SIG Interlocking Brick Supply for Sunrise City Maros Homes

精密连锁砖供应：SIG供货Sunrise City Maros住房

SIG interlocking brick supply for the Sunrise City Maros housing estate in South Sulawesi is the group’s latest push of an innovative wall product into eastern Indonesia. ANTARA on 5 November 2026 quoted SIG Corporate Secretary Vita Mahreyni as saying Precision Interlocking Brick is meant to strengthen the national housing ecosystem and widen access to decent, affordable and safe homes. The blocks for the project are produced by SIG subsidiaries PT Semen Tonasa and PT Varia Usaha Beton, after a construction kick-off on 3 October 2026.

Key Facts

Why SIG interlocking brick supply is aimed at eastern Indonesia

In remarks received by ANTARA in Jakarta on Thursday, 5 November 2026, Vita Mahreyni described Precision Interlocking Brick as SIG’s contribution to the national housing ecosystem through innovative building materials, and to easier access to decent, affordable and safe homes. NLD Corp President Director Tri Wijaya called it an honour to deliver the first houses in Sulawesi that use SIG Precision Interlocking Brick. He said NLD combines subsidised and commercial segments in one estate, while 17 commercial units at the front follow a Scandinavian concept that looks premium and keeps indoor air cooler in Maros’s typically hot climate.

Technical claims and the roles of Semen Tonasa and Varia Usaha Beton

ANTARA reports that the brick is designed for faster installation, material efficiency, quality and sustainability through a high-precision interlocking mechanism, and says the resulting structure is sturdy and resistant to earthquakes and fire. Those points are sourced attributes, not independent tests. Semen Tonasa’s official site, in its 3 October 2026 report, quoted President Director Anis as saying “precision” highlights accuracy compared with interlocking bricks in general. He separated roles: Semen Tonasa produces the cement in South Sulawesi for eastern Indonesia, while the bricks are made with the concrete business unit. He compared conventional building of about four to five months with a target of at most about one month when the product is used with trained workers—a management target, not a guarantee on every plot.

Developer research and procurement implications

Tri Wijaya told ANTARA the material decision followed a one-year study, including a visit to a sample house in Bambu Apus, Jakarta, and the Danantara Housing Expo 2026. On Semen Tonasa’s page he likened the models to homes in Milan and Europe and explained the choice of Maros by its proximity to Makassar and Sultan Hasanuddin International Airport. Both sources record a plan, still being designed, to apply the same material to subsidised houses at another location. homeX, an Indonesian building-materials platform with showroom, warehousing and delivery, treats such a wall product as useful only when site supply is clear and claims can be traced to official sources.
