Primary and secondary liquid containment
Primary and secondary liquid containment require a continuous barrier matched to water exposure, substrate movement and maintenance. Match the build-up to substrate, exposure and detailing; confirm the current system specification and product technical data sheet.
Use and application
This page covers primary and secondary liquid containment. Start by qualifying the substrate, exposure, service level and maintenance constraints. Rayston Epoxy 100 and Polyurea Rayston are reference points for this use case, not an automatic system selection. Compare the current Products and Systems documentation, and use the associated application context at Containment bunds to keep the scope distinct.
01
Water exposure, substrate movement and detailing
Waterproofing or lining performance depends on the water chemistry, hydrostatic and immersion cycles, substrate condition and maintenance regime. Joints, corners, penetrations, thresholds and transitions need the same continuity as the main field.
02
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.
03
Common mistakes
- Treating the open field as the whole waterproofing detail and omitting joints, penetrations, corners or terminations.
- Applying over damp, contaminated or weak substrate without a documented preparation and moisture check.
- Selecting a product from the water label alone without checking chemistry, immersion, cleaning and repair requirements.
04
Operating sequence
1. Record the exposure, dimensions, substrate condition and service scenario. 2. Map joints, edges, penetrations, drains, upstands 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 the completed build-up, and release it only when the project requirements are met.
