The asset of differential pressure testing for roof membrane integrity

Differential pressure testing is a critical procedure in evaluating the integrity of roof membranes. It is used when traditional electronic leak detection of waterproofing membranes is not possible, often as a result of a particular roof construction. This could be due to the membrane being conductive, EPDM for example, or where the substrate is non-conductive, such as timber.

The differential pressure testing process involves applying negative pressure through a Perspex chamber placed on the surface of the waterproofing and monitoring the laps within the chamber for integrity. A surfactant applied to the laps will indicate where a water path is present which can then be marked on the roof surface and repaired by the contractor.

Here are some reasons why differential pressure testing is a valuable asset for waterproofing roof membranes:

1.   Accurate Detection of Leaks: Roof leaks can be challenging to identify because water can penetrate the membrane in one area and travel a considerable distance before showing up inside the building. Differential pressure testing can accurately detect even the smallest of leaks by creating negative air pressure on the outside of the waterproofing membrane and positve air pressure beneath. Any holes, tears, or punctures in the membrane will cause the air to escape, which can then be observed through a perspex chamber.

2.  Cost-Effective: Repairing a leaking roof can be expensive, especially if the problem is not identified early enough. Differential pressure testing can help identify potential problems before they become major issues. This process can save building owners, contractors and roofers considerable expense in repair costs by identifying leaks early and allowing for prompt repair.

3.  Manufacturer Warranties: Many manufaturers require roof membranes to be tested for intergrity by an independent party . Differential pressure testing is an excellent way to meet these requirements and ensure that the roof system is performing as intended.

4.  Verification of Installation Quality: Roof membranes are often installed by a variety of contractors, and their workmanship can vary greatly. Differential pressure testing can help verify that the installation was done correctly, and the roof system is functioning as intended.

5.  Peace of Mind: Roof leaks can be stressful and disruptive to building occupants. Differential pressure testing provides peace of mind by ensuring that the roof system is working correctly and there are no hidden leaks that could cause problems in the future.

The value of electronic leak detection services

 

 

An electronic leak detection service is an invaluable tool for the construction industry, facilities management and the broader property sector, as it provides a non-invasive and highly accurate method of detecting leaks in roofing and waterproofing systems. By utilising advanced electronic equipment, Thornton Consulting’s experienced leak detection operatives are able to pinpoint the exact location of a leak even in hard-to-reach areas, without causing any damage to the underlying structure.

One of the primary benefits of testing waterproofing membranes electronically is the ability to save time and money on repairs. Traditional leak detection methods often require invasive techniques, such as opening up large sections of roofing or waterproofing materials, or other areas of the structure in order to locate the source of the leak. This can result in extensive repair costs and significant downtime for businesses and property owners. Electronic leak detection on the other hand, allows for quick and accurate location of breaches in the roof waterproofing, often with minimal disruption to daily operations. Established in 1986, Thornton Consulting was a pioneer in this technique for clients throughout the UK and Ireland.

Another benefit is its high level of accuracy. By using specialised equipment, leak detection consultants are able to identify breaches in the roof waterproofing membrane with a high degree of precision. This means that repairs can be made quickly and efficiently, reducing the risk of further damage to the structure. This high-tech method also offers a more environmentally-friendly approach to leak detection as it avoids the waste of high volumes of water used in more traditional methods, such as flood testing. 

Electronic leak detection services can provide property owners, businesses, main contractors, Roofers and Architects with peace of mind. By identifying leaks before they become major issues, costly repairs and downtime can be avoided, ensuring the safety and integrity of the structure.

All Thornton Consulting operatives provide a highly professional service in line with the strong company ethics and core values. Their broad and prestigious client base is testament to an outstanding efficiency and competence in the field of leak detection.

Why roof leak detection is beneficial

Roof leak detection is a critical aspect of building maintenance that provides numerous benefits for property owners, construction companies, facilities managers and Architects, plus many others in the construction sector. A roof leak is a significant issue that can cause costly damage to the structure and contents of a building. If not detected and repaired quickly, a small leak can escalate into a major problem that requires expensive repairs and renovations.

Thornton Consulting provide a precise and cost-effective roof leak detection service for clients throughout the UK and the Republic of Ireland, with a highly experienced team of professional operatives and the appliance of advanced technology.

One of the primary benefits of early detection of a breach in the roof membrane is the ability to prevent interior water damage. If left unresolved this can cause substantial damage to the structure of a building and the contents within it, including furniture, vital equipment and electrical systems. By detecting a leak early, the need for costly repairs can be avoided, preventing the development of mould and other harmful microorganisms which can otherwise migrate rapidly.

Another benefit of roof leak detection is that it can help to extend the life of a roof. The roof installation is a considerable investment and by identifying the location of the water ingress and rectifying the problem this can avoid the expense and disruption of having to replace the roof prematurely.

