Does artificial turf allow drainage?
Yes — absolutely. Artificial turf is designed to drain water quickly through built-in drainage holes or fully permeable backing. In many cases, it drains even faster than natural grass.
In this guide, we’ll walk you through how artificial turf drainage works, why it matters, and what to watch out for — so you can choose a lawn that stays dry, clean, and easy to love for years to come.
What Is an Artificial Turf with Drainage System?
An artificial turf drainage system ensures water flows through the turf and into the ground below, preventing puddles and water damage. It helps maintain the turf’s appearance and durability by allowing water to move quickly through the grass.
The drainage system is built right into the backing. The holes in the backing allow water to flow through the grass, directly into the base below. This means that, unlike real grass that can sometimes retain water, artificial turf with proper drainage prevents pooling on the surface.
This drainage system works effectively when the turf is installed correctly. The base layer beneath the turf plays a big role in this process. It’s usually made of materials like crushed rock or gravel, which allow water to flow away from the turf easily.
In short, artificial turf with drainage is designed to give you a beautiful, functional lawn that stays dry and looks great all year round.
How Does Artificial Turf Drain Water?
Artificial turf drains water through a simple but effective system that starts at the surface and ends below ground. Each layer plays a role in moving water away quickly and efficiently.
It begins with the turf itself.
Most high-quality synthetic grasses have a backing that’s either hole-punched or fully permeable. These small openings are not random—they’re carefully spaced to let water pass through the turf instead of sitting on top. Once rain hits the surface, it flows down through these holes almost immediately.
But that’s only part of the story. Next depends on what’s underneath — the base layer.
Beneath the turf is a compacted base layer, usually made from materials like crushed rock or decomposed granite. This layer is designed to be porous, giving water a clear path downward. If it’s properly installed, it won’t trap water—it channels it away.
The final part is the slope.
Even if your lawn looks flat, professional installers usually build in a slight incline—just enough to help gravity pull water in the right direction. Without this subtle slope, water might settle in low spots, no matter how permeable your turf is.
So, in short:
The turf lets water through, the base gives it room to move, and the slope helps it drain out. When all three work together, your artificial lawn stays dry, clean, and ready to use—no puddles, no mud, and no mess.
Different Types of Artificial Turf with Drainage System
Not all artificial turf drainage systems work the same way. Certain designs are better suited for specific conditions, like heavy rainfall or high traffic areas.
Most artificial turf products use one of two common drainage systems: hole-punched backing or fully permeable backing.
Hole-Punched Backing
Hole-punched backing is exactly what it sounds like. Small holes are punched through the turf’s backing at regular distances. These holes give water an easy exit, letting it drain through the surface into the base below.
This type of drainage has been used for decades and performs well in standard residential lawns or low-traffic spaces where heavy or constant water flow isn’t a major concern. It’s an economical solution for most normal conditions.
Fully Permeable Backing
Fully permeable backing takes drainage a step further. Instead of relying on spaced holes, the entire backing material allows water to pass through everywhere. This design helps water drain faster and more evenly across the surface. It is particularly well-suited for regions with frequent downpours and high humidity. Our artificial grass with 100% permeable backing is especially popular for pet areas, sports fields, and rainy climates.
So, which drainage system is better? It depends on your space.
- For most home lawns, gardens, or decorative areas, hole-punched backing works just fine.
- But if you’re designing a dog run, a sports facility, or a space with heavy rain or lots of foot traffic, fully permeable backing is often the smarter choice.

What to Put Under Artificial Grass for Drainage?
A proper sub-base is the foundation of good drainage. The materials you choose and how you install them can make all the difference in how well your artificial grass handles water.
Recommended Sub-base Materials
For most projects, decomposed granite, crushed limestone, and gravel are the top choices. These materials are highly porous, allowing water to flow through them quickly.
They also compact easily, providing a stable, even surface that resists shifting or sinking over time. With these materials, you can ensure that water passes freely from the turf backing into the ground below.
However, it’s important to note that using the wrong sub-base materials can clog drainage holes. This stops water from flowing properly.
Installation Quality Is Important
How you compact and level the sub-base directly affects its permeability. A professional installation ensures that each layer is evenly compressed, preventing water from pooling or finding weak spots. This not only improves drainage but also helps your artificial grass stay smooth and even, giving you a lawn that looks great and performs well for years.
Consider how well the ground beneath drains. If the soil doesn’t drain well, you may need extra steps—like adding drainage aggregate or creating a slight slope—to help water flow.
What is the best material for drainage under turf?
