Benefits of technology
[0019] The primary objective of the present invention is to improve fluid flow associated with couplings. A secondary objective is to be able to use one communicating-coupling at all four foundation interfaces. A tertiary objective is to improve the rigidity and ruggedness of couplings. Clearly, the accomplishment of these objectives will improve the capability of the associated drainage system, and do so with minimum cost and complexity. SUMMARY OF THE INVENTION
[0020] The present invention improves between-couplings and communicating-couplings with new structure that improves fluid flow, and that structure also causes the improved couplings to be more rugged. The present invention also improves communicating-couplings with structure that facilitates the use of communicating-couplings at all four interfaces. While the present invention is applicable to a large set of couplings, it is anticipated that couplings that couple between drainage mats (between-couplings) or couplings that facilitate communication with drainage mats (communicating-couplings) will be especially favored by the present invention. Preferably, the drainage mats to be used with the present invention have a nominal height of 7.2 inches and a nominal width of about one inch.
Problems solved by technology
When the porous medium used in the practice of the '404 patent makes a sharp turn, such as at a corner, there is a tendency for fluid flow to be impeded and a tendency for the porous medium not to follow the desired contour.

Embodiment Construction
[0033] The present invention includes both new improved couplings and a new method of using the improved couplings. The new improved couplings are described in detail and then the new method is described along with structure needed to implement the method. For convenience, a preferred improved communicating-coupling is described separately from a description of a preferred improved between-coupling. The invention is the same for both.
Improved Communicating-Coupling
[0034] The improved communicating-coupling of the present invention may advantageously be seen and understood with reference to FIG. 1. FIG. 1 illustrates the most common use of communicating-coupler 80. In that use, drainage mat 10 is placed against outside-form-wall 40 (earth being present on the other side of outside-form-wall 40) along the whole length of outside-form-wall 40. Where it is desired to insert a communicating-coupling, a short section of drainage mat 10 is removed and the resulting two ends of drainage ...

For use with foundation drainage systems, improved drainage mat couplers that contain at least one barrier preventing two ends of received drainage mat from touching are described. A flow enhancing gap is produced between the ends of drainage mat. Included are improved between-couplers, improved communicating-couplers, and a method of using communicating-couplers as away-couplers facilitated by use of a dam.
Description
TECHNICAL FIELD [0001] The present invention is concerned with couplings used with conduit-like structures that communicate fluids or gas. Those couplings include couplings between conduit-like structures and couplings that allow communication of fluids or gas into or out of conduit-like structures. More particularly, the field of the present invention involves conduit-like structures that contain a porous medium or conduit-like structures that include a porous medium. The couplings of the present invention have particular utility when used in the practice of the foundation drainage system of U.S. Pat. No. 6,669,404 and when used in the improved foundation drainage system disclosed herein. DEFINITIONS [0002] Herein, references to porous medium include drainage mats, and vice versa. The preferred drainage mat to be used with the present invention has a nominal height of 7.2 inches and a nominal width of about one inch. [0003] The couplings described herein all include at least one sl...
