Hey everyone,

I’m seeing more cases of plumbing failures caused by expansive soil, especially in slab-on-grade homes. Soil movement (shrink/swell) seems to put stress on buried pipes, leading to cracks, leaks, and loss of proper slope.

Common issues I’ve noticed:

• Pipe separation or cracking
• Sewer line slope getting disturbed
• Repeated leaks under the slab

Curious to hear your experience:

• What’s the most common root cause in your projects?
• Is it more of a design issue or installation problem?
• Have solutions like isolating plumbing from soil movement actually helped?

Would appreciate any real-world insights or fixes that worked for you.
