The European standard "EN 13596 Flexible sheets for waterproofing - Waterproofing of concrete bridge decks and other concrete surfaces through which vehicles can pass - Determination of adhesion strength" standard is one of a set of standards applied to flexible sheets for the waterproofing of concrete bridge decks and other concrete surfaces open to vehicle traffic. is one. This standard includes a test method for evaluating the tensile bond strength properties of the waterproofing board system applied to the concrete surface and asphalt layer.
For the purposes of this standard, bond strength refers to the tensile stress at maximum strength when testing adhesion between different layers in a waterproofing system. Bond strength is key to the performance of the waterproofing system. Bond strength is one of the most important properties when it comes to waterproofing vital infrastructure assets such as concrete bridge decks and other concrete surfaces that vehicles can pass through.
Concrete and steel are the most common substrates, but flexible panels (fiber-reinforced polymer panels) for waterproofing are becoming increasingly popular for bridge decks and other structures such as transit platforms and ramps. EN 13596 standard is among the test methods that determine the bond strength to these surfaces.
Interlayer adhesion, that is, how well the layers of the waterproofing system adhere to each other, is an important consideration. In multilayer systems, the liner, membrane, wear coats and adhesive coats must be bonded together to prevent delamination of the system. In general, membranes and wear/adhesive coat layers consist of polyurethane methyl methacrylate and methyl methacrylate. Such resins bond through polymerization, allowing the open polymer chains in each layer to chemically fuse together and tenaciously bond to the substrate to which it is applied. Other resin systems and sheet systems rely on mechanical bonding, tapes, or veneer weight to hold them in place. There are also hot applied systems that rely on heat rather than chemical bonding for adhesion.
One of the biggest advantages of these adhesion systems, polyurethane methyl methacrylate and methyl methacrylate adhesion technology, is the ability to be recoated and repaired. Over time, heavy traffic can cause routine degradation of the aggregate used for the friction surface in wear systems. In some waterproofing systems, the entire deck along the waterproofing system must be removed and a new system installed. With polyurethane methyl methacrylate and methyl methacrylate adhesion systems, it is possible to remove worn or flaking areas and install a new wear layer that chemically bonds to the original system. This method extends the life of the original system and reduces the cost of full bridge deck repair.
In short, adhesion strength in the waterproofing of concrete bridge decks and other concrete surfaces that vehicles can pass through refers to the sum of the bonding forces between a dry film and the concrete substrate.
