A flood warning was issued earlier in the day and a decision was made to use a sandbag barrier rather than the metal barriers used in the last storm.
The reason for the change is due to safety concerns around the anchoring of the barrier and it moving.
Assisted by Police , Coastguard , Swanage Town Council and Envirnoment Agency - a temporary road closure was put in place to allow the barrier to be installed.
Some 30 personal were involved in filling and moving over 700 sandbags into place.
The barrier should stop any over topping and water running down to the Lower High Street.
The team redeployed this evening to check the barrier and waves against it.
