The DIY Paving Project: Can a Beginner Do It?
Laying your own paving blocks or slabs is a challenging but highly rewarding DIY project. By doing it yourself, you can save thousands of euros in contractor labor. However, paving requires physical effort, precision, and adherence to structural principles. If you rush the preparation steps, your paving will shift, sink, or pool water.
This guide breaks down the paving process into simple steps designed for absolute beginners.
Step 1: Excavation and Ground Preparation
Mark out the area using stakes and string. You must dig out the ground to a depth that accounts for your sub-base, sand bed, and the paving slab. For a light-traffic garden path or patio, dig down **150mm**. Ensure the bottom of the trench has a slight slope (about 1:80 fall) away from any walls to guide rainwater run-off.
Step 2: Laying and Compacting the Sub-Base
The sub-base is the most important part of the project. Pour in **MOT Type 1 / Clause 804 crushed stone** to a depth of 100mm. Rent a petrol plate compactor (wacker plate) from a local tool hire shop and run it over the stone at least four times until it is rock-hard. This prevents the ground from shifting later.
Step 3: The Screed Sand Bed
Spread damp sharp sand over the compacted sub-base to a depth of 30mm. Use two steel screeding rails and a straight wooden board to level the sand perfectly flat. Once leveled, **do not step on the sand bed** before laying your blocks.
Step 4: Laying Blocks and Jointing
Start from a straight edge or corner. Place the paving blocks directly onto the sand, keeping them tightly together. Use a rubber mallet to tap blocks into position. Once all blocks are laid, sweep kiln-dried silica sand into the joints. Run the plate compactor over the finished blocks (use a rubber mat on the compactor to protect the blocks) to lock them permanently into place.
