WHEN THE BASE OUTLASTS THE MAINTENANCE CYCLE

POLYMER BLOCK FOUNDATIONS

A chloride-rich processing facility was rebuilding centrifuge foundations on every major maintenance cycle — an expensive, disruptive pattern driven by reinforced concrete that simply couldn't survive the environment. MIC replaced it with a polymer block system that hasn't needed a single touchup in three years.

THE SITUATION

An industrial processing facility operating in a chloride-rich chemical environment was experiencing recurring degradation of its steel-reinforced concrete centrifuge foundations. The facility operates four centrifuges on an elevated deck, and each major maintenance event requires crane mobilization for isolator replacement — a mobilization that runs approximately $100,000 per day.

The traditional concrete foundation system was failing within the maintenance cycle. Chloride-driven corrosion of the embedded steel reinforcement was causing cracking and deterioration that demanded demolition and replacement during every major shutdown — compounding outage duration and cost with each event.

WHY CONVENTIONAL CONCRETE KEPT FAILING

Steel-reinforced concrete is the default foundation material in most industrial environments. In a chloride-rich environment, it becomes a liability. Chloride ions penetrate the concrete matrix, attack the embedded steel reinforcement, and drive expansive corrosion that fractures the surrounding concrete from the inside out. There is no coating or sealant that fully stops this process once chloride exposure is continuous.

  • Chloride-rich environment aggressively attacking embedded steel reinforcement
  • Repeated cracking and deterioration within each maintenance cycle
  • Foundation demolition and replacement required at every major shutdown
  • Crane mobilizations at approximately $100,000/day compounding outage cost
  • Extended shutdown duration due to concrete work during each maintenance event

The core problem: every dollar spent fixing the concrete during shutdown was spent again at the next shutdown. The material selection — not the execution — was creating the cycle.

ELIMINATING THE CORROSION PATHWAY

MIC proposed a fundamentally different approach: replace the concrete with a monolithic polymer block foundation system that contains no ferrous reinforcement at all. Without steel, there is no corrosion pathway. Without a corrosion pathway, the failure cycle stops.

SYSTEM SPECIFICATIONS

  • Monolithic polymer block construction — no ferrous reinforcement
  • Engineered for chemical resistance to chloride exposure
  • Vibration damping properties matched to rotating equipment requirements
  • Dimensional stability under sustained load conditions
  • Designed for compatibility with future isolator replacement procedures

The installation scope included removal of the existing deteriorated concrete foundation, deck and isolator inspection, fabrication and installation of the polymer block system, precision leveling and alignment, and return of all centrifuge equipment to operational service.

THE GREENSHIELD FOUNDATION SYSTEM

The polymer block system installed in this project is built on the BaseTek GreenShield Foundation System — an engineered polymer concrete foundation platform purpose-built for rotating and reciprocating industrial equipment. Unlike traditional steel-reinforced concrete, GreenShield foundations are monolithic polymer structures with no ferrous reinforcement, making them immune to the chloride-driven corrosion cycle that destroyed the previous concrete foundations at this facility.

GreenShield foundations are engineered to deliver compressive strength, chemical resistance, and vibration-damping characteristics that exceed conventional grout systems — all in a single corrosion-proof structure. The system is designed for long service life in the harshest process plant environments: acid environments, marine exposure, chemical spill zones, and anywhere that embedded steel is a long-term liability.

Why GreenShield? Where epoxy grout protects the grout layer, GreenShield eliminates the corrosion pathway entirely — no rebar, no steel, no failure mode driven by chloride or chemical ingress.

THREE YEARS IN — ZERO ISSUES

The polymer block foundations have been in continuous service in a chloride-rich environment for three years. The result is straightforward: the system looks and performs exactly as it did on installation day.

Zero corrosion observed after 3 years of continuous chloride exposure

Zero maintenance required — no touchup, no repairs since installation

Visually unchanged from installation condition — no cracking, no migration

Crane mobilization cost eliminated — no foundation work required during next shutdown
