The brothers Manuel J. Pérez Entrena and Jacinto J. Pérez Entrena make cobbled and pebbled paving in a great many forms and styles, such as ordinary or coarse, variegated or artistic.

They use mostly traditional methods and materials, such as earth and slaked lime, though they… also employ more modern techniques. The tools used in such work include strings, levels, metal rules, a mechanical tamper and compactor, mattocks, tape measures, hammers, masonry trowels, chisels, a levelling rod, stiff brushes and a watering hose or can.

Their procedure starts with the drawing of a sketch. The design is then set out on site, marked traditionally by hand on a bed of mortar. The pebbles forming the main design are laid and then filled in with the background pebbling. In the last stage the mortar is allowed to set and the paving is tamped and watered, so that finally the outcome can be admired.

In work such as the restoration of historic pebbling, as in the Alhambra and the Generalife Palace in Granada, a meticulous preliminary study is required along with detailed referral to photographic records of the former paving prior to removal. In repair work they seek to use as much as possible of the original materials.
