Picture an office owner in a commercial complex who notices a damp patch spreading across a balcony slab after a wet spell. Tenants are complaining, the ceiling below is stained, and the building manager wants a fix that will not disrupt daily business. For owners of offices and mixed-use complexes like this, floors and balconies are exposed surfaces that carry foot traffic, furniture, planters and drainage, so a small leak can quickly become a costly problem for everyone on the floors below.
The local setting matters here. The centre of Dumat Aljandal sits about 601 m above sea level (SRTM open elevation data), which places the town on higher ground than many coastal cities of the Kingdom. Owners should understand what this means in practice: rainfall that runs off a sloped balcony or flat commercial roof must be directed to drains rather than left to pool, and joints where balcony slabs meet walls need extra attention. Because the price of each treatment depends on the surface, a site survey before quoting helps you compare options fairly. Typical ranges for this work include bitumen membrane at SAR 15–35 per m², liquid roof waterproofing at SAR 8–25 per m², epoxy coating at SAR 35–90 per m², and crack injection at SAR 40–120 per metre.
A practical sequence keeps the work orderly. First, record where water appears and when, and check gutters, drains and outlets. Second, have the cracks and failed sealant identified, then costed by the metre where injection is needed. Third, agree the surface method suited to traffic and exposure, such as epoxy coating for heavily used floors or a membrane for balconies. Fourth, schedule the work in dry weather and plan access so tenants keep using common areas. Finally, ask the contractor for a written scope listing each area in square metres and a flood test before the area is handed back, so you can confirm the repair holds before the next rainy season.
For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
