Before we start: what we know about Aldarb

Is it worth waterproofing the floor and balcony of a duplex in Aldarb, and how do you know if it is needed? Aldarb's centre sits about 79 m above sea level, and the town is about 18.7 km from the sea coast. Those facts matter because a duplex here has its own upper floor and balcony exposed to the weather, and water finds its way through any weak point in the slab, the joints and the balcony edges. Waterproofing the floor and balcony is the way to stop that moisture from reaching the living space below. Our work on duplexes covers the floor slab, the balcony surface and the junctions where the two meet the wall, with treatments priced by area or length so you can see what each part of the job involves.
Our inspection starts with a walk through both levels of the duplex to look for damp patches, staining, hairline cracks and blistering on the balcony surface. We check the slope of the balcony floor and whether water pools after rain, because standing water shortens the life of any coating. Where cracks are found, we measure their length, since crack injection is charged per metre, and we note which areas are suitable for a liquid roof membrane, spray foam, epoxy coating or a bitumen membrane. The result is a written scope that lists each treatment with its area or length, so you know exactly what is being done before any work begins.
Before the visit, gather the details that help us assess the duplex accurately. Note any areas where you have seen leaks or damp, and when they appear, especially after rain. Tell us which floor and balcony surfaces you use most, and whether any tiles, paving or fittings are already in place. Clear the balcony of furniture and plants so the surface can be checked properly, and have access to both levels arranged for the inspection. If you have any earlier waterproofing records or repair invoices for the property, keep them ready, as they help us understand what has already been tried.
In a duplex, the two floors often share lines, so tests are done floor by floor.

Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
