The capillary porosity <br />of the construction material (blockwork/concrete) <br />is interrupted by the combination of active agents <br />(capillary restriction/hydrophobicity). <br />Technical Data: 1) <br />Basis: alkali silicate-siliconate <br />Colour: clear <br />Specific gravity: <br />1.3 g/cm3 <br />pH value: <br />12.2 <br />Cleaning: <br />with water when in the <br /> fresh state <br />Substrate/ <br />application temp.: <br />+5° C to +30° C <br />Consumption: <br />dependent on the porosity of <br /> <br />the brickwork (determined <br /> <br />with a trial bore hole). Min. <br /> 15 kg/m2 wall cross section, <br /> <br />e.g. 36 cm thick wall = min. <br /> <br />5.5 kg per linear metre <br />Packaging: <br />6, 12, 30, 250 kg <br />Storage: <br />frost free, 24 months in the <br /> <br />original unopened container. <br /> <br />Use opened containers <br /> promptly.</p> <p>) The quoted data was determined under standard conditions. <br />Under other conditions of application varying values may result.</p> <p>1</p> <p>Product preparation: <br />I.Low pressure injection method: <br />Particularly suitable when the wall to be treated is <br />already considerably or completely saturated with <br />water. The borehole arrangement is determined by the <br />type and condition of the wall. The borehole diameter <br />is determined by the application method. Borehole <br />spacing is as a rule 10–12.5 cm from hole centre to <br />hole centre. The boreholes are placed horizontally in the <br />pointing mortar or at an angle of up to 45°. The depth <br />of the borehole is about 5cm less than the thickness <br />of the wall. With dense weakly absorbent brickwork <br />as well as horizontal boreholes, chose a double row <br />borehole arrangement. Here the vertical offset should <br />be < 8 cm. With porous natural stone walling place <br />the boreholes in the stone and with dense quarry stone <br />walling in the joints. For wall thicknesses greater than <br />60 cm and on corners boreholes should be drilled <br />from both sides. Before saturating remove drilling dust. <br />Application of AQUAFIN-1K to both sides of the wall <br />around the borehole barrier prevents the AQUAFIN-F <br />from escaping. Insert injection packers in the holes. <br />Walls with large voids, hollow blocks, cracks and open <br />joints up to 5 mm should be repaired with ASOCRET-BM</p> <p>Example of bore hole arrangement – pressure injection</p> <p>1/2</p> <p>03/20</p> <p>before carrying out the injection process. Subsequently <br />inject AQUAFIN-F at a pressure of < 10 bar. Sustain <br />the injection until the neighbouring joint is filled to a <br />satin appearance with AQUAFIN-F. After approx. 24 <br />hours remove the packers and close off the holes with <br />ASOCRET-BM. <br />For information about suitable injection equipment, <br />e.g. HighPump low or HighPump duo of Dittmann <br />Sanierungstechnik GmbH, Hohen Neuendorf, www. <br />saniertechnik.de <br />II. Injection without pressure equipment: <br />Position 30 mm boreholes at a distance of between <br />10 –12.5 cm apart, at an angle of between 45° and <br />30°. The depth of the borehole is approx. 5 cm less <br />than the thickness of the wall. When specifying the <br />drilling angle be aware of the requirement to cover <br />at least one bed joint, and a minimum of 2 bed joints <br />with thicker masonry. It is recommended to place <br />the boreholes in two planes. The distance between <br />borehole centres is determined by the porosity of the <br />wall. The closer together the boreholes are, the greater <br />the success of the procedure. Electro-pneumatic drills that <br />work with minimum vibration (e.g. Hilti) with appropriate <br />drill bits are suitable.</p> <p>Example of borehole arrangement – injection without pressure</p> <p>For wall thicknesses greater than 60 cm and on corners <br />boreholes should be drilled from both sides. Before <br />saturating remove drilling dust. Subsequently insert <br />AQUAFIN-F into the boreholes. It is practical to inject</p> <p>from a storage vessel (hopper with pressure plugs). <br />Saturation time should be a minimum of 24 hours Inject <br />until complete saturation. Afterwards seal the boreholes <br />with ASOCRET-BM. For sealing open joints, cracks or <br />voids use the same procedure as for the low pressure <br />application method. <br />III. Supporting measures <br />After implementation of the wall injection with <br />AQUAFIN-F to combat rising damp additional suitable <br />supporting measures are necessary. This essentially <br />includes plaster repair with the THERMOPAL restoration <br />render system, vertical waterproofing of the exterior <br />surfaces in direct ground with AQUAFIN-RS300/ <br />AQUAFIN-2K/M-PLUS, or COMBIDIC-2K-CLASSIC/ <br />COMBIFLEX-EL, if applicable installing drainage in <br />accordance with DIN 4095, and the rectification of any <br />building defects. <br />Waterproofing the area: <br />Impregnate the cleaned area in a minimum of one <br />application until saturated. Apply AQUAFIN-1K <br />whilst the impregnator is still wet in a minimum of two <br />applications in order to achieve the minimum dry film <br />thickness of 2.0 mm. After the waterproofing slurry has <br />dried, apply the splatterdash coat THERMOPAL-SP over <br />the complete area. Then apply THERMOPAL-ULTRA for <br />condensate retention. <br />Important advice: <br />• AQUAFIN-F is not suitable for exposed surfaces such <br />as concrete, brickwork, render etc. <br />• The WTA data sheet 4-4 forms the basis of the <br />renovation measures against capillary rising damp. <br />Generally exploratory tests (e.g. moisture balance, <br />salts analysis) are necessary. <br />• Protect areas not to be treated with AQUAFIN-F from <br />its effects. <br />Please observe a valid EU health and safety data sheet!</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
