PETRA — Engineering expertise, expressed visually

Logo redesign and brand applications

PETRA specialises in large-scale concrete cutting, drilling and repair. The project began with a request to redesign its existing logo. I built the concept around the company’s services and how they could be expressed through a single symbol connected to its name.

Before

After

One symbol connects the company’s expertise to the letter P

The idea behind the design

The logo takes the form of the letter P, combining visual references to the stages of working with concrete: scanning, cutting and repair.

The upper waves represent scanning concrete with modern equipment to understand its internal condition before cutting or drilling. The circular opening refers to core drilling and circular cutting, while the three flowing paths express precision in cutting.

In the area inspired by concrete’s colour and texture, cracks and their treatment represent epoxy injection repair. A strip-like element refers to reinforcement with carbon fibre.

From logo to application

After designing the logo, my work extended to business cards, company applications and its profile, carrying the new design across these materials to create a consistent visual presence.

Business cards / Bringing the concept into use

A brand present in every detail

PETRA letterhead, envelopes and business cards — Stationery and correspondence

PETRA branding on safety clothing and equipment — Workwear and safety equipment

PETRA identity on team uniforms — The identity on site with the team

Cutting and drilling equipment

PETRA company signage — Signage and brand presence

Machine branding — From concept to print artwork

I developed the identity’s appearance on the machines and prepared panel artwork, logo variations and production notes. These files were sent to China for printing. The images here show the concept and production artwork, rather than documentation of the finished machines.

Content that explains the specialism

The identity also extends to social posts presenting structural solutions and explaining the stages of studying a project and defining a solution. The designs combine work imagery with technical information in a visual style connected to PETRA.

From idea to execution — Project study stages

Company profile — Bringing the story together

The identity extends into the company profile, from its opening cover to the closing contact page.

Closing page / Contact information

The logo became a starting point that connects PETRA’s name to its specialism, giving the details of its engineering work a distinct visual expression.
