Canadian Ky company's representative office in Beijing Su Yue Dalian Kate pi water system engineering Co., Ltd. Zhang Junhang Today, the waterproof market is increasingly prosperous, all kinds of waterproof material contests, including cement-based permeability crystalline waterproof material imported from abroad, its performance was not Less praise, recognized and accepted by the majority of users and industry professionals. The waterproof mechanism of the cement-based permeation-crystalline waterproof material is to form crystals with water, and the water-repellent effect is achieved by the crystals filling the water passages such as capillary pores in the concrete. Due to the unique waterproof mechanism and extremely simple construction process of the cement-based permeation crystalline waterproof material, more advantages and advantages are brought about. Here's a look at the use of cement-based osmotic crystalline water-repellent materials produced by Canada Cayton International in Xinghai Xintiandi Community Project, Xinghai Bay Plaza, Dalian. The community was developed by Taiwan’s famous Shunmai Group and is located next to Xinghai Bay Plaza in the heart of Dalian. The basement of the residential building and the swimming pool of the Xugong Pavilion were constructed using cement-based penetrating crystalline water-repellent material from Caton International, Canada. The residential building is one basement floor and four floors above ground. The ground floor is a garage with a storey height of 4.5m. The foundation is made of a concrete raft foundation. Due to the high groundwater level in Dalian and the project is located near the seashore, the requirement for waterproofing is particularly high. After several selections and considerations, the owner finally decided to use the cement-based penetrating crystalline waterproofing product of Kayton. Among them, Xu Gongguan is the office tower of Dalian Shunmai Group Shantou and has a swimming pool on the fifth floor. The length of the pool is the same as the length of the building in the north and south, and the bottom of the pool is the five floors of the building. This kind of structural design has a high requirement for building waterproof materials: it requires a good protection of the reinforced concrete of the swimming pool, prevents the corrosion of the water by chloride ions on the steel bars, and also prevents the cracks caused by the settlement of buildings. Such dual protection can only be achieved with the use of a cement-based permeation crystalline waterproof material and a flexible waterproof material. Therefore, the waterproof of the swimming pool adopts rigid waterproof. The construction site of this project includes the basement floor, exterior wall, roof, and the inner wall of the swimming pool. Kryst1T1 was used to apply the brush to the water surface. Concrete surfaces must be treated to remove surface foreign matter such as dust, flooding, efflorescence, paint, plaster, or other substances that impede the penetration of chemical components into the concrete. If there are honeycombs, holes, cracks, or other defects on the surface of the concrete, it needs to be repaired before painting Krystol T1. The repair method is as follows: First, loosen the loose stones so that they reach a solid part of the wall, and then wash away the surface sand and soil. , KRYSTOL T1 and water in a ratio of 4:1 into a paste, carefully applied to the surface for anti-seepage treatment, two hours later, using KRYSTOLBARI-COTE reconstituted into a viscous smear deeper hole closed, and then use KRYSTOL T1 paste paste, 1-2 hours later, filled with 1 : 2 cement sand trowel. Firstly, the solid surrounding of the cavity is treated as a solid surface, mixed with KRYSTOLT1 and water, adjusted to a paste ratio of 4:1, evenly brushed around the hole and at the bottom of the cavity. After the initial setting, use the same number as required. The concrete was poured into the hole. After solidification, a 30mm x 30mm furrow was scooped along the joints around it, and then it was thoroughly coated with a well-tuned KRYSTOL T1. After 1-2 hours, the mortar was filled with 2 cement mortar. The cold joints formed by the long time between two concrete placements are not designed to take any technical measures to prevent the leakage caused by concrete shrinkage. Therefore, it must be repaired according to technical requirements. More than width. Cracks above 5mm are also repaired. With the crack as the center, a groove with a width of 3 cm and a depth of 3-4 cm deep was cut along the crack and flushed with water. KRYSTOLT1 and water were mixed into a paste in a ratio of 4:1, and were carefully applied to the groove. After epitaxy, 2 hours later, KRYSTOLBAR-ICOTE was mixed into agglomerates and compacted in a groove, and then the surface was homogenized with KRYSTOL1. Since KRYSTOLT1 waterproof parts to be painted have basement floor, exterior wall, ceiling and inner wall of the