Silicone and polyurethane moulds, formliners and pattern tooling for precast concrete, GRC, architectural cladding, cast stone and heritage restoration. Specified around your mix and your strike sequence, not around a catalogue texture.
Who we are

A silicone or polyurethane mould for concrete has to survive release agent, alkaline pours, being hosed off, being stacked, and being rushed back onto the bed. We build tooling around your mix and your strike sequence, not around what a catalogue said the texture should be.
Four shapes of work
Four kinds of tooling come through this division — surface formliners, three-dimensional unit moulds, thin-shell GRC tooling, and one-off replacements for heritage jobs.
Surface tooling — wood grain, stone, brick, custom relief. Silicone or polyurethane, sized to your bed and your panel joints.
Three-dimensional single-panel tools. Balustrades, copings, capstones, bench ends, bollards, keystones.
Thin-shell moulds for glass-reinforced concrete cladding, cornices and lightweight architectural elements.
One-off silicone rebuilding a lost feature on a listed elevation. Repeated exactly, from a single surviving sample.

Where our tooling goes
Different jobs, but the same four questions underneath: what surface, what mix, how many pours, how it's handled.
Formliners and unit moulds for panel yards running structural and architectural precast.
Thin-shell tooling for cornices, spandrels and lightweight façade panels.
Sharp-edged moulds for keystones, cills, quoins and dressed-stone reproductions.
Rebuilding a lost detail from a single surviving section, in situ or on the bench.
Bench ends, planters, bollards, paving relief, public realm bespoke.
Small-format decorative pieces, garden ornament, bespoke retail props.
How we work
Every enquiry gets a human reply the same day it lands. If we need longer to price it properly, we'll tell you why and when to expect the number.
Two lines on the quote. What the tool costs to build, and what each part costs once it's running. Nothing rolled up to look cheap on order one.
The mould leaves with a document that says what it's made of, what it's rated to, and what it isn't for. Fine to hand straight to an architect.
Design and development in the UK. Manufacturing capability in the UK, with some higher volume placed with partners where that's the right answer.
One engineer runs your job. Not a queue, not a portal-only conversation. You have their name and their direct line.
A single formliner or one-off restoration mould is a real order. We won't push you into volume tooling before it's the right economics.
From the workshop
Every tool starts as a pattern we can put in front of you. Silicone or polyurethane is poured against it, cased for your bed, and checked before it leaves.
Then it goes to work in a yard like yours. The one-stop shop page explains the whole chain, and our quality page explains the paperwork that travels with it.

The group
TCI Construction is one of four divisions in TCI Group. Concrete, cast stone, GRC and restoration work come through here. Silicone moulds for other applications go to the right specialist team.

FAQs
Yes. We spec silicones and polyurethanes that hold up to portland cement pH without degrading. We'll ask about your mix so the right grade goes on the bed.
Yes. Send us a photograph, a squeeze, or in listed cases a section of the original. We'll rebuild it as a mould that can be run repeatedly.
Larger than a standard bed. Formliners get spliced routinely; we'll design the seams to fall where the panel joint already is, so they don't read on the finished face.
Depends on mix, release, and how well it's handled. Well-treated silicone formliners on a normal precast programme reliably run into three figures. Polyurethane formliners often further, on the right mixes.
Polyurethane is the workhorse for concrete — tougher, longer-lived on straightforward relief. Silicone earns its keep on fine detail and undercuts. We'll say which one your job needs, and why.

One photograph tells us what surface you're chasing, and one line about the mix tells us what silicone or polyurethane will survive it.
