What Larsen Building Products does

Larsen Building Products is a family-owned manufacturer of construction chemicals and building products headquartered in Belfast Harbour Estate, Northern Ireland, operating from a 1984-established HQ site with an additional 50-metre tower facility on McCaughey Road and a 7-acre manufacturing site acquired in Derbyshire, England in 2022. The business was founded in 1975 in Antrim initially selling concrete admixtures, then diversified through the 1990s into liquid building chemicals, epoxy resins, wood preservatives, putty and powder products, before scaling into a multi-category building products platform organised into Admixtures (Chemcrete brand), Builders' Merchants, Flooring, Highways, Streetscape ECO, Tiling (Fibreflex™ and Larsen Pro), Precast, and Speciality divisions, with sub-brands including FJM Eco, Quickmix, FTG, LLC, SLC, and Fusion XT. Core technology centres on chemical formulations such as Advanced HydroGel Technology in tile adhesives (S1-rated, microfibre-reinforced), BS 7533-compliant paving systems using GGBS-blended eco-reduced carbon mortars (49.5 MPa compressive, 8.6 MPa flexural), HAPAS-approved ironwork installation mortars, and self-levelling/latex levelling compounds; operations are ISO 9001 and ISO 14001 certified and the Belfast site runs on Power NI renewable electricity.