The best material for drainage under turf is crushed stone or gravel. These materials allow water to flow freely, preventing pooling and ensuring proper drainage. Crushed rock or decomposed granite are also excellent options as they provide stability and effective water movement.
Does Artificial Grass Need Drainage?
Yes. Effective drainage is what keeps your artificial turf looking clean, smelling fresh, and lasting longer.
Prevents Pooling and Puddles
Without proper drainage, water collects on the surface, creating puddles that not only look unpleasant but can also damage the turf’s fibers. With a well-designed drainage system, water flows away quickly, leaving the surface smooth and ready to use—even after heavy rain.
Reduces Maintenance and Cleaning Needs
A lawn that drains well stays cleaner. Poor drainage allows moisture to linger, leading to bacteria, mold, and unpleasant odors. This is especially important for pet-friendly areas, where leftover moisture can trap smells. When water flows freely, you’ll spend less time scrubbing or deodorizing your lawn.
Prolongs Turf Life
Excess moisture is the enemy of durability. Proper drainage keeps the lawn dry, preventing issues that shorten the turf’s lifespan. Over time, this means fewer repairs, less replacement, and more years of enjoying a green, healthy lawn.
How to Install Drainage for Artificial Grass?
To install drainage for artificial grass, follow these steps:
1. Prepare the Area
Clear the Site: Remove any existing grass, debris, and weeds from the area.
Excavate: Dig to a depth of about 3-4 inches, depending on the turf and drainage system you plan to use.
2. Create a Drainage Base
Add a Layer of Crushed Stone or Gravel: Spread a 2-3 inch layer of crushed stone or gravel (3/4-inch size is ideal). This layer allows water to flow through and prevents waterlogging.
Compact the Gravel: Use a compactor or a tamper to compress the gravel layer and ensure it is level.
3. Install a Permeable Membrane (Optional)
Add a Weed Barrier: A permeable fabric or weed barrier prevents weeds from growing but still allows water to pass through. Lay it on top of the gravel.
4. Add the Artificial Grass
Lay the Turf: Unroll your artificial grass and cut it to fit the area.
Anchor the Turf: Secure the turf around the edges using landscape staples or nails.
5. Fill In the Edges and Seams
Sand or Infill Material: For additional stability and drainage, fill the turf with silica sand or another suitable infill material. This helps the grass blades stand upright and promotes drainage.
6. Test the Drainage
Water the Turf: Pour water on the turf to ensure it drains properly. If there are any puddles, you may need to adjust the gravel base or add more drainage.
Proper installation of drainage ensures that water doesn’t pool on the surface of your artificial grass, keeping it dry and functional for years.
Artificial Grass vs. Natural Grass in Drainage
Both turf and grass have their advantages. But in terms of drainage, artificial grass often comes out on top.
Artificial Grass Drains Faster
Natural grass can absorb some water into the soil, but it often struggles to handle heavy rainfall. This can leave large puddles on the surface, especially in areas with clay soil or poor grading.
In contrast, artificial grass is designed with perforated backing, allowing water to quickly pass through the turf and into the sub-base. The result? A smoother, drier surface almost immediately after rain.
Artificial Grass Recovers Quicker
After a downpour, natural grass tends to remain muddy and soft, requiring days to dry out fully. This delay not only makes the lawn difficult to use but can also lead to damage from foot traffic or equipment.
Artificial grass, however, drains efficiently and dries much faster. In most cases, the lawn is ready to use within hours—no muddy footprints, no messy cleanup.
Artificial Grass Needs Less
Over time, poor drainage in natural grass can cause compaction, leading to even more pooling and a higher chance of root rot. Maintaining good drainage often requires aerating the soil, adding sand, or regrading the lawn—all of which can be time-consuming and costly.
With artificial grass, the drainage system is built into the installation, making it relatively low-maintenance. As long as the sub-base remains stable and the drainage holes stay clear, the lawn will continue to handle water efficiently with minimal effort.
What to Do If Your Artificial Turf with Drainage Is Failing?
After years of regular use, you may notice that water isn’t draining as smoothly as it once did. If puddles are forming or the lawn feels soggy after rain, it’s best to call your installer or a professional turf company. They can evaluate the situation and offer expert solutions to restore proper drainage.
While you wait for professional help, consider what might be causing the issue:
- Compacted Sub-base: Over time, the underlying base can become too dense, blocking water flow and reducing permeability.
- Clogged Drainage Holes: Dirt, debris, and organic material may gradually build up, preventing water from passing through the turf’s perforations.
- Settled Ground or Uneven Levels: Years of use can shift the ground underneath, causing low spots where water pools.
By identifying these potential causes, you can better understand what’s happening and prepare to discuss solutions with your turf professional.
