1. The use of low-strength (sand-clay, lime-clay, etc.) grouts for filling the gap between piles and the walls of leader holes having a diameter of no less than the diagonal of the cross section of the pile and a depth equal to the stratum prone to slump-type settlements is one of the most effective measures for reducing additional loads on precast piles due to loading-friction forces in soils classed as type-II in terms of proneness to slumptype settlement. 2. Use of jackets formed from polyethylene film on cast-in-place piles ensures significant reduction in additional load due to loading-friction forces. In this case, however, it is necessary to adopt measures to ensure the film's longevity over the entire period during which the building or structure is occupied. 3. Considering the extremely high efficiency of anti-friction coatings on piles in soils classed as type-II in terms of proneness to slump-type settlement, it is necessary to continue and expand research in this direction.
