Founded in the early 1950s, Intrusion Prepakt introduced pressure grouted pile systems that would go on to shape the deep foundations industry.
Intrusion Prepakt Foundations of Innovation since 1951.
About us
A Legacy of Geotechnical Innovation
Our patented “Pakt-In-Place” system was a breakthrough in piling techniques and remains the foundation of many modern augercast systems. Today, we continue this legacy by delivering technically advanced foundation systems in diverse geological settings. Intrusion Prepakt is a pioneer in deep foundation solutions, credited with developing the original augered cast-in-place (ACIP) piling method. From residential stabilization to large-scale industrial projects, we provide expert-driven, engineered solutions backed by decades of geotechnical innovation.
- Engineered Foundation Solutions for Every Ground Condition
- Trusted Across Industries, Soils, and Site Challenges
- Experts in Grout Bags and Concrete Mattress Protection
- Invisible reinforcement beneath your structure’s foundation.
Our Services
Experience That Sets the Concrete
Underwater Concrete
Expert placement of concrete below waterlines using specialized methods such as tremie pipes and grout bags. Our underwater concreting solutions provide solid, long-lasting foundations and repairs without the need for dewatering.
Bulk Filling of Cavities & Tremie Concrete
We use tremie systems to place concrete in deep or submerged conditions. This method ensures quality and uniform placement in foundations, caissons, and bridge piers while minimizing segregation and washout.
Concrete Mattresses
Articulated or continuous mattresses used to stabilize banks, prevent erosion, and support revetment projects. Can include filter fabric layers, steel cable reinforcement, and custom contours.
Permeation Grouting & Pressure Grouting
We inject low-viscosity grouts to strengthen soils, reduce permeability, and stabilize structures. This non-invasive technique is ideal for controlling water ingress, preparing foundations, and sealing tunnel linings.
