JAKARTA - Concrete duct is an important component in building construction. Concrete ducts are usually functioned as a barrier between floors in high-rise buildings, can also function as a roof or better known as a non-concrete roof.

Concrete ducts are currently quite popular and in demand as roofs because of their sturdy nature, easy to clean, easy to maintain and can be used as a multipurpose area. In addition to the functional aspect, not concrete can also add to the aesthetic value of a building.

The formation of the non-concrete itself is usually through a casting process with material elements that play a role, namely cement, sand, gravel, water, concrete additives and areas that have been prepared with concrete reinforcement to strengthen the building structure.

Construction of a house with a concrete roof is not a difficult thing to do, but it is still an investment cost for the family to live in, so it is still necessary to pay attention to the casting process and materials.

If the concrete casting process is not carried out perfectly, it can cause problems in the future such as porous concrete and a problem that often occurs is leakage. Here are some of the causes of leaking concrete:

1. Imperfect concrete casting

The ratio of the mixture of materials that are not suitable can also make the concrete imperfect. There are times when the casted concrete has lumps, the flowability is not good so that the concrete does not fill the entire casting area. This can also cause cavities in the castings and even result in porous concrete. For this reason, concrete additives such as BETONMIX are needed, only 1 percent of the cement used is used.

2. Castings that do not meet standards

Do not hesitate to consult technical matters with architects, contractors, or people who are more familiar with buildings because concrete standards are certainly quite complex. One example is the thickness of concrete, it is recommended that the minimum concrete thickness according to the standard is 12 cm or can depend on needs.

3. Unsmooth concrete surface

The resulting concrete with large and not fine pores is more prone to openings for water to enter. In addition to the pores, it is also necessary to pay attention to the presence or absence of cracks on the concrete surface. Wide cracks in the roof of the concrete can be more fatal than the pores.

4. Improper use of waterproofing

Ordinary leak-proof coating is not necessarily enough to coat the roof and not concrete, let alone ordinary paint that does not have a waterproof function. For non-concrete roofs, it is recommended to use a leak-proof coating made from Aquaproof Pro polyurethane acrylate which has been specially formulated.

After knowing the cause of the leaking concrete duct, the solution to overcome the leaking concrete dak which of course can be applied is by using quality materials and the right processing process, following the product application guidelines which are usually listed on each package. The following are product application tips ranging from concrete casting to leak-proof paint coating processes:

1. Concrete Casting with BETONMIX

BETONMIX is one of the products from Aquaproof which is used as a concrete mixture. With Superior Plasticizer Technology, the benefits of BETONMIX are felt to make casting easier, improve the quality of concrete, shorten the time of hardening of concrete (14 days old concrete is equivalent to 28 days old concrete without Betonmix).

How to use:- 1 kg of BETONMIX is used for 2-8 bags of 50 kg cement or 0.2 - 1 percent of the weight of cement- Mix BETONMIX with water to be used. The use of water can be reduced by 10 - 30 percent of normal water requirements.- Enter the mixture of water and BETONMIX into the sand, gravel, and cement mixture, then stir until smooth- Perform casting as usual, try to finish the concrete mix in less than 1 hour

2. Primary coating of a mixture of super cement and cement

Super Cement is a milky white liquid with Bond Booster Technology which functions to improve the quality of cement. A mixture of Super Cement and cement is the right combination as a primer. Besides functioning to close the pores in the plaster, the mixture can also increase the adhesion to the substrate and bind the small particles that are still left behind.

How to use: - Clean the surface to be coated with primer from moss, fungus, cement residue and other dirt - Mix Super Cement and cement as a primer with a volume ratio of 1:11/4 and mix until smooth - Apply Super Cement primer and cement using a brush or roll one time coating

3. Aquaproof Pro waterproofing coating

Aquaproof Pro is a leak-proof coating formulated with the latest innovations high performance polyurethane acrylate to coat horizontal or vertical structures, both as interior and exterior coatings.

Aquaproof Pro has good waterponding resistance properties, so it is certain that Pro will coat non-concrete roofs that are prone to waterlogging. Aquaproof Pro is available in two packaging sizes, namely 4 kg and 20 kg with a choice of gray pro and white colors. Besides being certain that Pro does not overcome leaking concrete, Aquaproof Pro is also elastic, has strong adhesion, is durable, UV resistant and minimal stains.

How to use:- After the primer is dry, apply Aquaproof Pro without mixing with water. Application can be done by brush, roll or sprayer - Wait for the first coat of Aquaproof Pro to dry and carry out a second coat process, if possible apply the second layer across the first coat. Every 1 kg of Aquaproof pro can be used to coat an area of 1 m2. - Especially for joints, joints between fields or parts that are prone to cracking, it is highly recommended to use Aquaproof Polyester Mesh when the first layer of Aquaproof Pro is still wet.

Aquaproof concrete roofing solutions with the products mentioned above such as BETONMIX, Super Cement, Aquaproof Pro and Aquaproof Polyester Mesh are readily available at modern building specialty outlets and various building stores throughout Indonesia.

Aquaproof in addition to providing solutions to various building problems, is now getting closer to consumers by having official stores in marketplaces such as Tokopedia, Shopee and Lazada so that consumers can shop more easily and of course equipped with free consulting services related to building or product problems.
