Does the building involve split level or different floor types?
Check these locations for potential problems in barrier continuity. Amend the design using standard design details from system suppliers (if possible). Does the building involve dividing walls between units and/or garages? These situations often pose problems to barrier continuity. Consider pouring continuous slabs beneath the walls or amend the design using standard design details from system suppliers. Does the building involve a basement? Barrier locations require careful consideration at design stage – especially placement of vertical barriers. The choice of basement construction and fitout materials is also important – expert advice is recommended. Does the construction involve infill slabs? Infill slabs often cause problems.

Applying chemicals through drill holes is also possible but is rarely a viable optio
