Founded in 1975 in Antrim, Northern Ireland, the company has grown from its humble beginnings of supplying admixtures to concrete plants into a powerhouse offering a diverse range of high quality, high-performance products across multiple sectors, including builders’ merchants, tiling, flooring, silo mortar and highways.
For five decades, Larsen has stayed true to its core values:
- Built For Professionals
- Trusted Reputation
- Technical Experts
- Customer First
- Support Local
These principles have driven the company’s vision: to provide customers with exceptional service and support while delivering quality products that meet the demands of the ever-evolving construction industry.
A Legacy of Innovation and Expertise
The journey of Larsen Building Products began in 1975 in Antrim, Northern Ireland with a focus on supplying admixtures to concrete plants, offering professional products that improved the quality and performance of concrete. Moving premises to Belfast Harbour Estate in 1984 saw the business expand into epoxy resins, wood preservatives, putty, and some powder products.
In 1999, the West Bank Road factory was expanded threefold as the Larsen brand diversified into manufacturing new building products. The company continued to grow and with the opening of the Larsen state-of-the-art powder plant in 2008, the production capacity also grew significantly and triggered entry into the GB market.
Today, the company operates with a robust presence across Ireland and the UK, with sales divisions strategically located to support a growing customer base. As a family-run business, Larsen has steadily expanded its product portfolio, providing cutting-edge solutions to meet the diverse needs of the professional, whether it be architect, contractor, builder, tiler or DIYer.
Larsen’s dedication to innovation remains at the heart of the company’s operations. With significant investment in its on-site research and development (R&D) and quality control (QC) labs at the Belfast headquarters, Larsen continues to pioneer new products, utilising advanced experimental methods and equipment to develop tailor-made solutions that address the unique requirements of end users. This commitment to R&D ensures that Larsen stays at the forefront of the industry, providing high-quality products that enhance the performance and reliability of construction, tiling, flooring and Streetscape paving projects across Ireland and Great Britain.
Expanding for the Future
With multiple sales divisions in a state of growth, Larsen is making strides in establishing a solid brand position within each market. For the builders’ merchant division, Larsen is stepping up its in-store merchandising presence and enhancing on-shelf brand image. Across the tiling and flooring sector, the team are harnessing their extensive technical product expertise to advise on the best products required for various installations, from airports and shopping centres to swimming pools and even helicopter showrooms!

When it comes to the silos and bulk admixtures side of the business, Larsen can building materials direct to site either via pallet, silo, or tanker.
Responsible for creating some of the most iconic landscape projects, Larsen Streetscape Eco BS 7533 paving mortar system delivers not only trusted, high performance priming, bedding and jointing materials, but also offers eco reduced carbon benefits.

Sustainability at the Core
Looking ahead, Larsen is committed to sustainability, with plans to further introduce environmentally conscious practices into its operations and manufacturing processes. In 2025, Environmental Product Declarations (EPDs) will be made available, and the manufacturing team will also be working towards achieving ISO 45001 Health & Safety Management certification.
Both Larsen factories, which are based in the Belfast docklands, are already powered by green energy, and operate with very little wastage due to computer-controlled production. The company also continues to offer bulk deliveries direct to site via the Larsen tanker, thus reducing the need for any packaging.
Celebrating 50 Years of Success
The 50th anniversary is a testament to the enduring dedication of Larsen’s employees, many of whom have been with the company for 20, 30, or even 40 years. These long-service employees have played an integral role in preserving the company’s product knowledge, technical expertise, and professional reputation, ensuring that Larsen continues to thrive as a trusted name in the construction industry for years to come.
As the company celebrates this major milestone, the Larsen team have also been looking towards the future. Significant upgrades have been made to the Belfast premises through the enhancement of the office, warehouse, factory, and canteen spaces to create a modern and comfortable working environment. With a newly designed conference room, Larsen’s headquarters in the heart of the Belfast docklands now stands as an inviting space for employees, customers, suppliers, and visitors alike.
In May 2025, the team celebrated this incredible milestone alongside customers, suppliers, and staff, all of which have played a key role in making Larsen the trusted, professional brand that it is today. With guests attending from all over Ireland and the UK, the event kicked off with a light breakfast and brand presentation from Larsen’s Managing Director.
Throughout the day, guests were treated to guided tours of both manufacturing sites, and never went hungry or thirsty with the pizza van, buffet lunch and plenty of refreshments available. The afternoon of celebrations came to an end with a Belfast city sightseeing bus tour, allowing guests to take in all the iconic landmarks where Larsen building products have been used.
Looking Towards the Future
Larsen is excited to embrace the next chapter of its journey with a key focus on sustainability, product innovation, and expanding within the construction sector both domestic and further afield. The addition of a new marketing team means that the Larsen brand presence is growing day by day, and marketing support is now available to customers across all divisions. With the creation of new point of sale materials, brochures, social media assets, product application videos, revamped packaging, and a new website underway, Larsen feels confident that its future looks bright!
