Sunken Slab Filling Material
What is Sunken Slab?
Sunk slab are slabs that are cast a certain depth (200 or 300 mm or any other depending on design) below normal floor level. This extra depth is used for placing pipes and utility ducts. Sunken slab are used in the toilets, bathrooms, and washing places where we have our washing machines. The purpose of having a sunken slab is to conceal all the pipes below the floor. Since the pipes that carry water are concealed below the floor, care has to be taken to avoid leakage problems.
Why Expanded Clay Aggregate (ECA ®) is a preferred Green material?
The innovative lightweight Expanded Clay Aggregate (ECA ®) is the ultimate green construction material used for versatile applications for lightweight fill. It is also the most preferred sunken slab filling material in today's times. Expanded Clay Aggregate (ECA ®) is a 100% Inert aggregate that is light in weight and comes in sizes of 0-30mm (0-1, 0-2mm, 2-8mm, 8-15mm, 15-30mm).It has a bulk density of 240 to 880 kg/m3 and offers a Dry Thermal Conductivity of 0.09 to 0.10 W/mK which makes it an excellent material for versatile applications. Expanded Clay Aggregate is fire resistant, termite, and pest-free and has surface alkalinity of around Neutral Ph. ECA ® has a high resistance to chemical and weather conditions, hence is a safe aggregate. ECA ® does not produce any pollutants or toxic substances either during its manufacture or its use in the structure.
Expanded Clay Aggregate as a Lightweight Fill Material
In construction, horticultural, drainage, and geotechnical projects, expanded clay aggregate (ECA®) is primarily used as a Lightweight fill material to fill empty spaces and enhance the stability of structures. ECA is a high-quality, water-resistant, 100 percent inert, sustainable, highly compressive, and Lightweight material used in various applications.
Uses of Expanded Clay Aggregate as a Lightweight Filler Material
Expanded Clay Aggregate is the most preferred green filler material that is commonly used as Sunk Slab Fill Material.
Expanded Clay Aggregate can be used as a Lightweight filler material for sunken slabs. Sunken slabs also known as sunk slabs are often cast slightly deeper below the standard floor level to create room for pipes and utility casts. Sunken slabs are used in bathrooms, toilets, and other washing areas. The purpose of these sunk slabs is to conceal the piping system to avoid leakage issues.
Expanded clay aggregate is the most versatile sunken slab filling material that can be used both as sunken slab filling material and toilet sunken filling material to conceal underground pipes. Furthermore, sunken slabs should be filled with lightweight expanded clay aggregates sunken slab filling materials instead of the traditional alternatives such as Brickbat Coba or coal lumps.
Expanded Clay Aggregate is the only lightweight aggregate certified for geotechnical uses and is marked compliant with EN 15732 ( Lightweight fill and thermal insulation products for civil engineering applications (CEA) by CE.
Sunken slabs are preferred to be filled with lightweight Expanded Clay Aggregate (ECA ®) against traditional alternatives as
- CLC Broken Blocks / CLC Rubble
- Aircon blocks, AAC Blocks
- Brickbat Coba
- Light Weight Cinder
- Broken Red Clay Bricks
- Broken Fly Ash Bricks
- Coal lumps
- Burnt Tar lumps
- Brick Jelly and others
Hence, Lightweight Expanded Clay Aggregate (ECA ®) is a preferred green material for filling empty spaces in buildings mainly as a replacement to Brickbat Coba including Sunken Slab. ECA ® is also used for building toilet deck filling, roof garden filling, lobby filling, and other lightweight backfill applications.
