Driving sustainable construction in Washington, D.C.
The US capital city shows Holcim at its best
In line with today’s urbanization trends, Washington, D.C., is the world’s first LEED® Platinum city. The capital city of the United States is growing with new construction and renovation projects, many of which are LEED® Platinum and Gold certified.
Home to a high concentration of public authorities, architects and builders, D.C. is at the heart of influencing building norms, regulations and public opinion.
The city is also the locus of all federal governing bodies of the US, making it the place of origin of legislation, from the Infrastructure Investment and Jobs Act to the Inflation Reduction Act. This is where we can make our vision happen when it comes to evolving building norms to allow circular materials and building low-carbon infrastructure.
With iconic projects and operations representing the full spectrum of Holcim's innovative and sustainable building solutions, D.C. inspires Holcim in its commitment to accelerate green growth and decarbonize building.

Georgetown Residence – 55 H Street
The Georgetown Residence houses close to 500 students with nearly 600 m2 of university and common space over 12 floors.
Using ECOPact reduced the building's embodied carbon by 40% and contributed to its LEED® Platinum status. Other sustainable features include energy-use monitoring, dynamic glass, extensive solar panels, sun shading and rainwater collection.

Reverb Apartments
Designed to achieve LEED® Gold certification, Reverb is a mixed-use high-rise community in the vibrant U Street Corridor, comprising over 300 apartments that include affordable units.
The innovative architecture of this new apartment block features unique angles and curves, adding complexity to the ECOPact low-carbon concrete and window construction.
Holcim in D.C. National Parks
The National Mall is one of the most popular tourist destinations in the US. It connects the Capitol Building to the east, the Lincoln Memorial to the west and the White House to the north.
We are proud to play a role in maintaining this national treasure with our building solutions. Every year we restore the paths of the National Mall with our ‘Mall Mix’ of advanced blended aggregates.
Arlington Memorial Bridge
Project completed in 2020
Crossing the Potomac River, nearly 50 million vehicles use the Arlington Memorial Bridge to travel between D.C. and Arlington, Virginia each year. Holcim contributed to the bridge's first rehabilitation since its opening in 1932 – one of the largest infrastructure projects in the US National Park Service’s history.
Lincoln Memorial
Project complete in 2026
Some of the most important events in American history have taken place on the steps of the Lincoln Memorial. This is where Martin Luther King Jr. made his 1963 “I Have A Dream” address, one of the most famous speeches of all time.
Using ECOPact and Enverge spray foam, the undercroft beneath the Lincoln Memorial will soon be transformed into an immersive museum dedicated to the monument and its significance in advancing civil rights.
Lincoln Memorial Reflecting Pool
Project completed in 2012
Dating back to 1927, the Lincoln Memorial Reflecting Pool is the largest reflecting pool in the world. Holcim was part of the restoration of the landmark, from paving new paths to enabling the new and sustainable water-conservation system.
The White House & President’s Park
Project completed in 2023
The home of the US President is the most photographed landmark in D.C. and one that needs maximum security.
Holcim's concrete is used for the more than 1,000 meters of fencing that protect the 18-acre White House Grounds. And 5,000 tons of Holcim asphalt pave the 82-acre President’s Park that surrounds the White House.
Trails around the National Mall
Project complete in 2023
The National Mall links diverse natural and historic landmarks, and offers pleasant recreational paths.
Continuing to innovate, Holcim is involved in the improvements of the multi-use trails connecting Rock Creek to the Potomac Parkway. The 2.4 kilometers of trails will be extended by up to 1.8 meters in width using 1,500 tons of Holcim porous asphalt and 3,000 tons of a D.C. aggregates mix.
PRODUCTION in THE D.C. METROPOLITAN AREA
In addition to Holcim's building materials being used in landmarks across D.C., we also produce many of our products right in the surrounding area. With local production, we help close the transport loop and promote circularity.

Fort Totten
This 13-acre site is the region’s largest ready-mix production facility. The plant is at the forefront of supplying sustainable solutions including ECOPact, and has an on-site concrete recycling center for use of recycled concrete returns. The plant is equipped with a state-of-the-art water treatment facility and dual-source water supply. Fort Totten recently installed solar arrays to generate renewable solar energy on site, helping reduce fossil fuel reliance and power grid demand.
Bladensburg
This 18.8-acre site is a rail terminal that supplies crushed stone, ready-mix concrete and hot-mix asphalt to the D.C. metro area. Sustainability is at its core with a specialty blended, upcycled aggregate base that contains recycled concrete; asphalt mixes with up to 40% recycled asphalt; ECOPact production; and a ready-mix dual-source water supply.
Hagerstown cement plant
The Hagerstown plant supplies to the cities of D.C., Baltimore and Pittsburgh. Here we produce low-carbon OneCem (Portland Limestone Cement) with less clinker than traditional cement. 28% of the plant’s energy is supplied by solar panels. Using alternative fuels since 2008, the introduction of a newly-expanded low-carbon engineered fuel is planned for later this year. This system will replace up to 40% of traditional fossil fuel usage at the plant.
Rockville
This 330-acre serpentinite deposit with over 60 minerals identified has been supplying construction materials since the 1950s. Due to the urbanization of the greater D.C. area, the site is now surrounded on two sides by residential neighborhoods and the Serpentine Barrens Conservation Park. Rockville Quarry is active in community engagement. It hosts a biannual Earth Day Open House event for 2,000-3,000 people, which is recognized by the National Stone, Sand & Gravel Association.
Sparrows Point NewCem slag plant
Sparrows Point produces NewCem Slag. This offers high replacement rates for low-carbon concrete production. NewCem has an advanced sustainability profile that uses less energy for production than standard cement and contains recycled materials.
Fiberglass mat facility
Fiberglass mat is a key component in Malarkey Roofing Products sustainable shingles, used in residential roofing, and also in Elevate ISOGARD insulation and cover boards used in commercial roofing systems. Operations at the state-of-the-art plant began in 2023 to bolster production of our growing roofing solutions portfolio.
Baltimore Terminal
This terminal is geographically positioned to meet the cement demands of our customers in the surrounding region.

Amazon Web Services
Amazon Web Services (AWS) has partnered with Holcim to make AWS data centers in the US more sustainable according to its new design standards. These require that its new US data centers use concrete with 20% lower embodied carbon compared to standard concrete.
Holcim allowed them to double that ambition, delivering a tailor-made ECOPact mix that decreases embodied carbon by nearly 40%. This mix has been used at the AWS data center near the International Airport in Dulles, Virginia.
Metropolitan Park
Furthermore, Amazon has committed to meeting net-zero carbon by 2040 and 100% renewable-energy use by 2030 in its Climate Pledge.
The development of its new HQ, Metropolitan Park, is a cornerstone of this pledge. The entire development will be powered by energy generated at a new 45-megawatt solar farm currently under construction in Pittsylvania County, Virginia.
Amazon will contribute to improving transportation, streetscape, utilities and public space, including a USD 20 million affordable housing contribution. They aim to achieve LEED® Platinum certification with their commitments to sustainable design.
Circular Cities Hub
