How To Lay Stepping Stones

They are a cost-effective and visually appealing alternative to a fully paved path, providing a stable surface for foot traffic while maintaining a natural, organic look.

By carefully planning your path, you can:

• Create a decorative path through flowerbeds.
• Connect areas with decorative gravel.
• Build a practical walkway on a lawn.

Stepping stones also allow for creativity. You can mix and match different shapes, sizes, and colours to create a style that suits your taste, from a rustic cottage garden to a sleek, modern aesthetic.

Stepping Stones Laying Tips

So, you've decided that stepping stones are the perfect choice for your garden. Whether you're aiming for a rustic, natural look or a sleek, modern aesthetic, properly laying them will ensure they remain durable and functional for years to come.

Follow these essential tips to ensure the proper spacing, stability, and maintenance:

Dry lay to measure up

Stepping stones don't always need to follow a strict pattern or spacing. A more natural, uneven arrangement can enhance the charm of a traditional cottage garden.

• Place the stones loosely on the ground to test the layout before securing them.
• Step back and assess how they contribute to the overall design.
• For a contemporary garden, opt for precise, evenly spaced lines for a clean, structured look.

Spacing between stones

Stride lengths vary, so there's no fixed rule for spacing. However, a good starting point is to place the stones a natural stride's length apart. For a comfortable walking rhythm, a gap of around 450mm is often suitable for adults, while a smaller 100mm gap can work well for children. Walk the dry-laid path to ensure the spacing feels right for you and your family.

In the ground, not on the ground

For a long-lasting path, it is essential to embed the stones. Placing them directly on the ground can lead to shifting and an uneven surface over time.

• Digging the Hole: Dig a hole for each stone. The depth should be a minimum of 20mm deeper than the stone's thickness to allow for a mortar or sand bed. For example, a 50mm thick stone requires at least a 70mm deep hole.
• Creating a Solid Base: A solid, compacted base is key to preventing sinking and movement. You can use a tamper to flatten and compact the soil at the bottom of the hole. For softer ground, a sub-base of MOT Type 1 aggregate (50mm-100mm) is recommended to provide a firm foundation.

Sand or cement?

Both sand and cement are used for bedding, but a mortar mix provides superior stability and is the preferred method for a secure, long-lasting path.

• Sand Bed: For firm ground, a 15mm layer of sharp sand can be used. Lay the stone on the sand and tap it gently with a rubber mallet to level it.
• Mortar Bed: A semi-dry mortar mix is the most secure option. A standard mix is 3 parts sharp sand to 1 part cement. Place a bed of this mortar mix in the dug-out hole, then set the stepping stone on top.
• For Extra Adhesion: Apply a thin layer of primer or SBR (Styrene Butadiene Rubber) bonding agent to the underside of the stone before placing it on the mortar. This helps the stone adhere more securely to the base.

Finishing and Curing

Once the stones are laid and level with the surrounding ground, you can backfill the gaps.

• In a lawn: Refill the trench with soil and sow grass seed to seamlessly blend the path into the lawn.
• In a gravel area: Fill around the stones with decorative gravel.
• Curing Time: Leave your path to set for at least 24 to 48 hours before walking on it. The exact time will depend on the cement used, so check the manufacturer's instructions.

For Super Secure Stones

For the most secure installation, follow the previous steps and add this trade tip:

• Apply PVA glue to the underside of each stone before placing it on the cement bed. This enhances adhesion and reduces movement over time.
• PVA glue is widely available at most DIY stores at an affordable price.

Common Stepping Stone Issues

Even with proper installation, stepping stones can encounter common issues over time. Below are key problems to watch for and how to prevent or fix them.

Movement and Shifting

• Prevention: The best way to prevent movement is by preparing a solid, deep base using a mortar mix or a compacted sub-base of MOT Type 1.
• Solution: If a stone becomes loose, lift it, remove the old mortar bed, and re-set it following the original laying instructions.

Cracked or Damaged Stones

• Prevention: Use high-quality stones suitable for outdoor use.
• Solution: Regularly inspect your stones for damage. Minor cracks can be repaired with a suitable sealant or mortar. Severely damaged stones should be replaced to maintain a safe and visually appealing path.

Poor Drainage and Water Pooling

• Prevention: When laying the path, ensure there is a slight slope to direct water away. The use of a permeable base (like a sharp sand or MOT Type 1 layer) can also help with drainage.
• Solution: If water pools, you may need to adjust the stone's position or, in severe cases, consider installing a more comprehensive drainage system.
