Floor & balcony waterproofing in Aldarb: with a verifiable technical report

Prepared by the technical team · editorial review · last updated 13 November 2026 · Sources

Before we start: what we know about Aldarb

Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).

Aldarb sits about 79 m above sea level, and its centre is roughly 18.7 km from the sea coast, so the area is inland and not on the shoreline. For floor and balcony waterproofing, this means we plan around the local climate and ground conditions rather than the constant salt spray that affects coastal homes. A balcony in this setting is exposed mainly to heavy rain runs, sun and temperature swings, and our surveys focus on how water travels across the slab and down the edges. Because the terrain is not flat, we check drainage falls and outlets as part of the initial inspection.

Each of these facts shapes the work in a practical way. The modest elevation and inland position mean water tends to pool where a slab has lost its fall, so we rebuild or confirm slopes before any membrane goes down. The distance from the coast is a reason we select coatings for ordinary rain and sun exposure rather than for salt-heavy air, and we explain that choice clearly during the quote. Where the layout includes a balcony above a living space, we treat the junction with the wall and the threshold as the key detail, since that is where leaks most often start in this part of the region.

Owners in Aldarb often make the same few mistakes, and we work to avoid them. The first is covering a cracked slab with a surface coat without injecting or sealing the crack first, which only hides the problem for a while. The second is ignoring the upturn at walls and door thresholds, so water finds its way beneath the new layer. The third is skipping a drainage check and assuming a balcony that held water last season will behave the same after resurfacing. Our site visit is designed to catch these issues before any material is chosen, so the finished floor or balcony drains as intended and stays dry at its edges.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

The following signs are worth checking before they grow:

• Damp under the light well
• A wrong fall towards the door threshold
• Water passing from the balcony to the floor below

Causes we see in the field

• A common cause: a blocked drain.
• Incorrect falls.
• A threshold without waterproofing.

Tools and methods, and when we use them

From the first visit to the report

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
