AFS Rediwall increases installation speed, structural durability, and NCC compliance, only if installed correctly. In many projects, installation mistakes decrease accuracy, delay inspections, or breach AS3600 guidelines.
At Murs Projects, we’ve seen firsthand how errors like misaligned base tracks, under-bracing, and improper concrete core filling can impact project timelines and inspection outcomes. That’s why we’ve prepared this guide to help you avoid the most common pitfalls and deliver clean, compliant walls every time.
Whether you're a site foreman, contractor, or builder, this checklist of field-tested mistakes and how to prevent them will help you save costs, protect quality, and keep your Rediwall installations up to spec.
Mistake 1: Misaligned Base Tracks
Misaligned base tracks cause panel skewing, joint gaps, and vertical deviation across wall height. This structural walls failure begins when tracks are not correctly positioned or anchored.
If you're unfamiliar with how AFS Rediwall functions structurally, refer to our AFS Rediwall Guide which explains its core components, uses, and typical applications on-site.
Common causes:
Installing tracks over slab edge
Uneven grid measurements
No laser alignment or grid check
How to avoid:
Set tracks 30 mm from slab edge
Use laser or string to verify alignment
Anchor at 300 mm centers
Keep deviation under ±5 mm across wall
Tip: Misaligned tracks affect interlocking, core fill flow, and bracing geometry.
Mistake 2: Inadequate Bracing or Missed Prop Points
Insufficient bracing causes wall bowing, shifting, or blowouts during concrete filling. These failures increase cost and risk during structural inspection.
Common causes:
Braces too far apart
Props unsecured at base or top
Missing mid-height props on tall walls
How to avoid:
Use props every 1.5–2 m or per engineer spec
Clamp braces at slab and panel face
Verify verticality using plumb bob or laser
Retension before concrete pouring
Reminder: Bracing maintains vertical position and resists concrete pressure.
Mistake 3: Overfilling Concrete Without Lift Breaks
Overfilling Rediwall cavities increases hydrostatic pressure, causing joint splits, bulging, or blowouts. Lift-based pours reduce stress and allow consolidation.
Common causes:
Single-lift continuous pours
Wet mix or uncontrolled slump
Skipped lift breaks
Poor vibration
How to avoid:
Pour in 1.2–1.5 m lifts
Pause 10–30 minutes between stages
Use 50 mm flexible hose to fill
Vibrate each lift with 25–35 mm head
Note: Overfilling never saves time. It creates structural and compliance risks.
If you're not confident managing the core fill process, it helps to have experienced people on-site. Our team of AFS Rediwall installers in Sydney has handled hundreds of pours, we know exactly how to stage each lift to avoid blowouts and meet engineering specs. Call us now at 0420 203 076
Mistake 4: Improper Rebar Sizing or Spacing
Incorrect rebar size or layout reduces load capacity and breaches AS3600 compliance. Every misstep weakens structural continuity.
Common causes:
Using N12 bars instead of N16
No lap length or anchorage
Missing ties or ligatures
No spacers = poor concrete cover
How to avoid:
Follow structural drawings exactly
Use plastic chairs/spacers for cover
Tie horizontal ligatures every 400–600 mm
Align vertical bars with starters before pour
Tip: Poor steel fixing leads to concrete shifting rebar during vibration.
Mistake 5: Poor Panel Join Handling
Improper joins at corners or end caps cause leaks, joint movement, or visual defects. Junctions are critical for watertight and structurally sound walls.
Common causes:
No corner or T-joiners
Poor cuts around openings
No PVC adhesive sealing
Open ends without caps
How to avoid:
Use AFS factory corner joiners and T-pieces
Trim with fine-tooth saw only
Seal with PVC adhesive
Install caps at all terminations
Reminder: Join integrity determines visual quality and concrete containment.
Mistake 6: Ignoring QA and Compliance Checks
Skipping QA checks results in rework, compliance delays, or failed inspections. Quality control ensures build accuracy and documentation for council sign-off.
Common causes:
No check for wall plumb or square
Ignoring brace spacing
No log of steel placement or joins
No photo evidence or pre-pour review
How to avoid:
Assign foreman or QA officer
Capture photos before core fill
Verify all tolerances and measurements
Tip: Documentation protects against disputes, delays, and warranty issues.
Mistake 7: Removing Braces Too Early or Skipping Post-Pour Care
Removing braces too early risks misalignment or bowing. Ignoring post-pour care affects appearance and structural durability.
Common causes:
Removing props before cure
Not cleaning laitance or splatter
Ignoring joint movement or leaks
Skipping top caps or connectors
How to avoid:
Leave props 24–48 hours depending on mix and weather
Clean panels with sponge immediately
Inspect for leaks or defects
Install top caps or slab connectors as designed
Reminder: Post-pour is your last QA stage before the structure is locked in.
How to Avoid These AFS Rediwall Mistakes?
Avoid Rediwall mistakes by following a verified step-by-step build process. Sequencing and control reduce rework, cost, and compliance risk.
Builder’s Checklist:
Align base tracks 30 mm back from slab edge
Brace every 1.5–2 m + mid-height for tall walls
Pour in 1.2–1.5 m lifts, pause 10–30 minutes
Use correct rebar (N12/N16), lap, and spacers
Install corner/T joiners, seal with adhesive
Log QA checks before and after pour
Leave braces 24–48 hrs and clean panel face

Frequently Asked Questions
What is the most common AFS Rediwall installation mistake?
Misaligned base tracks are the most common mistake. They cause skewed panels, joint gaps, and vertical drift.
How do I brace AFS Rediwall properly?
Install props every 1.5–2 m. Clamp each to the slab and panel face. Add mid-height braces above 3.3 m.
What happens if I overfill concrete in one pour?
Overfilling increases hydrostatic pressure. It risks panel deformation, joint failure, or blowouts. Use controlled lifts.
Can I use any rebar size inside AFS Rediwall?
No. Follow engineering specifications. Usually N12 or N16 with correct lap, cover, and ties.
Is it okay to remove braces the next morning?
It depends on curing time and temperature. Best practice: leave braces for 24-48 hours.
