We have a damp basement in our Eindhoven home from the 1970s. The concrete floor is cracking and staining. A contractor mentioned epoxy coating as a solution to seal it and make it look better. We're worried about cost and whether this will actually solve the moisture problem long-term. What should we expect to pay, and is epoxy the right choice?
Epoxy coating typically costs €40–80 per m2 in the Netherlands, so your 50m2 basement would run €2,000–4,000 labour and materials combined. However, epoxy alone won't fix damp—it's cosmetic. First, you need a moisture survey (€150–300) to find the source: rising damp, condensation, or external water ingress. Rising damp may need injection damp-proofing (€3,000–6,000) before coating. Condensation needs ventilation. This is governed by NEN 1010 (moisture standards in buildings). Skipping diagnosis risks the epoxy failing within years.
