Cavity Wall
A cavity wall is a common construction technique where two walls are built parallel to each other with a space (cavity) between them. Think of it like a sandwich - there's an outer wall, a gap in the middle, and an inner wall. This design helps keep buildings dry and well-insulated. When people mention cavity walls in their resumes, they're usually talking about their experience building or maintaining these specialized wall systems. It's a fundamental skill in masonry and construction work, especially in residential and commercial buildings. Other terms you might see for this include "double-wall construction" or "hollow wall construction."
