Work our how many slabs I need.

2012paddy2012

Hi. I have an Area approx 9 feet x 16 feet to patio.
I got a guy to price job.
He reckons I need 30 square meter slabs. ( is that calculation approximately correct?)

So ..

If I get 18 x 18 inch slabs which I think is the standard .slab , how many slabs do I need ?

Thanks
Paddy

9*16=144 sq feet=13.3 sq m
18" sq slab is 2.25 sq feet
144/2.25= 64 slabs
so I don't see where the 30 sq m comes from

I am wrong there a bit , I walked it this morning that what I came up with ! On putting a tape on it now after your reply it’s actually 21 feet across the garden and 9 feet out from the rear of house ...

Is that nearer 30 square meters !?

How many slabs now ( 18 x18) would you think I need ? Thanks , sorry for wrong measurement

If you look at the metric side of the tape it will tell you the distance in meters. Just measure the distance both sides and multiply together to give yourself the area in sq meters. Much easier than calculating sq meters from feet and inches.

Oh ok I will thanks , I think if they can’t get the measurement correct... not a good sign !! Thanks

If it’s a rectangular shaped patio you don’t need to worry about sq m. Just work our what each side needs and multiply the two

I get 14 x 6 slabs = 84 slabs. So 90 slabs should sort it

Ask the guy that priced it why he is saying you need 10 square meters more than what you need. Unless you are using some super delicate paving slab that you need to allow for 33% breaks or fallout there can't be any good reason. If he was allowing an extra 10% for breaks that would be fair enough but it looks like he is pulling the piss.

I think he must have just made a mistake or misunderstood what area you want slabbed.
It would be very obvious after the job was done to see how many slabs were used, no way to hide that. He would be foolish to try and get away with charging for more than was laid.

Ask him to check the quote. If he is genuine he won’t mind.

I agree with this.

He reckons I need 30 square meter slabs.

To clarify what you have been quoted for.
30 slabs of dimension 1m * 1m?
or a paved area of 30m sq?


Also verify the agreed dimensions

I have an Area approx 9 feet x 16 feet

as oppose to

it’s actually 21 feet across the garden and 9 feet out

Did the guy actually see the patio or did he quote you without seeing it?
