Hello,
maybe someone here knows:
You can lay paving stones on a gravel bed with sand in between. Sometimes I see areas in the city paved with square granite cobblestones, but there the joints are closed and solid – I assume with cement.
Is it possible to do the same in your own garden? Is the same base enough, meaning compacted gravel, or do you need a concrete foundation for that?
Good luck

Hi,
the VDW840+ can also be installed afterward, but the preparatory work involved is more extensive... No, it is not flexible, but there is a product from ecoStones that is a solid joint with a "Green" binder, a natural binder made from some kind of plant extract instead of plastic resin. This binder is reactivated by moisture (e.g., rain), allowing it to continuously adapt to the pavers (if the bond to the edges deteriorates, it is effectively restored), and cracks will naturally fill in over time... I have not personally worked with it yet, but it is said to perform very well in installations, and I find it promising because it contains no chemicals, making it a forward-looking solution...
Drainage should be carried out as planned with a drainage channel or point drain (such as a yard drain). At my home, I simply let the water from the terrace run onto the lawn, which works fine... But even if only the joints are filled with sand, it is advisable to do this because, during heavy rain, water hardly passes through the sandy joints, and dry sand takes time to absorb water downward. In strong rain, water tends to wash over the surface rather than soak through the sand... A joint filled with gravel is more ideal for drainage but is not feasible with narrow joints.

willWohnen9 Jul 2015 21:19@Illo77 Thanks. The joint with the plant extract is interesting. However, I'm always a bit skeptical about unusual new products on the market. Someone should try them for 20 years first, haha. I've never seen a joint made of gravel before—except for grass pavers filled with gravel instead of grass. Do you have concrete pavers or natural stone in your driveway and garden?
