Paving
Paving has got to be one of those jobs that everybody would like to do, but where do you start?
It's not as difficult as you might think and all the hard work is in the preparation.
If you follow these basic principles you can avoid hiring an industrial or commercial paving service, which could save you hundreds if not thousands.
Most work within landscaping needs some degree of preparation, even more so here as it's seen as a permanent feature, with a foundation to match.
Whether you're using random slabs, regular sizes, cobbles or bricks, the basics must be in place for it to last any number of years.
Three different levels are necessary, starting with the finish you want, laid onto mortar, which in turn is laid onto your foundation of gravel or concrete.
Below this, the ground must be stable enough to carry the weight of the finished product and it's use.
By this, I mean a patio carries the weight of any number of people using it over and over again, year after year.
Similarly a drive must be able to take the constant use of vehicles using it for years without any appreciable wear. A professional driveway would be laid in exactly the same way, most of which will be down to the foundation and not the finish.
As an example, a 10 square metre area, with a random flagstone finish will need;
- 10 Sq Metres of paving (+5% wastage/cutting etc)
- 50mm/1 ton of mortar (1:4 mix)
- 100mm/2 ton of concrete (1:3:6 mix)
- OR 100mm/2 ton of scalpings (stone/dust mix)
When digging out, the volume of soil for this area will be about 2 cubic tons although it'll look like twice the amount when loose.
That's a lot of barrowing so be prepared!
Laying is achieved with a smooth mortar, not too wet so that it 'bleeds' water and not too dry to appear 'dead' or non workable.
Lay methodically in rows using a level to check as you proceed.
All that remains is the jointing with a mix that is a little drier than the laying mix tooled in with a rounded bar or flat jointer.
Best prices for materials will be at builders merchants and the higher prices usually results in a better quality, so don't be dissapointed when buying cheap paving to have it fade after a couple of years.
Experience has made me a true believer in 'you get what you pay for'.
