What Happens If You Lay New Turf Over Old Grass?

While it’s tempting to take shortcuts, understanding what happens when new turf goes over existing grass is essential for achieving the best results. Let’s dive into the reasons why preparation matters and what you can expect if you try to bypass this step.

The Appeal of Skipping Grass Removal

Removing old grass can be a labor-intensive and time-consuming process. So, it’s no wonder many homeowners consider the alternative—leaving the existing grass in place and simply layering the artificial turf over it. On paper, it seems like a win-win: less effort, no need to dispose of sod, and an even base for the turf.

But the reality isn’t so simple. While skipping the removal phase might seem like a shortcut, it often leads to issues that are harder to fix later on. From uneven surfaces to drainage problems, what seems like an easy solution now can create long-term headaches.

Uneven Surfaces: A Common Problem

One of the first issues you’ll notice when laying turf over old grass is an uneven surface. Grass and soil naturally shift and settle over time. If you place new artificial turf directly on top of this unstable base, bumps, lumps, and dips will eventually appear as the grass below decomposes or grows irregularly.

The result? A turf installation that looks anything but sleek and professional. Those uneven patches aren’t just an eyesore—they can also create safety hazards, especially for kids or pets who love to run and play.

For a smooth, flawless surface, the base layer must be stable and level. That requires removing the existing grass and replacing it with a compacted sub-base, like crushed rock or decomposed granite. Skipping this step often leads to disappointing results.

Drainage Issues: Water Needs Somewhere to Go

Another major drawback of laying new turf over grass is poor drainage. Artificial turf is designed with perforations to allow water to pass through and into the ground below. However, old grass can create a barrier that prevents proper drainage, leading to pooling or soggy spots after rain or irrigation.

Waterlogged areas can damage the integrity of your turf and even cause unpleasant odors over time. To ensure effective drainage, you need to create a sub-base that facilitates water flow. Without this preparation, you might find yourself dealing with puddles and performance issues sooner than you expect.

Weed Growth: The Uninvited Guests

Think your old grass will stay put under the turf? Think again. Grass is resilient, and even a layer of artificial turf won’t necessarily stop it from growing. Weeds and old grass can push through seams or weak spots, leaving your turf looking patchy and unkempt.

Preventing weed growth requires a multi-step process: removing the old grass, applying a weed barrier, and laying a proper sub-base before installing the turf. Without these measures, you’ll likely spend more time and money dealing with intrusive growth than you saved by skipping preparation.

Turf Longevity: Don’t Cut Corners

Artificial turf is an investment, and like any investment, it deserves the right care and attention during installation. When laid on a poorly prepared base, your turf is more prone to wear, damage, and structural issues. Over time, the lifespan of your turf can be significantly reduced, leaving you with a costly problem to fix.

Proper installation ensures that your turf performs as intended, providing years of durability, comfort, and visual appeal. By cutting corners and laying turf over old grass, you risk undermining that investment. A smooth, well-prepared surface not only looks better but also helps your turf stand the test of time.

The Right Way to Lay Artificial Turf

So, what’s the right way to install new turf? It starts with removing the old grass completely. This process involves cutting and lifting the sod, addressing any roots or weeds, and leveling the ground. Once the grass is gone, you’ll need to add a compacted sub-base, typically made from crushed stone or granite.

This layer provides stability and allows for proper drainage, preventing many of the issues mentioned earlier. After compacting the sub-base, a weed barrier is installed to block unwanted growth. Finally, the artificial turf is carefully laid, secured, and groomed for a flawless finish.

Yes, this process takes more effort than skipping the prep work—but the long-term benefits far outweigh the extra labor. By starting with a clean, prepared surface, you’ll create a beautiful, durable, and trouble-free turf installation.
