Before any quote is given for a restaurant floor or balcony in Alkharj, the first thing a technician checks is the ground the building sits on. The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data), which means the site is not a low-lying flood plain, so standing water is rarely the main concern. What matters more is how water moves across the surface: kitchen floors that are washed down several times a day, drains that back up, and balconies that collect rain from the roof above. Each of these shapes the choice of system, so the first checks focus on slope, drainage points, and where the existing finish has already failed.
Some things can only be settled on the site visit. The technician needs to walk the floor, test for hollow sounds under tiles, find the cracks and measure their length, and look at the edges where the floor meets walls and drains. Whether the work needs a bitumen membrane, spray foam, an epoxy coating, or a liquid system depends on what is found underneath, not on the size of the room alone. For balconies, the visit also confirms whether an XPS board layer is needed to protect the membrane, and whether any existing tiles can be lifted or must go. Pricing for each option is only firm once these conditions are known, because a crack injection job is charged per metre while a coating is charged per square metre.
To help the technician arrive prepared, it is useful to have a few details ready before the visit. Note the area of the floor or balcony in square metres, the length of any visible cracks, and whether the restaurant runs a kitchen, a seating area, or both. Mention when the floor was last resurfaced and whether leaks have been seen below, in a storeroom or on a lower level. If the balcony is open to rain, say which direction it faces and whether a roof sits above it. Clear photos of the surface and the drains help the technician plan the work and reduce surprises on the day.
For restaurants, visits are planned outside service hours and recorded for the premises file.

Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| 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 |
From the first visit to the report

Common questions about floor & balcony waterproofing in 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.
