The advantage of non-destructive borescope inspections

 

If you aren’t familiar with the technique of using a borescope or flexible inspection camera for non-destructive leak detection, you will be unaware of the advantages of this inspection method when otherwise restricted or inaccessible parts of the building call for water ingress to be identified. This is particularly beneficial in sourcing the leak within areas which aren’t visible to the naked eye. A borescope can best be described as being similar to a medical endoscope, but with a straight and rigid probe where the optical device can view at 90° into the structure. Whereas an inspection camera views in the direction of travel but can be bent to manoeuvre through the structure. Both have their distinct advantages and are invaluable when tracings building leaks.

 

Established more than 30 years ago, Thornton Consulting are industry leaders in the provision of a highly professional leak detection and consultancy service throughout the UK and the Republic of Ireland. Their client portfolio includes Main Contractors, Landlords, Architects, Surveyors, Facilities Management, Building Managers and many more within the property sector.

 

A borescope inspection can be an invaluable asset in assessing the integrity of elements within a cavity wall. This is particularly useful in determining the source of a leak so that further investigations or remedial repairs can be targeted at the right area of the structure.

 

Similarly, a flexible inspection can be used to locate defects in the structure which are difficult to access and confirm the source of leak when combined with other test methods such as a simulated rainfall test. Often an assessment can also me made where different elements of the structure interface and the integrity of each item.

 

These hi-tech surveying procedures with high-resolution cameras are cost-efficient and effective in the identification of any trouble spots in a confined areas when carried out by Thornton Consulting’s highly experienced operatives. Images can be taken and included in a report for reference which will not only give peace of mind that all defects have been accurately located, but clients will also be able to make an informed decision on rectifying areas of concern should any be identified during the inspection.

Locating breaches with electronic leak detection

 

Electronicleak detection for locating breaches in the roofing membrane is an extremely accurate technology used to establish the integrity of the waterproofing system.  Thornton Consulting has been an advocate of wet and dry electronic leak testing methods since the 1980’s as an alternative to the traditional flood testing. Over the years, this has become the preferred method for architects and construction companies in identifying and addressing any ingress locations within the waterproofing material, before signing-off the project.

The accuracy of electronic integrity testing enables even pinhole defects which aren’t easily visible to the naked eye to be located and resolved. This is a non-destructive test procedure which is also environmentally-friendly as the method doesn’t require high volumes of water to be wasted.  Where the membrane is incompatible with the use of electronic equipment, such as EPDM, Thornton Consulting is able to provide alternative testing techniques.

As there is a wide complexity of potential issues with differing structures and waterproofing materials, there is certainly no one-size-fits-all approach to leak detection, which is why it is important for independent test houses, such as Thornton Consulting, to be involved from the outset of a project as we have vast experience in testing all types of flat roofing systems.

Both flat and low-slope roofs are commonly found in shopping centres, hotels, schools and apartment blocks. Thornton Consulting also provides an invaluable and comprehensive Roof Condition Survey, of which electronic leak detection forms a part, but will also assess all potential leak sources affecting the structure and provide relevant information on the performance of the roof and expected life expectancy.

In addition to this, we also offer a building leak detection service which will accurately locate the source and cause of water ingress pathway into the structure. Again, electronic leak detection of the waterproofing membrane can form an important part of this service enabling any breaches in the waterproofing membrane to be identified and resolved, or if no breaches are indicated providing reassurance that the roof covering is performing as expected.

When testing has been completed, clients will be provided with a comprehensive test report which will include specific details relating to the leak locations and recommendations for remedial work which should be carried out to rectify the breach or cause of the leak. Thornton Consulting is an independent test house specialising in the location and detection of leaks in waterproofing systems which have been newly installed, including many prestigious properties. The reputation for an exemplary cost-effective service provided for Main Contractors, Roofing Companies, Architects and Material Manufacturers throughout the UK and the Republic of Ireland has been achieved over the last 30 years, building strong working relationships within the industry sector.

The benefits of flood testing for leak detection

Accuracy and precision in leak detection is crucial to ensure the structure below and any interior mechanical installations are secure from water infiltration and potential damage. Over the years, various integrity tests have been developed, each with specific advantages and limitations of use.  Flood testing to establish the integrity of the waterproofing can be more cost-effective and preferable in some situations where Electronic Leak Detection (ELD) is not possible at the outset. For example, when the existing system doesn’t support ELD testing, such as structures with conductive membranes or where roof finishes are not easily removed, green roofs for example.

