Plumbing and electrical connections can be easily added to a concrete slab foundation after it has been poured and cured.

• A. True
• B. False
• C. Sometimes
• D. Only During Pouring

Answer: (B)

The main idea is that once a concrete slab has cured, adding plumbing and electrical paths is not a simple or routine change. Concrete is dense and strong, and creating new penetrations after the fact risks cracking, damaging embedded reinforcement, and moisture or leakage problems. While some limited work can be done later through specialized core drilling or saw-cutting, these methods are disruptive, costly, and require careful sealing and possible reinforcement. In practice, plumbing and electrical layouts are planned and routed during the pour or built into walls and chases so that they’re protected and properly waterproofed. That’s why this statement is false.
