SCRIM® Surveys

Highway safety, asset performance, and cost-efficiency all depend on reliable insight.

WDM’s SCRIM® surveys deliver high-precision friction data across entire road networks-supporting smarter decisions, earlier interventions, and safer outcomes.

Optimise Your Network with Targeted Friction Data

WDM took the idea of a sideway force friction measuring principle over 50 years ago and developed technology to produce reliable and repeatable results, leading to the design of SCRIM® mechanisms manufactured and mounted onto SCRIM® survey vehicles built by WDM.

We’ve been advancing the technology ever since.  As the most widely adopted continuous friction measurement system worldwide, SCRIM® survey vehicles and equipment set the standard for repeatability, accuracy, and impact.

By continuously measuring surface friction and capturing geolocated texture and condition data, SCRIM® surveys empower you to monitor risk, inform policy, and invest with confidence.

 

  • Prevent Wet-Weather Incidents

    Identify low-friction zones before they contribute to collisions, enabling proactive interventions that keep all road users safer.

  • Optimise Maintenance Spend

    Use accurate, real-time data to prioritise resurfacing and treatments-ensuring budgets are focused where they’ll have the most impact.

  • Support Regulatory Compliance

    SCRIM® helps meet national and international skid resistance standards, supporting evidence-based safety policies and audits.

  • Extend Asset Life

    Targeted friction data enables timely maintenance, slowing deterioration and increasing the lifespan of high-risk sections of road.

Why WDM?

  • 50+ years of global leadership
  • Certified to national and international standards
  • Trusted by national road agencies, consultants, and asset managers
  • Supported by in-house engineering, R&D, and survey operations
