2-component acrylic injection system CERINOL TAP-FLEX method Tapflex The TAP-FLEX method is a waterproofing injection technique for leak points in concrete structures that excels in long-term durability. The Ex-Flex injection liquid used in the TAP-FLEX method is a 2-component methacrylate waterproofing material developed with a focus on safety and durability. The TAP-FLEX method contributes to the longevity of concrete structures and the maintenance of asset value by preventing water ingress into the structure, thereby preventing the deterioration of concrete and reinforcing bars. In underground spaces, structures are constantly in contact with water. Additionally, the water that seeps in is subjected to constant water pressure, creating an environment different from that above ground. The TAP-FLEX method has the following features to efficiently and reliably waterproof against infiltrating water in underground spaces, allowing for long-term effective use of these areas: 1. Can be installed in thick-walled areas in a short time and ensures reliable waterproofing. 2. Waterproofing is possible under pressure conditions. 3. The construction method leaves minimal visible traces of waterproofing. 4. Excellent long-term durability in areas where movement is anticipated. 5. Complies with drinking water standards, passing the leaching test under Ministry of Health Ordinance No. 15.

The reduction in durability of RC road bridges is influenced by the durability of RC slabs and asphalt pavements, which are interrelated factors. Fatigue caused by wheel loads accumulates fatigue in the RC slabs and asphalt pavement surfaces, leading to cracking. The intrusion of rainwater and de-icing agents from these cracks is believed to accelerate the deterioration of the RC road bridge structure. Therefore, the waterproofing effect and durability of slab waterproofing are emphasized. Additionally, the quick release from the public facility of road bridges during renovation work is also an important perspective. The road bridge pavement reinforcement waterproofing system "GGRW Method" developed this time suppresses cracking in the pavement, minimizes damage to the waterproof layer, and allows for quick release. It significantly improves the film strength of conventional asphalt coating waterproof materials and addresses the adhesion issues between resin-based coating waterproof materials and asphalt pavements. A sheet membrane with continuity that integrates waterproofing and reinforcement is created on-site, effectively bonding the pavement and slab with good adhesion to demonstrate its effectiveness in slab waterproofing methods.

Recent changes in lifestyle have led to an increase in the concentration of organic acids (such as fatty acids, acetic acid, lactic acid, propionic acid, etc.) in wastewater, along with higher inflow temperatures, which have become factors in the corrosion of concrete facilities. Traditionally, corrosion prevention for concrete has been achieved by coating the concrete surface with a lining material that meets the quality standards specified in the corrosion prevention technology manual by the sewerage corporation. However, the current quality standards set by the sewerage corporation focus on resistance to sulfuric acid (inorganic acid) derived from hydrogen sulfide gas, and do not address resistance to organic acids. It is explicitly stated in the manual that the effectiveness against organic acids and similar substances has not been considered. Additionally, various cleaning agents and chemicals such as hypochlorous acid and sodium hypochlorite are mixed with organic acids in these building pits. As a result, significant corrosion of the corrosion protection layer due to organic acids has been reported, particularly in the liquid phase and especially in the water intake areas of building pits. Under such conditions, the 'Building Pit Guard' corrosion prevention system demonstrates excellent corrosion resistance performance.

The "TAP Grout Method" is a high-pressure injection waterproofing technique that replaces the pathways of water within concrete structures with resin. By using a TAP injection machine to continuously inject TAP grout solution under high pressure, it reduces the re-leakage that causes deterioration of the structure. In addition to its waterproofing effect, it is a groundbreaking method that improves density and durability, workability and cost-effectiveness, as well as aesthetics. 【Features】 ■ Replaces water pathways in structures with resin ■ Injects TAP grout solution using a high-pressure TAP injection machine ■ Uses O-plugs (stainless steel) *For more details, please download the catalog or contact us.
