Before we start: what we know about Aldarb

Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).

Does a rest house or farm in Aldarb really need waterproofing for its floors and balconies? The town's location answers much of that question. The centre of Aldarb sits about 79 m above sea level, and it is about 18.7 km from the sea coast, so owners here face a dry inland climate where the main threat is water finding its way through cracks, joints and worn surfaces rather than constant coastal damp. Floors and balconies on rest houses and farms take heavy use, and a small gap can let water reach the structure below. Knowing which surfaces are exposed and how they are built is the first step toward choosing the right treatment.

Our inspection starts with a walk over every floor and balcony to look for cracks, hollow sounds underfoot, staining, and places where old sealant has pulled away. Crack injection is priced per metre, typically SAR 40–120 per m, so the inspector measures each crack and notes its length. Flat roof areas that double as balconies are checked for ponding and worn surfaces, and liquid roof waterproofing, at SAR 8–25 per m², is one option when the surface is sound but needs a fresh layer. Where a bitumen membrane (SAR 15–35 per m²) or spray foam (SAR 20–45 per m²) is being considered, the inspector records the area and the condition of the substrate underneath. Each finding is written down so the owner sees exactly what is recommended and why.

Before the visit, it helps to have a few things ready. Gather any previous waterproofing records, plans or photographs of the building, and note where you have seen leaks, damp patches or peeling paint after rain. Clear the balconies and floor areas of furniture and planters so the inspector can reach every edge and joint. If there is a water tank on the property, mention it, since tank internal coating (SAR 25–60 per m²) is a separate job that the inspector can assess at the same time. Finally, decide roughly which areas matter most to you, whether a rest house terrace used every weekend or a farm balcony that catches the afternoon rain, so the inspection can focus where it counts.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for floor & balcony waterproofing

The following signs are worth checking before they grow:

• Damp under the light well
• A wrong fall towards the door threshold
• Water passing from the balcony to the floor below

Causes we see in the field

• A blocked drain — we check this before anything else.
• Incorrect falls — we check this before anything else.
• A threshold without waterproofing — we check this before anything else.