swimming pool, and various parts need to be processed in different details, the summary is as follows: The anti-floating anchor reserves the treatment of reinforcing steel bar, its purpose is to prevent water Infiltrate the inside of the concrete along the joints to prevent the steel from being attacked by the water. First, clean up the upper end of the anti-float anchor, remove the concrete slag and other impurities with steel brazing, reach the hard bottom and the required height, then wash the sludge dust with water, clean the cement-based penetrating crystal Waterproof material, mix the powdery KRYSTOLT1 with water into a paste, use 5 parts of KRYSTOLTl: 2 parts of water, stir well, apply the hook on the anti-float anchor rod, turn it up by 20cm, check the reinforcement carefully. Whether there is a gap in the contact area between the concrete, if there is a gap applied KRYSTOLT1 sealed. KRYSTOLT1 is applied to the surface of the steel bar erected vertically. Generally, the thickness of the cushion is about 10cm, which is not very dense. It is easy to form a waterway around the reinforcement-relief anchor bar where concrete is in contact with the surrounding concrete. KRYSTOLTl can be brushed below the reinforced water stop ring. The growth of KRYSTOLT1 crystals can be filled with small cracks caused by the vibration of the rebar. After pouring the concrete into the mat, the KRYSTOLT1 penetrating crystalline waterproof material concentrate waterproof layer on the cushion is integrated with the KRYSTOLT1 brushed around the reinforcing steel to seal the waterway and prevent water seepage. It is necessary to wait until the concrete is completely solidified before disassembling the template; the concrete shovel at the root of the through-wall screw will be dropped into a concave shape, and then cut off by gas welding. In particular, the wall-mounted screws below the horizontal construction joints must not be bent off by bending. After brushing KRYSTOLT1, use 1:2 cement mortar to apply pressure and smooth it. After solidification, apply KRYSTOLT1 to achieve anti-leakage. There are many water pipes in the swimming pool, and all of them are plastic pipes, which have greater flexibility. The gaps around the plastic pipes are rigidly and flexibly combined. The rigid waterproof material fixes the plastic pipes, and the flexible waterproof material prevents the plastic pipes from shrinking due to cold or heat. Leaking water. The method of operation is as follows: After the pipeline is positioned and installed, a trench of 2cm deep and lcm wide is to be cut around the pipeline. After cleaning, the polyurethane is poured into the trench and filled to a depth of lcm. After 24 hours, it is solidified and sealed with KRYSTOLBARI-COTE. When the pipeline and the ground to wipe out a 2 cm R angle, then brush KRYSTOLT1. The concrete base Surface Treatment, and after processing the details of the structure, you can carry out a large area of ​​brushing. Before painting, the surface of the concrete should be wetted with water to make it saturated, but the surface must not contain water. Mix KRYSTOLT1 and water in a ratio of 5:2. The blended mixture was brushed onto the surface of the concrete with a bristled brush in a circular manner. The dosage requirement is 0.8 kg per square meter of KRYSTOLT. 1. The waterproofing of the concrete floor is on the upper surface of the foundation cushion. In this way, when the base plate is burned, it is like a layer of fresh Krystol coating on the bottom surface of the bottom plate, which not only facilitates the construction, but also does not affect the waterproof effect. The waterproofing of the wall is to apply the Krystol coating to the surface of the outer wall. The waterproofing of the basement ceiling is to apply the Krystol coating on the surface of the ceiling. In addition to applying a layer of Krystol coating on the inside of the pool, the swimming pool will also provide a layer of flexible waterproofing on the surface of the Krystol coating. The inside corner of the wall is the intersection of the facade wall and the floor, and it is prone to leak brush. After the vertical and horizontal waterproof layer is painted and reaches the initial setting, it is painted with a width of 4 cm. Then use a 1:2 cement mortar to wipe out a 2 cm R corner, and then apply the brush to KRYSTOL T1 to seal it. This practice can achieve secondary closure and prevent shear cracking. Post-pouring tape is the key part of waterproofing. Unfilled before the bottom and both sides of the treatment: After the clean water poured in the belt, clean up the impurity impurities on the bottom and side walls, both sides of the barbed wire must be handled clean, can be burned gas welding. KRYSTOLT1 is applied to the bottom of the post-draining belt. (KRYSTOLT1 can also be applied to the bottom and 0.8 kg per square metre is evenly spread on the bottom of the post-draining belt. This should be done within thirty minutes