A sound and secure roof also helps to improve energy efficiency. A leaky roof can cause air to escape or cause damage to insulation, leading to an increase in heating and cooling costs. By detecting and repairing leaks, energy consumption can be reduced, with a cost-saving on energy bills and a reduction in the carbon footprint. Roof leaks can also cause electrical systems to short-circuit, creating hazardous conditions for the building’s occupants. With prompt intervention these potential dangers can be avoided, maintaining a safe and healthy environment.

In addition, early isolation and repair can also enhance the overall appeal of a building. Leaks can cause unsightly water damage, staining, and discolouration on the walls and ceilings, which can detract from the aesthetic appearance of the property.

Established in 1986, Thornton Consulting has developed a wide range of testing procedures for a proactive approach in accurately locating leaks in the roof structure which may not easily visible to the naked eye. This is an invaluable service which also avoids the need for time-consuming and costly call-backs after the construction sign-off and provides reassurance that the roof is watertight.

The efficiency of electronic leak detection of waterproofing membranes

 

 

Electronic leak detection is an efficient and accurate method for locating an existing breach in most flat roof waterproofing system. Since the 1980’s Thornton Consulting has been an innovator in this field using both dry and wet electronic leak testing systems as an alternative option to traditional flood testing. Construction companies and architects have increasingly authorised electronic testing to locate and resolve potential breach locations within the roof’s waterproofing material, prior to the final project sign-off. This prevents costly call-backs and delays in the work schedule and ensures the waterproofing is watertight at handover of the roof.

Electronic leak detection is precise and efficient way to integrity test newly installed waterproofing membranes, ensuring even the smallest breaches which may not be visibly apparent can be pinpointed and rectified. This leak detection procedure is non-destructive and the avoidance of wasting high volumes of water also has the advantage of being more beneficial for the environment.

Whilst flood testing is useful in some situations, electronic leak detection is less time consuming and far more accurate at locating breaches when the waterproofing membrane is exposed. In the event that the roof membrane is not compatible with an electronic device, Thornton Consulting can implement alternative testing techniques.

Electronic leak detection is also a commonly used techinique when undertaking building leak investigations. This is an additional service Thornton Consulting provide where the source of water ingress into a building needs to be established. This is particularly useful to owners, managers or operators of buildings such as Hotels, retail centres, industrial units, apartment blocks and schools commonly and office buildings to name but a few. During this diligent survey the water ingress pathways can be identified, enabling any weakness in the waterproofing membrane to be resolved. Visible signs of a leak in the interior of a property may not be immediately apparent underneath the point where the waterproofing material has been breached, or where water is penetrating the strucrure, therefore, the experience of our field technicians and consultants is invaluable in accurately determining the source of a leak.

Thornton Consulting will provide clients with a detailed report once testing has been completed. Specific information relevant to the leak source will be reported in detail, with professional advice regarding remedial actions which are recommended to resolve the leak. Thornton Consulting provide an exemplary electronic leak detection service for Roofing and Main Contractors, Material Manufacturers, Facilities Management and Architects. Over the last 30 years our experienced technicians have been appointed to carry out surveys on many prestigious buildings throughout the UK.

The solution for detecting pinhole leaks in waterproofing membranes

 

Underestimating the potential consequences of unresolved pinhole leaks in waterproofing membranes can be costly, resulting in significant damage to property if not addressed. Pinholes in a single ply membrane can develop over time to become significant breaches resulting in internal damage or leaks.

Therefore, it essential to identify these at the earliest opportunity, whether it be as part of an integrity test to newly installed waterproofing or part of an ongoing maintenance programme for an existing installation.

 

Attempts to establish the integrity of waterproofing membranes precisely with the naked eye can be time consuming and often proves to be fruitless when the puncture or pinhole is miniscule.  Thornton Consulting provides an accurate and highly professional electronic leakdetection service to locate such pinholes for clients in the building and property sector throughout the UK.

 

Thornton Consulting were pioneers of Electronic Leak Detection and integrity testing of waterproofing membranes in the 1980’s, of which the pinhole test, also known as the “holiday” test forms a part. Since this time, we have built long-term working relationships with Main Contractors, Roofing Constructors and Material Manufacturers. Any existing issues can be identified and resolved avoiding further damage, with a pre-sign off inspection on new installations giving reassurance that the roof membrane is intact. 

 

Pinhole (Holiday) leak detection is carried out with a phosphor bronze brush through which an electrical charge is passed. The brush is then swept across a dry roof surface, with an alarm indicating to the operator the exact location of the breach. Breaches can then be easily repaired by the roofer and retested to ensure the roof is watertight at completion of the test.

 

Thornton Consulting is a customer-focused company with strong core values and is committed to providing a cost-effective and professional leak-detection service compliant to industry standards. Call us today on 01342 410508
