It may seem crazy, but installing block paving is much more complex than just laying some bricks on the ground! There are up to 10 steps that when followed, will ensure you will have the perfect surface every time.
Although every driveway has its own unique set of challenges - it is imperative that the right preparation is undertaking to prevent expensive alterations during and at the end of the build. As part of this, we recommend a detailed construction drawing is created, with all measurements taken for the whole site which includes where all the communication cables are located for internet and TV.
The "destructive" part of the build. As block paving is build on layers, e.g. the ground, sub base and course sand, a digger will need to be hired to dig off around 200mm off the surface. This will form the base layer, which essentially is the ground. This is an important step required to ensure there is appropriate drainage installed (as this is the only time there will be nothing impeding construction).
This is required to fill into the space that was left by digger, and is where the intricate work starts. The sub bases main use is to provide a permeable layer to the ground (to help for draining) but also is the layer a membrane is installed to help stabilise the sub-base from the next layer.
Laying Course Sand
Sand is used to assist in placing the blocks of paving together appropriately. As it is the layer that is closes to the surface, it is important that it is laid smooth and even for the bricks. As part of this step rain run off will also be considered. So, if a slope is required as part of the build, this will be incorporated with the gradient in the course sand. We also suggest installing a weed control membrane, to help minimise the amount of weeds that grow between the blocks over time.
Laying the blocks
This is where the skill of the block paver comes into question, to make sure the driveway has the kerb appeal you are after! The skill here is to create a pattern that no only looks nice but is able to fit within the space available for the driveway. Typically at the edges, the block paving is sawn, to ensure the finish is not compromised.
To ensure all blocks have been laid in a straight line, once the blocks have been installed a simple solution of a piece of string from one end to the other fishes out any uneven lines.
Jointing and compacting
This is the final task, which uses jointing sand to fill the gaps between the blocks and is then compacted using a vibrating plate.
And voila, your new driveway is now installed! To learn more about block paving driveway installation visit us.
