Greenspace Redefined:

Mary Bartelme Park, Chicago

At the heart of Chicago’s Mary Bartelme Park lie gleaming steel sculptures and a radiant white plaza paved with TX Active® photocatalytic cement. Not only do these pavers maintain their brilliant white hue, reducing cleaning and maintenance costs, but they also actively combat air pollution. Crafted by Unilock® Chicago, the plaza stands as a testament to innovation in green design. Opened in 2010, this park is named in honor of Mary Bartelme, Illinois’s first female high-court judge and a champion for children’s welfare.

TX Active®: A beacon of eco-conscious design that goes beyond just aesthetics.

Good, Clean Design

For more than a decade, our technology center has been studying photocatalysis and applying its applications in cementitious materials. Among our findings: cementitious materials represent the ideal solution for spreading photocatalysts widely and evenly over both the horizontal and vertical surfaces of architectural and structural elements.
