The Pig Brig Trap System can withstand a lot of pig damage, but occasionally you will get tears in the net. Small tears (~2-3 mesh squares) can be repaired with zip ties or hog rings. Just watch those types of repairs for stress on the surrounding mesh squares. Larger tears can be repaired with a patch kit and lashing techniques.
There are loads of good net repair videos on YouTube. See video on repairing a net. We are working on videos specifically for Pig Brig Traps, so stay tuned. Here's a PDF that demonstrates the lashing technique. If you have any questions or concerns, give us a shout. If something crazy happens, we will get you help or a new net.
