If block paving border have pointing behind and front tarmac shoud be strong if you don't do it still should be okay , but I always do it by myself bc it's make more tight
Yes, an here’s why
? Why Border (Jointing) Sand Is Essential:
1. Locks the blocks in place
Sand fills the gaps between the blocks, holding them tightly together and stopping movement.
2. Prevents weed growth
Proper jointing reduces space for weeds and moss to grow between the blocks.
3. Supports load-bearing strength
It helps evenly distribute weight (cars, foot traffic), preventing sinking or shifting.
4. Stops water getting under the blocks
Jointing sand reduces water ingress that could wash out the base or cause frost damage.
If the block paving border is made from typical concrete pavers or bricks, you normally should fill the joints with kiln-dried sand fine, very dry sand The sand does a few things Locks the blocks together to prevent movement Distributes loads to avoid cracking or sinking Reduces weed growth and water ingress
Yes
Yes it does kiln dry sand it's very fine sand to go in the gaps
Yes they do
I would say yes. The sand isn’t just for aesthetic purposes, it compacts down and stops any movement. Block paving has groves in the sides to allow for this and without the sand you would be allowing for movement and frost to get in
Yes all block paving needs some support for the block to sit perfect yes you would need sand all over driveway
Yes, the joints between block paving on a tarmac driveway should be filled with kiln-dried sand:
Kiln Dry Sand / Jointing Sand is used for brushing in-between joints of all types of block paving
No as they will be concreted in but you could use it to fill the small gaps to make it look abit better
Yes
Yes all paving has to have sand infill > its the sand that when compacted vibrated within the gaps that hold all the paving together like a fixed carpet that once driven on is a total m2 drive that takes the full load of car weight and spreads it out throughout the total drive area complete.
apply kiln dried sand to the area and brush into joints with a soft brush. For best results, joint the block paving
No Need for send?
Does need Send it should be laid on concrete If it was a block paving driveway all the way over then yes. Hope this helps
