As some of you know, I'm off to South Africa on Friday to deliver a series of lectures about laying techniques for block paving to the SA trade body for concrete flag and block paving. Two weeks hard slog around Jo-burg, Durban, Port Elizabeth, Cape Town, etc.....it's a lousy job but someone has to do it!
One thing they've asked me to explain is how work is temporarily restrained overnight when there's a break in work that will be resumed the following day. We used to achieve this by laying a screeder baord or a long, straight timber against the leading edge, and then driving in pins or pegs to hold it secure. Next morning, remove the timber, take up 300-400mm of the end blocks that may have loosened overnight, and start laying afresh.
Except I've no picture of this being done. We must have done it hundreds of times when I was actively contracting, but I never bothered to get a photie.
So: would it be possible for some kind soul currently laying blocks (of any sort) to set-up such an image and photo it for me? It's doesn't need to be anything grand....even if it's just, say, a couple of metres of blocks being held in place with a piece of 4x2 or similar....I just want to be able to illustrate the principle to our fellow contractors in South Africa.
In return, I'll think about you while I'm braving the full force of a South African winter next week, when the temperatures can plummet to as low as 15°C, and you are obliged to wear a jumper on some days!
Thanks!
