Abstract: A modular water drainage device for relieving water-logged land underneath sealed and partially sealed surfaces, such as roads and buildings, is described. Vertical planks provide support to the water conduit as well as structural integrity to the module. The planks are connected to top and bottom pans, where the bottom pan serves as an impermeable trough-like structure for the collection of water. Wire screens fastened to the exterior of the module retain particulate outside the module. Openings in the top panel of the module allow a vacuum hose into the interior space between the vertical planks, for easy removal of accumulated silt. Modules can be arranged individually, connected linearly, in parallel, or perpendicular to each other. The present invention may also contain a system for controlling, recording and communicating the operation of a building ground water extraction device.

Abstract: The primary causes of moisture accumulation in sub-structures include moisture rising from the ground and inadequate ventilation within the sub-structure. A vapor barrier ventilation system is provided which uses two systems working in conjunction to successfully first circulate and then extract air and moisture from the sub-vapor barrier area. The first system includes a series of connecting perforated pipes that are covered with round aggregate and then covered by the vapor barrier to circulate air and moisture, and thereby minimize mildew and fungi in the sub-vapor barrier area. The second system consists of vent pipes connected to the perforated pipes, which create a vacuum that may be assisted by an exhaust fan to lift and extract the air, moisture and contaminants from the sub-vapor barrier area to the exterior of the structure.
