2 part question here.
There are several of these around the house. They're about 18"x10". I want to block them off so mice and small animals can't get inside. My plan was to use 1/4" hardware mesh, cut it to the right dimensions then use Tapcon bolts (I have a box of 1/4"x 1 3/4") to secure them to the concrete.
- Does this seem like a good idea? Or is there a better or easier solution?
If it's a solid plan, I also had questions about the Tapcons:
(a) Can I use a normal hammer drill for this or should I buy an SDS? With 4 vents and 4 holes to drill per vent, I'd be looking at making 16 holes in the concrete.
(b) Once the hole is drilled, can I use an impact driver to drive the Tapcon?
