  • Concrete should be sealed annually after installation using a quality product following manufactures’ directions.This process is a matter of homeowner maintenance and is not included by your builder. Proper sealing and regular re-application will help to limit the absorption of corrosive materials. 

    Please use a Low Gloss Acrylic Sealer or Low Gloss Water Based Acrylic Sealer. These products can be found at:
         -  Dunrite Concrete Equipment
         -  Unicon Concrete Specialties
         -  Northland Construction Supplies
         -  Hard Rock Developments
     

  • Avoid any contact with freshly poured concrete (Green Concrete) for a couple of days to minimize any surface damage.

  • Do not drive or park on freshly placed concrete driveway or sidewalk for at least 28 days.

  • Do not park or drive heavy commercial vehicles, including large moving trucks, on new residential driveways ever.

  • Avoid any large amounts of water to be placed next to any concrete pad to avoid soil destabilization. If soil destabilization occurs that could lead to structural concrete cracks.

  • Remove any type of foliage from the top of any concrete surface to avoid staining.

  • Do not use acid to clean your concrete pad and keep any type of fertilizer away from and off any type of concrete surface.

  • Excessive pressure from pressure washers can damage concrete surfaces. Using a stiff broom and concrete cleaner is a preferable method for cleaning concrete.
     

Must Do's

  • Remove all snow, ice or slush that accumulate on any concrete surface in a timely manner. Over time, freezing and thawing of un-removed snow and ice will cause the surfaces to deteriorate. The chemicals found in road de-icing methods will deteriorate any concrete surface if not removed in a timely manner.
  • DO NOT use any de-icing chemicals or salt. This method of snow or ice removal will deteriorate any concrete surface. Damages from salts, de-icers or fertilizers, including that are contained in road slush are NOT covered by warranty.

Damages from salts, de-icers or fertilizers, including those contained in road slush are NOT friends to concrete.
 

Things that MAY occur

Listed below are a few items that could occur with your concrete slab and are considered to be NORMAL and deemed to be ACCEPTABLE by New Home Warranty; they are as follows:

  • Concrete cracks providing the cracks are NOT in excess of 3mm (1/8 inch) for interior concrete or 6mm (1/4 inch) for exterior concrete.
  • Concrete scaling, spalling or pitting providing it does not exceed 10% of surface area. Surface scaling of exterior concrete is not a structural defect, and in the event that such deterioration occurs, this will be deemed to be within warranty coverage (providing it’s not caused by salts, abuse or lack of maintenance). CF Construction shall have the surfaces of exterior concrete flatwork repaired by either sandblasting or top coating it followed by sealing the slab in order to restore a uniform appearance.
