BLOCKS
Leca® Blocks
-
LECA® is used for making solid blocks of lightweight concrete, hollow blocks and Lecaterm blocks.
-
LECA® solid blocks are suitable for inner-leaf walls, foundations, basement walls, partitions and outer walls. Specially-made LECA® floor blocks for solid-based floors are also available.
-
Special feature blocks like the hollow block and the grooved block are used for specific applications. The hollow block is especially useful as top of foundation under cavity walls.
-
The grooved block gives the possibility to make reinforced basement walls. Lecaterm blocks are made of LECA® lightweight concrete and foam plastic. Lecaterm is a complete building system consisting of straight blocks and corner blocks. Lecaterm blocks are used for outer walls an foundations.
-
Danish LECA® blocks provide effective protection against thermal bridge and are suitable for foundations, floors and walls. The blocks are easy to work with and provide excellent key for subsequent render or mortar application.
Leca® Application
Expanded clay stands out as a unique lightweight aggregate with versatile applications, serving as the ultimate all-in-one solution for sustainable use across various sectors. Its exceptional characteristics make it suitable for diverse applications in housing, infrastructure, and water management projects. The product is meticulously defined in numerous harmonized European standards, with all declarations compliant with approved European test standards, including adaptations for the Construction Products Regulation (CPR).
Expanded clay's versatility extends from enhancing plant growth in flower pots to manufacturing lightweight structural concrete for robust structures in challenging environments like the Northern Seas. In every application, expanded clay brings added properties that enhance the sustainability of the final construction, making it an indispensable component for eco-conscious projects worldwide.
Housing
The versatile application of Leca® LWA in construction spans walls, slabs, floor fillings, and drainage systems. Offering lightweight construction, thermal insulation, and soundproofing benefits, it enhances comfort for property owners and occupants alike in various projects, from residential villas to hospital renovations. Whether used as loose fill or in concrete mixes, its lightweight nature remains a key advantage.
Water Management
Leca® LWA plays a crucial role in infiltration, drainage, and water detention systems.
In Storm Water Management, Leca® LWA offers effective solutions by interacting with water to provide detention and drainage capabilities.
For applications like drinking water purification or wastewater treatment, expanded clay, such as our brand FILTRALITE®, exhibits excellent properties, ensuring outstanding results.
Infrastructure
Utilizing LECA® LWA in infrastructure projects, such as road, rail, tunnel, or water extensions, offers several advantages:
-
Low bulk density and high strength: LECA® LWA provides a lightweight yet robust solution.
-
Easy handling on-site: Simplifies construction processes and logistics.
-
Addresses geotechnical challenges effectively:
-
Load compensation: Distributes loads efficiently, reducing stress on the structure.
-
Reduced settlements: Minimizes ground subsidence over time.
-
Reduced earth pressure: Alleviates pressure on retaining structures.
-
Frost insulation: Provides insulation against frost, enhancing durability in cold climates.
-
These characteristics make LECA® LWA a highly competitive aggregate for infrastructure projects, offering efficient solutions to various geotechnical problems.
