Bond Beam Build



The bond beam formwork is made up of the column formwork that was salvageable.  A streak of cold and cloudy weather made it so more formwork could be reused.  The blistering sun often saps the moisture from the wood causing cracks and splits that compromise the integrity of the formwork.  (Note)  On the same note during the hot and sunny days, when formwork is dismantled it is beneficial to wet the exposed concrete a few times a day for a few days so the moisture is retained at a pace that increases the strength of the concrete.  Formwork joints are staggered from exterior to interior and a gusset is installed at each joint.
