The advanced development of materials and technologies is not limited to the high-tech industry, and the construction industry and the sealing field also benefit from advanced working methods that provide a variety of solutions, with an emphasis on sealing options with excellent materials, extremely high durability, and optimal suitability for all types of constructions.
Those who still remember the old sealing methods may also remember the smell of the hot, black tar that was used to seal roofs in the past, as well as the layers of white lime that they used to paint the roof after tarring, to keep out the scorching rays of the sun.
The sealing materials that came after awareness of the ecological and environmental damage caused by the use of hot tar also included limitations and disadvantages, including: limited effectiveness against standing water and harsh weather conditions, air pockets that formed between the material and the surface and caused the accumulation of standing water, weak points in the application of the sealing under solar water heaters and collectors placed on the roof, sealing defects in areas where there are slopes, and more.

The recognition of the importance of roof sealing for the protection and durability of the structure, as well as for sanitation and adequate living conditions for those living in the structure, has led to investment in the development of advanced sealing methods and solutions to challenges, which are especially important to recognize.
Battel casting is not a waterproofing material, but rather a waterproofing solution that provides a quality base for advanced waterproofing materials, and supports the waterproofing system by creating slopes for the natural removal and drainage of water from the roof.
Many roofs suffer from sealing failures and defects due to wear and tear of the sealing layer, structural damage resulting from the installation of various systems on the roof, the fall of a heavy object and other hazards, as well as flat roofs built under old standards and not including drainage and disposal solutions for standing water.
Upgrading the structure and sealing using Betkel casting is carried out by combining a cementitious mixture of materials including cement, sand, and foaming agents, with an advanced application technique using compression and pressure, which creates uniform application, leveling, and sealing, and allows for the planning and application of required slopes with an extremely high level of precision.
Batik casting does not replace the need to apply an additional waterproofing layer, but serves as an excellent, lightweight base suitable for the application and adhesion of various types of high-quality waterproofing membranes.
Along with the benefits of betel nut molding in the field of sealing, it is also a material that provides thermal insulation and acoustic insulation at an extremely high level.
Quality waterproofing is based on a combination of a variety of solutions and layers, which are designed to support each other and prevent water from penetrating the construction at different stages. In addition to applying a quality waterproofing layer to the roof, developments in materials and elements help to trap water penetration in the event of sealing defects, through the insertion of water stops. Water stops are elements inserted into the roof infrastructure, made of unique chemical materials, which cause them to swell in the event of water penetration, with the volume being created as a result of trapping water and preventing its penetration into the structure.
Waterstops can also be applied to external weak points, at connections between the roof of the building and the walls and drainage systems, thus increasing the effectiveness of the sealing and preventing sealing defects.
Crystalline sealant is a sealant designed for concrete surfaces, and is designed to address the unique characteristics of concrete, which is a leading material in the construction industry in Israel.
Concrete is a strong and rigid material on the one hand, but is prone to cracks and crevices that tend to accumulate moisture and dampness, which weakens the foundation on the other hand.
Crystal sealing is an innovative and advanced development, applied with various sealing techniques that create penetration of the material deep into the concrete alongside an external sealing layer, and through a unique chemical process releases hard and durable crystal crystals that strengthen the concrete infrastructure, prevent the penetration of water molecules and protect against dampness, humidity and mold formation, but allow the passage of air molecules and improve the quality of the roof's insulation.
Even among the more familiar sealing materials, one can find innovations and technological improvements, such as combining polymeric sealing materials with other materials to increase efficiency, producing thicker and stronger bituminous sheets and combining them with UV protection layers, developing more efficient welding methods and injection sealing devices for full accessibility to any location and addressing accessibility challenges in sealing.
