Floor & balcony waterproofing in Allith: before summer & rain season
In short: Floor & balcony waterproofing (before summer & rain season) in Allith starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Allith sits about 5 m above sea level (SRTM open elevation data). Published price: Bathroom waterproofing (per m²), SAR 15–40 per m²; anything else is quoted after the inspection.
Before we start: what we know about Allith
The centre of Allith sits about 5 m above sea level (SRTM open elevation data). Allith is about 1.2 km from the sea coast (OpenStreetMap).
Main roads in or near Allith: Al Laith Road, Amr Bin Al Aas Street.
Consider a homeowner in Allith with a flat concrete roof terrace and a first-floor balcony that has started to show faint staining on the ceiling below. Their property is typical of the area: a few years old, with the usual exposure to strong sun in the warmer months and occasional heavy downpours in winter. They want to act before the next season rather than wait for a leak to appear inside the living room.
The local facts matter here. The centre of Allith sits about 5 m above sea level, so rainwater tends to drain away rather than pool in low ground, but a flat roof or balcony with a poor slope will still hold water in its own surface depressions. Allith is also about 1.2 km from the sea coast, which means salt-laden air can reach the surface of exposed concrete and sealants over time, speeding up wear on joints and coatings. For an owner, this points toward choosing a membrane or coating that stays flexible and resists both UV and salt, and toward checking joints and cracks before the rains arrive rather than after.
A sensible sequence starts with a dry inspection. Walk the roof and balcony after a rain and note ponding, hairline cracks, and any lifted or cracked old sealant around drains, parapets and door thresholds. Mark crack lines in chalk, since a crack that runs in a straight line is often the first point of entry. Next, plan the repair. Cracks wider than a hairline can be treated with crack injection, priced per metre, and small defects can be sealed before the main coating goes on. Then decide the surface system. Liquid roof waterproofing suits most open roofs and balconies, while a bitumen membrane may suit heavier-use areas, and the choice should follow the surface and the budget for each square metre. Finally, check the work by ponding a small area with water for a day and confirming that nothing reaches the ceiling below before the summer heat arrives.
Checks before summer and before the rain season catch problems while they are still small.
Signs worth paying attention to
The following signs are worth checking before they grow:
- Water passing from the balcony to the floor below
- A wrong fall towards the door threshold
- Damp under the light well
Causes we see in the field
- A threshold without waterproofing.
- A common cause: incorrect falls.
- A blocked drain.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Allith |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| 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 |
From the first visit to the report
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.
