Permeable Paving vs. Permeable Concrete: Which Is Better?
A permeable flooring solution is designed to allow water to seep through into the ground below — in other words, it’s porous. Permeable flooring is increasingly popular for driveways, parking lots, and walkways, offering both environmental and practical benefits.
Unlike traditional concrete or asphalt, which are not porous materials, a permeable surface manages stormwater runoff, reduces the risk of flooding and erosion, and promotes groundwater recharge.
The two most common options for porous flooring materials are permeable paving and permeable concrete. Both are made from aggregates; which refers to pieces of sand, gravel, stones, or rock.
Permeable paving is made from small aggregates bound with a resin binder. Our permeable ranges Terradec and Quartz Carpet are both made from natural stones.
Permeable concrete (also known as pervious concrete) is made by mixing large aggregates with cement and water. In comparison, traditional concrete is composed of cement, water, and very fine aggregates to create a dense impermeable slab.
Why choose permeable flooring in the first place?
Stormwater management. Permeable materials help reduce and manage stormwater runoff, lowering the risk of flooding and erosion in surrounding areas. Water will flow through your permeable surface slowly, rather than pooling on the surface and risking a flood in your backyard.
Pool-friendly. This makes permeable flooring an excellent choice for pool areas. When water splashes out of the pool, it’ll drain to reduce the risk of slips and falls. Additionally, it helps direct moisture away from the pool's foundation, channeling it into the groundwater system.
Environmental benefits. By allowing water to seep into the ground, you’re supporting local groundwater reserves. Did you know that as water passes through the permeable surface, it’s also filtered? This reduces the amount of pollutants that reach natural waterways.
Meets regulations. Using permeable materials can help meet regulatory requirements for public works regarding stormwater management and environmental protection. Terradec is commonly installed on public sidewalks and in parking lots for this reason.

So, should you choose Permeable Paving or Pervious Concrete?
There are a few reasons why resin-bound permeable paving might be a better fit for your project.
Durability: The final finish is ultimately more durable than pervious concrete, since pervious concrete uses larger aggregates. The smaller stone size results in a smoother and more intensely interlocked surface, but still with excellent permeability rates.
Easy Installation: Permeable paving like Terradec and Quartz Carpet is installed by hand. Pervious Concrete requires heavy machinery for its installation.
Cost: Permeable paver systems are typically well below the price of permeable concrete.
Drying times: Pervious concrete needs longer to cure once poured.
If you’re considering any kind of permeable flooring, you’re already making a step in the right direction for better stormwater management and environmental benefits. Go one step further and choose permeable paving instead of pervious concrete if you want the best outcome in terms of durability, installation efficiency, and costs.
