Floor & balcony waterproofing in Alkharj: preventive periodic check
In short: Floor & balcony waterproofing (preventive periodic check) in Alkharj starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened.

The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data).
The centre of Alkharj sits about 439 m above sea level, which places the city on a broad plateau in the interior of Saudi Arabia rather than in a low coastal basin. For floor and balcony waterproofing, elevation matters less for the rain itself than for how surfaces are exposed to strong sun, dry heat and sudden temperature swings. Concrete slabs and balcony floors expand and contract through the day, and that movement is one of the main reasons hairline cracks open over time. Our preventive, periodic approach is designed around that daily cycle, so that small openings are sealed before they can carry water into the layers below.
Each part of the job is matched to what the surface actually faces. Balcony and floor coatings are chosen by exposure, with liquid roof waterproofing typically priced between SAR 8 and SAR 25 per m², bitumen membrane between SAR 15 and SAR 35 per m², and epoxy coating between SAR 35 and SAR 90 per m² where a harder wearing finish is needed. Where a balcony edge or joint shows movement, crack injection is quoted per metre at SAR 40 to SAR 120 per m, because a sealed crack is far cheaper than repairing the water damage it lets in. Heat-exposed areas may also benefit from XPS boards at SAR 12 to SAR 30 per m², which help limit how much the surface moves. The aim is a plan that fits the actual slab, not a single product applied everywhere.
Owners in Alkharj often make the same avoidable mistakes. The most common is waiting for a visible leak before inspecting, since water can travel along a slab for weeks before a stain appears below. Others skip cleaning and drying the surface, which stops any coating from bonding properly, or apply a thick layer in direct midday sun, which causes it to cure unevenly. Some owners also treat balconies as decoration and ignore drainage outlets that have silted up, leaving water to pool at the edges. Periodic checks, timely crack sealing and proper surface preparation prevent most of these problems and keep the cost of upkeep low over the years.
Preventive checks follow a written schedule instead of waiting for a fault.

| Tool | What it finds | When we use it in Alkharj |
|---|---|---|
| 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 |

Short answers for Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
