Three decades making fibreglass. Now we repair it.
GemRock has engineered and manufactured fibreglass in-house since 1993. It makes fibreglass for defence, industry and the home. Today that experience is focused on repair: industrial plant, buildings, boats and vehicles.
We know how it's made. That's how we know how to mend it.
GemRock was founded in 1993 to engineer and manufacture fibreglass in-house. Over three decades that has meant cooling towers and components for industry, work for defence, and fibreglass doors for the home.
Making fibreglass teaches you how it behaves: how a laminate is built up, which resin suits which job, where a moulding carries its load — and how it fails when something goes wrong.
That is the knowledge a repair depends on, so the business now leads with repair: damaged fibreglass and GRP in four sectors, on site or in our workshop. We still manufacture. See what we make

How we approach a repair.
Assess before quoting
What the item is, how it is built and how far the damage goes all shape a repair, so that comes before a price.
Plain facts over promises
Our repair pages explain what a repair involves and what finish to expect. You won't find "good as new" claims here.
Repair or replace
Not everything is worth repairing. Where the structure underneath is no longer sound, replacement is usually the better answer — and our repair pages say when.
Repair first. Manufacturing alongside.
