Heavy-traffic car park waterproofing

Heavy-traffic car park waterproofing needs a floor and deck build-up that manages traffic loads, weather exposure, drainage and interfaces. This engineering guide separates the use case from the visible finish and points to the checks required before installation.

CE · EN 13813

OS 10 car park coating layers: Concrete floor slab, Humidity Primer, Rayston Floor D50 FR, Kryptanate 100 — System layers: OS 10 car park. Concrete floor slab → Humidity Primer → Rayston Floor D50 FR → Kryptanate 100.

Use and application

The application intent is heavy-traffic car park waterproofing. Start by qualifying the substrate, exposure, service level and maintenance constraints. Humidity Primer, Rayston Floor D50 FR and Kryptanate 100 are typical reference products for this application. Compare the current Products and Systems documentation, and use the associated application context at Kryptanate m parking to keep the scope distinct.

Traffic, waterproofing and service conditions

Performance follows real vehicle traffic, turning, braking, impact, cleaning chemicals and weather exposure on open or semi-open decks. Moisture and cohesion of the substrate, joints, falls, drains, thresholds and transitions should be resolved before the waterproofing and wearing 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

Choosing a light parking or pedestrian finish for heavy turning, braking or chemical loads it was not designed to carry.
Leaving joints, drains, thresholds and deck interfaces out of the detail set and inspection plan.
Closing the build-up before checking moisture, adhesion, thickness, cure and weather windows for the deck.

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.
