The invention provides a seal for placement between a washer plate of a rock bolt and a rock face, wherein the washer plate has an outer edge at a perimeter thereof and wherein the rock bolt has a longitudinal axis, wherein the seal comprises a body made of a spongy material, wherein the body is planar and has an outer dimension that matches that or that is larger than that of outer edge of the washer plate and an inner dimension that has a void towards the center of the inner dimension through-which the longitudinal axis of the rock bolt can pass. The seal is for preventing the leakage of cementing grout (that is used in securing the rock bolt in a bore hole in a mass of rock below a rock face) between the washer plate and the rock face.
