Let’s delve into the problems that can arise with concrete patios and discover the best ways to tackle them.

Problems and Remedies

Following are the common problems and their remedies that can be undertaken by the homeowners for the upkeep of their patios made of polished concrete in Geelong.

  1. Cracking

One of the most common issues with concrete patios is cracking. Cracks occur due to various reasons, including these –

  1. Settlement: Uneven settling of the ground beneath the patio can lead to cracks in the concrete. This can happen due to improper soil preparation, weak subgrade, or inadequate compaction during installation. 
  2. Shrinkage: Not installing proper control joints during the construction can cause concrete to shrink as it cures, which results in cracks.
  3. Freeze-thaw cycles: In regions with cold climates, moisture can penetrate the concrete and freeze during winter. The frozen water expands and causes cracks. 
  4. Overloading: Placing heavy objects, such as large furniture or equipment, on the patio can exceed its load-bearing capacity, leading to cracking.


It is crucial to address the underlying causes to mitigate cracking issues –

  1. Proper site preparation: Ensuring proper soil compaction, appropriate subgrade materials, and adequate drainage can minimise settlement-related cracking. 
  2. Control joints: Installing control joints at regular intervals allows the concrete to expand and contract without developing significant cracks. 
  3. Reinforcement: Adding steel reinforcement, such as rebar or wire mesh, can enhance the patio’s structural integrity and minimise cracking. 
  4. Sealing: The application of a high-quality concrete sealer can help reduce moisture penetration and protect the patio from freeze-thaw damage.

2. Spalling

Spalling refers to the flaking, chipping, or peeling of the surface of polished concrete in Geelong. Common causes of spalling include –

  1. Poor installation: Inadequate mixing, sufficient curing time, or improper finishing techniques during construction can result in solid surface layers prone to spalling. 
  2. Freeze-thaw cycles: As mentioned earlier, freezing and thawing water within the concrete can cause spalling over time. 
  3. Chemical exposure: Certain chemicals, such as de-icing salts or harsh cleaning agents, can lead to surface deterioration and spalling. 
  4. Moisture infiltration: If water infiltrates the concrete, it can weaken the bond between the surface and underlying layers, causing spalling. 


To prevent and address spalling –

  1. Quality construction practices: Employ experienced contractors who follow proper mixing, curing, and finishing techniques during installation. 
  2. Proper drainage: Ensuring patio designs with appropriate slopes and drainage systems to minimise water accumulation.
  3. Sealers and coatings: Applying a suitable concrete sealer or polishing in Geelong can protect the surface from moisture and chemical damage. 
  4. Avoid harsh chemicals: Use mild cleaning agents when maintaining the patio, and avoid de-icing salts or other chemicals that can harm the concrete.

3. Scaling

Scaling refers to the flaking or peeling of the surface layer of the polished concrete in Geelong, similar to spalling. However, scaling typically occurs due to different factors –

  1. Poor curing: Insufficient or improper curing methods during the initial stages of concrete placement can weaken the surface layer, leading to scaling. 
  2. Overworking the surface: Excessive troweling or finishing can result in a weak surface prone to scaling. 
  3. Freeze-thaw cycles: Like spalling, repeated freeze-thaw cycles can cause scaling, particularly when the concrete has low air entrainment.


To prevent and address scaling issues –

  1. Proper curing: Follow recommended methods, such as keeping the concrete moist and protected during the initial curing period. 
  2. Control troweling: Limit the process to achieve the desired finish without overworking the surface.
  3. Air entrainment: Ensure that the concrete mix has appropriate air entrainment additives to enhance its resistance to freeze-thaw cycles. 
  4. Avoid de-icing salts: Refrain from using them on the patio, as they can accelerate scaling and other forms of surface deterioration.

4. Stains and Discoloration

Concrete patios are susceptible to stains and discoloration caused by various sources –

  1. Organic stains: Leaves, grass, food spills, or other organic materials can leave unsightly stains on the concrete surface. 
  2. Oil and grease: Vehicle leaks, grilling accidents, or machinery can introduce oil and grease stains that are difficult to remove. 
  3. Efflorescence: Efflorescence occurs when soluble salts in the concrete migrate to the surface, leaving behind white, powdery deposits. 
  4. Rust and metal stains: Patio furniture, metal accents, or rusting rebar can create rust stains on the concrete.


To mitigate staining and discoloration –

  1. Prompt cleaning: Regularly sweep or rinse off organic materials, and clean stains promptly to prevent them from penetrating the surface. 
  2. Seal the concrete: A high-quality concrete sealer can create a protective barrier, making cleaning easier and preventing stains from penetrating. 
  3. Use absorbent materials: Place mats or rugs under grills, furniture, or other potential stain-causing sources to minimise direct contact with the concrete. 
  4. Proper drainage: Ensure the patio has adequate drainage to prevent water pooling, which can contribute to efflorescence formation.

By employing proper construction practices, implementing maintenance routines, and considering protective measures like sealing and drainage, homeowners can ensure the longevity and functionality of their patios made of polished concrete in Geelong. Regular inspections, maintenance, and timely repairs will help homeowners enjoy their outdoor spaces for years.
