Hydro Demolition

Aqua Prep, Australia’s leading hydro demolition specialist, utilizes ultra-high-pressure water (up to 45,000 psi) for precise concrete removal while preserving underlying structures. This innovative method aligns with Australian workplace health and safety standards and offers significant advantages over traditional demolition techniques.

In terms of compliance, hydro demolition adheres to the Work Health and Safety (WHS) Act and Regulations, helping employers fulfill their duty to eliminate or minimize risks to worker health and safety. It also meets Safe Work Australia’s exposure standard for respirable crystalline silica, set at 0.05 mg/m³ over an 8-hour time-weighted average. Furthermore, the technique follows AS 2670 by significantly reducing vibration exposure compared to conventional methods like jackhammering.

Importantly, Aqua Prep’s hydro demolition practices comply with two key Australian water jetting standards:

1. AS/NZS 4233.1:2013 – High pressure water jetting systems – Safe operation and maintenance: This standard provides guidelines for the safe operation and maintenance of high-pressure water jetting equipment, ensuring that Aqua Prep’s operations meet stringent safety requirements.
2. AS/NZS 4233.2:2013 – High pressure water jetting systems – Construction and performance: This standard specifies the construction and performance requirements for high-pressure water jetting equipment, guaranteeing that Aqua Prep’s machinery is built and operates to the highest industry standards.

Safety is a paramount benefit of hydro demolition. It reduces workplace hazards by 40% through remote operation capabilities, allowing workers to maintain a safe distance from potentially dangerous areas. This approach minimizes operator fatigue and the risk of injuries associated with vibration and repetitive motion, which are common issues with traditional demolition methods.

Precision and quality set hydro demolition apart from other techniques. It offers pinpoint accuracy for selective concrete removal, crucial for projects like bridge deck rehabilitation or partial structure removal. Unlike jackhammers and mulchers, hydro demolition eliminates the risk of micro-fractures in the remaining concrete structure, ensuring long-term stability and preserving the integrity of both the concrete and rebar.

By choosing hydro demolition that adheres to these Australian standards, construction and infrastructure projects can achieve superior results while prioritizing worker safety and regulatory compliance. Aqua Prep’s commitment to following these standards ensures that their hydro demolition services meet the highest levels of safety, efficiency, and quality in the Australian construction industry.
