Paving stone needs maintenance, sometimes they sink. It was another DIY
project I did it four years ago but I did not take any video at that time.
If you are interested check out the link in the description. It looks fantastic, eh?
I used to product for high-performance bedding for the base because I wanted to
avoid renting the plate compactor. However this stuff needs to be 100%
contained, otherwise this is exactly what happened. As you can see the
builder did not back fill the area under the stairs, so the HPB got wash
away and the paving stone started to sink. This is my solution. I used the
expanding form to fill the gap then I mixed the leftover self-leveling
compound from the tile project and filled all the gaps
For DIY people who never use this product before, I strongly recommended
this. This high performance padding is 95% self-compacted. You just used minimum
force to compact it. No more crusher run and limestone screening and no need to
rent the plate compactor. I used this special rubber mallet to install
the paving stone. You need to level it properly, always make a slope to drain
the water away from the house
This paving stone was made by a company called Pemacon I believe is a
Canadian company. This slab is called Rosebel, it looks like natural
flagstone, I chose this because of the random pattern. There are similar
products on the market, but they don't look as good. Bad part is that, the slab is
huge and is really heavy but is totally DIY-able.
It was supposed to be a maintenance project and there shouldn't be any
cutting needed. WRONG! Life is not always perfect
Okay... the last step is to fill the joints with polymeric sand, usually we need to
set your garden host on MIST to activate the binder and wait for a couple of
minutes. Then use the Leaf blower to get rid of the
sand on the surface. If you don't do that you will get the white haze when
it dried. Even if you use the leaf blower, sometimes there are spots that you may
have missed. This is a known trick to remove their hardened polymeric sand from
the surface. Just pour some hot water on top and you'll be able to get rid of
them very easily
The same trick can be applied to the joints if you want to remove the old
polymeric sand. It is very time consuming but it works, I think you got
the idea. By the way I'm not sure if everyone knows that's the HARIO v60 kettle
for coffee
