Leading supplier and manufacturer of construction and building materials, Aggregate Industries, has strengthened its Lytag offer with the relaunch of Sportag, a sustainable, lightweight drainage material.
Made from Lytag’s ground-breaking secondary aggregate, Sportag is an ideal solution for land drainage applications due to its rounded shape and material properties.
With a hydraulic conductivity 10 times that of natural aggregates, the product is particularly suited to golf courses, including slit trenches, gravel banding and Shelton Systems, as well as sports pitches.
Sportag’s secondary aggregate composition also allows for a 30% moisture retention rate, ensuring a healthier and more consistent facility. Reduces drought stress in hot or dry weather.
Alongside this, the product’s 40% void ratio helps aid longevity, improving aeration and allowing roots to penetrate further.
Steve Curley, General Manager from Aggregate Industries, said: “Having an effective drainage system in place will not only help future proof a pitch or green but also helps to ensure playability is possible regardless of season or weather conditions.
"Indeed, this has been a big factor in why Sportag has been so widely used on golf course greens and fairways. Re-launching this product gives us an ideal opportunity to reinforce the many benefits of using a secondary aggregate as a land drainage solution.
“Importantly, too, our Lytag lightweight solution is really leading the way when it comes to improving efficiency and reducing environmental impact in modern construction practice.”
A secondary aggregate and half the weight of standard aggregate, Sportag saves on natural resources, offering greater sustainability and reduced landfill. Its round and lightweight nature also means that it is easily handled, flowing easily into position.
In production for more than 50 years, Lytag lightweight aggregate is made from the fly ash generated by coal fired power stations. The revolutionary technology transforms the fly ash into small round pellets, which are then heated to 1,100°C. This creates a very hard pellet with a honeycombed internal structure of interconnecting voids within the aggregate, making it structurally robust yet lightweight.
The pellets formed are rounded in shape and range in size from 14 mm down to fines and can then be used as a superior, consistent, lightweight aggregate that is up to 40 per cent lighter than natural aggregate.
