Claims
- 1. A porous pad comprising an absorbent matrix material impregnated with at least one protective substance that is a wood preservative or a metal corrosion inhibitor, wherein the pad is designed to be placed within a joint between members made with wood, metal or combinations thereof for protection against biotic or abiotic deterioration within the joint.
- 2. The pad according to claim 1, wherein the pad is placed within a joint between two or more members, wherein the members comprise wood, metal or combinations thereof.
- 3. The pad according to claim 1, wherein the pad after depletion of protective substance can be reactivated by impregnating the pad with additional protective substance.
- 4. The pad according to claim 2, wherein the pad after depletion of protective substance can be reactivated by impregnating the pad with additional protective substance.
- 5. The pad according to claim 1, wherein the protective substance is a wood preservative.

- 9. A method of preserving the wood or metal of a member or fastener near an interface of a joint, said method comprising:
providing a porous pad comprising an absorbent matrix material impregnated with at least one protective substance that is a wood preservative or a metal corrosion inhibitor, wherein the pad is designed to be placed within a joint between members made with wood, metal or combinations thereof for protection against biotic or abiotic deterioration within the joint; placing the pad on a surface of a first member in forming the joint; positioning an opposing member, optionally with a fastener, to form a joint at the interface between the first member and the opposing second member wherein the pad is held in the interface between said first member and second member; and joining said first and second member and to form a joint.
- 10. The method according to claim 9, wherein the pad after depletion of protective substance can be reactivated with additional protective substance.
- 11. The method according to claim 9, wherein the protective substance is a wood preservative.
- 12. The method according to claim 9, wherein the protective substance is a corrosion inhibitor.
- 13. The method according to claim 9, wherein a water repellant is combined with the protective substance.
- 14. The method according to claim 9, wherein when a wood preservative is sodium fluoride, a matrix material is not latex or sodium silicate.
