The Problem:

The majority of the houses in slums have inadequate roofs made of corrugated metal, asbestos cement sheets, or clay tiles. The families suffer from unbearably hot living spaces, high maintenance costs, frequent leaks, difficult installation, and a high risk of injury if the house collapses.

The Solution:

Re-Materials has developed an innovative low cost modular roofing tile for local slum housing based on compressed recycled cardboard. These tiles significantly improve household quality of life and can be sold at a much lower price than concrete, filling a market gap.
