A grout plug assembly for use in forming a pipe pile system defining at least one pile assembly inner surface portion comprises a resiliently deformable plug body and a substantially rigid plug cap. The resiliently deformable plug body defining a plug outer surface, a plug inner surface, a first plug end surface, a second plug end surface, where the plug inner surface defines a plug passageway. The substantially rigid plug cap defines a cap outer surface, a cap inner surface, a first cap end surface, and a second cap end surface. The second cap end surface is rigidly secured to the first plug end surface. The plug outer surface is sized and dimensioned to engage the at least one pile assembly inner surface portion of the pipe pile system during formation of the pipe pile system.
