Redundant Holes

Any redundant holes in drywall or concrete/masonary fire wall (breaching a fire cell) require patching up. This is done easily in a number of different ways.

REDUNDANT HOLES: Concrete

One is with a compressed mineral fibre with intumescent coatings on both sides, and simply sealed in with a correct application of fire sealant. Through a slab however can be a bit different. If the area is never going to have traffic or weight on top then the same method would be fine. But if it is in the line of traffic or likely to be under furniture then the hole would require boxing (ply or like underneath), potential reinforcing (with D-rod starters) and either concrete of a fire mortar poured on top.

REDUNDANT HOLES: Drywall

Simply over patched with Gib of the same thickness as original lining and sealed if necessary.
