Interior Flatwork. To accommodate soil conditions in Colorado, concrete slabs are “floating,” i.e., they are not attached to the foundation walls. Basement concrete slabs are NOT a structural element of your home. The warranty coverage for basement concrete slabs is for one year only. To allow the basement floor slab to move in response to expansive soils, there is a flexible collar around the top of the furnace plenum, gas and water lines include flexible connections, and drain lines have slip joints. The basement stairs do not rest on the floor and the support posts under I-Beams are separated from the floor slab. The Builder incorporates all of these details in the construction of the basement floor because the floor will move in response to the soils. This movement will be minimized by close adherence to the landscaping recommendations, the objective of which is to prevent moisture from reaching soils around and under the residence. MOVEMENT OF THE BASEMENT SLAB RESULTS IN CRACKING. IF SUCH CRACKS REACH 3/16” IN WIDTH, OR 3/16” IN VERTICAL DISPLACEMENT, THE BUILDER WILL PATCH OR REPAIR SUCH CRACKS OR DISPLACEMENT ONE TIME DURING THE WARRANTY YEAR. SUBSEQUENTLY, FLOOR SLAB MAINTENANCE IS A HOMEOWNER RESPONSIBILITY. SIMILAR TO THE BASEMENT SLAB, GARAGE SLABS, PORCHES AND PATIOS ARE DESIGNED TO “FLOAT,” I.E., THEY CAN MOVE WITHOUT AFFECTING THE FOUNDATION. MOVEMENT AND RESULTING CRACKING WILL BE MINIMIZED BY PROPER INSTALLATION AND MAINTENANCE OF LANDSCAPING. THE BUILDER WILL SEAL CRACKS THAT REACH ¼” IN WIDTH OR VERTICAL DISPLACEMENT ONE TIME DURING THE WARRANTY YEAR. CONCRETE SLABS ARE NOT REPLACED DUE TO CRACKING.
