Are the pavers wet too or just the sand in the joints?

thanks for reply. sand is wet and edge of blocks.i think there might be building sand between blocks. i am going to wash this out and put kiln dried sand in and see. what else do you think it could be? there was never a drainage problem before i had my drive laid. do you recomend sealing the drive in a few months?

Damp jointing sand can result from sub-surface water being wicked (wicked as in a candle wick, not wick-ed as in evil) to the surface. If this problem does not disappear, it suggests the laying course and possibly the sub-base are not free draining and are actually retaining water. The only 'escape route' for trapped moisture is bvia the joints, driven by evaporation with the jointing sand acting as a conduit.
