<h1>AQUAFIN-i380_GB_0317.pdf</h1> <p>Sequentially applied <br />horizontal barrier</p> <p>AQUAFIN®-i380</p> <p>AQUAFIN®-i380 is a guaranteed solution for sequentially applied <br />horizontal barriers. This new silane-based injection cream requires no <br />pressure when applied to prevent rising dampness in masonry works by <br />inducing a “hydrophobic” property in the injected substrate. <br />AQUAFIN®-i380 functions at moisture saturation levels up to 95% <br />when tested in accordance with WTA work sheet 4/4/04 (Injection <br />of Masonry Works Against Capillary Rising Dampness). <br />Classic “silicifying” injection products can only be applied with pressure <br />when moisture saturation levels exceed 60% whilst AQUAFIN®-i380 <br />is entirely effective when applied without the use of pressure even when <br />saturation levels reach 95%.</p> <p>How does <br />AQUAFIN®-i380 work? <br />Due to its special composition, the molecular size of the active ingredient is <br />much smaller than classical products. It also does not react with water, but <br />solely with the substrate. The “hydrophilic nature“ (great affinity for water) of <br />the active ingredient means quicker dispersion in the capillary water and <br />eventually leading to the so-called “self-injection” property, achieving 100% <br />saturation of the pores. <br />After reacting with the substrate, the capillary walls become hydrophobic <br />and rising water or dampness due to osmotic pressure (absorption of water <br />in the capillaries) is prevented leading to the eventual drying out of the <br />substrate which also becomes water repellent.</p> <p>Untreated <br />masonry work</p> <p>Masonry work treated <br />with AQUAFIN®-i380</p> <p>Application without pressure <br />The distance between bore holes as well as their positioning (single <br />or double row) is determined by the absorption of the masonry work. <br />The closer the bore holes are together, the greater the degree of <br />success. Electro-pneumatic drills, which operate as free from vibration as <br />possible, are suitable for boring the holes. Where walls are thicker than <br />60 cm, we recommend injection under pressure with AQUAFIN®-F. <br />As a rule, 12 mm diameter holes or greater are drilled at 10.0 cm to <br />12.5 cm spacings (axis-to-axis) and at an inclined angle above 0° and <br />up to 45° measured to the horizontal plane. The depth of the holes <br />should be approx. 2 cm shorter than the masonry work thickness. Ensure <br />that the positioning of the bore holes penetrates at least one horizontal <br />masonry joint (or two for thicker masonry works). With substrates of low <br />or no absorption it is recommended that the bore holes are positioned <br />on two levels within the joints. The height difference being less than 8 cm. <br />Thoroughly remove dust or debris resulting from the drilling before <br />commencing with the injection works. This is to ensure the greatest <br />uptake of the active ingredients into the masonry works. Injection must be <br />carried out with a suitable hand-operated barrel gun with an appropriate <br />attachment. <br />Slowly squeeze AQUAFIN®-i380 out into the bottom of the bore hole – <br />whilst gradually moving the injection tube out to ensure the bore holes <br />are completely filled. Plug the bore hole openings with ASOCRET-BM. <br />The advantage of using AQUAFIN®-i380 is its creamy consistency and <br />that it does not flow out or fill unseen voids like traditional low viscosity <br />liquid products when applying to horizontal holes or where there is <br />inhomogeneity.</p> <p>Removal of render from damaged areas</p> <p>Marking out the bore hole spacing</p> <p>Drilling the holes</p> <p>Removing dust & debris from after drilling</p> <p>Injecting the cream-consistency AQUAFIN®-i380</p> <p>Properties and Advantages <br />• Ready to use <br />• Solvent-free <br />• Hydrophobic <br />• Excellent penetration <br />• Prevents “capillary water” migration <br />• Simple and effective application <br />• Low consumption <br />• Non-hazardous with low emissions <br />• WTA approved; even when moisture saturation levels reach 95% <br />• Highly concentrated (80% active ingredient content) <br />• Excellent dispersion <br />• Creamy consistency prevents flow into cracks, cavities or voids <br />• Applied without pressure; simply extrude from a barrel type gun <br />• May also be mechanically applied using low pressure <br />• No dilution or pre-mixing necessary <br />• Quantities easily calculated <br />Areas of Application <br />For producing sequentially applied horizontal barriers in accordance with <br />the WTA work sheet 4-4-04/D “Injection of Masonry Works Against <br />Capillary Rising Dampness”, against rising dampness up to 95 % moisture <br />saturation in masonry work constructed from e.g. brick, clinker, lime-sand <br />blocks, natural stone including joints. <br />Substrate Preparation <br />Remove old damaged render, paints or coatings from the substrate up to a <br />height of 80 cm above the neighbouring area of damage either visibly or <br />through examination. Rake out crumbly pointing to a depth of 2 cm deep <br />and mechanically clean the area. To replace masonry joints we <br />recommend THERMOPAL®-GP11. Where using low pressure equipment, <br />we recommend blocking the injection area with AQUAFIN®-1K. <br />Technical Data: <br />Basis: Silane <br />Consistency: <br />creamy <br />Colour: <br />white, transparent once dry <br />Specific gravity: <br />approx. 0.9 g/cm³ <br />Active ingredient content: <br />approx. 80 % by weight <br />Substrate / <br />application temperatur: <br />+5 °C to +30 °C <br />Packaging: <br />12 x 550 ml sausage/box <br /> <br />and 5 l packs <br />Storage: <br />12 months in original unopened packs <br />Consumption: <br />refer to valid Technical Data Sheet</p> <p>Subject to changes.
