External Waterproofing CHAD Group – Cladding, Render, Texture & Mouldings

CHAD Waterproofing

One thing to consider during planning and construction of bathrooms, showers, laundries, kitchens, and other spaces that are likely to be exposed to humidity is the waterproofing capability of the wall frames in these so-called “wet areas”. Whether the outside surface is tiled or painted, it is essential that the wall frames have a reliable waterproofing capability to avoid any water leakage and to protect the concrete underneath the surface as mandated by the National Construction Code (NCC).

An element essential to improving any wall frame’s waterproofing ability is a material called plasterboard. Plasterboards are panels typically pressed between a facer and a backer. It is important to have a wet area plasterboard installed in your wall frames because it plays a vital part in making sure that everything behind the external surface of the wall remains dry, intact, and free from moisture that could cause mould, leakage and other problems.



A flexible and blue water based membrane – Aquashield FS is fast drying, UV stable, and does not require the use of additional reinforcement.

Aquashield FS is ideal for waterproofing of shower recesses, bathrooms, laundries & light foot traffic areas. Internal or external waterproofing applications over concrete, render, rendered brickwork, fibre-cement, gyprock, and particle board surfaces.

Cement based tile adhesives can be applied over Aquashield FS. Aquashield FS complies with AS3740:2004 as a Class III Elastomeric Wateproofing Membrane.

Apart from their own products, CHAD want their consumers to have a broad range of choices so they also supply products from Gyprock, Boral, Knauf and James Hardie – other highly trusted plasterboard creators.

Gyprock Aquachek’s core, face, and back are resistant to moisture and humidity without compromising its structural integrity. It has exceptionally low water absorption capabilities and dodges moisture movement, therefore, provides a stable canvas for ceramic tiles. Just like CHAD Plaster’s wet area boards, Gyprock Aquachek is manufactured in compliance to the Australian Standard AS2588.

Boral’s wet area boards are called WETSTOP. They have a water-resistant core and are also a good choice because the boards possess the following qualities: lightweight, have water resistant linings, are suitable for wet area internal wall and ceiling applications, are economical and are suitable for tiling.

Knauf offers standard wallboard intended for general use along with high-performance boards possessing characteristics like moisture resistance, impact resistance, sound reduction and reverberation, fire protection, control of water vapour, and thermal insulation.

James Hardie Villaboard is also designed for bathrooms. A seamless flat, internal wall or ceiling lining that can be painted, wallpapered or partly/fully tiled to create a wide range of design looks. James Hardie is suitable for wet and high traffic areas.
