Substratum knows Walkway Management from the Ground Up

What We Do For You

Expert Witness for Walkway Safety – whether you are the Plaintiff or Defendant. A standards-based walkway audit conducted by a qualified person can quickly identify and quantify the elements related to a walkway safety issue. For single site incidents like a slip and fall a walkway safety audit and report can usually be completed in one day.

We have over 15 years of developing and evaluating walkway safety programs for all Commercial segments (Foodservice, Retail, Hospitality, Education, Healthcare, Office). Our expertise includes domain knowledge in substrate selection, tools, chemistry, process, training, and oversight required to minimize the risk and cost of slips and falls.

You need an expert who understands the industry standards from a practical perspective and uses physics-based, scientific principles to evaluate safety issues. This can be a key determinate in the outcome of a case.

General Underwriting Loss Control Surveys – Collect the information you require for informed decisions.

Opinion – When an accident happens we can quickly review the known facts of the situation and provide an opinion.

Written Opinion – We complete an onsite, standards-based, walkway safety audit that identifies dangerous conditions in the facility, evaluates the processes in place against the expected level of care, and identifies a proximate cause of the accident.

Deposition and Trial – We are available for further litigation support as required to defend the opinion from our investigation.
