Projects

ARDEX Waterproofing membranes were used in NAiAD RHIBs with inflatable collars, delivering reliable performance in demanding marine conditions.

ARDEX Waterproofing Membranes in Marine Applications

ARDEX Butynol® was chosen for the inflatable bladder for its proven water resistance and durability, the same qualities that make ARDEX membranes ideal for tanking and wet-area protection.

ARDEX Waterproofing Membranes in Marine Applications

Project Overview

ARDEX Waterproofing membranes are widely recognised for protecting buildings from water ingress. This project case study demonstrates their adaptability in marine environments, specifically in a range of NAiAD Rigid-Hulled Inflatable Boats (RHIBs) that have an air filled, inflatable bladder within the collar system. These vessels are deployed for marine rescues, enforcement and recreational use, where reliability under extreme conditions is non-negotiable.

Challenge

Marine environments present unique challenges:

Exposure to saltwater and weathering
High mechanical stress from waves and impact
Need for airtight integrity to maintain buoyancy and safety

Materials can sustain damage and degrade quickly under these conditions, leading to costly repairs and operational risks.

Solution

ARDEX Butynol® was selected for the inflatable bladder due to its proven water resistance and durability. The same properties that made ARDEX membranes ideal for below-grade tanking and wet-area protection translate seamlessly to marine environments:

Superior waterproofing performance
Resistance to vibrations and environmental extremes
Repairability
Portability
Long-term reliability without compromising flexibility

These precision-engineered bladders are prefabricated in ARDEX Christchurch manufacturing facility and transported to NAiAD for valve install and dispatch to all corners of the world.

Key Component Product

ARDEX Butynol® – a synthetic rubber membrane known for exceptional waterproofing, flexibility, and resistance to harsh environmental conditions.

Outcome

The result is a RHIB capable of enduring harsh conditions while maintaining structural integrity and buoyancy. ARDEX Butynol® extends the service life of these vessels, reducing maintenance costs and enhancing safety for critical missions.

This application underscores ARDEX’s versatility, moving beyond traditional building construction into specialised marine engineering.
