Deep Drilling in Israel: Leading Methods, Their Advantages, and When to Choose Each One
Almog Shaul Engineering Ltd. operates in this field as a leading professional entity, combining hands-on experience with careful engineering design. Choosing the right drilling method affects structural stability, execution costs, and schedules, so precise matching is required between the type of soil, design loads, and the technology available on site.
Common foundation drilling methods in Israel The term foundation drilling methods includes a variety of techniques, dry drilling, wet drilling with drilling fluid, steel casing drilling, continuous auger drilling, and others. Dry drilling is usually suitable for stable soils that do not collapse, when the groundwater level is low and there is no need for peripheral support of the walls. Wet drilling, by contrast, uses dedicated drilling fluids to stabilize the walls and allows deep drilling even in soft or water-saturated soils. The choice between the methods is made after soil tests and according to the static design requirements.
Dry drilling for medium and deep depths Dry drilling is especially suitable for stable clay or rock soils, where the risk of wall collapse is low. In this method, the required diameter is drilled, the bore is cleaned, a reinforcement cage is inserted, and then concrete is poured. When site access is limited, compact equipment is sometimes used together with crane trucks for lowering heavy cages and transporting equipment. Almog Shaul Engineering Ltd. applies dry drilling mainly in places where high efficiency, significant depth, and dense soil are required, and where no special wall support is needed.
Deep drilling in Israel with bentonite and wall support In areas with a high groundwater table, sandy soil, or loose fill, dry drilling may be dangerous and even impossible. In such cases, wet drilling with bentonite is used, a material that creates a thick slurry that stabilizes the bore walls and prevents soil and water intrusion. After the drilling is completed, part of the fluid is pumped out, a reinforcement cage is inserted, and concrete is poured using the tremie pipe method. This makes it possible to carry out deep drilling in Israel even at great depths and under high loads, while maintaining bore stability and site safety.
Steel casing drilling and special methods When the soil is particularly problematic, or when high geometric control of the pile diameter is required, temporary steel casing, a caisson, is used. This method is especially suitable in dense areas, near existing structures, or in complex geotechnical conditions. Almog Shaul Engineering Ltd. combines steel casing with additional methods, such as continuous auger drilling or staged drilling, to reduce soil movement, prevent damage to existing infrastructure, and ensure high quality concrete and reinforcement throughout the pile.
Choosing the right method for each project Choosing the correct deep drilling method in Israel is based on a detailed soil survey, load requirements, access limitations, and safety challenges. Combining geotechnical analysis, structural design, and practical site execution capability enables the best match between dry drilling, wet drilling with bentonite, or steel casing. Turning to an experienced professional such as Almog Shaul Engineering Ltd. makes it possible to review all alternatives, assess risks, and plan a reliable foundation system that will serve the structure for years.
