What's best for clearing brick paved driveway of weeds?

SailorSam

I'm with freya, cheapest way is with salt.
I sprinkle it on neat on things like dandelions in the lawn but on the path you can try a cup of salt mixed in a couple of litres of water.

block paving

There's a copy of the label here, which seems to suggest that PC is really only suitable for gravel

The only reason i can see for this advice is that it might leave a temporary 'staining'.
It cannot and will not 'harm' any concrete surface.

I'd always thought that block paving was made from moulded brick-shaped concrete, with brick paving made from clay bricks.

Get a bottle of glyphosate, and a plastic spray can like this:

I'm not saying get that one,but one like it. And mark clearly on the bottle that is has been used with poison/weedkiller so you do not reuse it to spray food on plants. Use the thing on a wind less day, otherwise you might kill more than you thought. And be careful at the edges, near decorative plants.

They do, and there is something very satisfying about burning the little blasted things

But, don't you just hate it when there is a but, eventually each brick paver will have a little black border.

We haven't had that happen.

Bricks and blocks are made in a kiln at massively high temperatures. There's no way the heat from a flame gun could damage them.

thats my understanding as well, concrete paving being a cheaper product. as for weeds a good quality weedkiller, a weed hook and then resand the joints

But it might cover them in a dark deposit that looks unsightly. Just a guess, I don't have a clue, but this is the internet, so knowledge is not a prerequisite.

If the blocks are concrete, it's possible that an intense heat could damage them but we use the flame gun over our paving and that hasn't been damaged.

I wonder if the terminology has changed? What we bought some years ago was called block paving but it's definitely kiln fired.

The first choice to be made is between clay bricks or concrete blocks. The pros and cons of each are listed below... Concrete

• Relatively cheap
• Plenty of shapes to choose from
• Textured blocks available
• Highly accurate sizes
• Wide choice of block depths, from 40mm to 100mm or more

• Colours fade over time
• Aggregate can become exposed over time

• Should last at least 20 years

Clay

• Prices usually slightly higher than concrete, depending on colour
• Extremely hardwearing
• Natural colour will not fade
• Patterned pavers available

• Prone to mosses
• Size tolerance is quite variable due to firing process
• Mostly square or rectangular
• Damned hard to cut
• More limited choice of block depths (60, 65 or 80mm)

Will probably outlast all of us, and our children, and probably their children as well!
