ABSTRACT:
A method and device for diverting water away from a building foundation and insulating the soil surrounding the foundation. The method includes excavating a trench in the soil at least about a portion of the perimeter of a new or existing building foundation, the trench having a predetermined depth, a first side wall defined by the building foundation, a bottom surface defined by the soil having a predetermined slope extending away from the building foundation a predetermined distance and a second side wall opposite the first side wall and defined by the soil. A first insulated waterproof diverter member is placed within a portion of trench for diverting water away from the foundation and reducing the frost penetration depth within the soil surrounding the foundation. The diverter member includes a first portion positioned against the foundation defining the first side wall of the trench and a second portion positioned against the bottom surface of the trench and sloping outwardly away from the first side wall to a position proximate the second side wall. A readily installable, removable and substantially waterproof connecting member is provided for connecting the diverter member to the foundation, preventing water flow between the diverter member and the foundation and enabling removal of the connecting member to allow access to the foundation for inspection purposes and filling the trench above the diverter member with soil to a desired level.
