Concrete Headwalls: JKH’s precast concrete headwalls are essential for effective drainage systems, preventing erosion at discharge points into watercourses like rivers, ditches, swales, and attenuation ponds. They offer a range of standard and custom headwalls to meet unique project requirements and budgets.
Customised Headwall Colours: For areas where aesthetics are important, JKH offers coloured headwalls that blend seamlessly into the surrounding landscape. With 24 colours available, they can also powdercoat steelwork to match.
Concrete Inspection Chambers: Inspection chambers are typically installed at changes of direction in main drains, providing rodding points in long runs of drain. They are also used for connecting lateral drains at various depths and as tumbling bays to slow drainage water on steep slopes.
Gratings & Steelwork: Steel gratings are crucial for maintaining effective drainage systems, preventing debris and pollutants from entering and ensuring waterways remain clear and functional.
Memorial Bases: Proper foundations for headstones are essential for stability and longevity. Poor-quality foundations can lead to sinking or tilting, compromising integrity. JKH supplies high-quality, steel-reinforced concrete memorial bases, offering solutions from small bases to specialized war grave saddles.

Why Low-Carbon Precast Concrete Is No Longer a Compromise
As the construction industry accelerates toward net-zero targets, the demand for sustainable materials has never been higher. While low-carbon concrete has been widely adopted for in-situ applications, precast concrete has traditionally lagged behind—mainly due to concerns around strength, durability, and consistency.
But that’s changing.
Thanks to innovations like ECO 1® from JKH, it’s now possible to achieve CEM I-equivalent performance in precast applications while significantly reducing carbon emissions. This marks a pivotal moment for the industry: low-carbon no longer means low-performance.
In this review, we’ll explore how low-carbon precast concrete has evolved and why it’s now a viable—and often preferable—alternative to traditional mixes.
What Is Low-Carbon Precast Concrete?
Traditional precast concrete is manufactured off-site using a high-cement mix, offering excellent strength, consistency, and durability. However, cement production is a major contributor to global CO₂ emissions.
Low-carbon precast concrete replaces a significant portion of cement with supplementary cementitious materials (SCMs) like GGBS or fly ash. These mixes have historically been seen as less suitable for precast due to slower curing times or reduced early strength. But with proprietary blends like ECO 1, that’s no longer the case.
Key Differences—and Why They Matter Now
Performance Without Compromise
Traditional Precast: Known for high strength and durability, especially in demanding environments.
ECO 1 Low-Carbon Precast ECO 1: Matches or exceeds traditional performance. ECO 1 retains CEM I standards while reducing cement content by 46%, achieving over 75 N/mm² at 28 days. It’s fully compliant with BS 8500-2:2023, including Design Chemical Class 4 and Design Sulphate Class 4—making it suitable for even the most aggressive environments.
Environmental Impact
Traditional Precast: High embodied carbon due to cement content.
ECO1 Low-Carbon Precast: ECO 1 reduces CO₂ emissions by up to 49% with its ECO 1 ULTRA® variant, offering a genuine path to sustainable construction without sacrificing quality.
Consistency and Quality
Traditional Precast: Offers factory-controlled consistency.
Low-Carbon Precast: Now delivers the same consistency and reliability, thanks to advanced mix design and rigorous testing. ECO 1 is used as standard across all JKH products, proving its reliability at scale
Cost and Availability
Traditional Precast: Well-established and widely available.
Low-Carbon Precast: Once considered niche, it’s now mainstream. At JKH, ECO 1 is the default mix—offered at no extra cost—making sustainable choices more accessible than ever
Project Suitability
Traditional Precast: Ideal for high-load, high-durability applications.
Low-Carbon Precast: Now equally suited for these applications, while also helping meet sustainability targets, LEED certification, and government carbon mandates.
Conclusion: A New Era for Precast Concrete
The assumption that low-carbon concrete can’t meet the demands of precast applications is now outdated. With solutions like ECO 1, the industry can move forward confidently—combining sustainability with strength, and innovation with reliability.
At JKH Ltd, we’re proud to lead this transformation. Whether you’re building infrastructure, commercial developments, or sustainable housing, our ECO 1 range ensures you no longer have to choose between performance and planet.
Let’s build better—together.

JKH Ltd - The Role of Gratings and Steelwork in Drainage Systems
The Role of Gratings and Steelwork in Drainage Systems
When planning and executing construction projects, particularly those involving drainage systems, selecting the right materials is crucial. Drainage gratings and steelwork play an essential role in these systems, providing durability, safety, and functionality. In this blog post, we will highlight the specific products offered by JKH Ltd, including Vermin Gates, Standard Handrails, and Special Gratings & Steelwork. By the end of this article, you’ll understand why choosing the right grating and steelwork products can significantly impact the success of your project.
What are Drainage Gratings and Steelwork?
Gratings and steelwork are integral to the design and functionality of drainage systems, offering a combination of strength, durability, and efficiency. Gratings, typically crafted from robust steel, serve as covers for drainage channels, allowing water to flow through while preventing debris and larger objects from clogging the system. This open grid structure ensures efficient drainage, reduces the risk of flooding, and enhances safety by providing slip-resistant surfaces for pedestrian and vehicular traffic. Steelwork, encompassing beams, frames, and custom fabrications, provides the necessary structural support for these grates and the overall drainage infrastructure. Steel’s resilience against corrosion and environmental stressors ensures long-lasting performance, making it an ideal material for both the grating and structural components of drainage systems. Together, gratings and steelwork form a cohesive system that supports efficient water management, structural integrity, and safety in a variety of applications, from urban environments to industrial sites.
