To lay paving slabs effectively, it is essential to follow a systematic approach that ensures durability and aesthetic appeal. Start by thoroughly preparing the designated area for your paving project. This involves accurately measuring and marking the perimeter of the patio or paving area with stakes and string to clearly outline your layout.

Once you have defined the area, proceed to remove any grass, weeds, and topsoil. Dig down to your desired depth, typically between 150mm and 200mm, to create a solid foundation. Pay special attention to establishing a slight slope or fall, typically 1 in 80, to facilitate proper drainage away from your home, thereby preventing water accumulation that could lead to structural issues.

Next, create a stable sub-base by applying a layer of compacted hardcore or MOT Type 1 aggregate, approximately 100mm thick. This will provide a robust support system for your paving slabs. Compact this layer thoroughly using a plate compactor or similar tool to achieve a firm, even surface.

Now, it’s time to mix your mortar. Combine sharp sand and cement in a 4:1 ratio, gradually adding water until the mixture reaches a consistency similar to that of toothpaste — workable but not too runny. This will ensure adequate bonding when laying the slabs.

Spread the mixed mortar evenly across the prepared sub-base, aiming for a thickness of between 30mm and 50mm, depending on your slab thickness and the specific requirements of your project. Once the mortar is applied, carefully lay the first slab on top of the mortar bed. Use a spirit level to check that it is perfectly level and well-supported on all sides.

Continue the process by laying subsequent slabs, utilizing spacers to maintain uniform joints between them. This ensures a consistent appearance and allows for proper drainage. With each slab, gently tap it into place using a rubber mallet, which will help establish a strong bond with the underlying mortar without damaging the slab.

Once all the slabs are laid and aligned, allow the mortar to cure adequately. Once cured, fill the joints with an appropriate grout or pointing compound to further enhance stability and prevent water ingress, ensuring that your paving is both functional and visually appealing for years to come.

 A sample section of the document is listed below:

Laying slabs

1. Set up two string lines 80mm above the type 1 sub base, ensuring they are taught, parallel, and the same width as the slabs.

2. Using sharp sand and cement mix a 1:6 mortar and shovel a 40mm gauge onto the sub base.

3. Drag the corner of a shovel through the laid mix to create wave effects on the surface.

4. Lay the slab flat and tap into place using a rubber mallet, ensuring it is level and square.
