Patio Slabs

kbarnesie

I have moving patio slabs.
Each time I power-hose, the movement gets worse as the sand is blasted out.
I re-sand but is there a more long term solution.

Should I mix some cement with the sand, brush it in and water ?

What is the ratio of cement to sand ?

You can buy a product called permajoint

You simply brush into the gaps and it goes hard in a day.It doesnt stain the slabs either...which you can get with normal sand/cement mx.


Most builders providers and also any good patio/paving centre will have it in stock.:)

You would need to sort out why the slabs are moving. Lift, re-set securely before re-doing joints.

Like most things, anything done incorrectly, is usually when problems arise.


If done correctly, sand and cement will not stain. FACT.

yeah, i second that, there's nothing wrong with sand and cement if done propoerly, and it would be cheaper than buying a proprietary jointing product. if the mix is right and care is taken it won't stain
