About Membriko
We are Portugal's specialists in EPDM membrane installation. We combine deep technical knowledge, certified materials and an unwavering commitment to quality to deliver waterproofing that lasts for decades.
Our Mission
At Membriko, we are dedicated to protecting buildings, infrastructure and investments with the most advanced waterproofing technology available — EPDM membrane. We believe every project deserves personalised attention, the highest quality materials and installation executed with technical rigour and professionalism. Our commitment is to lasting results — roofs, pools and structures that protect for decades, not years.
Our vision is to be the national reference for EPDM waterproofing solutions, recognised for technical excellence, the sustainability of our practices and the trust our clients place in us for decades.
Our Values
Quality Without Compromise
We exclusively use EPDM membranes from manufacturers certified to EN 13956, ASTM D4637 and CE marking standards. Every installation follows a rigorous quality control protocol — from substrate preparation through to final inspection of seams and details. No cost-cutting that compromises system integrity.
Proven Experience
Our team has accumulated years of experience in EPDM waterproofing across Portugal, with hundreds of completed projects in residential, commercial and industrial roofing, swimming pools, green roofs and civil engineering infrastructure. That track record translates into efficiency and predictability for our clients.
Professionalism and Transparency
From the first enquiry to final handover, we operate with transparency, punctuality and clear communication. Our quotes are detailed and free of hidden costs. Our teams arrive prepared, work in an organised manner and leave the site clean. The client tracks progress at every stage.
Environmental Responsibility
EPDM is the waterproofing membrane with the lowest environmental impact across its lifecycle — 100% recyclable, free of phthalate plasticisers and with a lower carbon footprint than PVC or bitumen. We choose materials and practices that minimise waste, avoid hot-work and contribute to more sustainable buildings.
