      making our cavity tray from wide dpc allows any condensation water to be collected and released from the cavity through weep-holes built into the building at the height of the dpc

    you will need to add another thin smear of mortar to the dpc before squeezing down the tray

    we also use a cavity tray above window lintels to release unwanted water 

    note; you can purchase pre made cavity trays from local builders merchants if you prefer not to make your own

       so the cavity tray is fixed between the bed joint of the first and second course of blocks above the dpc where it runs downward to the bed joint of the first course of bricks at the dpc height

    if you find this confusing don't worry we will cover this on the goldtrowel bricklaying course

    now take the blocks up putting in your cavity ties as you go
