Looking for signs of leaks, especially at accessible surfaces and junctions.

Deciding which layers need to come off before the new waterproofing goes down.

Installing a system suited to the substrate, the space and its final covering.

Coordinating the work with roof layers, details and the selected system.

Paying particular attention to walls, thresholds, drains and pipe penetrations, in line with the selected system.

Adding the protective and final layers included in the quote.




If water is getting into a Pazin property, tell us where the marks appear and when. Photos of both the interior and the terrace, balcony or roof above help us inspect the layers, slopes, thresholds and drains.
More about this service ↗
Start with the property location, the work you have in mind and approximate measurements. We'll take it from there.

Send photos of the existing space and the parts you want to change. A floor plan helps if you have one.

We inspect the property, including existing surfaces, access and the details that may affect the job.

Your quote sets out the work, materials and the basis for the quantities.

Before starting, we settle the work, timing, materials and how we'll stay in touch.

We work through the agreed stages and discuss any changes before carrying them out.

At the end, we check the completed work and finishing details together.
Note when damp appears, how long it lasts and whether it relates to rainfall or use. Photograph the wider area and junctions, not only the wet spot.
Photos help us start the conversation but cannot always show every layer. We arrange an inspection to determine the scope and solution.
That depends on the condition of the existing layers and selected solution. We decide after inspection.
The final covering can form part of a broader scope. Our quote clearly lists the preparation, waterproofing and finishing included.
Tell us a little about the property and what you want to do. We'll talk through the work and arrange a visit if needed.
