While you can drill & fill DRY deck delamination, as can happen in foam cores or in hot environments, you can not effectively fix wet core with this method. Wet core is wet core no matter how much epoxy you inject in. Epoxy only penetrates dry rot. If the core is moist the epoxy will not displace the water and take its place. In 25 years of tearing into boats I've yet to see a cored deck or cored lamination that exhibited dry rot. It's always either wet or dry but I've never seen dry rot..
Penetrating epoxies, or thinned West System, is meant for dry not wet core fixes. Even then it does not work very well and does not penetrate as one may think it would..
