My new map is almost done! problem: obstacles not bullet proof!

[BufferOverflow]

Hello, I finished my first map for Day of Defeat Source today, and when i was giving it a test run i realized some obstacles were not bullet proof! I'm looking for a solution that leaves out me having to edit the sizes of blocks. Is there an easier way to just choose to make a wall bullet proof?

...or how do you create sandbags in hammer?

hey,
Maybe you can put a invisible metal wall in it so its like the obstacles are bullet proof, only you wont see any bullets after you shot on the obstacles
