ABSTRACT:
A seal member is provided for use in concrete wall form construction which sealingly engages with a form bore through which a tie rod supporting the seal member and spacer cones passes so as to prevent leakage of wet concrete from the form. The seal member of resilient material is asymmetrically supported on the tie rod by means of a seal bore within a slit along the length of the seal member. The asymmetric placement causes the spacer cones to overlap and abut the inner surface of the form walls so that they serve as spreaders for location of the wall forms.