before the concrete is poured.) Mix KRYSTOLT1 and water in a ratio of 5:2 and apply on both sides of the inner wall to increase the adhesion of the old and new concrete and the gap of the sealed concrete. This work can be carried out 1 day before the concrete is poured. When the concrete of the post-poured belt is poured and solidified, KRYSTOLT1 will gradually penetrate the new concrete and seal the small cracks. Treatment of the post-pouring zone: The construction joints of the joints on both sides of the post-pouring zone are easy to form voids due to the combination of the two pouring concretes, which is one of the main causes of water leakage and also a key treatment site for waterproof construction. First, scoop out a 3mm wide x 40mm deep ditch along the joint of the old and new concrete of the post-pouring zone, wash it off with water, and use KRYSTOLT1 and water to make a thick paste at a ratio of 5:2. Strictly apply to the ditch and epitaxial, 1- After 2 hours, use 1:2 cement ash to fill and smooth, after the basic solidification, and then use a uniform KRYSTOLTI uniform brushing surface and post-doping belt into one. Re-use 1:2 cement sand gray thickness 25mm, width 400mm protective layer to prevent damage. After the penetrating crystalline waterproof layer has been applied, a 25mm thick screed is wiped with 1:2.5 sand to prepare for the next flexible waterproof construction. Leveling sand ash should be sturdy and smooth, with a slope of 5/1000 to the outside of the pool to prevent accumulation of water. The surface needs to be calendered. There must be no sanding or hollowing. The angle of the sun must be 5mm and there must be no burrs. The pipeline must be smoothed around. Before the construction of flexible waterproofing, it is necessary to check carefully whether the mortar leveling layer has the construction conditions. The mortar must be smooth and firm, must be solidified and dry, and must not be wet. Dust should be removed and the temperature should be above 5°C above zero. With these conditions, the polyurethane coating can be applied. The polyurethane A and B groups are blended and stirred 1:2, wiped with a squeegee, and then sequentially proceeded from the wall surface. Once again, the thickness reaches 0.7mm-0.9mm. After surface construction, ground construction is required, scraping and scraping are required, and the circumference of the pipeline is brushed around the circumference for the second time. The walls of the room are turned upside down by 500mm. The gap between the door and window frame and the bottom of the door and window shall be sealed to prevent water leakage. Seal the doors and windows with adhesive tape. Frames to prevent water-proof material from contaminating the door and window frame. The surface was solidified in 4 hours and solidified after 8 hours, and the second pass of construction was possible. After the polyurethane waterproof layer is solidified, the surface is relatively smooth, and it is easy to fall off when plastering, and the metal mesh can be prevented from slipping off. The metal mesh is first placed in position, the polyurethane is nailed, the anchoring piece is placed on it, the nail is anchored with a nail gun, and then the surface is painted with polyurethane, and the thickness is 1 dish of 6.1 KRYSTOLT1 impermeability agent. After adding water, the PH value reaches 13; therefore, rubber gloves and protective glasses should be worn during the construction operation. 6.2 When the temperature is too high, after the construction of the brushed work surface is completed, it shall be fully maintained, and if necessary, it shall be sprayed with water in a mist to prevent the coating from cracking or forming. 6.3. The deployed material must be used within 30 minutes. If it is not used up, it should be discarded. Do not mix it with new material and mix it again. 6.4, construction tools and containers should be clean, no oil and pollutants, after use should be promptly cleaned. 6.5. The construction surface treated with KRYSTOLT1 shall be prohibited within 12 hours; during the 20th and the next time, the rain shall be avoided; the vehicle shall be avoided within five days; the material containing Portland cement may be used on KRYSTOLT1 after three hours. But with other materials, it will take 28 days. The project has been completed for one year and no leakage problems have been found during the year of delivery. This shows that the waterproofing of the project is quite effective. In this case we can see that the cement-based osmotic crystalline waterproof material can be used alone or in combination with other different types of waterproof products to achieve a satisfactory waterproof effect. At the same time, it can be seen that the cement-based permeation crystalline waterproof material is flexible and practical, and the construction operation is simple and convenient. This brings a series of benefits, which will better serve waterproof engineering.
