SEALTECH INDUSTRIES

Control Joint Filling and Saw-Cut Joint Sealing

Industrial Slab Edge Protection for Commercial & Civil Projects

Service Area: South-East Queensland and Northern NSW
(Brisbane, Gold Coast, Ipswich, Moreton Bay,
Redland City and surrounding regions)

Commercial Control Joint Filling Solutions

Concrete is one of the most durable construction materials available. However, as it cures and undergoes natural shrinkage, controlled cracking is inevitable. Saw-cut control joints are intentionally installed to manage this movement and prevent random cracking.

In high-traffic commercial and industrial environments, these joints must be professionally filled to protect slab edges from impact damage, load stress and premature deterioration.

SealTech Industries delivers specialist control joint filling solutions across Brisbane, Gold Coast, Ipswich and Moreton Bay. Our systems are engineered for durability, load tolerance and long-term asset protection in demanding commercial environments.

Why Commercial Clients Choose SealTech Industries?

Commercial-Scale Expertise

We operate exclusively in commercial, industrial and civil environments. Our systems are designed to withstand high-load traffic including forklifts, pallet movers and heavy vehicle access.

Standards & Specification Compliance

All installations are completed in accordance with Australian Standards, issued-for-construction documentation and manufacturer technical data sheets.

Industrial-Grade Materials

We specify semi-rigid polyurea and polyurethane joint fillers (typically Shore A 80–95 hardness range) engineered for load-support applications in Class 1–4 industrial floors.

Rapid Return to Service

Where project conditions permit, we utilise fast-curing systems that allow areas to return to service within hours, minimising operational downtime.

Dust-Controlled Surface Preparation

All preparation works are conducted using diamond grinding and vacuum-shrouded equipment with compliant dust extraction systems in accordance with Queensland WHS silica regulations

Experienced Technical Applicators

Our technicians bring experience across logistics facilities, infrastructure projects, high-rise developments and heavy-use industrial environments.

The Technical Execution: Our 4-Step Process

To ensure long-term performance in Queensland’s climate and operating conditions, our installations follow a disciplined workflow.

Step 1: Joint Preparation & Cleaning

Adhesion is only as strong as the substrate. We utilise specialised joint-cleaning saws and diamond grinding equipment with integrated HEPA-filtered dust extraction to remove laitance, debris and weak concrete from the full depth of the saw cut. This ensures the filler bonds directly to sound concrete.

Step 2: Depth Assessment

For industrial saw-cut control joints, fillers are typically installed to the full depth of the saw cut (commonly 25–40mm) to provide continuous load-support along slab edges. Backer rod is generally not required, as control joints are designed for crack control rather than movement accommodation. Final depth is confirmed in accordance with project specifications and slab design requirements.

Step 3: Precision Material Installation

Using calibrated dual-component pumping or approved dispensing systems, semi-rigid polyurea or polyurethane fillers are installed at the manufacturer’s specified mix ratio to achieve the required hardness and durability rating.

Step 4: Flush Shaving & Finishing

Following initial cure (typically 15–60 minutes depending on system specified), excess material is shaved flush using specialist floor razors. This creates a smooth, level transition across the joint, eliminating impact points for wheeled traffic and ensuring professional presentation.

CONTROL JOINT FILLING EXPLAINED​

Control Joint Filling for Industrial & Commercial Facilities

Industrial floors experience constant stress along joint edges. Without professional filling, repeated traffic leads to:
  • Joint edge spalling
  • Surface cracking and breakage
  • Slab deterioration
  • Increased maintenance costs
  • Trip hazards and operational risk

Timing Expertise

Industrial control joints are typically filled after the slab has completed its primary shrinkage cycle — often between 28–90 days post-placement depending on slab design and loading conditions.

For existing slabs, joint filling should be considered where there is:

  •  Visible joint edge chipping
  •  Missing or deteriorated filler
  •  Dusting or debris accumulation
  •  Uneven floor transitions

A professional assessment determines the correct timing and material selection.

Any structure exposed to structural movement or environmental stress requires professionally installed movement joint sealing
to maintain waterproof integrity and long-term durability.

COMPLIANCES​

Completed in accordance with AS 3600, AS 4654 (where applicable), project specifications and manufacturer technical data sheets.

Where Every Seal Tells the Story

Key Advantages of Professional Control Joint Filling

Preventing Joint Edge Spalling

Unfilled saw-cut joints leave sharp slab edges exposed to impact damage. Professional filling reinforces these edges, preventing progressive chipping and structural degradation.

Supporting Long-Term Slab Performance

While control joints are not waterproofing systems, professional filling helps reduce moisture and contaminant ingress into the slab, supporting long-term durability — particularly in humid and coastal environments such as Brisbane, Gold Coast and Moreton Bay.

Fast, Efficient & Minimal Disruption

Our selected systems are engineered for:
• Rapid cure times
• Minimal operational disruption
• High load tolerance
• Clean, professional finishes
In many cases, operational areas can return to service the same day.

All work is completed in accordance with project documentation, manufacturer technical data and relevant Australian Standards.

FREQUENTLY ASKED QUESTIONS?

How long does control joint sealing last?
High-quality polyurethane and silicone systems typically provide 10–20 years of service life, depending on exposure conditions, movement cycles and maintenance practices.


Most modern commercial and civil structures incorporate movement joints to manage thermal and structural movement. Proper sealing is essential to maintain waterproof integrity and prevent long-term deterioration.

  • Cracked or brittle sealant
  • Adhesion failure at joint edges
  • Visible gaps
  • Water ingress near slabs or façades
  • Rust staining or concrete spalling
    Early intervention prevents costly remediation.
When should joint sealing be completed in new construction?

Movement joint sealing should be completed after concrete curing and surface preparation in accordance with manufacturer guidelines. Premature installation may result in adhesion failure.

Yes. Movement joints should be inspected periodically as part of asset maintenance programs. Proactive resealing significantly extends structural lifespan.
