Introduction
Achieving a professional finish when laying paving slabs is not just about aesthetics; it’s about ensuring durability and longevity. Whether you’re revamping your garden or laying a new pathway, the right techniques can make all the difference.
Tools and Materials
Before diving into the process, it’s essential to gather the right tools and materials. Here’s what you’ll need:
- Patio slabs: Choose the right design and material for your project.
- Cement and sand: For creating the concrete mix.
- Sub-base material: Either MOT Type 1 or concrete, depending on your choice.
- Essential tools: Shovel, trowel, rake, rubber mallet, tape measure, spirit level.
- Safety equipment: Dust mask, goggles, knee pads, rigger gloves.
Preparation
A well-prepared base is the foundation of a long-lasting patio. Here’s how to get started:
- Measuring and Marking: Use string and pegs to outline the area. This ensures you have a clear working space and can estimate the materials needed accurately.
- Clearing the Space: Remove any debris, plants, or old paving. This provides a clean slate to work on.
- Excavating the Surface: Dig up to a depth suitable for your patio. This ensures the slabs are well-embedded and stable.
- Compacting the Soil: A compacted base prevents future sinking or tilting of the slabs.
Laying the Sub-base
The sub-base is the layer that sits directly beneath the slabs, providing stability and strength.
Concrete vs. MOT Type 1 Sub-base
Both concrete and MOT Type 1 have their advantages:
Base Type | Pros | Cons |
---|---|---|
Concrete | Stable and level surface, quick and easy process | Can be more expensive, prone to cracking |
MOT Type 1 | Cost-effective, permeable | Time-consuming, requires proper compaction |

Creating the Concrete Mix
If you opt for a concrete base, here’s how to prepare the mix:
- Combining Materials: Mix cement and sand in a 1:6 ratio.
- Achieving Consistency: The mix should be thick but pourable. Adjust the water quantity accordingly.
Laying the Patio Slabs
Once your sub-base is ready, it’s time to lay the slabs:
- Wetting the Slabs: This ensures a strong bond with the concrete or mortar.
- Placing the Slabs: Lay each slab carefully, ensuring even gaps between them.
- Setting and Drying: Allow the patio to set. Avoid walking on it for at least 24 hours.
Finishing Touches
The final steps ensure your patio not only looks great but also functions well:
- Filling Spaces: Use concrete or mortar to fill the gaps between slabs.
- Cleaning: Ensure there’s no residue left on the slabs. A clean finish enhances the overall look.

FAQs
How to Lay Paving Slabs on Different Surfaces?
Laying paving slabs on various surfaces requires different techniques:
- Soil: Ensure the soil is compacted and free of organic matter.
- Sand: A thick layer of sharp sand, compacted and levelled, provides a good base.
- Grass: Remove the turf and topsoil before laying the slabs.
- Concrete: Slabs can be laid directly, but ensure the concrete is clean and level.
What are the Alternatives to Cement When Laying a Patio?
While cement is commonly used, there are alternatives:
- Sand: A thick layer of sharp sand can be used, especially for lighter slabs.
- Mortar Mix: A combination of sand and cement, providing a firmer base.
How to Lay Paving Slabs on a Slope?
Laying on a slope requires extra care:
- Ensure proper drainage to prevent water accumulation.
- Start from the bottom and work your way up.
- Use pegs and strings to maintain level.
Laying Patio Slabs: Step by Step Guide
Prepping the Area
Before laying the slabs, proper preparation is crucial:
- Excavation: Dig around 150mm across the entire area.
- Soil Compaction: Ensure the soil is evenly compacted for stability.
- Sub-base Application: Rake in the sub-base to a consistent depth of 100mm, ensuring it’s smooth and firm.
Creating Concrete for Laying Your Patio
A good concrete mix ensures stability:
- Mix Ratio: Three parts sand to one part cement.
- Consistency: The mix should be doughy and retain its shape without oozing water.
Laying Patio Slabs
Proper technique is key to a professional finish:
- Dampening: Wet the slabs to prevent them from drying the concrete too quickly.
- Placement: Gently tap each slab into the concrete, ensuring a 10-15mm gap between them.
- Setting: Allow the patio to set for at least 24 hours.
Finishing Touches
The final steps ensure a polished look:
- Gap Filling: Use a trowel to fill gaps between slabs with a concrete mix.
- Cleaning: Ensure no residue remains on the slabs.
Additional Tips from Bricklayer Glasgow
- Sand Type: For the best results, use sharp sand when laying a patio. It’s perfect for gardens and prevents pests from tunnelling underneath the slabs.
- Decorative Edging: Consider adding a decorative border by digging a gutter around the perimeter and filling it with aggregates or pebbles for an enhanced look.
