In today’s world of complex infrastructure and demanding environmental standards, off-the-shelf solutions often fall short. That’s why Fiberglass Tank Solutions is redefining underground storage with tanks that are 100% custom-built to meet each project’s exact needs. From the tank’s diameter and length to the resin composition and internal accessories, every underground tank we manufacture is tailored with precision, performance, and longevity in mind.
When your project requires specific storage capacities, high chemical resistance, unique installation conditions, or demanding regulatory compliance, cookie-cutter tanks won’t cut it. Here’s why a custom-built underground tank from FGT Solutions is the best choice and, in some cases, the only one for engineers, contractors, municipalities, and commercial property owners. FGT has been manufacturing custom-built tanks for over a decade, and our quality control is second to none.
Precision Engineering: Custom Diameter and Length for Every Project
Every underground tank we are commissioned to build starts with your specifications. Unlike pre-cast or fixed-mold options, FGT tanks are custom-fabricated in diameter and length to match your exact storage volume requirements.
- Does your project require a low-profile tank with a wide diameter to meet site restrictions?
- Do you need a longer, narrower tank to fit within a specific utility corridor?
- Designing a multi-tank system for phased storage or chemical separation?
We make it possible. With FGT Solutions, you’re not working around the tank, the tank is built around your project.
Specialized Resin Formulations: Built for Your Environment
Storage conditions vary greatly, and so do the materials stored. FGT offers advanced custom resin formulations to meet the challenges of:
- Highly acidic or alkaline contents (extreme pH levels)
- Elevated temperatures up to 200°F
- Chemical processing waste, oils, leachate, or industrial byproducts
- Aggressive soil or groundwater
Our fiberglass-reinforced plastic (FRP) tanks are crafted with resins selected specifically for your application. They offer the best chemical resistance and long-term structural integrity in the industry.
Factory-Installed Features: Ready for Anything
Every tank from FGT Solutions has a wide array of factory-installed fittings and modifications, so you receive a complete system, not a blank shell. Standard and custom features include:
- Access risers and manways to grade for easy inspection and maintenance
- Internal piping and baffles for flow control, compartmentalization, and mixing
- Reinforced ports for mixers, pumps, sensors, and heating elements
- Pump-out access, fill lines, and venting systems
All factory-installed components are built to spec, leak-tested, and aligned with your operating requirements. This results in faster installations and fewer field modifications, reducing project delays and labor costs.
Lightweight, Yet Built to Last
Despite their incredible strength and chemical resistance, FGT underground FRP tanks are lightweight, making them easier and less costly to transport and install than traditional steel or concrete tanks.
Benefits of FRP include:
- Corrosion resistance in even the harshest environments
- No rusting, rotting, or internal liner degradation
- Easier to handle with smaller equipment and fewer crew members
These qualities make FRP tanks a preferred choice for and of the following applications:
- Water and wastewater treatment facilities
- Industrial processing plants
- Chemical storage depots
- Environmental remediation projects
Watertight and 100% Testable
FGT custom underground tanks are not only designed to last, but also manufactured to be 100% watertight and testable. Each tank is subjected to rigorous quality control inspections, including:
- Hydrostatic pressure testing for seam integrity
- Vacuum testing of risers and ports
- Visual and dimensional checks for all customized fittings
Our tanks meet or exceed national testing standards and can be tested and certified in the field to satisfy municipal and environmental agency requirements.
Built with Inspection in Mind: Solar-Grade Report Ready
Every FGT custom tank is built to withstand and excel under third-party scrutiny, including inspections conducted under stringent reporting requirements like those from Solar or other high-regulatory sectors.
Any issues noted in an inspection report, such as:
- Imperfect surface finishes
- Port alignment
- Installation interface errors
…can be immediately addressed with our factory-based quality team. Our tanks are designed for real-world conditions and ease of verification, ensuring you stay compliant and on schedule.
