Jointing with cement-based pavement joint mortar
When paving using the bonded construction method, two types of joint mortars can be used: water-permeable and water-impervious systems.
Systems capable of draining directly, drain off any moisture that occurs. Water-impervious systems however direct the moisture on the surface towards central collection points.
However, such systems must not be confused as waterproofing measures.
Cement-based systems offer the reliability of a controlled curing coupled with higher strength development. This means a distinctly higher loading becomes possible compared to systems capable of drainage.
In preparation pre-wetting of the dry covering.
Pouring out the mortar.
Spreading the slurry.
Letting the joint mortar stiffen, lightly pre-clean the stone slabs from mortar remnants.
Final cleaning with spray mist of water and coconut brush.
Alternatively the surface may also be cleaned by machine.
