Concrete
Exterior concrete is a durable surface often used for driveways, sidewalks, and patios thanks to its strength and resistance to weathering. However, it can be impacted by Alberta’s freeze-thaw cycles and heavy loading. Proper installation, sealing, and maintenance help sustain its appearance and functionality throughout the years.
Warrantability
Alberta New Home Warranty Standards:
- 1-Year Warranty: Exterior concrete (e.g., driveways, patios) may be covered under Alberta’s one-year materials and workmanship warranty for defects resulting from poor installation or material failures.
Builder’s Warranty:
- 1-Year Warranty: Builders commonly provide a one-year workmanship and materials warranty that can cover cracks due to improper installation or finishing techniques (e.g., shrinkage cracks, surface scaling).
- Issues from normal wear and tear or homeowner neglect are excluded.
Manufacturer’s Warranty:
- There is typically no manufacturer or extended warranty on poured concrete.
Maintenance
Sealing
- Apply a high-quality concrete sealer every 2-3 years to prevent moisture penetration and scaling caused by freeze-thaw cycles.
Snow & Ice Removal
- Avoid using de-icing salts, as they can damage the concrete surface. Use sand or non-corrosive alternatives for traction during winter months.
Cleaning
- Sweep regularly to remove debris and use a pressure washer annually to clean the surface and maintain its appearance.
Joint Maintenance
- Inspect and refill expansion joints with a flexible sealant to prevent water infiltration.
Professional Servicing
- Engage professionals for repouring or resurfacing exterior concrete, especially if cracks or spalling impacts its usability.
Common Issues, Warrantability, and Repair Solutions
1. Hairline Cracks
Warrantability:
- 1-Year Builder’s Warranty: Cracks that are beyond the tolerances set by municipal guidelines may be covered under the one-year materials and workmanship warranty.
- Cracking due to shrinkage or minor settling is not covered under normal warranties, as it is considered an inevitable outcome of curing.
Repair Solution:
- If Within Warranty Period: Contact serviceQ to assess if the settlement-related cracks are eligible for warranty repair.
- If Outside Warranty: Use an epoxy concrete crack filler to repair minor cracks or hire a certified trade for professional resurfacing.
2. Spalling (Surface Flaking or Peeling)
Warrantability:
- 1-Year Builder’s Warranty: Surface spalling due to improper finishing or curing can be covered if it covers more than 10% of the surface per panel
- Damage from de-icing salts or neglect is excluded.
Repair Solution:
- If Within Warranty Period: Contact serviceQ to assess the issue and arrange for a qualified concrete trade if required.
- If Outside Warranty: Hire a professional to resurface or overlay the affected concrete.
3. Larger Structural Cracks
Warrantability:
- Large cracks along the control joints or along the edges of a concrete pad are usually not covered as they are often caused by excessive weight (vehicles, machinery). Physical damage is not covered under warranty.
Repair Solution:
- If Within Warranty Period: Report the issue to serviceQ for evaluation.
- If Outside Warranty: Contact a certified trade to replace or stabilize the damaged concrete.
4. Settling or Sinking
Warrantability:
- 1-Year Builder’s Warranty: settling or sinking due to improper installation or preparation may be covered under the materials and workmanship warranty for one year.
- Settlement is generally not covered under warranty as it is considered a natural occurrence in new construction areas.
Repair Solution:
- If Within Warranty Period: Notify serviceQ and arrange an inspection to confirm eligibility for warranty repair.
- If Outside Warranty: Hire a certified concrete contractor for mudjacking, foam lifting, or slab replacement.
5. Discoloration or Stains
Warrantability:
- Discoloration is generally excluded from warranty coverage unless explicitly caused by improper curing or finishing.
Repair Solution:
- If Within Warranty Period: Inform serviceQ if discoloration can be linked to a workmanship defect.
- If Outside Warranty: Pressure wash with a concrete-safe cleaner or consult a professional for acid-wash treatment or staining.
6. Cracked or Uneven Garage Pad
Warrantability:
- Typically, not covered unless cracks are over 2mm wide or affect structural integrity and drainage.
Repair Solution:
- If within warranty: Reach out to serviceQ to assess any structural or installation defects potentially covered.
- If outside warranty: Call a certified contractor to repair cracks using concrete fillers or relevel low areas caused by uneven flooring.
