Technical Resources
Standards, research and guidance that shape how we work. Vector's practice is grounded in British Standards, industry codes of practice and peer-reviewed research.
Below you'll find the technical resources that inform our approach to leak detection, sensor monitoring and waterproofing quality assurance — from the standards that mandate permanent monitoring to the insurance codes that are reshaping construction site water management.
