Postensa
Monterrey
To improve durability, reusability, and finish quality in formwork, Postensa implemented Polycrete by WAS Co—recycled polypropylene sheets—as a sustainable alternative to conventional phenolic boards in the Torre Rise project, the future tallest tower in Latin America. The solution was tested on retaining walls, slabs, and core walls, showing excellent performance in durability, moisture resistance, ease of demolding, and surface finish. The implementation addressed challenges of frequent board deterioration, poor moisture performance, and high labor costs in cleaning and repairs.
The project will use 500 formworks, with 30 kg of plastic recycled per formwork, giving a total of 15 tons of recycled plastic. Recycling 15 tons of plastic = between 22.5 and 45 tons of CO₂ avoided = ~85,500 kWh of energy saved = It prevents the equivalent of more than 22,000 m³ of landfill volume and the release of microplastics into the environment. Using 500 Polycrete panels saves $53.7K vs. plywood, cuts 60% waste, needs no release agents, and is made from 100% recycled plastic.
With a new constructive system, lego type, to reduce construction costs and construction time. We are in the process of applying for several patents of different polymer compounds that we have developed, as well as the new lego-type construction system that we design for the homes we are building. We work based on generating 100% sustainable products, with a short, medium and long term objective, as well as their reuse or recycling after use. For example, the homes we are about to build are based on recycled polymer compounds, with non-toxic minerals and other additives developed by ourselves.
