The Brew Cabin

well i got all my pavers laid and was just on with brushing the sand in the joints when the heavens opened. i vibrated up and down several times but then the sand got too wet so most joints have got plenty of sand down them, will it be ok to drive on them now? i was gonna wait till the next really sunny day and then hire whacker plate again and have another go. also should i leave putting the keybond down until i've whackered it again or put some down now? thank you for a great site....i couldn't of laid it without it :-)

As long as there's some sand in the joints, you'll be ok driving on the pavement.

If the blocks are fully compacted, then you don't really need to re-hire a plate, as you just need to brush in the sand when it dries out, and normal trafficking will settle it into the joints.

I'd leave the Keybond for a month or so, until the joints are filled and established. Why do you think you need it omn your driveway?

Are you going to post a piccie of your masterwork? :)

ok i'll not bother with the plate and just wait for a lovely sunny day then get my brush out again!! i was going to use keybond cos i thought it made the jointing sand set, or do you think it's a waste of time using it. i'll send you a piccy when it's finished.

Keybond does make the jointing sand set, but this isn't essential to the function of most pavements. It's useful where there's a problem with scour, but for the vast majority of residential driveways, it's 'over-engineering'. Scour occurs where there is a lot of fast-running surface water scooting over the pavement, dragging away the jointing sand, on civic paving schemes that are cleaned with high-volume vacuums, or on airport runways where there is jet blast. Do any of these phenomena occur on your driveway? ;)

well the wife drives outta the garage pretty fast but i'm not sure she creates any jet blast
