Fast Delivery of LECA® LWA


LEca is used extensively within structural engineering and geotech

If your building material weighs less, it makes life for construction workers onsite easier. Lifting a LECA® Block weighing a few kilograms is manageable, but lifting a block made from alternative material which could weigh up to four times more is certainly more difficult. Not only is LECA® LWA lightweight but you can pneumatically blow them into place with our blowing vehicles when access is narrow and difficult; Fast, Easy and Flexible.

Geotechnical Solution


Climate change has been a major topic of discussion in recent years, and although the construction industry seems to be a slow starter, Mats Pettersson, CEO of Murbiten in Gothenburg, sees the trend going in the right direction


Leca® LWA can be used in a variety of structural and geotechnical type projects and its significant properties such as being light in weight, extremely strong and ease to handle have proven that Leca® LWA is for many civil engineers the aggregate of choice. 

When used as a filling, LECA® LWA being a lightweight insulation material, considerably improved the overall thermal balance of the reservoir and prevented freezing of the structure. Leca is a material with high frost-resistance and ensures durability for many, many years, says Maciej Kotecki.

Renovation of Old Brick Vaults of Stara Orunia

Big problems occurred during the renovation of Stara Orunia, such as insufficient load-bearing capacity of old brick structures and low thermal insulation. Both were successfully solved by LECA® LWA

Green Stories from Leca®

Borrowed From Nature Sustainability

Leca® Lightweight Expanded Clay Aggregate is a unique and natural product, which life cycle is not linear, but circular. Leca® Lightweight Expanded Clay Aggregate can be ‘reborn’ when the material has been in use for up to 100 years.
