OUR HISTORY

Larsen begins
Larsen started in 1975 in Antrim, Northern Ireland. Initially selling admixtures to various concrete plants throughout Northern Ireland.
West Bank Road
West Bank Road
The company later moved to Belfast Harbour Estate in 1984, to be the first building established on the newly reclaimed Industrial Estate on West Bank Road.
Continued expansion
The factory was extended three times during the 90's as the company diversified into manufacturing products. The range of products expanded from concrete admixtures into liquid building chemicals, epoxy resins, wood preservatives, putty and some powder products.

A new market

McCaughey Road Powder Plant
The building boom
The building boom in Ireland during the early 2000's encouraged Larsen to build a state of the art powder plant opened in 2008, increasing capacity more than 10 fold and triggering an entry into the GB market with a sales office established near Birmingham.
45 years in business
2020 marked our 45th year in business. These years have seen Larsen Building Products go from strength to strength. Larsen have now established itself as the largest manufacturer of builders merchants products in all of Ireland.
Future Plans
Looking to the future
As sales continue to grow, with almost one third of our total sales now in Great Britain, a 7 acre manufacturing site was acquired in Derbyshire, England, to build a new factory. Construction is due to start later in 2022.
