hi folks i have to build some walls in the garden and just need an extra pair of eyes on my calculations as i am not sure if they are 100% right.
i need to build a foundation .45 m wide, 36 m long and 200 mm deep. how many bulk bags of ballast do i need and how many 25 kg bags of cement.
The walls are 36 meters long .65m meters high. how many bricks, bulk bags of sand and 25 kg bags of cement do i need.
i have worked it out but it seams to be a lot of bags of cement based on a 5 to 1 ratio.
one final question due to the wall being so long do i need to leave a floating expansion gap.
cheers
jon
