Checking and assessing the crack
We check the crack for depth, direction and whether it sits at a joint or across the slab, because that guides the repair method.
- 3
Opening the crack and preparing the surface
The crack is opened evenly to remove dust and broken edges from inside, and the surrounding surface is cleaned before any treatment.
- 4
Filling and waterproofing
The crack is filled with a flexible material that moves with the concrete without cracking, then the surface is waterproofed to stop rainwater entering.
A proper repair starts from the crack itself
- We open and clean the crack before any filling
- The flexible material handles concrete expansion and contraction
- Treating the crack first protects the waterproofing layer above
- We take your request by phone call or WhatsApp message
- We explain the problem to you before we start work
The service in Az Zahrah District
In a district like Az Zahrah where homes and villas are close together and roofs are flat with tanks and joints, cracks usually start small at joints and corners then widen due to heat and damp swings. Buildings in the area face pressure from salts and damp from below, making concrete more prone to cracking. The first inspection determines the crack's extent, depth and whether water is leaking through, then the joint is cleaned, filled with a flexible material and sealed with a strong waterproof layer.
Az Zahrah District is in Al-Ahsa governorate in the Eastern Province, close to Al Jamiyin District, Al Iskan 1st District and Al Hamra 1st District.
Ring-shaped cracks around roof tank bases are riskier than straight cracks, because they spread water over a wider area underneath the roof.

Questions about Roof crack repair in Az Zahrah District
A hairline crack usually stays on the surface of the slab and often comes from repeated expansion and contraction or from early concrete shrinkage. A deeper crack goes through the slab and lets rainwater pass inside. Both need repair, because a hairline crack widens with every rainy season if it is left untreated.
The intense heat expands the concrete surface by day and contracts it at night and in winter. This repeated movement stresses the concrete and opens cracks over time, even without rain. Expansion joints are designed to absorb this movement, but they also need regular maintenance.
Filling the crack closes the visible gap, but the slab surface around it stays exposed to rain. Rainwater finds other paths through the concrete pores or at the parapet edges. So the repair is complete only when the surface is waterproofed after the crack is filled, not before.
A damp patch on the ceiling appears or grows after rain and dries out in dry summer months. It is often below a visible crack on the roof or close to the parapet wall. If the damp appears at any time regardless of rain, the source may be something else and it is worth checking.
Tell us where the crack is on the roof, whether it is in the middle of the slab, near the parapet or at a joint, and whether damp shows on the ceiling below. If the crack is old and was repaired before, let us know that too. It helps to describe it clearly so we can assess what the job needs before we visit.
A dangerous crack is one that lets water or damp in, widens quickly, or is surrounded by damp stains on the ceiling. Very fine cracks in the outer layer only may be harmless, but doubt calls for inspection.
Note the crack's exact location, estimate its length, check the room below for damp stains or water, take a clear photo of the crack and surrounding area, and send it on WhatsApp when you call.
