10. Pipelines

Extending land into water often poses challenges in maintaining the alignment of piping systems, especially when drains run across soft soil. Leca LWA serves as an excellent lightweight pipe surround, reducing pressure on the underlying soils and minimizing the risk of uneven settlement. An additional advantage of using Leca LWA as a pipe surround is…

9. Sheet pile walls

Extending land into water often presents geotechnical challenges due to soft and muddy soil conditions. Leca LWA effectively addresses these issues by compensating and reducing the load on confining structures. Leca LWA is well-suited for use in quay and land extension designs, including sheet piles, sheet pile cells, and caisson structures. It is also ideal…

8. Floating islands

Floating Ecosystem Modules offer numerous benefits, such as habitat creation, urban waterscaping, water quality improvement, and wastewater treatment. The lightweight nature of Leca LWA not only enables the islands to float but also simplifies the assembly and installation of these structures. The unique shape and porous structure of Leca LWA promote plant root growth and…

7. Walk/bike road

The construction of embankments on weak and compressible soil deposits often results in soil consolidation and settlement due to the embankment’s weight. Factors such as the embankment’s height, the depth of the weak soil layer, and the soil strata’s consolidation properties can lead to significant settlements. These can create challenges for maintaining road evenness, functionality,…

6. Retaining walls

When a fill structure is placed and compacted on a landscape, it generates additional loads, which are particularly significant in areas with soft soil subgrades. The load magnitude depends on the fill material’s density and thickness. These additional loads often lead to long-term settlement of the embankment or structure. The extent of settlement is proportional…

5. Railway

Constructing embankments on weak and compressible soil deposits often leads to soil consolidation and settlement due to the embankment’s load. Depending on the embankment’s height, the depth of the weak soil, and the soil strata’s consolidation properties, these settlements can be significant, posing challenges to road evenness, functionality, and long-term durability. The lightweight properties of…

4. Tunnels

In regions susceptible to mining subsidence or where ground conditions feature natural voids, culverts, or tunnels with a risk of collapse, reducing the overlying weight with Leca LWA provides an effective solution. This is especially crucial during tunnel construction, where unexpected voids or small cavities around the concrete may collapse onto the structure. Lightweight filling…

3. Bridge abutment

Constructing embankments on weak and compressible soil is a common challenge, as the embankment’s weight often causes soil consolidation and settlement. Thanks to the lightweight nature of Leca LWA, settlements in the transition zone between structures and roads or railways are significantly reduced or even eliminated. Moreover, the aggregate’s excellent drainage capacity ensures long-term load…

2. Bridges

Leca LWA is an ideal choice as a lightweight aggregate for concrete products. Its low weight enables the production of lightweight masonry blocks with excellent insulation properties. Ready-mix and precast lightweight aggregate concrete (LWAC) can be manufactured in various densities, achieving compressive strengths of up to 70 MPa or more. Today, LWAC is widely applied…
