Pre-Cast for Exterior
Pre-cast concrete is a durable and versatile construction material manufactured off-site and used for building exteriors, such as walls, cladding, façades, and decorative elements. These products are designed for long-term use in various environmental conditions. Pre-cast offers excellent structural integrity and aesthetic flexibility, making it a popular choice for both residential and commercial spaces.
Warrantability
Alberta New Home Warranty Standards:
- 1-Year Warranty: Pre-cast steps 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 typically provide a one-year warranty covering installation defects or issues related to workmanship.
Manufacturer’s Warranty:
- Manufacturer warranties for pre-cast materials vary but often cover structural defects, cracks, or material failure caused by manufacturing errors. These warranties are typically valid for a period of 1-5 years, covering the structural integrity of the steps themselves.
Maintenance
Cleaning
- Regularly clean pre-cast surfaces with mild detergents and water to prevent the buildup of dirt, algae, and stains.
Inspection
- Conduct seasonal inspections for visible cracks, erosion, or staining caused by contaminants like mold or rust.
Sealant Management
- If sealants or finishes are applied to the precast, check periodically and reapply protective coatings as recommended (usually every 5–10 years).
What to Avoid:
- Abrasive scrubbers or high-pressure washing, which can compromise the integrity of the surface.
- De-icing chemicals, particularly with high salt content, which can cause long-term deterioration.
Common Issues, Warrantability, and Repair Solutions
1. Cracking
Warrantability:
- 1-Year Builder’s Warranty: Builders may provide coverage for a limited duration if the cracks result from poor installation or workmanship.
- Manufacturer’s Warranty (Varies): Cracking in pre-cast concrete may be covered under the manufacturer’s warranty if the damage is deemed to be caused by defects in materials or manufacturing. Surface cracks caused by external factors, such as weather or improper installation, are generally not covered.
Repair Solution:
- If Within Warranty: Contact serviceQ to assess and repair warrantable damage.
- If Outside Warranty: For hairline cracks or non-structural surface cracks: Use a concrete repair filler or an epoxy-based crack filler. Clean the area, ensure it is dry, and then apply the filler according to the manufacturer’s instructions. Smooth the surface and let it cure completely. For more significant structural cracks: Contact a certified trade for professional repairs.
2. Surface Staining
Warrantability:
- Surface staining caused by environmental factors like dirt, water, mildew, or rust is generally not covered under warranties, as these are considered maintenance-related issues.
Repair Solution:
- If Within Warranty: Contact serviceQ for assistance in discussing DIY repairs for this non-warrantable issue.
- If Outside Warranty: Use a concrete-specific cleaner to tackle stains. For tough stains, such as rust, use an acidic rust remover designed for concrete applications. Apply the cleaner, scrub with a soft bristle brush, and rinse thoroughly. To prevent recurring stains, consider applying a high-quality concrete sealant to protect the surface. This sealant should be reapplied every 5–10 years.
3. Erosion
Warrantability:
- Erosion of pre-cast surfaces due to natural weathering or chemical exposure is usually not covered under warranties, as durability is considered a maintenance responsibility (e.g., regular sealant reapplication and avoiding harmful chemicals).
- Manufacturer’s Warranty (Varies): Material defects causing pre-cast erosion may be covered if due to a material defect.
Repair Solution:
- If Within Warranty: Contact serviceQ for further guidance and assessment.
- If Outside Warranty: Minor erosion: Use a concrete patching mix or resurfacer to restore the affected area. Clean the surface thoroughly, apply the patching compound, and smooth it out for a seamless finish. Severe erosion or pitting: Engage professional trades for repair and resealing services.
4. Warping or Deformation
Warrantability:
- 1-Year Builder’s Warranty: Issues related to installation, soil movement, or uneven load distribution may be covered under the builder’s warranty if they are discovered and reported within the first year.
- Manufacturer’s Warranty (Varies): Warping or deformation of pre-cast concrete may be covered under the manufacturer’s warranty if caused by defects in material composition or improper curing.
Repair Solution:
- If Within Warranty: Contact serviceQ for assistance.
- If Outside Warranty: Hire a certified trade professional for assessment and repairs.
