Components

radical

土 tǔ

earth; soil

Left earth radical — a pictograph of a clod or mound of soil rising from the ground. The indexing element. Puts 墩 in the earthwork family with 块 (block), 堆 (pile), 堡 (fort), 坝 (dam), 坟 (mound, tomb). The radical states the substance: a 墩 is a solid block of earth, stone, or masonry — a pier, plinth, or pillar-base anchored in the ground.

phonetic

敦 dūn

kindhearted; weighty (here phonetic+semantic)

Right 敦 supplies the sound — dūn matches the parent reading with no drift. Helpfully, 敦 carries the flavour of 'weighty, solid, sincere' (享 + 攵, the earnest-urging graph). Same flavour transfers to 墩: a thick, weighty block of stone or earth, planted firmly. The phonetic doubles as semantic reinforcement for the squat, heavy meaning.
