My destructible meshes are too light, how do I make them heavier?

My destructible meshes are too light, how do I make them heavier? I cant find an option to make them heavier (Increase the mass) anywhere…
Thanks in advance for any help!

Wow, no answers? well I just had the same problem, in the Destructible Mesh settings, there are a few values to play with.

You can check the “Custom Impact Resistance”, and set the Impact Resistance higher.
Then you can also play with the Max Chunk Speed and Fracture Impulse scale.