 

Thornton Consulting are specialists in the location and appraisal of water infiltration present on roofs and other structures with waterproofing systems, regardless of the ingress point of the leak in the building. This may initially have become visually evident with mould or damp patches appearing on the interior walls and ceilings and can result in serious structural damage over time if left unattended. 

Flood testing carried out by skilled technicians with the application of florescent dyes enable the water pathways to be traced and is suitable for virtually all waterproofing membranes. This method of leak detection is pertinent for any size of building structures, including residential, commercial and industrial premises. Flood testing can also be extremely beneficial for main contractors and roofers of new constructions, to ensure the membrane is completely sealed without defects and there are no potential areas for water penetration, before the work is signed-off.  This is often combined with electronic leak detection so that any breaches can be accurately located.

 

The flood testing is generally carried out over a period of up to 48 hours, depending on the size and roof stability of the structure. Essential pre-testing assessments are made by Thornton Consulting’s technicians to confirm the weight-bearing properties for the estimated volume of water, availability of internal water ingress monitoring during the test period and whether the existing drainage system will withstand the pressure of water release.

 

 

Early assessment and any necessary intervention detected during the flood testing avoids the consequences of greater expense and disruption to rectify water damage to property and content in the future. Thornton Consulting have an experienced team of field testers, consultants and dedicated office staff who all operate to the company’s core values and ethics, providing a cost-effective and reliable service throughout the UK and The Republic of Ireland.  Call us today on 01342 410508 or, if preferred, use the Contact Form on our website.

The importance of roof leak detection

Why is early detection of a roof leak important? Water leaking into the property not only causes structural damage over time, it can also destroy valuable and perhaps irreplaceable contents in residential, commercial or business premises. The longer the seepage is neglected, the greater the expense to rectify the problem. There is also the potential for a risk to health when clean water is contaminated by debris entering from the leak site.

 

 

Locating the source of the leakage isn’t always straightforward and the first signs may be the evidence of mould growth and damp patches on the interior walls and ceilings. Climbing a ladder to search for disrepair can be a dangerous venture without the necessary experience, with the risk of causing further roof damage and even on inspection the leak site may not be obvious to the untrained eye. Thornton Consulting are highly respected specialists in their field, with more than 30 years of expertise in roof leak detection and the evaluation of breaches in all roofing systems throughout the UK and Ireland.

 

 

Although roof damage is often a result of storms and other adverse weather elements, it can also be due to the use of defective materials, sub-standard installation or poor maintenance. Thornton Consulting provide a condition survey service which is valuable for roofing contractors working on refurbishment projects of large commercial and industrial buildings, office and residential apartment blocks. Breaches in the waterproofing membrane can be identified by Electronic Leak Detection, using two different methods as appropriate for the specific membrane type and roof construction. This service provides reassurance to roofing operatives and contractors before completion that there are no breaches in the waterproofing which may cause infiltration in the future.

 

  

As the saying goes, forewarned is forearmed and early awareness of any weak areas in the roof which are a potential leak source can save expensive repair costs required to rectify further deterioration. Thornton Consulting have a dedicated team of experienced consultants, field testers and customer support who are committed to providing a service which is consistent with the long-established company ethics and core values.

The 4 Most Common Causes of Commercial Flat Roof Leaks

A working roof is one of the basic necessities for any business to thrive. If you are worried about your roofs leaking and causing disruption in your business activities, it might be best to consult leak detection specialists UK to get a thorough check done. Property managers must look out for these common causes of flat roof leaks:

1. Clogged Drainage or Ponding Water

If your flat roof doesn’t have a working drainage system, your roof will turn into a swimming pool in no time. Ponding water is the largest cause of roof leakage as just one square foot of ponding water can weigh up to 5 pounds per inch of water.  

2. Damaged Perimeter Flashing

When the flashing is not installed correctly, is damaged or becomes loose due to wind or storm, the edges of the roof cover get exposed which can cause moisture and water to enter the building. Remember that roofing systems contract and expand as the temperature changes through seasons so it can cause the flashing to tear or break. 

3. Open Roof Penetration

If the drains, pipes or other items puncture your roof’s membrane, the penetration will be prone to leaks and you will need a flat roof leak detection UK expert to analyse the cause and suggest the solutions. 

4. Roofing Membrane Damage

As your roof’s membrane ages, it gets prone to cracks, blisters, punctures, and splits, which can allow water inside and also expose your roof’s insulation system.

Your roofing system will age along with your building, sometimes even faster. It is best to consult a UK leak detection company to help you find any possible leaks at the right time.
