Acid-resistant basalt brick

Basalt brick, produced from melted basalt, is widely used for lining tanks, pickling baths, vats, scrubbers, as well as sewer and drainage systems. Its primary role is to provide reliable protection for walls and bottoms against aggressive environmental influences, making it an essential element in the range of acid-resistant construction materials.

In the modern market, basalt brick not only competes with but also replaces acid-resistant ceramic tiles and bricks, thanks to its high resistance to both organic and inorganic acids and alkalis, zero water absorption and porosity, exceptional strength, and wear resistance. The experience of major global manufacturers using basalt brick shows that under identical operating conditions, its service life is three times that of ceramic counterparts. This advantage allows significant reductions in regular and major repair costs, while extending the period between repairs, thus lowering production costs.

Acid-resistant basalt brick is applicable in any climatic conditions, whether outdoors or indoors, due to its resistance to temperature fluctuations. Its high strength and resistance to dynamic loads make it an ideal choice for use in the most demanding conditions, including for lining the most wear-prone bottom parts of tanks and collectors.

When lining pickling baths, smokestacks for acidic gases, tanks, and containers containing acids and alkalis, basalt brick must be laid exclusively on acid-resistant mortar. This ensures the protection of the joints from leaching and prevents the penetration of chemically active substances under the lining and their further spread into the environment.
