Before you start to lay garden slabs, it’s important to plan your project carefully. This will help ensure that your patio is the right size and shape for your needs, and that it’s built to last.
Choosing the Right Slabs
There are a wide variety of garden slabs available, so it’s important to choose the right ones for your project. Consider the size, shape, and color of the slabs, as well as the material they’re made from. Some popular options include concrete, natural stone, and porcelain.
Measuring Your Space
Once you’ve chosen your slabs, you’ll need to measure the area where you want to build your patio. This will help you determine how many slabs you need and how to lay them out.
Gathering Your Tools and Materials
Before you start laying slabs, make sure you have all the necessary tools and materials. This includes:
- Slabs
- Gravel
- Sand
- Cement
- Spirit level
- Rubber mallet
- String line
- Shovel
- Wheelbarrow
- Tape measure
Preparing the Ground
Proper ground preparation is essential for a long-lasting patio. The ground needs to be level and firm to prevent the slabs from sinking or shifting over time.
Clearing the Area
Start by clearing the area where you want to lay your patio. Remove any grass, weeds, or other debris.
Leveling the Ground
Use a shovel to level the ground. You may need to add or remove soil to create a flat surface.
Creating a Sub-base
Once the ground is level, you’ll need to create a sub-base. This is a layer of gravel that helps to drain water away from the patio. The depth of the sub-base will depend on the type of soil you have.
How to Lay Garden Slabs on Grass
Laying garden slabs on grass requires extra preparation to prevent the grass from growing up through the slabs.
Removing the Turf
Start by removing the turf from the area where you want to lay your patio. You can do this with a spade or a turf cutter.
Creating a Weed Barrier
Once the turf is removed, lay down a weed barrier fabric to prevent weeds from growing up through the slabs.
Adding a Sub-base
Add a layer of gravel to create a sub-base. This will help to drain water away from the patio and prevent the slabs from sinking.
Laying the Slabs
Lay the slabs on top of the sub-base, using a spirit level to ensure they are level. Tap them into place with a rubber mallet.
How to Lay Garden Slabs on Soil
Laying garden slabs on soil is similar to laying them on grass, but you don’t need to remove the turf.
Compacting the Soil
Start by compacting the soil using a plate compactor or a hand tamper. This will help to create a firm base for the slabs.
Adding a Weed Barrier
Lay down a weed barrier fabric to prevent weeds from growing up through the slabs.
Adding a Sub-base
Add a layer of gravel to create a sub-base. This will help to drain water away from the patio and prevent the slabs from sinking.
Laying the Slabs
Lay the slabs on top of the sub-base, using a spirit level to ensure they are level. Tap them into place with a rubber mallet.
How to Lay Garden Slabs on Concrete
Laying garden slabs on concrete is a relatively straightforward process.
Cleaning the Concrete
Start by cleaning the concrete surface to remove any dirt or debris.
Applying Mortar
Apply a layer of mortar to the concrete surface.
Laying the Slabs
Lay the slabs on top of the mortar, using a spirit level to ensure they are level. Tap them into place with a rubber mallet.
How to Lay Garden Slabs on Sand
Laying garden slabs on sand is a common method, especially for patios that will be used for light foot traffic.
Creating a Sand Bed
Start by creating a sand bed on top of the sub-base. The sand bed should be about 5cm deep.
Laying the Slabs
Lay the slabs on top of the sand bed, using a spirit level to ensure they are level. Tap them into place with a rubber mallet.
How to Lay Garden Tiles
Laying garden tiles is similar to laying slabs, but the process can be more time-consuming due to the smaller size of the tiles.
Preparing the Surface
Prepare the surface in the same way as you would for laying slabs. This may involve removing turf, compacting the soil, or cleaning the concrete.
Applying Adhesive
Apply tile adhesive to the surface using a notched trowel.
Laying the Tiles
Lay the tiles on top of the adhesive, using a spirit level to ensure they are level. Tap them into place with a rubber mallet.
