If you live in Waco and a slab cracked after a dry summer, the first hour is the same as anywhere else: mark the crack, check the doors, then decide who should look. What to do when the house is cracking or settling is that order.
The local part is the engineer rule. Waco's permit page says a foundation on expansive soil, or soil with a plasticity index of 15 or greater, shall be investigated and designed by a registered engineer. USDA NRCS says Houston Black is the state soil of Texas, a dark sticky clay often called black gumbo. Do I need an engineer before a contractor? is the short version.
Permits for the repair
A city permit is not a bid. Waco registers contractors and issues the residential permit. Texas has no statewide foundation-repair license. Ask for the engineer name and the permit number before anyone digs. How to choose a foundation contractor is the checklist. How much does foundation repair cost? is the national range.

What it costs
This page does not add a Waco crew price because no sourced local fee schedule for foundation work was available.
Permits and registration
The City of Waco Inspection Services office issues residential building permits and registers contractors. The city's minimum foundation notes say foundations placed on expansive soil, or soil with a plasticity index of 15 or greater, shall be investigated and designed by a registered engineer. Texas has no statewide foundation-repair license. Trade contractors still show a state license for plumbing, electrical, and mechanical work.
