Leca Balls Primary Applications
This isn’t a “miracle” product, but it has an amazing range of uses.
Once you start to see the value of LECA clay balls, there are so many things they can be used for.
Hydroponics & Plant Cultivation
Transform your growing systems with LECA’s exceptional drainage properties. These expanded clay pebbles create the ideal free-draining substrate for hydroponics, providing excellent aeration for root development while maintaining proper moisture levels
Insulation Under Concrete Bases
Enhance thermal performance of concrete floors and foundations with LECA. The unique honeycomb structure of each clay pebble creates countless tiny air pockets that dramatically improve insulation properties while reducing the overall weight on foundations
Green Roof Construction
LECA is the perfect material for green roof installations, offering lightweight drainage and plant support. The clay pebbles significantly reduce the structural load while providing excellent water management capability for rooftop gardens and living roof systems
Chimney Flue Fill
Provide effective insulation around chimney flues with LECA’s fire-resistant properties. The lightweight clay aggregate creates a stable, insulating surround that improves flue draw, retains heat, and enhances safety with its non-combustible nature.
Drainage Solutions
The porous nature of LECA makes it perfect for drainage applications in landscaping and construction projects. Its ability to manage water effectively helps prevent waterlogging while maintaining structural integrity
Lightweight Concrete
LECA serves as an excellent aggregate for producing lightweight concrete with enhanced thermal properties. When used in concrete mixes, it significantly reduces structural weight without compromising strength—ideal for construction projects requiring reduced load on foundations
Leca Balls Sustainability Benefits
LECA clay balls offer impressive environmental credentials that align with modern sustainable building practices. During manufacturing, 1m³ of clay transforms into 5m³ of lightweight expanded clay aggregate—a highly resource-efficient 1:5 return.
The durable, long-lasting nature of LECA ensures sustainability throughout its lifecycle, making it an environmentally responsible choice for your construction or gardening projects.
