A retainer is disclosed to act as a substrate for nailing or screwing to with insulating foam board and concrete, particularly to insulating foam board used as a foam for pouring concrete. The retainer has a head with a face adapted to receive and anchor fasteners such as nails or screws, an elongated arm extending substantially perpendicularly from said head on the side remote from such face. The arm has means to embed the arm in concrete during pouring such that the arm will not retract from the concrete after the concrete has hardened. Optionally, the retainer has a clip to attach to a tie rod extending between concrete forms, to position the tie rod with respect to the forms. The retainer is put in place before the concrete is poured. After the concrete hardens, wall surface materials and the like can be screwed or nailed to the face.
