About ISFA Bouw Materialen

A building materials supplier focused on waterproofing and tiling

ISFA Bouw Materialen supplies professional waterproofing, adhesive and mortar products from Nilego® and Krast Plus. We work with contractors, roofers, tilers and building owners who need materials that perform on site and clear guidance on how to apply them.

Our range is deliberately compact. Rather than a catalogue of thousands of items, we carry the products needed to prepare, waterproof and finish a surface, and we know how each one is applied. If you are unsure which product fits your situation, send us the details and we will tell you what will work.
