The manufacturing industry is a key employer in Donegal and one company punching above its weight for the past two decades is Diorite Solid Surface Technology. Established in November 1996, the business benefits from a strong and experienced core team who have been with the company since its inception – this has allowed Diorite to expand over the years and build a solid customer base across Ireland and the UK.

From its base in Buncrana, Diorite manufactures, supplies and fits a seamless, non-porous solid surface material to both the commercial and domestic markets. The company is the preferred installer for leading brands including Technistone Quartz, Dupont Corian, LG HI Macs, Krion, Samsung Staron, Avonite, Surrell, Durat, Hanex, Durasein, and Tristone.
Local Enterprise Office Donegal Stories
Diorite manufactures, supplies and fits two main types of materials: solid surface and engineered stone such as quartz and granite. We supply both the commercial and domestic markets, and our main line of products includes kitchen worktops, vanity units, bar and restaurant countertops, laboratory bench tops, bath and shower surrounds, reception desks, and table tops. Along with aesthetic appeal, our material is targeted at clients with health and safety, hygiene and durability requirements and we pride ourselves on taking innovative design, interior elegance and beauty to a whole new level.
