LECA® LIGHTWEIGHT AGGREGATE (LWA) PROVIDES FIRE PROTECTION IN BYHAVEN
We recently visited the construction site of the Byhaven project in Fredrikstad, where we got a closer look at the advanced and cost-effective building techniques being used. The project, which is part of the larger urban development project Værstetorvet, represents a new era in urban development and offers a mix of housing, office spaces, and retail areas, with a total of approximately 249 homes and a shopping center covering nearly 30,000 m².
Highly Efficient Delivery and Installation of Leca LWA
Joacim Hovde, concrete foreman at Solid Entreprenør, guides us through the process of blowing Leca LWA directly to the third floor via a 60-meter-long hose, a method proving to be highly efficient. With a delivery capacity of around 50 m³ per hour, Leca LWA is delivered straight from the truck, practically pre-compacted, with no need for manual unloading.
This technique reduces both labor and material waste on the construction site and completely eliminates the need for packaging.
FACTS
Project: Byhaven Fredrikstad
Contractor: Solid Entreprenør
Design: Bjølstad Utvikling AS
Leca product: Leca® LWA 8/20, pneumatic delivery
A Chosen Solution for Safety and Logistics
"Leca LWA was chosen for its many advantages, including fire safety and logistics, which require minimal setup space and resources"
Hovde states. He also highlights how quick and easy it is to install Leca LWA compared to alternatives like polystyrene, which would require extensive use of construction cranes and more manpower.
Setting New Standards for Urban Development with Sustainable Solutions
Since the start of the Byhaven project, around 3,500 cubic meters of Leca LWA have been delivered,used both as insulation material between floors and as fire protection between commercial and residential sections. Leca LWA has also been applied in the basement rooms and around the building’s foundation for drainage.
The project marks an important step forward in the urban development of Fredrikstad, just nearby the pedestrian bridge over to Stortorvet. With its approach to sustainable construction and innovative solutions,
Byhaven is setting new standards for future projects.
