GRC relief tooling for decorative and heritage elements.

Overview

GRC relief tooling, in plain terms.

GRC is a popular route for heritage and decorative work because it's light and can be hung from a modern frame. The relief is what the eye sees.

Silicone is usually right here: it captures fine detail and releases thin shells without violence.

What sets it apart

Four things that define this route.

01

Cornices and string courses

Long profiled runs in lightweight sections.

02

Spandrels and panels

Decorative relief panels for new-build and restoration.

03

Heritage reinstatement

GRC copies of lost features from a survivor.

04

Undercut detail

Silicone flexes past it.

How we build it

From pattern to released tool.

We mould from a heritage survivor or a new pattern, and build a rigid case to hold the silicone in shape under spraying.

Section lengths are agreed with your team for handling and joint positions.

The honest bit

What to know before you commit.

GRC relief is still a thin shell. Very deep undercut may need a split mould or a design tweak; we'll say which.

The silicone holds the detail, the rigid case keeps it true, and the split line lets the part come out without tearing.

FAQs

Questions we hear about this.

Can the same mould cast cast stone too?

Sometimes, but GRC and semi-dry cast stone usually want different tools.

How long can a run be?

Long enough to handle safely, with joints at planned positions.
