Water penetration testing services in Auckland

Water penetration testing is a common practice used to evaluate the ability of a building’s exterior to resist water infiltration. Water penetration testing involves the controlled application of water to a building’s exterior, such as the roof, walls, windows, and doors, in order to simulate rain or other water events.

Water penetration testing aims to identify potential areas of water intrusion, which can lead to moisture problems, mould growth, and structural damage if left unchecked. The testing can be performed using a variety of methods, such as the ASTM E1105 standard or the AAMA 501.2 standard, and typically involves visual inspections, water pressure testing, and other diagnostic techniques.

Water penetration testing is typically performed by experienced professionals, such as building inspectors or certified waterproofing contractors, who are trained to identify areas of potential water intrusion and recommend appropriate corrective measures. By identifying and addressing potential water intrusion issues, building owners can help protect their investment and ensure the long-term durability and performance of their building.

Water penetration testing can offer several advantages for building owners and occupants

Identification of potential water intrusion issues: Water penetration testing can help identify areas of a building’s exterior that are vulnerable to water intrusion, such as leaks around windows, doors, roofs, or other building penetrations. By identifying these potential issues, building owners can take corrective action to prevent water infiltration, which can lead to costly repairs and long-term damage to the building.

Water Penetration Testing Advantages

This test can can also bring many benefits to owners who are interested in detecting intrusion issues 

Water penetration testing (WPT) can help improve a building’s overall performance by identifying and addressing issues that can compromise the integrity of the building envelope. By preventing water intrusion, building owners can help protect the building’s structural integrity, reduce the risk of mould growth and other moisture-related problems, and maintain a comfortable and healthy indoor environment.
Water penetration testing is a proactive and preventive measure that contributes significantly to a building’s overall performance, durability, and longevity. By addressing weathertightness issues early on, the testing process supports a building’s ability to withstand environmental challenges and provides a basis for continuous improvement in construction practices.

Many building codes and standards require water penetration testing as part of the building envelope commissioning process. By performing water penetration testing, building owners can ensure compliance with local building codes and standards, and avoid potential legal or regulatory issues.

The New Zealand Building Code has specific requirements related to weather tightness to prevent water ingress into buildings. Historically, issues related to water penetration and building weather tightness led to changes in the Building Code, particularly in the wake of the “leaky building crisis” in New Zealand.

The Building Code clause that addresses weathertightness is E2 – External Moisture. This clause outlines the performance standards and requirements related to the prevention of external moisture (including water penetration) in buildings. The code focuses on elements such as cladding systems, flashings, and detailing to ensure that buildings are weathertight.

While the Building Code does not explicitly require a specific testing method like water penetration testing, it emphasises achieving the required performance standards for weather tightness. The methods used to demonstrate compliance may include testing, product certification, and adherence to approved building practices.

Professionals in the construction industry, including architects, builders, and building surveyors, play a crucial role in ensuring that buildings comply with the weather tightness requirements outlined in the Building Code. We recommend you reach out to Rommel today to discuss the various methods we use for onsite water testing to aid in verifying compliance.

While the impact of water tightness testing on property value may vary, it is generally viewed as a positive factor in building maintenance and quality assurance. Architects, designers and builders for new builds, and then property owners and sellers for existing buildings should consider the long-term benefits of such testing regarding property value, marketability, and overall satisfaction for future or current occupants.

By ensuring that a building is water-tight and performing at optimal levels, water penetration testing can help increase the property value and marketability of a building.
