1. Thanks for pointing me in a direction.
2. Bulging is most likely being caused by water soaking into the ground outside and then freezing causing pressure on the cinderblocks. The town repaved the road in front of the house a couple of years ago and ever since then anytime it rains my yard ends up under 2-5 inches of water. I've looked into redoing my yard but because my house was built so low to the ground the yard can't be built up enough to compensate for being low point on the street.
