For the Family Compensation Fund COMFENALCO, located in Cartagena, we performed the maintenance of the surface of the athletic track. This consisted of partial and total interventions, maintaining the current material installed. Thus, the activities performed for this project were: milling of the exposed layer (either black SBR base or red EPDM) for subsequent installation of new layers, supply of new material to complement or install the finishing surface in the sectors where it has currently lost its thickness, layer or color, and white demarcation (lines and numbers).
