Apartment owners and residents in western Sydney's Opal Tower have expressed their anger at the ongoing debacle, as new photos reveal the impact of extensive remediation work inside the building.

After being fully evacuated for the second time last week, residents and owners are growing restless over the ongoing chaos.

Photos provided to the Herald show props being used to support the cracked building, with some being used to brace ceilings inside apartments.

A spokeswoman for building company Icon said there were about 180 "precautionary" props being used between level 10 and the basement "in case any cracking re-occurred".
