Question 1

How long does structural remediation take?

Accepted Answer

Project duration depends on scope: crack injection 1-2 days, concrete cutting 1-3 days, structural alterations 5-10 days, and full building remediation 2-8 weeks. We provide detailed timelines in our quotes and maintain strict project schedules to minimize disruption. Most residential repairs complete within 1 week.

Question 2

Will work disrupt my business or residence?

Accepted Answer

We minimize disruption through careful planning, dust control systems, noise reduction, and flexible scheduling including after-hours work. For commercial projects, we coordinate around business hours. Concrete cutting uses water suppression for dust-free operation. Most crack injection and scanning work causes minimal disruption.

Question 3

What equipment and materials do you use?

Accepted Answer

We use professional-grade equipment: Hilti diamond saws for cutting, Desoi/Hilti injection pumps, Hilti GPR scanners for slab scanning, and Building Commissioner-approved epoxy resins (Sika, BASF) and grouts. All materials meet Australian Standards AS 3600/AS 3958 for structural concrete repair.

Question 4

What warranty do you offer on repairs?

Accepted Answer

We provide 5-10 year warranties on structural crack injection (epoxy), 3-5 years on waterproofing injection (polyurethane), and 2-5 years on concrete cutting/patching depending on application. All work is Building Commissioner-approved and complies with Australian Standards. Warranties cover materials and workmanship.

Question 5

Are you fully licensed and insured?

Accepted Answer

Yes, TRD Remedial holds Building Commissioner approval for structural remediation, $20 million public liability insurance, workers compensation insurance, and all required NSW building licenses. Our team is qualified in working at heights, confined spaces, and adheres to strict OH&S protocols on every job.

Question 6

When do you use epoxy vs polyurethane injection?

Accepted Answer

Epoxy injection is used for structural crack repair where strength restoration is critical - it bonds concrete together and can restore 100% structural capacity. Polyurethane injection is used for waterproofing active leaks as it expands and forms flexible seals. We assess each crack and recommend the appropriate material based on structural requirements.

Question 7

What causes concrete cracks?

Accepted Answer

Common causes include: structural overload, settlement/foundation movement, shrinkage during curing, thermal expansion/contraction, corrosion of reinforcement steel, freeze-thaw cycles, and poor initial construction. We identify root causes during inspection to prevent recurrence and recommend appropriate remediation methods.

Question 8

How deep can slab scanning detect?

Accepted Answer

Our GPR (Ground Penetrating Radar) scanning equipment can detect rebar, post-tension cables, conduits, and voids up to 400mm depth in concrete slabs with 99.9% accuracy. We provide on-site marking of findings and detailed scan reports. Essential before any cutting or coring to prevent costly damage to embedded services.

Question 9

How does carbon fibre strengthening work?

Accepted Answer

Carbon Fibre Reinforced Polymer (CFRP) wrapping/plating bonds high-strength carbon fibres to concrete using structural epoxy adhesive. It increases load capacity by 50-200% while adding minimal weight. Ideal for columns, beams, and slabs requiring strength upgrades without increasing dimensions. Provides superior corrosion resistance compared to steel plate bonding.

Question 10

Do you offer emergency services?

Accepted Answer

Yes, TRD Remedial provides 24/7 emergency response for critical structural issues, active water leaks, dangerous spalling, and urgent concrete cutting requirements. Call 0414 727 167 for immediate dispatch. Our emergency team can respond within 2-4 hours across Sydney metro and provide temporary stabilization before permanent repairs.

Question 11

What areas do you service?

Accepted Answer

We service all Sydney metropolitan areas: CBD, Eastern Suburbs, Northern Beaches, North Shore, Inner West, Western Sydney, South Sydney, Hills District, and Sutherland Shire. We also travel to Central Coast, Newcastle, Wollongong, and regional NSW for large commercial projects. Contact us for availability in your area.

Question 12

Do you handle both commercial and residential projects?

Accepted Answer

Yes, we service residential homes, commercial buildings, high-rise towers, warehouses, carparks, and infrastructure projects. Our team scales from small crack repairs to multi-million dollar structural remediation projects. Recent projects include Barangaroo towers, Sydney Metro, and 500+ residential repairs.

Question 13

Do you offer ongoing maintenance contracts?

Accepted Answer

Yes, we provide annual/bi-annual maintenance contracts for commercial buildings, strata complexes, and industrial facilities. Services include crack monitoring, sealant replacement, concrete patching, and preventative inspections. Maintenance contracts include priority scheduling, discounted rates, and detailed reporting for building managers.
