How much does a 'standard' 600mm x 900mm paving slab weigh
(approximately)? I want to know so I can guesstimate how many I can

If you're talking about the pressed granite sort used by local authorities,
I always reckon that a 2x2 weighs a hundredweight, and a 3x2 a hundredweight
and a half.

On that basis, one of your 600x900 (nearly a 3x2) will be about 70Kg.

Not a bad estimate.

There is a table down towards the bottom of this page on Cormaic's
excellent site.:

http://www.pavingexpert.com/pccflag1.htm

It gives approx. weight for 600x900x50 mm flags of 64 kg.

All I know is if you are trying the lay the buggers, they are bloody
heavy, and hard work to lay if you've not had plenty of practise.

I don't think I'd want to carry 5 at once in my car. OK, they weigh about
the same as 5 people - but you'll still presumably have a driver?! Also, the
distribution is likely result in far more load on the back wheels than when
you have 5 people in the car.

For most cars, 3 at a time would probably be a sensible limit.

I was fascinated to watch some cut stone paving being laid in a
pedestrianisation project. They used a neat little machine with
a big suction hose to lift and place each slab.

Look in your handbook for the maximum permitted tow hook weight to get an
idea of what the boot can cope with. You can go up slightly on that, because
the moment arm is less, but not by much. My guess would be two or three
slabs in the average car.

It depends rather whether you put the slabs behind or in front of the

can quite legitimately load the car up to its maximum permitted
weight. The car is an XM hatchback, i.e. it's a big car, and I will
lower the back seats and put the slabs where the back seats were.

The maximum tow bar weight has very little to do with the rear axle maximum
weight. Almost no car will allow more than 100kg on the towbar (whilst 75kg
is more normal) whilst the majority will allow you to exceed that as useful
load on the rear axle. Remember that when towing with a 70kg noseweight, you
are still allowed to use the boot, provided you don't exceed MAM or GTW.

As a very rough estimate, you can fill the boot with half the useful load
(MAM-kerb weight) of the vehicle. However, if you are cutting it that fine,
then you should book an appointment at a public weigh station and check it.
You will then have a much better feel for how much you can take in one go,
which may be very useful for the future, or if you will need many trips.
Note that you can't be done for being overweight on a trip to the weigh
point, provided you don't take the **** and can justify your calculations.

Overloading vehicles is dangerous and you can get really quite severe
penalties for it, but the fact that you asked the question suggests that you
have the right attitude. I saw a complete nutter loading up in B&Q a few
weeks ago. He had a Ford Tourneo (small minibus transit van) that required
him to place almost the entire load behind the rear axle. A quick
calculation showed that he loaded over a tonne into that gap. I reckon he
exceed not only MAM by around 200kg, but the rear axle weight by a whopping
500kg. I seriously considered phoning the police, whilst this nutter thought
it was a great laugh trying to squeeze in one more dense concrete block or
bag of plaster. When it comes to building materials, vans and cars are
seriously weight limited, not volume.

Christian.

I've checked the XM specifications, maximum payload is between 500 and
550kg according to model, so 5 slabs should be OK (350kg plus me).

Put this would require even loading. Check the rear axle limit and make sure
you don't exceed it. Alternatively, spread the load throughout. Put a slab
in the passenger seat and two either side of the back seat. The remaining
two can go in the boot. This will ensure you can use the full load
available.

I've also found the maximum towing weight which is way more than I
thought it was - can I even pull a two horse trailer legally, wow!

Be careful. Often the legal weight limit published by the car manufacturer
is too high for safety and is based on getting the thing going on a certain
slope. However, to prevent instability and snaking, you shouldn't exceed 85%
of your car's kerb weight, which is usually less than the published braked
trailer limit. An experienced tower could get away with 100% of kerb weight,
but don't do this until experienced and NEVER exceed 60mph with a trailer.
It isn't big, it isn't clever and may kill someone. Instability can bite
suddenly at high speed and it is very easy to forget that you have the
trailer on the back (at least it is for me, as the van is wide enough to
obscure most trailers).

P.S. When loading unfamiliar building materials, take an old set of bathroom
scales along and weigh everything before purchasing/loading.

I'm not aiming to pull anything near the manufacturer's suggested
maximum, I was just commenting that I was surprised how much it was.
In fact I doubt if I'll be towing anything in the immedate future.

