How do you know if a Boerne home still has cast iron drain pipes?

Many Boerne homes built from the 1950s through the early 1980s used cast iron for the main drain line and sewer lateral. A CCTV sewer camera inspection can confirm the pipe material and show corrosion, tuberculation, cracks, or bellies in line. Common homeowner clues include recurring clogs, sewer gas odor, and rust-like debris in drains.

Is trenchless CIPP lining a good option for cast iron drain pipe repair in Boerne?

CIPP trenchless pipe lining can be a strong option in Boerne when the cast iron pipe is heavily corroded but still has enough structure to support a liner. After descaling with tools such as high-speed cleaners and clearing obstructions, an epoxy-saturated liner is installed using inversion and calibrated to create a sealed pipe within the existing line. Severe collapses or major sags may require pipe bursting or sewer line replacement.

Why do cast iron sewer lines fail in Boerne and Kendall County?

Kendall County soil and terrain can stress rigid cast iron. Texas Blackland clay expands and contracts with moisture, and limestone areas can contribute to uneven support. Inside the pipe, corrosion and tuberculation can narrow flow, while hydrogen sulfide gas and moisture can accelerate internal deterioration. Over time, joints can crack, roots can intrude, and bellies in the line can form, leading to backups or under-slab leaks.
