  The Maya built their cities with Neolithic technology; they built their structures from both perishable materials and from stone. The exact type of stone used in masonry construction varied according to locally available resources, and this also affected the building style. Across a broad swathe of the Maya area, limestone was immediately available. The local limestone is relatively soft when freshly cut, but hardens with exposure. There was great variety in the quality of limestone, with good-quality stone available in the Usumacinta region; in the northern Yucatán, the limestone used in construction was of relatively poor quality. Volcanic tuff was used at Copán, and nearby Quiriguá employed sandstone. In Comalcalco, where suitable stone was not available locally, fired bricks were employed. Limestone was burned at high temperatures in order to manufacture cement, plaster, and stucco. Lime-based cement was used to seal stonework in place, and stone blocks were fashioned using rope-and-water abrasion, and with obsidian tools. The Maya did not employ a functional wheel, so all loads were transported on litters, barges, or rolled on logs. Heavy loads were lifted with rope, but probably without employing pulleys.
  
  Wood was used for beams, and for lintels, even in masonry structures. Throughout Maya history, common huts and some temples continued to be built from wooden poles and thatch. Adobe was also applied; this consisted of mud strengthened with straw and was applied as a coating over the woven-stick walls of huts, even after the development of masonry structures. In the southern Maya area, adobe was employed in monumental architecture when no suitable stone was locally available.
