The ground was raised.
It wasn't repaired, earlier there was a piece of cardboard that kept on breaking due to water damage. So we got the floor raised to avoid further damage.
To avoid water damage to the cardboard and the trunk, we raised the floor. We tried many ways to fix this problem, using bricks and cardboard, but all failed. So we finally just raised the floor by cementing it.
It helps to protect and extend the life of our products. Saves time and money in the future.
