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
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
- Joint edge spalling
- Surface cracking and breakage
- Slab deterioration
- Increased maintenance costs
- Trip hazards and operational risk
Timing Expertise
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 control joint sealing
to maintain waterproof integrity and long-term durability.

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.

FREQUENTLY ASKED QUESTIONS?
How long does control joint sealing last?
Can saw cut joint sealing handle heavy traffic areas?
Why is timing critical for saw cut joint sealing?
Proper timing ensures optimal adhesion, flexibility, and long-term performance of the saw cut joint sealing system.
What standards apply to saw cut joint sealing?
Saw cut joint sealing typically follows standards such as ASTM C920 and ASTM C1193, along with local construction standards.
What is saw cut joint sealing?
What is saw cut joint sealing?
Saw cut joint sealing is the process of filling and sealing joints created by saw cutting concrete to control cracking and protect the slab.
Why is saw cut joint sealing important?
Saw cut joint sealing prevents water, debris, and chemicals from entering the joint, helping to maintain the durability of the concrete.
When should control joint sealing be completed in new construction?
Is a control joint the same as an expansion joint?
Not quite. A control joint is a saw-cut or grooved line that “controls” where concrete cracks as it shrinks. An expansion joint goes all the way through the slab to allow for thermal movement. Both require sealing.
