Classic Collection
Our original engineered stone sump cover collection. Superior strength, timeless simplicity, and our widest range of standard sizes and load classes available.
Capable of handling everything from pedestrian footfall to heavy-duty vehicle traffic, our Classic catch basin covers are all about style and substance. Choose from our existing collection of best-selling colours and textures, add optional matching trimmer frames—or, go bespoke with a fully custom sump cover design.
Composition
<1% crystalline silica
Our composite blend substitutes materials such as quartz with safer alternatives. All of our engineered stone sump covers now contain less than 1% silica and have been approved for use in Australia.
95% natural aggregates
Each sump cover is made with a minimum of 95% natural aggregates and only 5% hybrid polymers. This creates a product that’s more sustainable, with a more natural appearance and a durable finish.
30% recycled materials
All our sump covers contain a minimum of 30% recycled materials. Any excess stone and steel that doesn’t meet our high manufacturing standards is repurposed as raw material for future projects.
Reinforced with steel frames
By reinforcing our sump covers with treated steel frames, we achieve the same strength as cast iron alternatives. Plus, by reducing steel usage by 80% in our production process, we’ve cut our carbon footprint by 16 times.
Specifications
Engineered stone sump covers. Sustainable, versatile and built to last a lifetime.
Approved worldwide
All the materials in our grating products meet the latest global safety standards. This includes the new legislation that applies to products containing crystalline silica.
Rust + corrosion proof
The rust-resistant, anti-fade properties that come with engineered stonework mean our decorative sump hole covers are designed to last a lifetime.
Low heat absorbency
Jonite sump hole covers absorb less heat than traditional metal and cast iron grates, helping to combat the effects of urban warming in cities with hotter climates.
Cost-effective + scalable
Our maintenance hole covers come in a range of standard sizes—and can be interlocked together to cover larger surface areas using metal sub-frames and our purpose-built splines.
Heavy duty support
Incorporate our optional trimmer frames into your larger storm drain grate designs to provide additional support without compromising on aesthetics.
