Floor & balcony waterproofing in Alahsa: before buying or handover
In short: Floor & balcony waterproofing (before buying or handover) in Alahsa starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Alahsa sits about 152 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.
Floor & balcony waterproofing in Alahsa: the local context
Team note on Alahsa: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Alahsa sits about 152 m above sea level (SRTM open elevation data).
The centre of Alahsa sits about 152 m above sea level (SRTM open elevation data), which means the city is a broad, low-lying oasis rather than a hilly town. For floor and balcony waterproofing, the practical effect is that water collects and stands in low spots rather than draining off steep slopes, so a properly falling floor and a clear outlet matter more here than gradient alone. Before any work is priced, the installer should check where rainwater and washing water will travel across a balcony and confirm that the finish directs it toward the drain, not back toward the wall.
Pricing reflects the materials and the surface, so owners should compare quotes on the same basis. Basement waterproofing (per m²): SAR 50–150 per m² costs more than the other systems because it deals with ground moisture and pressure. Bathroom waterproofing (per m²): SAR 15–40 per m² and epoxy coating (per m²): SAR 35–90 per m² cover wet floors, while liquid roof waterproofing (per m²): SAR 10–25 per m² and bitumen membrane (per m²): SAR 15–35 per m² suit exposed roofs and balconies. Spray foam (per m²): SAR 20–45 per m² and XPS boards (per m²): SAR 10–30 per m² are used where insulation is also wanted. Crack injection (per metre): SAR 40–120 per m is priced by length, so a survey of the cracks gives a realistic figure. Tank internal coating (per m²): SAR 25–60 per m² applies only where water is stored.
Before buying or handing over a property, owners commonly avoid several mistakes. They do not accept a quote that names a material without stating the area, since the per-m² rate is only meaningful against a measured surface. They do not skip the crack check, because injection priced per metre is cheaper than repairing damage that spread. They do not assume a bathroom system will also protect an exposed balcony, and they do not hand over a site until the falls and drains have been tested with water. Asking for the coating thickness and the cure time in writing also prevents disputes later.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.

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

Questions from Alahsa
Is it possible to unclog drains without breaking the floors?
In most cases, yes: camera inspection and high-pressure water jetting clear the blockage from drain openings and inspection chambers without breaking anything, except when there is an actual break in the pipes.
Does renovation include treating dampness and insulation?
Usually yes, since dampness treatment is an essential part of renovation, especially in Al-Ahsa. The contractor identifies the source of the leak and then carries out the appropriate insulation. Mention the dampness problem in your request description.
What is the difference between foam insulation and roll insulation?
Foam is sprayed on as a continuous layer with no seams and provides both thermal and water insulation, while rolls are separate pieces that require joining and mainly focus on water insulation.
