FRP Foot Support Component for Extending a Ø2200mm Modular Tank

TankSmith supplies the FRP foot support component used to extend a ø2200mm modular bolted tank upward, adding capacity without replacing the whole system. The component is engineered to match your tank's existing panel specification, sourced through the same ISO 9001 certified partner factories used for new builds, and covered under TankSmith's 3-year FRP panel warranty over a 20 to 25-year design life.

What the FRP Foot Component Does

On a modular bolted FRP tank, the base course of panels sits on a foot or leg support that carries the structure's load and keeps the tank level on its foundation. When a tank is extended upward with an additional ring of panels to increase capacity, that original foot support has to be lengthened or swapped for a taller matched component so the extended structure keeps the same footprint, the same bolt-line alignment, and the same load path down to the foundation. A mismatched or improvised foot component is one of the most common reasons a tank extension fails inspection or develops leaks at the panel joints. TankSmith supplies the foot component as a matched part of the extension, engineered against the exact panel specification of the tank being extended (including a ø2200mm diameter tank), so the added height integrates into the original structure instead of sitting on top of it as a separate, weaker assembly. Because the component has to match the original tank's bolt pattern, panel radius, and material (FRP, GRP, HDG steel, or stainless steel), TankSmith assesses the existing installation first, sources the matched component through the same ISO 9001 certified partner factories used for new tank builds, and installs it as part of one contracted scope rather than as a standalone spare part sold without a site assessment.

When You Need a Tank Extension Foot Component

Tank extensions come up when demand for stored water outgrows the original design capacity. A commercial laundry operation that scales up linen throughput per day needs more reserve than its tank was sized for at installation. A hotel or resort adding rooms increases both potable draw and booster pump demand on the same rooftop tank. A hospital or clinic may need to add a fire reserve to meet code after the facility expands, and a condominium or high-rise adding units puts extra load on a rooftop tank that was sized for the original unit count. A warehouse or manufacturing facility scaling up process water use faces the same problem, and estates inside PEZA, SBMA, Clark, or other freeport zones sometimes take on additional tenants that share a single water system. In every one of these cases, replacing the whole tank costs more, takes longer, and is harder to schedule around an operating facility than extending the existing one. A matched FRP foot component lets the extension carry the added height safely on the original footprint, which is why TankSmith treats it as part of a retrofit assessment rather than a generic catalog part.

Material and Certification

TankSmith works across four bolted panel materials: FRP (fiberglass reinforced plastic), GRP/SMC (sheet moulded compound), HDG (hot-dip galvanized) steel, and stainless steel 304/316. The extension component is matched to whichever material the existing tank uses, since mixing incompatible materials at a structural joint is a common cause of corrosion or seal failure. Where the extended tank stores potable water, TankSmith uses WRAS-certified panels rated for potable water up to 65°C and NSF-compliant liners, the same standard applied to new tank builds. Panels are produced under an ISO 9001 manufacturer quality management system and are TUV SUD tested. The extension work is covered under TankSmith's 3-year FRP panel warranty, and the tank's overall design life remains 20 to 25 years after the extension is installed, provided the added component matches the original specification and is installed by the same team that assessed the site.

How TankSmith Supplies and Installs the Component

TankSmith runs tank extensions the same way it runs new installs: one team is accountable for supply, installation, and commissioning under a single contract, so there is no gap between the company that sourced the component and the crew that bolts it on. The process starts with a site assessment of the existing tank (diameter, panel material, current foot or leg configuration, and the reason for the extension), followed by sourcing the matched component, then scheduling the install around the facility's operating hours. Typical installs for TankSmith's tank systems run 5 to 14 days depending on capacity and how ready the civil works and foundation are on site, and an extension retrofit generally falls at the shorter end of that range since the foundation and base structure already exist. TankSmith covers NCR, the rest of Luzon, Visayas, and Mindanao, including sites inside PEZA, SBMA, and Clark freeport zones, so an extension on a ø2200mm tank can be scheduled and completed without shipping a generic part and leaving the fit-up to an outside crew.

