Gaskets, Seals
& Shims

  • Form in-place gaskets, rebuild sealing faces, and cast precision shims
  • Eliminate soft-foot and maintain alignment
  • Achieve leak-free, properly seated joints
The Challenge

A joint is only as good as the surfaces it seals against. Corroded and pitted flange faces, uneven mounting feet, and improvised shim packs cause chronic leaks, soft-foot, and misalignment that shortens the life of the equipment they support. Re-machining flanges or waiting on custom shims means extended downtime for what is often a simple interface problem.

A Real Rumford Example
Pitting on the clarifier doorway gasket face Before
The Problem
Clarifier Door & Pitted Gasket Face

After repairs to a clarifier at a manufacturer, a doorway was cut out and built up for access. The door needed coating and the gasket face needed sealing — and welding was not an option.

The Solution
Door Coated & Bonded Cold

Belzona 1391 coated the door and Belzona 1121 bonded the plate back on, sealing the gasket face — no welding or hot work.

Outcomes vary by joint condition, service, and access — contact Rumford Industrial Group for a project-specific assessment.

Flange faces, mating surfaces, machine mounting feet, and equipment bases rely on flat, correctly aligned interfaces. Corrosion, erosion, and physical damage destroy that flatness, while loose or corroded shim packs let alignment drift and vibration build.

Belzona materials rebuild damaged sealing faces, form gaskets and seals directly in place, and cast precision shims that fill 100% of the contact area to eliminate soft-foot. Applied cold by Rumford Industrial Group, they restore leak-free joints and stable alignment without machining.

Belzona Solutions for This Application
Shimming & Chocking for Equipment Location
Load-bearing shims and pourable chocking systems used to accurately locate equipment, offering high compressive strength and resistance to crevice, galvanic, and fretting corrosion.
In-Situ Gasket & Seal Formation
Custom-made gaskets and seals of any shape or size formed directly in place, avoiding long shutdowns.
Flange & Pipework Protection
Peelable, resealable encapsulating coatings (with corrosion inhibitor Belzona 8411) that protect flanges and pipework from external moisture, atmospheric, galvanic, and crevice corrosion, along with wear plate bonding at pipe support locations to prevent wear-driven corrosion.
Tank Base Sealing
Sealing corroded or deteriorated tank bases with breathable, solvent-free coatings that block water ingress while allowing trapped moisture to escape.
What Belzona Can Do for Gaskets, Seals & Shims
+
Create gaskets
Form custom gaskets of any shape or size directly in place, with no machining or waiting on cut parts.
+
Bond preformed seals
Cold-bond preformed seals and gaskets securely into position without hot work or fasteners.
+
Tank base sealing
Seal corroded tank base perimeters with breathable coatings that stop water ingress and let trapped moisture escape.
+
Seal entry points
Seal cable, pipe, and duct penetrations to keep moisture and contaminants out of enclosures.
+
Rebuild sliding gate seals
Restore worn sealing faces on sliding gates and penstocks to recover tight shut-off.
+
Repair steam cut flanges
Rebuild flange faces eroded by steam cutting and wire-drawing back to a flat sealing surface.
+
Rebuild compression seal seat areas
Reform damaged seat areas so compression seals load evenly and hold pressure.
+
Restore damaged, distorted, or corroded mating surfaces
Return distorted and pitted mating faces to flatness in situ, without machining the whole component.
+
Create compression shims and facings
Cast irregular load-bearing shims and facings that make 100% contact across the joint.
+
Strengthen corroded flanges
Reinforce and encapsulate weakened flanges to restore load capacity and halt further corrosion.
+
Protection of flanges and fastenings
Apply peelable, resealable encapsulation with corrosion inhibitor to guard bolts, nuts, and flanges.
+
Shim and level general equipment
Eliminate soft-foot and level machinery bases with high-compressive-strength cast shims and chocks.
+
Design guidance for the precise alignment of equipment
Technical support on chocking layout, load calculation, and alignment tolerances for new installations.
+
SF6-FIX solution for the prevention of SF6 emission leaks
A dedicated system for sealing SF6 gas leaks on switchgear flanges and fittings, cutting emissions without outage.
