Containment bunds

Containment bunds require a continuous chemical-resistant lining matched to secondary containment duty, spill chemistry, bund wall and floor geometry and maintenance access. This engineering guide frames the application intent without replacing the current system specification or product technical data sheet.

Use and application

The application intent is waterproofing of containment bunds. Start by qualifying the substrate, exposure, service level and maintenance constraints. Krypton ProLine MFE 100, Krypton ProLine CH55 and Krypton ProLine PU 1000 TC are typical reference products for this application. Compare the current Products and Systems documentation, and use the associated application context at Liquid containment to keep the scope distinct.

Spill chemistry, bund walls and floors

Secondary containment must hold a design spill volume without leakage through floors, walls or construction joints. Chemical compatibility, dwell time, cleaning regime and temperature drive the lining selection. Wall–floor coves, expansion joints, pipe penetrations, sumps, tank plinths and access points need a continuous, documented detail before the membrane route is fixed.

Layers and references

Define the sequence from prepared substrate through primer or bond coat, functional membrane or body coat, reinforcement where specified, and protective or finish layer where required. Use the current technical data sheet for preparation, mixing, consumption, thickness, overcoat windows and cure; the Calculator supports quantities, while Systems and the product references establish the applicable route.

Common mistakes

Selecting a lining from a generic waterproofing label without checking spill chemistry, dwell time and cleaning agents.
Treating the bund floor as the whole detail and omitting wall faces, coves, pipe penetrations, sumps or plinth terminations.
Closing the build-up before checking moisture, adhesion, thickness, pinholes and cure against the project containment requirement.

Operating sequence

1. Record spill chemistry, design volume, bund dimensions, substrate condition and service scenario. 2. Map wall–floor coves, joints, penetrations, sumps, plinths and repair zones. 3. Select a compatible route in Systems and verify every layer against the current technical data sheet. 4. Calculate quantities with the Calculator. 5. Approve a representative area, document preparation and application controls, inspect continuity and release the bund only when the project requirements are met.
