Rats can gnaw through standard concrete? No wonder they ended up everywhere on Earth. I would love to see some video of rats chewing holes through concrete walls. A quick search on youtube did not turn up any live rats chewing concrete.
- WalterBright 9y agoI found the reference: "Seal holes in foundations of buildings or entrances to rat burrows with a minimum of 2 in. (5 cm) of reinforced mortar mixed with iron filings (from machine shops) or broken glass pieces 1/8 in. to 1/2 in. (0.3 cm to 1.3 cm) long. (You can put some glass in a tough paper bag and smash it with a hammer. Shake out the broken glass pieces into the mortar as you are mixingi t.) The glass or the filings deters rats from digging the filled holes out again before the mortar hardens." "Common Sense Pest Control" by Olkowski pg. 633
- njarboe 9y agoOk. I'll buy that. It prevents rats from digging holes in the wet mortar before it drys.
