SECTION 12: Interior Concrete and Foundation 12.1 Concrete Floor Uneven
12.4 Concrete Slab-on-grade Floor Cracks
Concrete slab-on-grade floors cannot be expected to be crack-free. Most cracking is minor and is the result of large areas of concrete shrinking as the concrete cures. These cracks do not affect the structural integrity of the home. Since slab-on-grade floors are quite large, shrinkage cracks can be expected to occur randomly. Cracks in slab-on- grade floors measuring ¼ inch in width or vertical displacement will be repaired by the Builder for a period of two years. Repair may include filling, grinding, or use of a floor-leveling compound. 12.5 Expansion and Control Joints Expansion joints are intentionally placed in some concrete surfaces to allow sections of concrete to expand and contract with changes in temperature, and control joints are intentionally placed in concrete to control cracking as concrete cures. Expansion and control joints often have inserted plastic barriers or have been grooved/notched during concrete placement and will have a tendency to move or crack in the joint area. Movement at a control joint in excess of ¼ inch in width or vertical displacement will be repaired. The Builder will repair excessive movement by filling, grinding, or use of a floor-leveling compound for a period of two years. 12.6 Footings and Foundation Wall Cracks Appropriate measures will be taken to correct serious cracks and/or deterioration in the foundation footings or foundation walls that cause the home to be unsafe or uninhabitable. The Builder will make the necessary repairs and/or provide replacement to the structural elements and related damage, except for areas not constructed by the Builder, for up to ten years. For a period of two years, the Builder will patch the voids in walls caused by any cracks in the foundation that exceed 1⁄8 inch in width or vertical displacement.
Interior concrete floors should not vary from flat exceeding ¼ inch per 4 feet, provided that the deviation is gradual. If these conditions exist, the Builder will repair the floor for a period of two years. Appropriate corrective actions could include filling, grinding, or use of a floor-leveling compound. Color and texture may vary from original finish. 12.2 Concrete Appearance/Finish The Builder will repair disintegration of the surface resulting in the appearance of coarse aggregate below the surface for a period of two years, unless salt or chemicals caused the disintegration of the floor. The Builder will repair the surface by patching or surface coating. Nonstructural cosmetic surface flaws will be repaired or replaced at the Builder’s discretion. Color variations are not covered by the Limited Warranty. 12.3 Concrete Cracks Cracks in garage floors, walkways, driveways, patios, and steps that exceed ¼ inch in width or ¼ inch in vertical offset will be repaired, at the Builder’s discretion, for a period of two years by filling and patching. The texture and color of concrete cannot be matched due to varying conditions and, therefore, the matching of concrete color or texture is not covered by the Limited Warranty.
