Tests have proved that H-piles can dependably carry heavier loads than usually are assigned to them. Concrete and timber piles are being loaded heavier. Prestressed concrete piles benefit from improved splicers. Gaining in use are H-pile extensions for precast. The H end, with cast steel protection, can assure penetration into compact material; it can prevent sliding of sharply battered piles or piles driven on steeply sloping rock; it provides protection to the vulnerable end of a precast pile. An import from Europe is an interlocking deep-web H that can be used with sheet piles for cofferdams or a strong wall. Improved mandrels have increased use of corrugated shell piles. The wave equation is increasingly used for determination of driving stresses and selection of the optimum combination of pile and hammer. Dynamic measurement gives instant pile capacity information at minimum cost. More adequate soils investigation and foundation planning can reduce overall cost. /Author/
