Perimeter Drain
A perimeter drain is a system installed around the foundation of buildings to prevent water damage and basement flooding. It's like a protective channel that collects and redirects groundwater away from a building's foundation. When people mention this in their resumes, they might also call it a "foundation drain" or "weeping tile system." This is an important part of waterproofing services, as it helps keep buildings dry and prevents expensive water damage. Understanding this term is crucial for hiring in construction and waterproofing fields, as it's a fundamental service that many companies provide.