Tank Diameters and Capacities This Applies To

TankSmith's modular bolted panel systems cover 1,000 liters to 500,000 liters per tank, and the panel-and-foot design scales across that range rather than being fixed to one diameter. A ø2200mm tank sits toward the smaller end of that capacity band, which is common for rooftop retrofits on hotels, condominiums, and clinics where headroom and access are tight. Because the panels are modular, extending a ø2200mm tank upward by adding a course, and matching the foot support to the new height, is a smaller-scope version of the same engineering TankSmith applies to a 500,000-liter industrial system. The same four materials (FRP, GRP/SMC, HDG steel, stainless steel 304/316) and the same WRAS, NSF, ISO 9001, and TUV SUD standards apply regardless of the tank's diameter or where it sits in that capacity range. TankSmith assesses each extension against the specific diameter and panel batch already on site rather than applying a one-size component across different tank models, since a foot support sized for one diameter will not carry the load path correctly on another.

Who Uses This Component

The tank extension foot component comes up most often in verticals where water demand grows faster than the building's original design: commercial laundries sizing reserve to linen throughput per day, hotels and resorts adding rooftop capacity alongside booster pump upgrades, hospitals and clinics adding fire reserve to stay code-compliant, food manufacturing sites that need WRAS-compliant potable storage, warehouses and manufacturing plants scaling process water, and condominiums or high-rises retrofitting a rooftop tank with tight access. Industrial estates inside SBMA, Clark, Cavite, and Batangas also see this scenario when a tenant's water use outgrows the original system installed at move-in. In each case, the underlying problem is the same: the tank's diameter and foot configuration were sized for a smaller demand, and extending the structure with a matched component is faster and less disruptive to an operating facility than a full tank replacement.

Frequently Asked Questions

What is an FRP foot component used for on a tank extension?

It is the support piece at the base of a modular bolted tank that carries the structure's load into the foundation. When a tank is extended upward with an extra course of panels to add capacity, the original foot has to be lengthened or replaced with a taller matched component so the extended tank keeps the same footprint and bolt-line alignment as the original structure. TankSmith engineers this component against the exact panel specification of the tank being extended, including ø2200mm diameter tanks, and installs it as part of a single contracted retrofit rather than selling it as a generic spare part.

Can TankSmith supply just the foot component, or does it have to be a full retrofit?

TankSmith assesses the existing tank first, since the foot component has to match the tank's diameter, bolt pattern, and panel material exactly to carry the load correctly. Because of that, TankSmith supplies the component as part of a contracted retrofit scope, with the same team handling supply, installation, and commissioning under one contract. This avoids the fit-up problems that come from installing a generic part sourced separately from the original tank's specification.

What tank diameters and capacities does TankSmith's extension work cover?

TankSmith's modular bolted panel systems run from 1,000 liters to 500,000 liters per tank. A ø2200mm tank sits toward the smaller end of that range, typical of rooftop retrofits on hotels, condominiums, and clinics. The same panel materials, FRP, GRP/SMC, HDG steel, and stainless steel 304/316, and the same foot-and-panel engineering apply whether the tank being extended is a small rooftop unit or a large industrial system.

Is the extended tank still safe for potable water?

Yes, provided the extension uses WRAS-certified panels rated for potable water up to 65°C and NSF-compliant liners, the same standard TankSmith applies to new tank builds. Panels are produced under an ISO 9001 manufacturer quality management system and TUV SUD tested. The extension is covered under TankSmith's 3-year FRP panel warranty, and the tank's overall design life stays at 20 to 25 years after the extension, provided the added component matches the original specification.

How long does a tank extension retrofit take?

TankSmith's tank installs typically run 5 to 14 days depending on capacity and how ready the site's civil works and foundation are. An extension retrofit on an existing tank, such as a ø2200mm unit getting a foot component and an added panel course, generally falls at the shorter end of that range since the foundation and base structure are already in place and do not need to be built from scratch.

Does TankSmith handle tank extensions outside Metro Manila?

Yes. TankSmith covers NCR, the rest of Luzon, Visayas, and Mindanao, including sites inside PEZA, SBMA, and Clark freeport zones. A tank extension on a ø2200mm tank or any other size in TankSmith's 1,000-liter to 500,000-liter range can be assessed and scheduled nationwide, with one team handling the supply, installation, and commissioning of the matched foot component under a single contract.
