(CNN Money) — Companies are stepping up to rebuild Puerto Rico.

As of Friday, corporate donations have reached $24.1 million for Hurricane Maria relief efforts — about triple the amount that had been contributed four days ago, according to an estimate from the U.S. Chamber of Commerce.

A spokeswoman for the Chamber of Commerce said she expects corporate donations will continue to grow as companies see the urgent need in Puerto Rico and as rescue and relief work shifts into long-term recovery.

The storm, which slammed Puerto Rico more than a week ago, is expected to leave behind billions of dollars in damages.

On Monday, donations totaled $8.1 million.

A series of natural disasters across North America over the past month could have tested the limits of corporate giving. Businesses pledged over $224.9 million to relief efforts following Hurricanes Irma and Harvey, according to a recent estimate from the Chamber.

Nevertheless, major companies have continued to donate in the wake of Maria.
