Paving & Patios
All our patios are laid on a full bed of wet sharp sand and cement mix at 7/1 ratio. They are then wet pointed with a 4/1 wet sand and cement or resin. The only exception to this is when the type of slab being laid requires it to be “butted up”, they are then laid on dabs to allow for free drainage underneath. This is done to eliminate the likelihood of the slabs coming off the bed due to frost if the water is not allowed to run away.
Over the years we have found that wet pointing or resin is the most effective way of jointing slabs. A dry mix watered in invariably erodes very quickly and allows unsightly weeds to grow in the paving.
We will not lay on a dry bed or partially dry bed that has been mixed with cement. They will move over a period of time, it is a cheap way of completing a job and is not cost effective.
