JAKARTA - Green Open Space (RTH) plays an important role in preserving the environment, especially as an infiltration area for water resource conservation. However, the use of vacant land into office buildings and residential areas as a result of the pace of urbanization, has left little room for green open space.

PT Semen Indonesia (Persero) Tbk (SIG) offers porous concrete technology, ThruCrete, as a high absorption-powered violent solution for water runoff manufacturing on the surface (surface run-off) and optimizing water absorption into the ground.

SIG's Corporate Secretary, Vita Mahreyni, said that good water management is a feature of a sustainable city, which is shown by its ability to absorb and store rainwater. That way, the availability of water sources is maintained and environmental risk potential such as flooding can be minimized.

The porous concrete is an innovative building material solution that is environmentally friendly to support sustainable development in Indonesia. This cutting-edge technology from GIS is able to move rainwater from the surface of roads, sidewalks, parking lots, and park areas into the ground with an absorption rate of >250 L/m2/minutes, thus supporting the green area coefficient (KDH) program 30% zero run-off to improve the quality of life of the community," said Vita Mahreyni, in her statement, Tuesday, June 10.

The innovative concrete solutions from GIS have been applied in a number of strategic areas in Jakarta in the pedestrian path revitalization project in several areas, including Gelora Bung Karno, Kebayoran Baru (Blok M, Barito, and Melawai), Istiqal Mosque, Jl. KH Wahid Hasyim, Jl. Raya Fatmawati as well as several green open space locations in Jakarta, including Lebak Bulus, Bambu Apus, Panglima Polim, Lubang Buaya, Pasar Minggu, Pondok Labu and Kramat Jati. Apart from Jakarta, ThruCrete was also applied to the Tegalega, Bandung & Square, Depok City, West Java. In East Java, ThruCrete was applied to the Juanda Airport shoulder taxiway in Sidoarjo, to help overcome the water runoff that had caused flooding.

In addition to porous concrete, GIS also has a row of other innovative concrete solutions that have advantages in their respective designations, including high-performance concrete for road repairs overnight (SpeedCrete), color decorative concrete (DokoCrete), concrete for low-carbon (LocoolCrete) general applications, and paving porous blocks as solutions for inundated areas.

In its application, porous concrete can also be combined with decorative concrete to provide an aesthetic display with a wide selection of colors and high quality patterns. In addition to being durable and easy to care for, decorative concrete also has a safe anti-slip texture applied to pedestrian paths to support the safety of pedestrians.

Vita Mahreyni added that the application of innovative concrete solutions from GIS not only had a positive impact on environmental conservation, but also encouraged the creation of a safe and comfortable public space for the community. Moreover, the innovative concrete solution of GIS is also more environmentally friendly because it is produced with GIS green cement which is lower in carbon emissions by up to 38 percent compared to conventional cement.

"SIG is very focused on quality and quality aspects of its products, taking into account aspects of environmental and social sustainability and providing sustainable added value for stakeholders. As a state-owned company providing leading building materials solutions in Indonesia, GIS is always ready to support development absorption throughout Indonesia," said Vita Mahreyni.
