Next-Level Beauty and Function of Sump Covers

The humble sump cover, or maintenance hole cover, first began life in the Roman Empire as slabs of stone or wood placed over point drainage systems that allowed maintenance workers access to covered drains carrying wastewater and sewage.

This omnipresent sewer cover is the basis of inspiration for Jonite’s designs, in which we aim to showcase the beauty of stone with modern technology and excellent craftsmanship.

Today, point drainage systems are found everywhere in the streets, commercial factory areas, residential areas, and more. Point drains require covers to prevent environmental contamination and prevent accidental falls. With Jonite point drain covers and sump grates, architects no longer face the problem of having to place these openings in inconspicuous areas, but instead can use these catch basin grates as an additional design element.

Incredible Benefits of Our Sump Hole Covers

With over 20 years of industry expertise and insights, Jonite provides reliable coverings for your sewer systems. An ideal combination of function and aesthetic appeal contributes to the success of our design. As the chosen supplier for many clients in the engineering, construction and architectural industry, we deliver product advantages including:

  • Low heat absorption: Lower urban temperatures by choosing Jonite sump covers with low heat absorption compared to traditional metal or cast iron grates. Traditional metal or cast iron grates absorb heat during the day, which can create the urban heat island effect through the raised temperature for surrounding buildings. Jonite sump covers were designed to combat the effects of urban warming, which is rapidly becoming a severe issue for cities in the changing climate, and include dielectric properties with an excellent electric insulator.
  • Rust and corrosion resistant: The unique material properties of Jonite products prevent rust and corrosion such that they are suited to last a lifetime for both indoor and outdoor applications. They also help deter theft, as Jonite hardscape products do not pose any value for scrap due to their stone material’s integrity.
  • Variety of standard sizes and designs: Jonite catch basin grates and sump grates come in a wide range of standard sizes that can be assembled with the addition of Jonite splines to form huge covers. This feature gives you the added edge of cost-effectiveness and sustainability. For multiple sump covers, a metal sub-frame may be used. Optional Jonite Trimmer Frames can be used to provide aesthetic flair and high-performance support for the heavy-duty channel and sump grates.

FAQ

What is the difference between a sump cover and a trench grate?

A sump cover is used for point drainage systems while a trench grate is used for linear drain systems. Usually, point drainage systems are less expensive as you use fewer grates.

Can I use sump covers as a complete replacement to trench grates?

It depends. You would need to consider several factors like the gradient and drainage requirements of a site. For example, linear drains may be more suited for a case that requires a massive dispersion of water from a wider area. Sump covers can also be used in conjunction with trench grates for better drainage.

Can I customize the size and design of my sump cover?

Yes. Just like with our trench grates, our transparent step-by-step process will help you with all your customizing needs. Feel free to reach out to one of us at Jonite if you need help.

Can I use Jonite sump covers for my driveway?

Yes, you can. Similar to Jonite trench grates, our sump covers can go up to D400 (500KN) Load Class. Check out our high-performance standard models for a wide range of sizes.

Are Jonite sump covers slip resistant?

Jonite sump covers are slip resistant. We have conducted Pendulum and Ramp tests on our products to make sure they meet industry standards for slip resistance. With a class V on the Pendulum test and an R10 on the Ramp test, Jonite can handle most locations and applications.

Are Jonite’s products sustainable?

Jonite commits to environmentally sustainable practices. We actively manage our energy, water, and waste with the future in mind. We use at least 30% recycled aggregates, which reduces carbon emissions by up to 80%.

Jonite products are also Singapore Green Building Product (SGBP) certified (4 ticks, leader). This means that you can score additional points under the Functional Systems Criteria (Flooring, Ceiling, Roof, External Wall, Internal Wall and Door systems) and/or Singular Sustainable Products outside of Functional Systems Criteria. This ensures that sustainability is integrated throughout the design and manufacturing process of green building products.
