Claim:
Apparatus for securing a foundation form disposed on a moisture barrier membrane comprising: a stake comprised of an elongated body extending along a defined axis and formed of a rigid material, said stake extends from a head forming a first end of an upper portion of said elongated body to a tapered tip forming an opposing second end of a lower portion of said elongated body; a sealing member disposed at a location along a length of said stake forming a seal around a periphery of said stake at said location and extending radially away from said axis; and wherein said upper portion comprises a frangible section separable from a remainder of said elongated body at a location defined by at least one break-point where said elongated body includes a modified section which is configured to provide a reduced shear strength as compared to a remainder of said elongated body, said modified section comprised of a bore formed in said elongated body transverse to said axis, and a scored portion on the outer surface of said elongated body aligned with said bore which further reduces a cross-sectional area of said elongated body at said break point.
