Method of Sealing a Core Hole

A method of sealing a core hole formed in a concrete slab having opposite first and second surfaces, with the core hole extending between the first and second surfaces, the method comprising:

• providing a seal assembly for sealing the core hole, the seal assembly comprising:
• (1) a cover assembly that includes a cover plate and a lower plate that is coupled to the cover plate through a support member;
• (2) a locking element carrier that is coupled to the cover assembly and extends from the cover assembly through the core hole when the cover plate is seated over the core hole;
• and
• (3) a locking element that is movably coupled to the locking element carrier, the locking element being configured for movement between first and second positions, the locking element being configured to pass through the core hole when the locking element carrier is passed through the core hole while in the first position, and wherein the locking element is configured to engage the second surface of the concrete slab when in the second position and prevent passage of the locking element through the core hole, the locking element being selectively movable locking element carrier to facilitate securing the seal assembly to the concrete slab;
• installing the seal assembly by passing the locking element carrier and locking element through the core hole while the locking element is in the first position;
• moving the locking element to the second position so that the locking element engages the second surface of the concrete slab;
• moving the locking element upon the locking element carrier to facilitate securing the seal assembly to the concrete slab so that the cover plate engages the first surface of the concrete slab and seats over and covers the core hole, and the lower plate member being received within the core hole and being spaced apart from the cover plate when the cover plate is seated over the core hole to define a cavity between the lower plate and the cover plate;
• and
• introducing an insulating material into the cavity between the lower plate and the cover plate.
