SEALTECH INDUSTRIES
Control Joint Filling and Saw-Cut Joint Sealing
We specialise in precision Control Joint Filling and Saw-Cut Joint Sealing, utilising advanced elastomer compounds that support joint edges under load while maintaining the flexibility needed for natural concrete movement. Keep your operations smooth, safe, and compliant with a structurally sound floor.
Service Area: Control Joint Sealing for South-East Queensland and Northern NSW
(Brisbane, Gold Coast, Ipswich, Moreton Bay, Redland City and surrounding regions)
Commercial Control Joint Filling and sealing 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 horizontal or vertical control joints must be professionally filled to protect slab edges from impact damage, load stress and premature deterioration.
SealTech Industries delivers specialist control joint filling and sealing 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 horizontal and vertical control joint systems are designed to withstand high-load traffic including forklifts, pallet movers and heavy vehicle access.
Standards & Specification Compliance
All concrete wall control joints sealing 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 control joint sealing specialist 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 control joint filling 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 control joint filling installation, repeated traffic leads to:
- Joint edge spalling
- Surface cracking and breakage
- Slab deterioration
- Increased maintenance costs
- Trip hazards and operational risk
Timing Expertise
For existing slabs, control joint filling for concrete 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
professional control joint sealant installation to maintain waterproof integrity and ensure 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. Filling control joints in concrete slabs reinforces these edges, preventing progressive chipping and structural degradation.
Supporting Long-Term Slab Performance
While filling concrete control joints are not waterproofing systems, professional joint 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 concrete wall control joint 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.
our projects
All control joints in concrete walls and floors have been filled and sealed in accordance with project documentation,
manufacturer technical data sheets, and the relevant Australian Standards.

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.
Is concrete control joint filling the same as joint sealing?
Concrete control joint filling and joint sealing are closely related, but they are not always the same.
Joint filling in concrete wall and floor are commonly used in concrete floors to support and protect the joint edges from chipping, spalling, debris build-up, and damage caused by traffic.
Joint sealing in concrete wall and floor focuses more on preventing water, dirt, and contaminants from entering the joint while allowing for movement.
Why should I hire a professional caulker for horizontal control joints?
Horizontal control joints require a specialised approach to ensure a lifetime seal:
Correct Joint Geometry: Pros install a closed-cell backing rod at a precise depth to ensure the sealant only sticks to the top and bottom faces (two-sided adhesion), allowing it to stretch like a rubber band.
Commercial-Grade Materials: Access to industrial polyurethanes and hybrid sealants specified to meet strict Australian Standards for structural movement.
Flawless Aesthetics: Clean, uniform, and tooled lines that preserve your property’s street appeal and structural integrity.
Protect Your Asset: Don’t wait for a heavy storm to find out your control joints have failed. Contact our team today for a professional joint inspection and a durable, compliant caulking solution.

What type of sealant is used for vertical control joints in concrete walls?
The type of sealant used for vertical control joints in concrete wall depends on the project requirements, joint movement, exposure conditions, and substrate type.
Common options include polyurethane, silicone, hybrid, or other elastomeric sealants.
