Brick Heaving In The Garden: What It Is and How To Prevent It

Brick Heaving

Have you ever noticed that some bricks in your garden or patio seem to be unevenly spaced or even raised up? This phenomenon is known as brick heaving, and it can be caused by a number of factors, including freeze-thaw cycles, poor drainage, and tree roots.

In this blog post, we'll take a closer look at what brick heaving is, what causes it, and most importantly, how to prevent it from happening in your own garden.

The Causes of Brick Heaving

Freeze-Thaw Cycles

One of the main culprits behind brick heaving is the repeated freeze-thaw cycle that happens in many parts of the world during the winter months. When water gets into the porous surface of bricks, it can freeze and expand, causing the bricks to move and shift over time.

Poor Drainage

Another common cause of brick heaving is poor drainage. If water is allowed to collect around the base of your bricks, it can seep into the soil and cause it to expand, pushing the bricks upward.

Tree Roots

Finally, tree roots can also contribute to brick heaving. As trees grow and mature, their roots can spread out and push against anything in their path, including your garden bricks.

Preventing Brick Heaving

Install Proper Drainage

To prevent brick heaving caused by poor drainage, make sure that your garden or patio has proper drainage installed. This could include a French drain, a dry well, or even just sloping the ground away from your bricks to encourage water to run off.

Use Gravel Underneath Your Bricks

Another way to prevent brick heaving is to use gravel underneath your bricks. This will allow water to drain away from the bricks and help keep them in place.

Avoid Planting Trees Too Close to Your Bricks

If you're planning on planting trees in your garden, make sure to leave plenty of space between them and your bricks. This will help minimize the risk of tree roots pushing against your bricks and causing them to heave.

Repairing Brick Heaving

Remove Affected Bricks

If you do notice that some of your garden bricks have ed to heave, the first step is to remove them from the affected area.

Repair the Soil Underneath

Once the bricks have been removed, you'll need to repair the soil underneath by removing any excess soil or debris and leveling it out.

Replace the Bricks

Finally, replace the bricks with new ones, making sure to use proper techniques to prevent future heaving.
