Claims
- 1. A permanent form which is utilized for placing a basement concrete wall of a basement and which is integrated with the basement concrete wall when the wall is placed, said permanent form comprising:
- a first panel for forming an inside surface of said form, said first panel being disposed away from the basement concrete wall;
- a second panel which is spaced from said first panel and securely attached thereto, said first and second panels together enclosing a thermally insulating air space therebetween;
- a plurality of projections which project from said second panel towards the basement concrete wall, said projections having first ends adjacent said second panel and having opposed second ends, said projections forming a generally downward-directed water conduit channel therebetween; and
- a percolation layer which is configured to abut the basement concrete wall and which is secured to said second ends of said projections;
- wherein at least said first panel, said second panel, and said projections are integrally formed as a unitary structure from a hard synthetic resin.
- 2. The permanent form of claim 1, wherein said percolation layer comprises a third panel formed with a plurality of percolation holes therethrough, said holes providing fluid communication between the basement concrete wall and said water conduit channel, said third panel being integrally formed as part of said unitary structure along with said first panel, said second panel, and said projections.
- 3. The permanent form of claim 2, further comprising a plurality of anchor portions configured to extend into the basement concrete wall when the wall is placed, said anchor portions being secured to said third panel.
- 4. The permanent form of claim 3, wherein said anchor portions are formed of a soft material which is secured to said unitary structure via-two-layer extrusion, and which prevents transmission of displacements of said anchor portions to other elements of said form.
- 5. The permanent form of claim 3, wherein said anchor portions are formed as easily-cut structures which cut in response to displacement of said anchor portions, thereby preventing transmission of said displacements of said anchor portions to other elements of said form.
- 6. The permanent form of claim 1, wherein said percolation layer is formed with a plurality of inlets and wherein said projections form reservoir portions, in communication with said inlets, for receiving fresh concrete when the basement concrete wall is placed, thus securing the form thereto.
- 7. A permanent form which is utilized for placing a basement concrete wall of a basement and which is integrated with the basement concrete wall when the wall is placed, said permanent form comprising:
- a panel for forming an inside surface of said form, said panel being disposed away from the basement concrete wall;
- a plurality of projections which project from said panel towards the basement concrete wall, said projections having first ends adjacent said panel and having opposed second ends, said projections forming a generally downward-directed water conduit channel therebetween; and
- a percolation layer which is configured to abut the basement concrete wall and which is secured to said second ends of said projection;
- wherein at least said panel and said projections are integrally formed as a unitary structure from a hard foamed synthetic resin in a thickness sufficient to form a heat insulating layer.
- 8. The form of claim 7, wherein said percolation layer is formed with a plurality of inlets and wherein said projections form reservoir portions, in communication with said inlets, for receiving fresh concrete when the basement concrete wall is placed, thus securing the form thereto.
- 9. A permanent form which is utilized for placing a basement concrete wall of a basement and which is integrated with the basement concrete wall when the wall is placed, said permanent form comprising:
- a first panel for forming an inside surface of said form, said first panel being disposed away from the basement concrete wall;
- a second panel which is spaced from said first panel and securely attached thereto, said first and second panels together enclosing a thermally insulating air space therebetween; and
- a percolation layer which is configured to abut the basement concrete wall and which is secured to said second panel, said percolation layer being formed of a nonwoven fabric and having sufficient thickness such that redundant water and water leakage from the basement concrete wall is absorbed by said percolation layer and flows downwardly therethrough, whereby said percolation layer functions as a water conduit channel;
- wherein at least said first and second panels are integrally formed as a unitary structure from a hard synthetic resin.
- 10. The form of claim 9, wherein said percolation layer is formed with a plurality of inlets and wherein said projections form reservoir portions, in communication with said inlets, for receiving fresh concrete when the basement concrete wall is placed, thus securing the form thereto.
