Owner pay to fix common property

Hi there having just implemented a large special levy to fix concrete cancer on the day it was finally fixed  idiscovered more in my garage ceiling. If the EC agrers csn i pay enough money to get it fixed by putting alot of money into my strata account such that i am well ahead for levies and future special levies and am exempt from paying for other work in the future.  I would like it fixed sooner rather than later especially if i want to sell in a hurry. At the moment i feel like i have an apartment without a garage that i cant sell or rent out
