When expansion joints no longer have any sealing materials, water can leak through, and water under a concrete slab can cause big problems. Water can leak into basements and sunrooms. Water can erode the soil underlying a driveway or patio slab and the cement can collapse into the void. I’ve had the same problem with my driveway, sand washing out, weeds, moss, generally looking grubby

Also, when choosing the best area to lay your paving slabs, you’ll need to have made a couple of key decisions first - like how large you want your area to be, and how well will it drain after a heavy downpour.

Patio grout plays a huge role in reducing the amount of maintenance and time needed on your garden patio. There’s nothing worse than weeds growing through old grout on a weekly basis, forever spraying weed killer to keep them at bay as well as pouring in ant treatment to keep them from digging up sand too.

Patio grout looks great but also stops weeds and ants coming through I’ve just spend a week cleaning drive, removing few oil spots, scrapping out every trace of plant growth, sanding, then I’ve sealed with 70lt of Everbuild Patio Sealer Once you have added the MOT Type 1, it's time to add the sharp or grit sand. Begin by pouring a layer of sand onto the MOT Type 1, and use a rake to spread it evenly across the surface. The sand should be around 50mm deep.As a side note - make sure when you’re measuring out your perimeter that you take into account the small gap that you need to keep between your paving slabs (about 10-15mm) when you come to lay them.

Use a rubber mallet to tap the slabs into place and ensure they are level with one another.
