Just got some bricks left over. I am thinking of using them to edge my circular lawn. Anybody got any tips how to go about it for a newbie. Thanks

    If you want them to stay put you'll need to bed them in to concrete. Of you don't mind a bit of movement you really could just bury them so only 10mm or so protrudes above the surface, or flush, all neatly in line of course.

    I'd suggest measuring the diameter of the lawn, dive by two to get the radius then calculating the perimeter (multiply the radius (say 200cm) by itself (so 200 x 200) and then multiply the answer by 3.14. Divide the answer by the length of the bricks in cm, so you are not mixing your units up, which will tell you roughly how many bricks are needed if they lie along the side).

    Then, because that row of bricks makes the entire circle larger, calculate the new perimeter including the gap between the next course/divide by length of bricks again), rinse and repeat as necessary - to see whether you have enough bricks for the number of rings around it that you want.

    Can't be much more irritating than running out of bricks a couple of foot from finishing.


    If you don't do Maths, you'd have to lay them out around the edge to make sure.
    I could dream to wide extremes, I could do or die: I could yawn and be withdrawn and watch the world go by.

    It is many, many years since I did this at school, but you just described how to get the area of a circle (Pi x R squared) surely to do a boundary he needs the circumference (Pi x D)?

    Come on people, it's not difficult: lose means to be unable to find, loose means not being fixed in place. So if you have a hole in your pocket you might lose your loose change.

    Totally wrong, he doesn't want to cover it in bricks.
