Hello @JasonH 

Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thanks for sharing your question about your flooring.

I can only think of two ways to possibly repair this type of damage. First is to use a Self-Levelling Compound to go over your entire flooring to cover up all the depressions made in the floor. The second is to cover your flooring with 3mm plywood or something similar. 

Using timber sheets would be the faster repair option, just keep in mind that the panel must be securely anchored to the concrete floor so there will be no chance for it to lift or buckle should moisture get into it.

Let me call on our experienced members @JacobZ95, @homeinmelbourne and @Nailbag for their recommendations.

If you have any other questions we can help with, please let us know.

Hi @JasonH I don't think there is a requirement to lay anything on the floor as an underlay as the 100's of small chips are more cosmetic as as long as the surface is clean and flat as possible. And laying anything down as an underlay will left your overall floor height and will cause issues when meeting other rooms. But I would fill those larger holes as @EricL suggested with a self-levelling compound. I would use a large measuring jug and just fill the larger ones as it's very expensive. Just be careful to not overfill them which will cause lumps. in the surface. Alternatively a masonry caulk could be used. Just apply into the larger holes and then scrape the top level with a wide spatula. Use a long straight edge to check for any high/low points and remaining bits of grit as these will cause issues with the flooring joins etc.
