When it comes to creating long-lasting and visually appealing hardscape features like patios, driveways, and walkways, understanding the base materials is critical. One of the most commonly debated topics in hardscape installation is: why put plastic under pavers? While many homeowners and even contractors may assume that a plastic sheet beneath pavers helps with weed control or improves drainage, this belief is not always accurate and may lead to unintended consequences.

So, why put plastic under pavers? The short answer is: you usually shouldn't. Plastic sheeting is not recommended as a base layer under pavers for several reasons. While it may seem logical to lay a plastic barrier to block weeds or prevent moisture from rising, this method can actually trap water, causing long-term damage to the pavers and the surrounding landscape. Let's break down the reasons why this practice may be harmful and explore better alternatives for your paver projects.

Problems With Using Plastic Under Pavers

The primary issue with placing plastic sheeting under pavers is water retention. Plastic is non-porous, meaning it doesn't allow water to drain through it. When water seeps into the joints of your pavers (which it inevitably will), it needs a way to escape. If a plastic sheet is underneath, the water becomes trapped between the pavers and the plastic layer, leading to puddling and soft spots. Over time, this weakens the base material and causes the pavers to shift or sink.

In addition to drainage issues, plastic does not provide any structural support. It can create a slippery surface between the base and sub-base layers, increasing the likelihood of movement. Moreover, plastic does not break down naturally and may harm the surrounding soil's health by cutting off the necessary exchange of moisture and air.

Better Alternatives for Weed Prevention and Drainage

Instead of plastic, professional paver installers recommend using a geotextile fabric. Unlike plastic, geotextile fabric is semi-permeable. It allows water to pass through while still preventing weed growth and separating the base material from the subsoil. This fabric offers the durability and drainage benefits needed for a long-lasting paver installation.

When you work with Bay Area paver installation services like Lakota Design Group, the focus is always on longevity, stability, and proper drainage. A well-installed paver walkway or patio not only enhances curb appeal but also stands the test of time with minimal maintenance.

How to Install a Paver Walkway Correctly

Installing a paver walkway isn’t just about aesthetics—it’s about building something that lasts. Here’s a brief overview of how to install a paver walkway the right way:

1. Planning and Design
   Start by mapping out your walkway with stakes and string. Determine your desired shape and size, and consider water flow and slope.
   
   

2. Excavation
   Remove grass and soil to a depth of at least 6–8 inches, depending on traffic load. The goal is to create room for the sub-base, base material, and pavers.
   
   

3. Sub-base Preparation
   Lay down a layer of crushed gravel or limestone as the sub-base. This layer helps with water drainage and provides stability. Compact it thoroughly.
   
   

4. Geotextile Fabric Layer
   Instead of plastic, install a geotextile fabric between the sub-base and the base material. This allows water to pass through while keeping the layers separated.
   
   

5. Base Material Layer
   Add a layer of coarse sand or finely crushed stone. This helps to level the pavers and ensures a snug fit. Again, compact thoroughly.
   
   

6. Laying the Pavers
   Start at one corner and work your way out, placing pavers tightly together. Use a rubber mallet to ensure they are level.
   
   

7. Edge Restraints
   Install edge restraints along the perimeter to hold the pavers in place and prevent shifting.
   
   

8. Joint Sand Application
   Spread polymeric sand over the surface and sweep it into the joints. This locks the pavers in place and prevents weed growth.
   
   

9. Final Compaction and Cleanup
   Compact the entire walkway once again to settle the pavers into the base. Rinse off excess sand and enjoy your new walkway!
   
   

With proper installation and the right materials, including a geotextile fabric instead of plastic, your paver walkway will remain stable, weed-free, and beautiful for years to come.
