About us

Last van Vocht.nl is part of Heemsteeds Vochtweringsbedrijf Okx (H.V.O.) and has been a specialist when it comes to leak detection since 1989.

We have the knowledge and experience needed in order to prevent and solve all moisture related problems in both private and corporate structures. We take care of both smaller projects such as minor damages caused by leakage, as well as larger projects such as complete basement renovations. The various services are carried out by owner associations, caretakers, real-estate developers, and contractors (who typically combine repairs to the foundations of a structure with the installation of a new concrete basement).

Aside from the various moisture related problems in basements, we also take care of rising damp by utilising a patented injection method which seals as well as strengthens walls and floors.

By having found the perfect balance between expert knowledge, experience, and specialised equipment we are always able to provide you with the best possible solution; whatever your problem might be, we take care of it in a professional and efficient manner.

H.V.O. is a flexible organisation which always takes great care in catering to our customers’ wishes.

Do not hesitate to get into contact with us! One of our colleagues will be more than happy to provide you with advice (non-committal).
