How to Install Interlocking Pavers
In order to reap the benefits of interconnecting pavers it is essential that they are installed
correctly and that means by diligently preparing the underlying foundation. This is an
essential step as they require a compact and stable base. The depth of the base is an
important consideration as it will vary depending on the type of use, such as a patio,
footpath or driveway. In general for light use such as a patio or footpath there will need to
be a well-compacted base of 3-4 inches to support pedestrian footfall. For a driveway that
will support light traffic and vehicles the compacted base will need to be a greater depth of
around 4-6 inches. For even heavier vehicles this might need to be up to 8 inches deep.
Whatever is appropriate the base should be well compacted and graded to provide sufficient
drainage. This might require an eight to a quarter of an inch gradient per foot to provide
sufficient drainage but either way it should provide an even and sound foundation for laying
the bedding sand. The bedding sand will need to be around 1 inch deep to provide for
levelling and to provide the stability necessary for holding the pavers in place. A good rule
of thumb is to allow for 1 cubic yard of fine concrete sand per 300 square feet of paving.
