Artificial grass can transform any outdoor space into a lush, green canvas that’s easy to maintain – and looks fab to boot! But what happens when your pristine astroturf morphs into a bumpy mess? We could do without that! 

Lumps and uneven patches in artificial grass can certainly be an eyesore, but don’t despair—you don’t have to live with them. With a bit of know-how and the right tools, you can restore your artificial lawn to its original lustre.  

Ready to learn how? Let’s dive into the solutions that will have your lawn looking flawless in no time.

Before we get into the fixes, it’s crucial to know what’s causing those unsightly lumps. Here are the most common culprits:

• Uneven Ground: If the surface beneath your artificial grass isn’t perfectly smooth, it will eventually show through.
• Poor Installation: Incorrect installation, such as inadequate base preparation or not securing the grass properly, can lead to lumps and bumps.
• Wear and Tear: Over time, heavy use or exposure to extreme weather can cause the ground to shift, leading to unevenness.

With this in mind, let’s walk through six easy steps to restore your artificial grass. After that, we’ll explain how to prevent lumps in the future. 

1. Inspect and Identify the Problem Areas

First, take a walk around your lawn and identify where the lumps and bumps are most noticeable. Mark these areas with chalk so you can easily locate them when you begin the repair process.

2. Lift the Affected Sections

Carefully lift the artificial grass in the lumpy areas. Try to be as gentle as possible to avoid damaging the grass or the backing. If the grass is secured with nails or adhesive, remove them carefully.

3. Level the Ground

Once the grass is lifted, you’ll likely find that the ground underneath is uneven. Use a rake or a flat piece of wood to level the area. For more significant depressions or bumps, add or remove the base material (such as sand or crushed stone) until the ground is smooth.

4. Re-lay the Grass

After levelling the ground, carefully lay the grass back down, ensuring it’s stretched evenly and free of wrinkles. You can use an old brush or your hands to smooth out the fibres and blend them with the surrounding area.

5. Secure the Grass

Re-secure the grass using nails, adhesive, or whatever method was originally used. Make sure it’s firmly attached to prevent future shifting.

6. Brush and Fluff the Grass

To finish, give your artificial grass a good brushing – the best way to do this is to use an artificial grass brush. Brush the grass against the grain to lift the fibres and restore that lush, natural look.

Taking the time to properly install and maintain your artificial grass can save you a lot of hassle down the line. Here’s how to keep your lawn smooth and lump-free:

The foundation of a flawless artificial lawn starts with expert installation. Here’s why it matters: 

Professional Ground Preparation 

The key to avoiding lumps is a well-prepared base. Professionals will ensure that the ground is meticulously levelled and compacted, using the right mix of sand, crushed stone, or other sub-base materials. This prevents future shifting or settling that can cause unevenness.

Correct Layering

A proper installation includes multiple layers—sub-base, weed membrane, and the grass itself. Each layer needs to be installed with precision to ensure stability and durability. Cutting corners on these steps can lead to bumps and lumps as the ground shifts over time.

Seamless Edging 

Edging is another critical factor. Secure and seamless edges prevent the grass from moving or lifting, particularly at the boundaries where it’s most vulnerable to wear and tear.

Even correctly installed artificial grass requires ongoing care to maintain its pristine look. But don’t worry, it’s a doddle! Here’s how to do it: 

Frequent Brushing

Regular brushing helps to keep the grass fibres upright and prevents the base material from compacting. Brush against the grain with an artificial grass brush to lift the fibres and maintain evenness.

Debris Removal

Regularly remove leaves, dirt, and other debris that can accumulate on the surface. Over time, this debris can weigh down the grass, causing it to flatten and contribute to the development of lumps.

Periodic Cleaning

Cleaning your artificial grass keeps it looking fresh and prevents organic buildup underneath that could lead to ground shifting. A simple rinse with water is often adequate but consider a gentle detergent if your lawn is soiled. 

The base is the foundation of your artificial grass, so keeping it in good condition is crucial. Here’s how: 

Post-Weather Inspection 

Inclement weather, such as heavy rain, frost, or intense heat, can affect the ground beneath your artificial grass. So, if the heavens open, take some time to inspect your lawn for any signs of shifting or unevenness in the base.

Re-compacting the Base

If you notice any minor depressions or bumps, address them promptly by lifting the grass and re-levelling the base. Being proactive will prevent minor issues from becoming major problems.

Seasonal Adjustments

You may also need to make seasonal adjustments to your lawn care routine. In winter, for instance, make sure the base material isn’t susceptible to frost heave, which can cause the ground to expand and create lumps.

By investing in proper installation and committing to regular maintenance, you can enjoy a smooth, beautiful lawn for years to come without the hassle of dealing with lumps or bumps. Not a bad deal! 

Final Thoughts

By identifying the root causes, you can quickly restore your artificial lawn to its picture-perfect best.
