Material Testing Laboratory NATA Accredited
Vector Mapping, sponge and other methods are able to detect breaches in waterproofing membrane applications and may be prescribed in specifications. ELD creates an electric circuit through a non-conductive membrane to find coating film discontinuities that are not just click the following internet site readily visible. Electronic Leak Detection is a testing method applied to many waterpoofing membranes as a method of checking for the continuity of the membran
Roughness measurements reveal surface topography variations that influence fouling development and solute interactions. Zeta potential measurement quantifies surface charge magnitude and sign, with highly charged surfaces showing enhanced resistance to colloidal fouling but potentially increased organic macromolecule attraction. Narrow PSD distributions support high selectivity for separation applications, while broader distributions accommodate feeds with variable particle sizes. Pore size distribution (PSD) characterization identifies the distribution of pore diameters throughout the membrane, typically ranging from 0.001 to 10 micrometers depending on membrane type. This guide outlines essential characterization parameters, required instrumentation, standardized testing protocols, and proper interpretation of result
A well-designed gradient ensures that water is efficiently directed towards drainage points, minimising the risk of pooling and ingress. It encompasses various aspects of installation, from substrate preparation and membrane application to ensuring proper water drainage and membrane termination. The Projex Mission is to source and supply technically excellent products to meet the needs of owners, designers, just click the following internet site insurers and operators of buildings and structures for specialist protection against water, industrial liquids, impact and corrosion risk
Seams on sheet membranes are also difficult for this method to accurately test as the thickness at the seam is doubled; high voltage current cannot travel laterally through a seam defect. However, not all ELD testing equipment can find breaches on vertical substrates, multiple horizontal breaches in a single test or test semi-conductive coatings – i.e. membranes such as Black EDPM, Black Butynol or polyurethanes tinted with Carbon black. ELD works by creating an electrical field between the membrane surface and a conductive deck or substrate [ie Concrete] which is earthed to the building.

D) Requires temporary dams to be installed to partition off individual wet areas from non-wet areas in buildings, AS/NZS 4858 is the primary Australian standard that relates to the physical performance properties of waterproofing membranes specified for use in wet areas such as bathrooms, kitchens, laundries and wet rooms, to prevent water ingress and protect structures from moisture damage. The thickness readings are obtained by measuring the time taken for the ultrasonic signal to propagate from the probe to the coating/substrate interface and back. Independent Testing Australia (ITA) is equipped with specialised apparatus to test materials and provide data to coating manufacturers, specifiers, builders and waterproofers to determine product suitability for use in the Australian construction industry and satisfy documentation requirements of the Australian Building Code (BCA), the National Construction Code (NCC) and Australian Paint Approval Scheme specifications (APAS). The EFVM® leak detection system makes flood testing waterproofing membranes a thing of the past …
Effective water management is a critical component of external waterproofing, necessitating the implementation of proper falls and drainage to guide water away from the structure. Our approach combines in-depth industry knowledge with rigorous adherence to these standards, ensuring that every waterproofing system we design offers superior protection against water damage. The standard helps builders and contractors specify materials that are not only waterproof but also resistant to UV radiation, temperature variations, and physical damage. The secret is the control of the membrane application from the supplier to the contractor as well as the onsite support and quality control of the installation. During this time, we have noticed that the main causes of waterproofing failure is in the design, application, incorrect membrane and installation. Projex Group Pty Ltd has been supplying the Australian market with waterproofing systems for over 30 year
Waterstops for use in water retaining and water excluding structures where a positive seal is required. Primer options that just click the following internet site enhance the adhesion of waterproofing and coating systems to various substrates. HDPE Bentonite Sheet waterproofing membranes with expandable Bentonite adhered to high density Polyethylene (HDPE) for horizontal, vertical and lagging applications. Tremco offer various reinforcing products that are used in conjunction with fluid applied waterproofing membrane
