Undecided ether to use aluminium or concrete copings on parapet walls on a 3 sided extension.
The roof will be covered in EPDM up the parapet and over one skin of block. Dont know should i close the cavity or not or just leave opened if im using concrete copings or will i have to continue the EPDM over the second course of blocks then the concrete copings ontop of this. If so, will i need to install anything else for the cement to bond to the EPDM.
The aluminium is straight forward to install but its pricey.
