When an architect specifies a textured concrete finish, the apparent cost often leads to it being simplified, redesigned, or removed from the project altogether. That reaction is understandable as, viewed in isolation, the cost per square metre of the liner required to create the finish can make it seem very expensive.
However, form liners are designed to be reused. If a liner costing £350 per square metre, for example, is used 10 times, the cost effectively falls to around £35 per square metre. If the design allows it to be used 100 times, the cost drops to just £3.50 per square metre. Suddenly the economics look very different.
When contractors resort to workarounds
Something that does genuinely make architectural finishes more expensive is when the formwork is already decided and the contractor has to source the liner separately. Panel sizes might not align with the intended pattern, reuse opportunities may be missed, and details that looked straightforward on a drawing become more difficult to deliver in practice. In some cases, contractors end up trying to recreate the same effect manually using timber strips fixed to the formwork.
This might look like a saving on paper, but manual approaches increase labour, make repeatability harder, and lead to remedial work if the finish is damaged or inconsistent. What initially appears to be a cheaper option can quickly become more expensive once time, rework, and finish quality are fully considered.
The alternative is rarely a choice between an architectural finish and spending nothing at all. More often, it is a choice between a purpose-designed solution and a labour-intensive workaround.
Designing the finish and formwork together
This is where a joined-up approach starts to make a difference. Rather than treating the liner as a later-stage addition, we can consider the architectural finish and formwork strategy together from the start. For contractors, that means having access to both formwork and architectural liner expertise from a single conversation with the PERI team.
Over the last couple of years, we have been working closely with RECKLI to provide this one-stop-shop for our customers. It’s more convenient to deal with one supplier for both the formwork and liners and once liner reuse, formwork layout, sequencing, and installation are considered together, opportunities often emerge that are difficult to see when each element is viewed in isolation.
That reduces the risk of discovering too late that the finish, formwork, and programme don’t quite line up. Contractors gain certainty around what needs to be ordered, how many times it can be reused, and how the finished will be achieved, as well as the certainty that an architectural idea can be judged on its true delivery cost, rather than the first figure that appears on a quotation.
The cost of compromise
Architectural concrete will not be right for every structure. Some projects will always choose the simplest possible finish, and that is fine. But many projects rule out more interesting finishes before the practical options have been fully explored.
That matters because concrete is not always hidden behind another material. On bridges, public buildings, infrastructure projects and commercial developments, concrete is often part of what people see, touch and remember. The finish can help a structure sit more naturally in its surroundings, create visual identity, or turn a functional surface into something more considered.
So the next time an architectural concrete finish appears too expensive to justify, it may be worth asking a different question. Is the finish really the problem? Or has the project simply not yet been designed to make the most of it? Your usual PERI representative will help you find the answer.
“Too often, people see the headline cost of a form liner and assume the finish is unaffordable. The reality is that once reuse rates, formwork design, and installation are considered together, the economics can look very different. That is why the earlier contractors involve PERI, the more options they usually have.”

“Through our partnership, contractors can get both their formwork and liners directly from PERI, making it easier to evaluate design ambitions, reuse opportunities, and delivery requirements in one place. The result is a more straightforward process and greater confidence that the selected solution will achieve the desired result efficiently and cost effectively.”
