Menlo Park Office Complex in Garden Pathway, Stairs, & Topping Slab

Seamlessly Integrating with Natural Environment

Location: Menlo Park, California Dates Poured: September 2011 and April 2012

ReAct® Blend, a low CO<sub>2</sub> green cement solution, was selected to create a sustainable mix design for a multi-functional garden pathway. The project required decorative concrete that could seamlessly integrate with the garden’s natural beauty and withstand the traffic of company-hosted events and employee day-to-day retreat areas. ReAct® Blend was also used for two stair-wells in the office complex. The requirement was a modern, durable, high-traffic solution that would blend with the overall campus design aesthetic.
