<h1>Planungs-und-Anwendungsratgeber-AQUAFIN-WM12_EN_1722.pdf</h1> <p>Waterproofing and repair of buildings</p> <p>Planning and <br />application consultant <br />for fresh concrete waterproofing <br />membranes AQUAFIN®-WM12. <br />If tensile cracks occur in water-tight concrete, expensive crack injection is often <br />the only solution. This is where the fresh concrete waterproofing membrane system <br />AQUAFIN-WM12 comes into play. We want to show our capability to fill <br />tension cracks from the outset and seal them securely from behind. <br />Problems Solved.</p> <p>Problems Solved. For your reinforced concrete <br />building projects <br />High-quality buildings must be particularly protected against the ingress of water. Here, <br />the guideline for water-impermeable concrete structures (WU-guideline) offers an excellent <br />basis, with good planning and execution, assures a long useful life for the building. <br />Unfortunately, very small tension cracks occur during construction, which allow the water to <br />penetrate into the building. These must be repaired at great expense by means of crack <br />injection. To avoid this, a fresh concrete waterproofing membrane is applied in advance. <br />The aim is to assure maximum success for the client in the use of his building. This will only <br />succeed if, in addition to high-quality product systems, there is also smooth and coordinated <br />planning, and professional and qualified execution. This handbook is based on our current <br />building experience and the results of our tests. <br />Thank you for your trust and your interest in the complete AQUAFIN-WM12 system. <br />We wish you lots of success in the implementation of your projects. If you have any <br />questions, do not hesitate to contact us.

This starts with preparing the substrate. <br />Application substrates: <br />Floor slab</p> <p>Vertical surfaces</p> <p>• Clean lean concrete layer <br />smoothened or levelled <br />• Perimeter insulation laid free of voids <br />• Compressed, pressure-stable, <br />capillary breaking layer</p> <p>• Perimeter insulation <br />• Cementitious surfaces <br />• Formwork</p> <p>Application substrate perimeter insulation <br />The substrate must meet the following requirements: <br />• The substrate must be sufficiently load-bearing, level, firm and pressure-resistant in order to compensate <br />for the loads that occur during the laying and concreting work. <br />• Larger surface irregularities or projections are to be avoided or evened out in advance. <br />• In the case of applications underneath floor slabs on compacted, pressure-resistant, capillary-breaking <br />layers, there must be no sharp-edged or pointed components. <br />• Blinding layers may have a maximum surface roughness of 10 mm. <br />• Clean and free from coarse and disruptive dirt. <br />• May be damp but should be free of standing water. <br />• Free from critical contaminants (oil, grease, dust, etc.).</p> <p>4</p> <p>schomburg.com</p> <p>Tool <br />We recommend the following tools for optimum processing of the fresh <br />concrete waterproofing membranes:</p> <p>• Cartridge press for tubular bags <br />• Hot air welder (e.g. Leister) <br />• Pressure roller <br />• Impact stapler <br />Additional small tools: <br />• Cast iron shears <br />• Craft knife <br />• Set square <br />• Cutting mat <br />• Metre stick <br />• Marker <br />• Fixing strips</p> <p>Joint system</p> <p>Overlapping area of fresh concrete <br />waterproofing membrane <br />The overlapping width of the fresh concrete <br />waterproofing membranes is 5cm.</p> <p>Joining option with machine welder</p> <p>Joining option with assembly adhesive</p> <p>Joining option with hot air welder - hot air <br />welder joins the membrane overlaps to <br />a width of 4 cm.</p> <p>System-tested universal sealant AQUAFIN-CA <br />for full-surface bonding of the overlapping <br />area and architectural features.</p> <p>schomburg.com</p> <p>5</p> <p>Feature waterproofing <br />Processing sequence <br />The sealing of transitions at architectural features requires precise planning and <br />careful implementation. After preparing the substrate, the first step is to form <br />the corners and create the edge upstand in the wall/floor transition.
