Crack Repair / Filler Solutions
Cracks can affect durability, safety and long-term performance if they are left open to water ingress, dirt, weeds, loose matter or ongoing movement. Antoun provides concrete crack repair and filler solutions across civil and commercial environments.
Efficient Repair for Demanding Environments
Antoun supports crack repairs across operational sites where the repair needs to be suited to the surrounding structure and site conditions. We can assist with:
- Sealing cracks to reduce water ingress
- Filling cut concrete joints and control joints
- Protecting substrates from further deterioration
- Supporting high-traffic areas exposed to vehicle movements
- Addressing alligator cracking on pavement surfaces
Crack Repair Products
Crack repair is not a one-product job. The right approach depends on crack width, depth, movement, moisture, weather exposure,
traffic load, ponding water, contamination and the condition of the surrounding structure.
Non-Shrink Grout
CEMENT ALL™ Non-Shrink Grout
Suited to strong, stable and durable repairs where a cementitious repair material is needed to fill cracks, repair voids or reinstate affected areas of concrete.
Learn MoreMORTAR MIX™
A mortar-based material suited to concrete surfaces, edges, gaps and localised repairs where a high-strength finish bonded to a prepared concrete substrate is required. This product is well suited to vertical and overhead repairs requiring only potable water for priming.
Learn MoreDPR Kit
FastPatch® DPR Kit
Suited to crack repair on asphalt and road pavement surfaces, including alligator cracking and areas exposed to vehicle traffic.
Learn MoreCrack Filler
FastPatch® Crack Filler
Suited to fast pavement repair on concrete that must be traffic-ready and capable of supporting demanding site conditions. This product is trafficable in <5 min.
Learn MoreAlligator Crack Repair
FastPatch® Alligator Crack Repair
Designed for pavement surfaces affected by alligator cracking. Helps seal and protect cracks across road and high-traffic areas vulnerable to water ingress and ongoing pavement deterioration.

Roads & Motorways
Crack sealing and alligator crack repair help maintain pavement surfaces, reduce water ingress and support safer road conditions before defects develop into potholes or larger pavement failures.
Learn MoreAirport Runways & Aprons
Crack repair on runways, taxiways and aprons involves strict shutdown periods, vehicle traffic, weather constraints and operational demands. Antoun's repair solutions support durable reinstatement without unnecessary downtime.
Learn MoreConcrete Slabs
Concrete slabs can develop cracks from shrinkage, movement, impact, moisture or load demands. Antoun can assist with repair material selection, crack filling and localised slab repairs across industrial and commercial sites.
Bridge Decks
Bridge decks are exposed to traffic, weather and moisture. Crack repair and joint sealing can help protect concrete substrates, limit water ingress and support longer-term durability.
Concrete Delivery
Where crack repair forms part of a larger reinstatement or slab repair program, Antoun's concrete delivery capability supports accurate supply, reduced waste and efficient placement on site.

Antoun’s specialised equipment improves accuracy, reduces manual handling and supports efficient completion where access, timing or tolerance constraints apply.
Why Choose Antoun?
- Proven Remedial Concrete Experience – Since 1979, Antoun has supported industrial, commercial and infrastructure concrete repair and construction projects across Australia and internationally. With more than 30,000m3 replaced for airports, road authorities and asset managers, our team understands how surface condition, site access, traffic demands and material selection affect the outcome of crack sealing and repair works.
- Product Selection Matched to Site Conditions – Some cracks require a tough, flexible seal that accommodates movement. Others need high-strength cementitious repair or mortar-based materials that restore damaged concrete surfaces. Antoun's product range covers the full spectrum of crack repair requirements.
- Site-Ready Equipment and Delivery Capability – As a turn-key solution provider, our specialised equipment supports accurate, efficient repairs in live environments. From onsite batching and concrete delivery to drilling, preparation and finishing, Antoun aligns the repair method with the site's access, program and performance requirements.
What affects crack repair performance?
Surface condition has a direct impact on repair outcomes. Dirt, dust, grease, wet surfaces, loose matter, weeds, moisture and water vapour can all affect bond and durability. Before filling cracks or sealing joints, the surface must be prepared to suit the product and site conditions.
Other factors include:
- Crack width and depth
- Slab thickness
- Joint movement
- Ponding water
- Traffic volumes
- Weather exposure
- Chemical exposure
How Antoun approaches crack repair
Antoun reviews the crack type, substrate, surface condition and site requirements before recommending a repair system. The process may include cleaning, chasing, vacuum preparation, priming, crack filling, flexible sealant installation, mortar repair or reinstatement of the surrounding concrete.
The objective is a repair that suits the substrate, protects against water ingress and performs under the expected traffic and weather conditions.
Frequently Asked Questions
What is the best crack filler product?
The right crack filler products depends on crack type, movement, surface condition and exposure. Antoun provides a range of products that are suitable for all conditions.
Can Antoun’s crack filler products be used on wet surfaces?
Surface preparation remains critical. Dirt, grease, ponding water, loose matter and excess moisture can affect bond and long-term performance. Refer to our Product Matrix to find the best product suited to your project.
What is alligator crack repair?
Alligator crack repair is displayed as cracking across asphalt surfaces. These cracks allow water ingress and can worsen under vehicle traffic if not treated with a suitable repair system.
Does crack sealing stop future cracking?
Crack sealing protects against water ingress and debris but does not remove the cause of ongoing movement. Future cracking depends on the slab, substrate, subgrade, traffic load and joint design.
