Is a leaking floor or balcony an emergency in Alahsa, and what will it cost to fix? A leak through a slab or balcony can spread quickly into finishes below, so it is worth acting fast. The centre of Alahsa sits about 152 m above sea level (SRTM open elevation data), which is a useful reminder that the area is not at risk of the low-lying flooding seen in coastal towns, so water entering your floor usually points to a membrane or joint failure rather than the ground around the building. Costs depend on the method and the area involved. Crack injection is priced at SAR 40–120 per metre, spray foam at SAR 20–45 per m², epoxy coating at SAR 35–90 per m², and bitumen membrane at SAR 15–35 per m². Bathroom waterproofing runs SAR 15–40 per m², while liquid roof waterproofing is SAR 10–25 per m².
When the visit is booked, the inspection usually starts by tracing where the water is coming from. The technician will look for cracks, failed joints and areas where the existing coating has lifted, and will note which surfaces are affected, such as a bathroom floor, a balcony slab or a section of roof above a living space. Where a crack is the cause, the team can measure its length, since crack injection is charged per metre. For wider or flat areas, the surface is measured in square metres so the right system can be matched to the job, whether that is a liquid coating, a membrane or spray foam. The aim of the inspection is to find the source of the leak first, so that the repair treats the cause rather than only covering the symptom.
To make the visit as quick as possible, clear the area around the leak and move furniture, rugs and stored items away from the floor or balcony. Take photographs of the staining, cracks or damp patches and note when you first noticed them and whether they grow after rain or after using water nearby. If you have any earlier waterproofing invoices or details of the materials used, have them ready, along with the approximate size of the affected area in square metres. Keep access open to the roof or balcony and tell the technician about any tiles or finishes that must be protected during work.
If water is flowing, close the main valve first, then call or message with photos.

Common questions about floor & balcony waterproofing in 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.
