—poor installation will render even the best netting useless. We’ve seen contractors skip proper anchoring, only staking at the top of the slope and not along the edges or every 2 meters down the face. That’s a mistake—rainwater can get under the netting and lift it away from the slope, leading to erosion underneath. We provide our clients with step-by-step installation guides, and for larger projects, we even offer on-site training for crews to make sure they’re doing it right. On a recent 2.5-mile residential development slope project in Florida, the contractor tried to install the netting themselves without training, and ended up with a 300-foot section that had loose seams and too few stakes. We sent a team back to re-install that section, and since then, the entire slope has held up through multiple tropical storms with no erosion issues.
Another advantage of slope netting for artificial slopes is its cost-effectiveness. Compared to other stabilization methods like retaining walls, geogrids, or even regular mulch, slope netting has a lower upfront cost, and requires less long-term maintenance. Retaining walls can cost $50 to $100 per square foot, while our slope netting for soil slopes is usually less than $2 per square foot. Mulch and hydroseeding needs to be re-applied every two to three years, but our netting has a 10-year performance warranty, and the vegetation that grows through it only needs occasional trimming, not full re-seeding. For small projects, it’s easy to install yourself, and for larger projects, it works well with other stabilization methods as part of a layered approach.
I recently had a conversation with a project manager for a new shopping center in Texas that had a 25-foot artificial slope between the parking garage and a retention pond. He’d initially planned to use concrete retaining walls, but after we ran a cost comparison, he switched to our HDPE slope netting with native grass seeding. The project came in $120,000 under budget, and when he sent me photos six months later, the slope was covered in lush grass, with no signs of erosion. “I was skeptical at first,” he told me, “but this works way better than I thought it would. The netting held the soil during the heavy spring rains, and now the grass is so thick you can barely see the mesh.”
At the end of the day, the question isn’t “Can slope netting be used on artificial slopes?”—it’s “Can you use the right slope netting for your artificial slope?” For decades, slope netting was associated with wild mountain areas and rockfall protection, but engineering and material advances have made it a versatile, reliable solution for man-made slopes of all sizes. Whether you’re working on a highway embankment, a residential development, a reforestation project, or a public park, slope netting can help you prevent erosion, establish vegetation, and extend the lifespan of your artificial slope—without breaking the bank.
