The long service life of expanded clay is achieved thanks to several factors, including:

• chemical inertness
• high strength
• non-combustibility
• ability to withstand significant temperature fluctuations
• moisture resistance
• unattractiveness to rodents

Due to its high tensile and compressive strength, expanded clay can withstand heavy loads. This allows its use in the production of expanded clay concrete, concrete screeds, and durable structural components.
Expanded clay does not react with acids, alkalis, alcohols, or mineral and organic substances. This contributes to maintaining its integrity even in aggressive operating conditions.
Expanded clay is frost-resistant, and its properties remain stable even under high temperatures. Because of this, expanded clay particles do not change or disintegrate across a wide range of temperatures.
Loose expanded clay is suitable for use in basements and attics where there is a risk of rodent presence. Expanded clay does not attract rats, mice, insects, or birds as a source of food or material for building nests or burrows.
Moisture resistance is another factor contributing to the durability of expanded clay. Different types have a water absorption rate ranging from 8% to 20%. Fired granules with a dense crust and closed pores hardly absorb moisture at all. They can be safely used in high-humidity conditions without the risk of premature degradation.
Expanded clay is non-combustible. Its fire resistance exceeds 1000 degrees Celsius. Therefore, short-term exposure to fire does not damage the material. Mold, fungi, and other destructive biological organisms do not form on expanded clay granules.
Not only expanded clay itself is durable, but also the materials based on it. To achieve long-lasting performance, it is essential to follow the recommended usage conditions.

Expanded clay has gained wide popularity in the construction of buildings, roads, production of building materials, and agriculture due to its long service life. Its lifespan exceeds 50 years, depending on the composition and operating conditions.
