What Are Concrete Formliners?
The definitive guide to understanding concrete formliners, their applications, and how they transform ordinary concrete into architectural masterpieces.
Quick Answer
Concrete formliners are reusable or single-use textured molds placed inside concrete forms to imprint patterns, stone textures, wood grain, geometric designs, or custom artwork onto poured concrete surfaces. Instead of leaving a flat, smooth finish, formliners shape the concrete during casting to achieve architectural, decorative, or structural design intent.
Formliners are widely used in cast-in-place, precast, retaining walls, bridge abutments, DOT infrastructure, tunnels, and architectural façades. They give architects full creative control over depth, scale, and realism while allowing contractors to install them easily using standard forming systems.
Customrock specializes in high-performance formliners manufactured in the USA, offering urethane elastomer, ABS plastic, and single-use Styro® options, along with fully custom designs. For over 50 years, Customrock has produced industry-leading form textures for major architectural and civil engineering projects across the country.
What Concrete Formliners Mean
Concrete formliners are engineered liners used to create textured or patterned surfaces on concrete. They fit inside the formwork and become the interface between wet concrete and the final exposed surface.
Core Characteristics
- Create consistent, repeatable textures
- Support complex artistic or structural designs
- Work with standard steel, wood, and modular concrete forms
- Available in multiple durability grades for different project sizes and budgets
Common Materials
- Urethane Elastomer – Flexible, highly durable, ideal for multiple reuses
- ABS Plastic – Rigid, economical, suitable for medium repetition
- Single-Use Foam (Styro®) – Cost-effective for one-time pours, DOT projects, or large wall areas
Why Concrete Formliners Matter
Architects and engineers rely on formliners to transform structural concrete into an expressive design element without complex post-processing.
For Architects
- Expands design possibilities
- Enables custom branding, murals, or thematic designs
- Provides precise control over texture depth and scale
For Contractors
- Fast installation
- Works with existing forming methods
- Reduces labor compared to hand-carved or post-applied finishes
For DOT & Infrastructure
- Enhances bridges, retaining walls, and sound barriers
- Supports naturalistic designs to blend into local environments
- Meets DOT durability and repeat-use requirements
How Concrete Formliners Work
A simple 5-step process transforms your design vision into stunning textured concrete.
Design Selection or Custom Creation
Choose a pattern from our texture library or develop a unique custom form tailored to your project vision.
Formliner Manufacturing
Customrock fabricates the liner using urethane, ABS, or foam based on project requirements and reuse goals.
Installation Inside Formwork
Liners are attached to the form with screws, adhesives, or backing systems—compatible with standard forming methods.
Concrete Placement
Wet concrete is poured against the liner surface, filling every detail of the texture pattern.
Form Removal
Once cured, the liner is stripped to reveal a detailed architectural finish ready for staining or sealing if desired.
