In this video I explain How to calculate how many blocks or bricks needed for a wall. We appreciate your support via patreon www.patreon.com/BuildRepairandRestore
You should really include the beds and perps when calculating how many bricks/blocks. Should be 225 x 75 and 225 x 450. In your 4.8m2 example, there would 48 blocks or 288 bricks. 10 blocks in a m2 using metric blocks 60 bricks in a m2 using metric bricks Not including the beds and perps on a sizeable wall or extension, you could end up with way too many bricks. Another rule of thumb is 1kg of mortar per brick and 2kg of mortar per block. This includes both sand and cement. Example using 4:1 mix for brickwork 1 bulk bag of sand (about 800kg usually) 8 bags of cement (200kg) Total weight 1000kg = 1000 bricks.
I’m just in the middle of working out brick & block quantities for my front porch & rear extension & your video has been a great help 👍 Thanks for taking the time to make it 👍
Hi …. Can you recommend a good Sand & Cement calculator for my brick & block work, I have 2600 bricks and 500 blocks …. I’ve had a quick look online and everyone seems to be saying something different 🤪🤪🤪🤪… thanks Mark
Great vid for the novice DIY'er, could U do one on estimating rendering coverage, sand and cement quantity's, ton bag coverage etc, Great video as Always 🖖
does this also apply for pavement? same calculations? And I assume since there's no bed and perp, your above calculations should be accurately correct then
Ther is 10 concrete blocks to a sqw meter And 60 bricks to a sqw meter. That’s a good way to work it out so easier way would be to just times the high then length then times is by 10 or 60 👍 hop this top make it a bit better
Yes that’s a good way aswell, the only thing to bear in mind is it will only work for those specific standard sizes. I made the video in mind for anyone dealing with any size blocks including those in America etc so they can also calculate for themselves. Those in the UK With these standards sizes can use the 10 blocks method
Just add the prefered mm of mortar to the length and height, add it and convert it to m before dividing it to the total surface area of the wall to find the number of bricks. The brick's width is not included because on a single wall, the width is the width of the brick. Therefore, when adding mortar, it only stretches both the height and length by the prefered mm mortar. The width remains the same.
