Block paving nightmare-glass slipper advice please - Block paving maintenance

[Cinderella]

I moved in to a house with a block paving drive and weed it regularly throughout the spring, summer and early autumn. Weeds grow every 2 weeks or so and it is a huge commitment keeping the drive weed free. I have learned so much on this site and now feel able to most effectively clean my drive from algae, moss & weeds. However, I need to make it level in places and am not sure what is beyond the sand directly underneath it as I saw a diagram with lots of underneath layers. Also, I'm unsure whether to put 'a mixture; between the blocks when I next clean them in the spring to stop further weeds settling and then perhaps to seal it. If anyone knows a 'Paving Expert Approved Contractor' around Chester, North West England I would be very pleased to contact them for an estimate. Many thanks, Cinders.

Hi cinders. Seems like all the pavers busy hence no reply yet. You could be hard pushed to get a contractor to do remedial work on your drive. Have you put a straight edge across the dips to see how bad they are, you can easily do by placing coins under the straight edge ie one coin/ 2 coins beneath etc: should be sub base and sharp sand beneath blocks unless it's permeable then it will be 2 ml grit in the joints. Can you post some photos to give us all a view of the dips?
