I found a small section of sill plate where the bottom is rotted. Can I fill this with epoxy wood filler? Will epoxy take the weight? You can't see from the picture but the section is about 16" long and the rot goes back in a wedge shape 1/2 to 2/3 the way under the bottom of the 2x4 sill. It looks ok from the inside the basement. There will be the weight of a deck bearing down on the sill after it is fixed. Is epoxy strong enough for that weight?
