Hi @kitkat20,

The first thing you'll need to address is the sunken pavers. This can't be done from above, so you'll have to lift them and address the substrate to bring them back up to level with the others. Typically, pavers will have a compacted base, which is topped with Paver Sand. I'd suggest you lift the sunken pavers, then add paver sand to bring the level up.

Gaps between pavers are typically filled by sweeping polymeric paver sand between the pavers and then wetting it down to activate the polymer. In saying this, the gaps can only be up to about 4mm in width, so if there are larger gaps that you are looking at, we may need to address them individually, possibly with mortar or by adding new pavers.

When you've done all your levelling and filling, you can seal your pavers with this Crommelin DiamondTough Coloured Sealer, tinted to the colour of your choosing. Make sure you read the instructions thoroughly and follow them closely to achieve the best results possible.

Let me know what you think and if you have further questions, please don't hesitate to ask.

Hey Jacob - thank you so much for your advice.

Before I start take out some sunken pavers, can I ask where does rain water go, does it go to soil inside the gap of paver or I neeed to make pavers in such a way that it will go to drain?

Hello @kitkat20 

If the pavers and paving gap are covered correctly, the rainwater will get diverted elsewhere and not go down your paving. If the gaps are unsealed or uncovered, it is possible that rainwater has been going down the side of the paver causing the sand to flow away. If that is the case it is best to cover the gaps with gap filling sand or sand and mortar mix.
