The union of Afesa Medio Ambiente and Excavaciones Mendiola creates a leader in environmental services for heavy industry, energy and construction, with integrated capabilities across waste management, soil remediation, demolition and excavation.

Established in 2026 through the acquisition of Afesa Medio Ambiente and Excavaciones Mendiola, the group operates four complementary business lines —contaminated soil remediation, industrial demolition, waste management (industrial and construction waste) and excavation— enabling it to offer clients a fully integrated service solution across transformation, rehabilitation and decommissioning processes. Headquartered in the Basque Country and operating across the Iberian Peninsula and the Islands, with a client base spanning the industrial, energy and construction sectors, the group combines Afesa’s technical expertise and market positioning with Mendiola’s specialisation in civil works and construction waste management.

Against a backdrop of tightening environmental regulation and accelerating decarbonisation and industrial transformation, the group is positioned as the partner of choice for major industrial players and developers requiring technically complex solutions with full environmental guarantees.
