    What is basalt wool

    Basalt or stone wool is a type of mineral wool and is a pressed tile of interlaced fibers, the basis for which are igneous rocks, mainly basalt.

    Due to its thermal insulation properties, the insulation prevents heat loss even in the cold season and keeps you cool in hot weather. It was first used as an insulating material by the Hawaiians, who found basalt threads after volcanic eruptions and adapted them to insulate their homes.

    Today it is widely used in both the private and industrial sectors. It is suitable for insulating walls, floors, partitions, roofs, equipment, pipelines.

    What basalt wool is made of

    The modern process of its production is similar to the work of volcanoes, thanks to which this material was discovered . It is melted by heating to a temperature of 1500 ° C, then fed into a centrifuge and long fibers are obtained from it. Then they are pressed together into a plate, using binders for fastening – various compositions of formaldehyde. After manufacturing, the products are cut into slabs, mats, cylinders and segments for different surfaces: straight and curved.

    What is bituminous mastic

    Outwardly, it is a pasty black mixture. It is very viscous and plastic, so it is easy to apply. After hardening, it turns into a seamless monolithic base with high waterproofing properties, which make it possible to almost completely eliminate the possibility of leaks.


    Produced by melting bitumen and various additional components. In addition to the bituminous base, it contains the following elements.

    • Inclusions: ash, asbestos, brick powder, quartz, limestone, mineral wool. They provide density.
    • Thickeners: chalk or peat chips, which determine the viscosity of the consistency and ease of its application.
    • Fibrous fillers that make the composition resistant to bending and perform the function of reinforcement.

    What is bituminous mastic used for

    This is one of the most common waterproofing materials used in construction and repair for the following types of work.

    • The device of a new roofing or repair.
    • Waterproofing pools, wells and fountains.
    • Installation of tiles in rooms with high humidity.

    Construction Honored with AGC Builders

    Last night, Construction was honored to accept a Best Builders Award from the Associated General Contractors of Vermont for the construction of the $31.3 million Vermont Public Health Laboratory. There is so much to celebrate about this project – from both a construction and community perspective – and it was so gratifying to have that impact formally recognized in the contracting community.
