When installing natural stone pavers, one of the most important steps happens beneath the surface—literally. The base and materials used underneath your pavers play a major role in the longevity, stability, and appearance of your finished patio, walkway, or driveway. One question that often comes up is: Can plastic go under pavers?
The Short Answer: It’s Not Recommended
While plastic sheeting might seem like a simple weed barrier or moisture block, placing plastic directly under pavers is generally not recommended. Here’s why:
1. Poor Drainage and Water Accumulation
Plastic is non-porous, meaning it doesn’t allow water to pass through. When installed under natural stone pavers, it can trap water rather than allowing it to drain properly through the base layers. This can lead to:
-
Pooling and puddles beneath the surface
-
Soil movement or erosion
-
Increased risk of frost heave in colder climates
Over time, this trapped moisture can compromise the integrity of your paver installation and lead to uneven settling.
2. Weed Barrier? There Are Better Options
Some homeowners consider using plastic as a weed barrier. While it may temporarily block weeds, plastic can also:
-
Tear easily under pressure
-
Create anaerobic (oxygen-starved) conditions that harm soil health
-
Cause pavers to shift due to trapped moisture and lack of flexibility
Instead, a professional-grade geotextile fabric is a better solution. It allows for proper drainage while still suppressing weed growth, making it ideal beneath paver base layers.
3. Natural Stone Needs a Stable, Breathable Base
Natural stone pavers are a premium, long-lasting material—and they deserve a base that matches their quality. A proper installation usually involves:
-
A compacted sub-base of crushed gravel or road base
-
A bedding layer of sand or stone dust
-
Optional geotextile fabric between layers (not plastic)
This system allows your pavers to “breathe,” drain correctly, and stay level over time.
Final Thoughts – Can plastic go under pavers?
While it might be tempting to lay plastic under pavers as a quick fix, doing so can actually lead to more issues in the long run. We recommend using proper materials—like geotextile fabric, crushed stone, and leveling sand—to get the most out of your natural stone paver installation.
