As 2025 draws to a close, it’s time to inspect and maintain your pre-cast concrete structures. Cobro Concrete has created a maintenance for pre-cast concrete checklist to make the process easier.

Maintenance for Pre-cast Concrete Checklist

Your year-end pre-cast concrete maintenance should focus on four key action areas: inspection, cleaning, repairs, and landscape management.

Remember to follow manufacturer guidelines at all times. They Follow this expert checklist:

1. Inspection and Assessment

  • Visual assessment: Start by conducting a ground-level visual assessment of all concrete surfaces and joints.
  • Actively look for damage: After a general assessment, look closely at all parts of the structure for any cracks, chips, spalling, or discolouration.
  • Checks joints and sealants: Turn your attention to all joints and check for signs of deterioration, cracking, or peeling.
  • Assess drainage systems: Check all gutters, downspouts, and drainage channels in, on, or around the structure to ensure that they are all diverting water away properly.
  • Document findings: Record all your findings so you can track the condition of the structure over time and prioritize repairs.

2. Cleaning and Preparation

  • Wash all surfaces with a pressure washer, mild detergent and a soft-bristled brush.
  • Remove any stains with the appropriate cleaning materials. Refer to the manufacturer’s guidelines and recommendations for maintaining your specific precast concrete. They may provide additional instructions or specific products to use for cleaning and maintenance, ensuring the best care for your concrete structures.
  • Clear away any debris such as leaves, dirt, silt or vegetation.

3. Repairs and Protection

  • Repair cracks: Use a patching compound to fill small cracks and chips.
  • Reapply sealants: If the sealants are showing signs of wear, re-seal joints wherever applicable.

4. Landscape Maintenance

  • Trim vegetation: If there is any plant growth over your pre-cast concrete structures, trim it back. Overgrowth could potentially damage the structures.
  • Check root systems: Look deeper than just overgrowth. Inspect the root systems of any shrubs or trees nearby, as these can impact the stability of the structure and do serious, irreversible damage if left unattended.
