Description

Description

BuildBlock HardWall uses BuildLock Knockdown ICFs to create an insulated ICF wall on one side and a bare concrete wall on the other.

The BuildBlock HardWall connector extends a BuildLock web bridge 2-1/2 inches to the edge of what is normally the EPS foam. The BuildBlock HardWall connector connects to any size of web bridge. The outer edge of the connector provides an attachment point for wood, cement board, or other suit able forming material.

The end of the connector also contains a removable cap with a guide hole for screws. Once the wall is poured and the forming material is removed the cap may be left in place as an attachment point for wall finishes, or removed and the ½-in hole filled with patch or other material.

The HardWall Connector provides the ultimate flexibility to finish the concrete wall.  BuildBlock Knockdown ICF forms have multiple uses aside from the traditional ICF form. They have been used to build footing forms, pilasters and other custom structural and architectural pieces.
