Block Paving on slope

[darkside121]

Hi,
ive just block paved my drive (first time doing it), part of the drive is on a slope, as we had some very very heavy rain a few days ago, and it seems to have washed a lot of the dry sand (between the blocks) away, none are moving or have any other proplems does anyone have any ideals what i can do about it, or is there nothing thanks for any help

Just put some more in when it dries up. Not saying you did anything wrong but the most common causes for this are that you either ; did not put enough in, didn't plate it as you put it in, or did it too soon after rain in which case the face of the blocks are dry but the edges are not and the dry sand sticks to the damp edges and never filters down to the base.

Of course you probably knew all this and it was just the heavy rain but i thought i'd post it anyway.
