Basement & foundation waterproofing in Aldiriyah: for companies (annual contract)

Before we start: what we know about Aldiriyah

Team note on Aldiriyah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data).

For companies with basements or foundations in Aldiriyah, the most common problem is water seeping through the lower walls and floor slab after rain or when groundwater rises. Cracks in concrete, poorly sealed construction joints and failed old coatings let moisture in, and for an office or warehouse this can damage stored goods, ruin finishes and create conditions that affect staff. Our first job is to find where water is entering, not simply to paint over the damp patch.

Aldiriyah sits at roughly 655 m above sea level, and that local fact shapes how we approach each site. Sites at this elevation often see sharp temperature swings and occasional heavy rainfall that runs off hard ground toward low-lying structures, so surface water can build up quickly around a basement. Because the approach must match the way water actually moves through the ground and the structure, we look at drainage, slope and wall condition together. For basement walls we typically consider options such as bitumen membrane, which sits in the SAR 15–35 per m² range, XPS boards at SAR 12–30 per m², or a full basement system at SAR 50–150 per m². Where a single crack is the source, crack injection is priced at SAR 40–120 per metre, and a sealed foundation may also need spray foam at SAR 20–45 per m² or epoxy coating at SAR 35–90 per m².

Before the visit, ask us a few clear questions so the survey can be planned properly. Tell us the approximate area of the basement or foundation, when water was first noticed, and whether it appears after rain, from groundwater or from a plumbing leak. Share any previous repair work, drawings or photographs you have, and note whether the space is in use, since that affects access and scheduling. Ask us to explain how the proposed method will be checked after installation, and request a written scope with the unit rate for each item so your budget can be compared line by line. This keeps the site inspection focused and gives your team a clear picture before any work begins.

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

When do you need basement & foundation waterproofing?

These are the signs most often linked to basement & foundation waterproofing:

• Water seeping in after rain
• Salt marks at the bottom of the walls
• Damp basement walls

The most common causes

• Cracks at construction joints — we check this before anything else.
• A high groundwater level.
• Rainwater draining towards the foundation.

Tools we use in Aldiriyah

How the work is done, step by step

1. Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
2. Preparation: Surfaces are cleaned and opened where needed.
3. Injection: Active cracks are injected.
4. Waterproofing layers: The system is applied on the right side of the wall where possible.
5. Follow-up: Readings are repeated after the treatment.
