    Teretek Injection Technology

    Advanced Solutions for Culvert Infrastructure Challenges

    Compromised culverts can negatively impact the structures they support and the performance of the stormwater systems they are connected to.

    Culverts beneath road and rail infrastructure are often subject to settlement, water ingress, and soil instability, leading to safety concerns and costly disruptions. Teretek® resin injection technology provides a fast, targeted, and non-invasive solution to restore stability and extend culvert service life.

    How Teretek® Works

    Teretek® is injected directly into the ground or voids around culverts, where it expands to strengthen weak soils, seal leaking joints, and lift settled structures back to level. This precision injection method addresses both the underlying causes and visible effects of culvert deterioration.

    By addressing soil weakness, subsidence, and leakage at their source, Teretek® helps infrastructure owners maintain safe, reliable culverts while avoiding the downtime, expense, and disruption of traditional repair methods.
