5 Reasons To Use Resin Bound for Tree Pit Surrounds

April 17, 2024

Urban landscapes are as much about function as they are about visionary design. Amidst the concrete and steel, trees play a critical role in softening the harsh urban environment, providing shade, improving air quality, and enhancing the well-being of city dwellers. For these reasons and more, the choice of materials for tree pit surrounds is a decision of great importance. Resin-bound surfaces are a leading contender for this task, marrying practicality with aesthetics. Explore five compelling reasons to use resin bound for tree pit surrounds.

Enhanced Durability and Longevity

The daily wear and tear of urban foot traffic is brutal to traditional surfacing around tree pits. Resin-bound surfaces, on the other hand, can withstand the harshest urban environments. Made from a hard-wearing blend of natural aggregates and polymer resin, the resulting surface is not only durable but also flexible, which is crucial in areas with shifting subsoils. Its longevity means fewer replacements, reducing the lifetime cost of a project—a critical factor for urban planners managing tight budgets.

Unparalleled Drainage

Resin-bound tree pit surrounds are also permeable, effectively allowing water and air to reach the tree’s roots. This feature is fundamental to promoting healthy tree growth by maintaining the right balance of moisture and nutrients and preventing waterlogging. The permeability also helps manage urban stormwater, reducing the load on drainage systems and consequently minimizing the risk of flooding.

Low-Maintenance, High-Performance Surface

Unlike cast iron grates that often require rust removal and resizing, resin-bound surfaces offer a low-maintenance alternative. A smooth, easily accessible surface reduces the accumulation of debris and prevents the growth of weeds, simplifying maintenance tasks. This translates to a significant reduction in labor and resources, making it a highly efficient choice for urban landscapes.

Customization and Aesthetic Appeal

Another noteworthy reason to use resin bound for tree pit surrounds is that you can customize these materials. Resin-bound surfaces are available in a wide range of colors and textures, allowing for bespoke designs that complement the surrounding architecture and landscape. You can use these materials to create a cohesive and intentional design that not only serves the city’s ecological goals but also enhances its visual appeal.

Environmental Sustainability

Resin-bound surfaces also stand out for their eco-friendly benefits. The use of natural aggregates such as gravel reduces the reliance on non-renewable resources, while the permeable nature of the surface promotes the natural absorption of rainwater and minimizes runoff. In addition, the low carbon footprint of resin-bound materials aligns well with a city’s green agenda, making it a conscientious choice for those aiming to build sustainable urban landscapes.

Resin-bound surfaces are one of the best solutions for creating lasting and beautiful tree pit surrounds. By incorporating these surfaces into future projects, you can create dynamic environments that not only stand up to the rigors of urban life but also contribute to a greener, more vibrant community. At Rockpave, we want to set your urban trees up for success by offering top alternatives to cast iron tree grates. Our resin-bound permeable pavement is the future of city design, and we’ll provide you with everything you need to bring your vision to life.

Resin Bound Tree Pit Surrounds

Resin Bound Tree Pits: The Smarter Way to Protect and Showcase Urban Trees In towns and cities everywhere, urban planners face the same challenge: how to protect tree roots while keeping public spaces clean, attractive, and safe. Traditional solutions—like loose gravel, soil, or metal grilles—often fall short. That’s where resin bound tree pits come in. What is a Resin Bound Tree Pit? A resin bound tree pit is a surfacing system that uses a blend of natural stone aggregates bound together with a clear, UV tolerant resin. Installed around the base of a tree, it creates a strong, permeable, and decorative surface that allows rainwater to drain through while protecting the soil and roots below. Think of it as a breathable shield for urban trees: tough enough to withstand foot traffic, but porous enough to support healthy root growth. Why Choose Resin Bound for Tree Pits? Permeability for Healthy Trees The resin bound surface is fully porous, meaning water and air can still reach the roots. This promotes long-term tree health and reduces the risk of waterlogging. Cleaner, Safer Surfaces Unlike loose gravel, resin bound surfaces don’t scatter, sink, or create trip hazards. In fact they help to eliminate trip hazards! They provide a smooth, stable finish—ideal for high-footfall areas. Aesthetic Appeal With a wide choice of natural stone colors, resin bound tree pits can complement surrounding paving, creating a polished, modern look in public spaces. Durability & Low Maintenance Resin bound surfacing is resistant to weeds, litter build-up, and erosion. It keeps the area around tree bases tidy without constant upkeep. Accessibility Friendly A smooth surface around tree pits is easier to navigate for strollers, wheelchairs, and pedestrians—making public spaces more inclusive. Where Are Resin Bound Tree Pits Used? City sidewalks to reduce tripping hazards and improve walkability Parks and plazas for cleaner, more attractive landscapes Shopping districts where appearance and safety matter Corporate campuses or schools to combine functionality with visual appeal A Sustainable Choice for Urban Environments! Resin bound systems align with modern sustainability goals. By ensuring stormwater naturally drains into the ground, they help prevent flooding and reduce strain on drainage systems. Combined with their long service life, a very competitive price point, they’re a future-proof investment for greener, smarter cities. Final Thoughts If you are considering the use of resin bound for your tree pits, don't just choose any resin bound product, choose one that is time tested, data driven and will sustain the demands of a harsh city environment. A good resin bound product will have similar strengths to concrete yet it will be completely pervious. Resin bound tree pits are more than just a neat landscaping detail—they’re a practical solution that supports tree health, improves safety, and enhances the look of urban spaces. If you’re planning a streetscape project, commercial landscape, or public park, resin bound surfacing could be the perfect choice for both form and function.
