Revolutionizing Sustainable Construction in Rwanda: Geoplast Modulo Formwork and Lightweight Concrete with Politerm Blu

03 MAY 2023

In the pursuit of sustainable and affordable housing solutions, ADHI Rwanda, a leading construction company, has turned to cutting-edge technologies to create homes that are both environmentally friendly and cost-effective. Leveraging Geoplast Modulo recycled plastic formwork for ventilated foundations and lightweight concrete made with Politerm Blu, ADHI Rwanda is spearheading a construction revolution in Kigali, addressing the unique challenges posed by the Rwandan climate and providing quality homes for lower-income earners.


The Geoplast Modulo formwork system has emerged as a game-changer in foundation construction. Traditionally, foundation work can be time-consuming, labour-intensive, and environmentally demanding. However, Modulo formwork offers an innovative and eco-friendly alternative. Crafted from recycled plastic panels, this system reduces the demand for virgin materials and minimizes waste generation. By utilizing recycled plastic, ADHI Rwanda is actively contributing to its commitment to environmental sustainability and the reduction of plastic waste.

Geoplast Modulo recycled formwork, is placed underneath homes by being integrated into its foundation. This creates a ventilated space underneath the building.

What sets Modulo formwork apart is its unique design, specifically tailored to provide ventilated foundations. In the Rwandan climate, with its high humidity levels, moisture management is essential to ensure the longevity and structural integrity of buildings. The elevated structure created by Modulo formwork allows air to circulate beneath the building, preventing moisture build-up and minimizing the risk of dampness and mold. This innovative ventilation system not only contributes to the sustainability of the construction but also promotes a healthier living environment for the residents.

The versatility and efficiency of Modulo formwork have made it an ideal choice for ADHI Rwanda in their mission to provide affordable housing solutions in Kigali. The modular design allows for quick and easy assembly, significantly reducing construction time and labour costs. The lightweight nature of the recycled plastic panels simplifies transportation and handling, streamlining the construction process and contributing to cost savings. Furthermore, the reusability of Modulo formwork minimizes waste generation.

In conjunction with Modulo formwork, ADHI Rwanda utilizes lightweight concrete made with Politerm Blu to create durable and energy-efficient homes. Politerm Blu is a lightweight thermal insulation material that replaces traditional aggregates in concrete mixtures. By significantly reducing the weight of the concrete, Politerm Blu enhances the construction process, making it easier to transport, handle, and place on-site. Moreover, the lightweight nature of Politerm Blu contributes to increased seismic resistance, a crucial factor in regions prone to seismic activity like Rwanda.

The Rwandan climate presents unique challenges, with high temperatures and intense sunlight. ADHI Rwanda understands the importance of maintaining comfortable indoor temperatures while reducing energy consumption. The thermal insulation properties of Politerm Blu offer significant benefits in this regard. By regulating indoor temperatures, Politerm Blu reduces the reliance on air conditioning systems, resulting in energy savings and lower utility costs for homeowners. This not only promotes sustainability but also enhances affordability, making homes more accessible to lower-income earners.

ADHI Rwanda’s utilization of Geoplast Modulo formwork and lightweight concrete with Politerm Blu has transformed the construction landscape in Kigali. These sustainable solutions offer a multitude of advantages beyond environmental friendliness. The construction process becomes more efficient, with reduced project timelines and labour requirements. The lightweight properties of the materials simplify transportation and handling, contributing to cost savings. Moreover, the durability and strength of Modulo formwork and lightweight concrete ensure the longevity of the homes, minimizing maintenance needs and providing a secure living environment for residents.

By incorporating these innovative technologies into their construction practices, ADHI Rwanda has made significant strides in addressing the housing needs of lower-income earners. The affordability of these homes, coupled with their sustainable and energy-efficient features, has made homeownership more accessible and sustainable for those in the lower-income bracket. ADHI Rwanda’s commitment to providing quality and affordable housing aligns perfectly with Rwanda’s vision of sustainable development. As Rwanda continues its journey towards sustainable development, ADHI Rwanda remains at the forefront, driving change, and building a brighter future for all.
