One of our jobs on this project in Crantock involves balcony screeding.
The customers want to have black limestone paving installed, but first we need to prepare the substrate.
We use two layers of wax builders paper to separate the existing balcony deck substrate from the cementitious screed.
Insulation is installed around the perimeter of the balcony which is removed after screeding, and filled with a weak 10:1 sand and cement.
This detail allows the layer of screed to move independently.
The balcony deck always get’s very hot in the summer and very cold in the winter, so there is a lot of movement via expansion and contraction.
After the prep work is complete we screed the balcony.
You will notice that we have left lengths of timber running parallel with the balustrade base rail.
This timber will be removed later and the linear drainage channels will be installed.
We now install the linear drainage channels.
The customer choose black plastic as they are having black limestone paving, but there is a huge choice of linear drainage channels available on the market today.
All ready for laying the paving which you can view on this blog post – Black Limestone Paving
