8 Common Concrete Problems and Their Solutions in Perth

Concrete is one of the most widely used construction materials in Perth due to its strength, durability, and long lifespan. However, even the best-laid concrete is not immune to wear and damage over time. From weather conditions to soil movement, several factors can lead to deterioration.

If you are dealing with concrete repair Perth, understanding the most common issues and their solutions can help you take early action and avoid costly repairs.

At Allduro, we specialise in professional concrete solutions designed to restore strength, safety, and appearance to all types of surfaces.


1. Cracking in Concrete

Cracks are the most common issue in residential and commercial concrete. They can appear as hairline fractures or deep structural breaks.

Causes:

  • Shrinkage during curing
  • Soil movement beneath slabs
  • Temperature changes
  • Excess load or poor installation

Solution:
Small cracks can be sealed using epoxy or flexible sealants, while larger structural cracks may require injection repair or partial slab replacement.

Early concrete repair Perth services help prevent cracks from spreading and weakening the structure.

2. Concrete Spalling (Surface Flaking)

Spalling occurs when the surface layer of concrete starts breaking away, exposing rough and uneven patches.

Causes:

  • Moisture penetration
  • Reinforcement steel corrosion
  • Poor finishing or curing

Solution:
Damaged areas are removed and resurfaced using polymer-modified repair mortar or protective overlays. Sealing the surface prevents future moisture damage.

3. Concrete Settlement and Sinking

Uneven or sunken slabs are a major safety and structural concern.

Causes:

  • Poor soil compaction
  • Water erosion beneath slabs
  • Natural ground movement

Solution:
Techniques like slab lifting (mudjacking or foam injection) restore the surface level without full replacement.

4. Concrete Cancer (Rebar Corrosion)

One of the most serious issues in concrete structures is internal steel reinforcement corrosion.

Causes:

  • Water and salt penetration
  • Cracks exposing steel reinforcement
  • Coastal environmental conditions

Solution:
Damaged concrete is removed, steel is treated or replaced, and the area is rebuilt and sealed. Preventative coatings help stop future corrosion.

5. Surface Erosion and Wear

Over time, concrete surfaces can become rough, dusty, or worn out due to heavy traffic and exposure.

Causes:

  • Weather exposure
  • Poor mix quality
  • Abrasion from vehicles and foot traffic

Solution:
Resurfacing with protective coatings or polishing restores durability and improves appearance.

6. Discoloration and Staining

Concrete can lose its original look due to stains or uneven colouring.

Causes:

  • Oil spills and chemical exposure
  • Water pooling
  • Sun and UV exposure

Solution:
Pressure cleaning, chemical treatment, and resealing restore a clean and uniform finish.

7. Uneven or Poor Drainage Slabs

Poor drainage can lead to water pooling, which accelerates concrete damage.

Causes:

  • Incorrect slope design
  • Ground shifting
  • Blocked drainage systems

Solution:
Regrading or resurfacing the slab ensures proper water flow and prevents long-term deterioration.

8. Delamination (Layer Separation)

Delamination occurs when the top layer of concrete separates from the base.

Causes:

  • Improper finishing techniques
  • Air or water trapped during pouring
  • Freeze-thaw or moisture pressure

Solution:
Affected layers are removed and replaced with properly bonded resurfacing materials.