The XMs have two different tow bar maximums, some are 70kg, some are

don't see that the towbar maximum has much to do with it.

I don't *think* cars (i.e. passenger carrying vehicles) have a legal
maximum weight, there are just the manufacturer's recommendations.
This certainly applies to trailers towed by cars but I'm not quite
sure about the loading of the car.

Since he was overloading a van then there would be a legal (plated
somewhere) limit for the van's maximum total weight.

There is *no* "legal weight limit" for cars in the UK. See:-

Just because there isn't a specific infringement, doesn't make it legal. I
bet if you towed a full 3500kg behind a car they'd still do you. Whether it
is under construction and use, or just simply dangerous driving or whatever,
they'd still issue a prohibition and may prosecute.

Saying to the magistrate that the fact that you've towed a 3500kg trailer
whilst the vehicle manufacturer says anything over 1300kg is dangerous, and
you'll see what I mean.

Indeed:

b. A person is to be regarded as driving dangerously if it would be obvious
to a competent

and careful driver that driving the vehicle in its current state would be
dangerous. In

determining the state of the vehicle for this purpose, regard may be had to
anything

attached to or carried on or in it and to the manner in which it is attached
or carried.

THE MAXIMUM PENALTY FOR DANGEROUS DRIVING IS 2 YEARS IMPRISONMENT.

THE MAXIMUM PENALTY FOR CAUSING DEATH BY DANGEROUS DRIVING IS 10

YEARS IMPRISONMENT.

As I said before there is no legal maximum limit. The law does not
state that if you exceed a specified trailer weight it then becomes
automatically illegal. I think you'll find in fact that there is no
maximum trailer weight specified (as a recommended maximum) for many
cars, especially older ones.

I quite agree (and so does the URL I posted) that if you exceed the
manufacturer's recommended weight it will be used as part of the
evidence if you get prosecuted for having a dangerous load or some
such. however you can't be prosecuted specifically for 'too much
weight' because there isn't a weight limit.

Chris Green

however you can't be prosecuted specifically for 'too much weight' because
there isn't a weight limit.

For the vast overwhelming majority of cars sold in the last 30 years, the
manufacturers publish a limit. Just because that limit isn't totally
supported by specific legislation doesn't mean that you won't get done for
dangerous driving by exceeding it. The manufacturers have stated that, in
their opinion, the car is dangerous to drive above that weight. If you want
to defend yourself, you have to explain why the designers of the vehicle
know less about the safe towing limit than you do.

Also, I'd guess a 'DD40' conviction would be worse on your record than a
'CU50'. Getting insurance with a DD code on your licence must be pretty damn
hard.

Note that there are loads of things you may be prosecuted for whilst driving
that don't have a specific piece of legislation. They are just prosecuted
under a general careless or dangerous driving charge.

Christian.

Well yes, but that's hardly relevant is it. There *is* a speed limit
and you can be prosecuted simply for exceeding it. You can also be
prosecuted for careless/dangerous driving if you go round a corner too
fast but lower than the speed limit. However you wouldn't thus say
"there is a legal speed limit on this corner (that is lower than the
general speed limit)".

But the manufacturer's limits are much better defined than a speed round a
corner, so although they would be prosecuted under a general provision, the
offence is likely to be accurately determined by your failure to comply with
the manufacturer's recommendations. In fact, your failure to do so can
probably be measured more accurately than your speed!

Since they were being given to me free I could hardly "have them
delivered".

Anyway we collected them five at a time last night, spread them around
on the floor with the rear seats down. The XM's self levelling
suspension coped fine, just a few clicks of the hydraulic pump after
loading them and it was back to the normal ride height. The car
handled quite normally with no problems although of course I was
relatively cautious. 400kg is well within the maximum load so that
was to be expected I suppose.

Not sure there is *one" standard as such. Edges that are 300, 450, 600mm

Do they get heavier when they've been laid a while? Maybe absorbing water?

I recently had to lift a couple of slabs when I put up my new fence, and
they were really **** heavy. Much more than the 20kg bags of postfix I
was carting around.

IIRC around 20kg

It does rather depend on the size. The last batch of 600x600x40mm slabs
I bought were 33kg each.

I've always worked on a relative density of 2.4 - for slabs in the real
world this woul be 2.4kg/li.
So, 900x600x50:
9x6x0.5=27li, times 2.4=64.8(kg).
The Paving Expert gives 64kg
