So here are 5 tips that you can keep in mind while installing interlocking pavers

The Base is Important

For the best paving installation, it is necessary to have a solid and flat base. Start by removing any unnecessary and unstable base materials. You want to have the base as smooth and tight as possible.

When you are ready with a base that is smooth and free of debris, then you can go ahead and start with the compacting of the base. The height of the base will depend on the use of the paver. If you are going to use it for the normal walkway, then 4” base will do the job. In case of heavier loads, it is better if you for a 6”-8” height as it will keep the installation stable.

Good Sand Bedding is Necessary

During this step, a layer of sand is spread on top of the compacted base. The sand helps to interlock the pavers in a seamless and clean manner. Choosing the right sand in the first place is as important as doing a fine sand bedding job. You want a type of sand that is sharp and granular with an equal grain size.

The sand bedding depth should be an inch in height. Use sharp guides and screeding boards. After putting the sand layer, smooth it off with a smooth motion. Later, fill in the guide gaps with soft sand. Make sure you don’t walk on the sand bed.

Put Edge Restraint

An edge restraint will keep the lateral movement of the sand bed and the pavers in check. These hold the pavers securely in their place. It is possible to use an existing edge as a restraint, for example, the edge of the house or the garage.

If that’s not the case, then you can always use factory made polyethylene restraint. You will have to use a concrete restraint if your pavers will be used for the driveway.

Lay the Pavers

It’s time to lay the pavers. Start from one corner and do not disturb the laid sand bed. It is better if you leave a gap of 2-3mm between each unit. Keep a regular check on the straight lines; carry a string to make it easier.

Vibrate and Sand the Pavers

When you are done with placing the pavers, spread a layer of sand on top of them and run a vibrating plate compactor to set the initial interlocking process. A single pass will be enough if done correctly.

After the initial pass, lay another 1” layer of sand smoothly over the pavers and start running the vibrating plate compactor to fill the gap between the pavers. Run till every paver is set in its place. Blow off or clean the excess sand.

Your new interlocking pave is ready.
