Why Permeable Paving Is Better Than Non-Permeable Paving

Jim Robinson • July 20, 2022

You see non-permeable paving materials everywhere in the form of concrete and sand mixtures used in patios, walkways, landscaping, and other areas where hardscape is necessary. However, there is a better way to meet these hardscape needs. Here’s why permeable paving is better than non-permeable paving.

A Gravel Base

A major difference between non-permeable and permeable pathways is one that many people may not even see. Permeable paving uses a deep, purely gravel base instead of the typically thinner mixture of concrete sand and gravel that is more difficult for liquids to move through. By limiting the base to only gravel, liquids like water are able to move deep into the pack and soak back into the soil. However, like permeable paving bases, the gravel-only base is just as stable when enduring harsher weather conditions.

Wider Joints

Another reason why permeable paving is better than non-permeable paving relates to how their joints are designed. Non-permeable paving materials have stiff joints that are filled with sand or similar materials. Permeable paving has wider joints that allow water to drain through the cracks so that it doesn’t pool on top of the hardscape. These joints aren’t so large as to make the surface rough or unstable but instead create a unique and pleasing design. Furthermore, without water pooling onto the surface, erosion is less of a concern. You can rest assured that your pavement will remain in good condition for longer with less maintenance.

Redirecting Water

We keep mentioning permeable paving’s ability to drain water back into the soil, and for good reason! In environments that have been heavily paved over with non-permeable materials, it can be difficult to keep greenery and natural elements alive and thriving. Permeable paving will ensure water is able to reach the soil and keep it healthy and nutritious for plants that line sidewalks. Permeable paving also acts as an effective protective measure to ensure the roots of trees and other plants aren’t trampled or uprooted as people go through their daily lives.

Non-permeable paving is a purely beneficial upgrade to any application. Rockpave can supply you with all the materials your municipality needs to truly thrive. Get in contact with us today!

Resin Bound Tree Pit Surrounds

By Jim Robinson • September 9, 2025

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.
