Earth-moving hammers (also known as ground-displacement hammers) are pneumatic tools used for the trenchless laying of utility pipes beneath paths, roads, green spaces and buildings. They displace the soil laterally to create a void into which pipes or cables are then pulled.

Variants differ in diameter (45–180 mm), length (1.2 to 2 m), impact rate and reverse function. Larger models can drive over 30 metres per operation. Models with a retraction function allow for the removal of obstacles without excavation.

Common manufacturers include TT-Group / Tracto-Technik, Grundomat, Krennter, Earth Tool Company, HammerHead, STA-Maschinenbau and Schmidt Kranz.

Earth rockets are used for laying water, gas, electricity and telecoms cables beneath paved surfaces, for installing service connections without breaking ground, in gardening and landscaping, and for laying irrigation systems in sports facilities.
