filling gaps between slabs

Euphoria1z

Hi

I have about 12 odd largish slabs on the side of my drive, which have about 1-2 inch (and deep) gaps in between most of the slabs with weeds growing.

once I've got rid of the weeds, I plan on filling these gaps with something that becomes solid so no more weeds comes out (hopefully)...

what's the best thing to use? is it mortar mix from b and q?

does this mortar mix become hard like concrete or will it stay soft ? or should I use concrete or something? will the soil beneath affect the filling that I use?

Thanks ( im clueless about these things so step by step info will be appreciated)

Whatever you use to fill the gaps the weeds will find a way to grow eventually.. you can fill with a mortar mix but eventually it will crumble and deteriorate or the weeds will force their way through.

Not the product that matters . Although I would always use a premixed bag
( the colour will be consistent. )

Its the application , you are fortunate to have wide/deep gaps . Use a fairly dry mix , good test , ball of mortar should clump together in the hand and retain shape BUT not stain the hand. You will be surprised how little water is required. Really force the mortar down , use a small pointing trowel , fill the gap , then use a chopping motion along the gap. Done correctly should last a number of years.
My Mothers Patio has lasted over 18 years , still looks good.

I brushed the mortar mix dry into the gaps on my patio & then sprayed lightly with water in a spray bottle. I saw Tommy Walsh do it this way on TV a few years ago- ( maybe Groundforce??) It sets firm and so far has lasted 8 years & is still weed free. Hope this helps.
