LYTAG ®
Lytag ® is made from pulverised fuel ash, a waste material produced from electricity production in coal-fired power stations. Manufactured in accordance with EN 13055, the standard for lightweight aggregates, Lytag is widely available within the UK and Europe. Lytag products are classified as secondary aggregates. This means that the quantity of fly ash being tipped is reduced and virgin aggregate extraction is reduced. By considering the use of Lytag products at an early stage in the design process, you have the potential to reduce the quantities of construction material required in a project. This leads to overall cost savings. Due to the reduced weight of Lytag products, larger volumes can be transported, reducing vehicle movements both on the public highway and site. Products: Geofill ® An 8/14mm lightweight aggregate used to raise levels or reduce pressure on retaining walls. Due to its shape and absorptive qualities, it will initially absorb up to 20% of the Geofill ® ’s weight in water, followed by letting water pass through without silting up Sportag ® A 4/8mm material used extensively in sports pitches and golf courses, acting as localised water run-off channels Hortag ® A 4/8mm material used within the horticulture market, available in small bags for use in garden drainage as well as improving root growth
