Title: Innovations by Andrew J Preiksa

Introduction

Andrew J Preiksa is an accomplished inventor based in Mount Vernon, WA (US). He holds three patents that showcase his expertise in electrical leak detection methods and waterproofing technologies. His innovative approaches have significantly contributed to advancements in building safety and maintenance.

Latest Patents

One of his latest patents is a method of providing a conductive substrate for an electrical leak detection method and a board therefor. This method involves constructing a waterproof layer on a roof deck by applying an array of coverboards and a water impermeable membrane. In this leak detection method, an electrical potential is applied between a conductive detector on top of the membrane and a conductor below it. This setup allows current to flow through moisture or liquid in any leak in the membrane. Each coverboard consists of a base layer made of electrically non-conductive support and insulating material, with an upper surface laminated with a facer sheet material that includes electrically conducting material mixed into the binder.

Another significant patent is the zoned roof monitoring system. This system addresses leaks in the membrane of a generally horizontal roof support deck by dividing the membrane into separate zones. Sensors are located to detect moisture underneath the membrane. A movable scanning device, carried by a worker, has a power supply antenna that supplies power to the sensor via electromagnetic waves. The worker moves the scanning device to selected zones, activating the sensor in each zone to emit signals related to the moisture detected underneath the membrane.
