ABSTRACT:
A timber pile protection apparatus includes a sleeve that has an open first end, an open second end and a peripheral wall extending between the first and second ends. The sleeve is positioned on the timber pile. The first end is positioned nearer to a bottom end than a top end of the timber pile. The sleeve is positionable in an unrolled position extending upwardly from the first end or in a rolled position rolled downwardly to the first end. A tether has an attached end and a free end. The attached end is attached to the sleeve adjacent to the second end of the sleeve. The tether has a length greater than the sleeve. The free end extends outwardly from the sleeve when the sleeve is in the rolled position and is graspable to be pulled upwardly and unroll the sleeve to the unrolled position.
