An owner of a company premises in Samtah, such as a small office block or a workshop with staff washrooms, usually wants bathroom waterproofing handled once and then kept under control. Rather than calling a contractor each time a tile lifts or a wall shows damp, the owner signs an annual contract so that inspections, minor repairs and recoating are planned around the working year. The aim is fewer interruptions for staff and no surprise bills when water starts appearing behind a wall.

The local facts give this planning some useful context. The centre of Samtah sits about 61 m above sea level, and the town is about 22.6 km from the sea coast. For a bathroom, this means the site is not a low-lying coastal plot where ground water is always close to the surface, so the main risk is usually water moving through the building from the bathroom floor and wall joints rather than from the ground. An annual contract suits this pattern well, because the contractor can check the same joints, drains and corners each year and treat them before they fail. Bathroom waterproofing is typically priced at SAR 15–40 per m², and spray foam or liquid systems at SAR 8–45 per m² depending on the method, so a company can budget a fixed yearly figure that covers the whole washroom block.

Practical steps for the owner run in a clear order. First, ask the contractor to survey every washroom and list the areas that need work, including floor-to-wall junctions, shower areas and any cracks. Second, agree on the method for each area, such as a membrane for floors, a coating for walls, or crack injection at SAR 40–120 per metre where a line of cracking is found. Third, set the yearly visit schedule and confirm what is included, so that minor touch-ups are not billed separately. Fourth, keep a simple log of any leaks reported by staff and share it with the contractor at each visit. Finally, review the contract each year against the log and adjust the scope before renewal.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
