How we work

From your call to the sealed crack

  1. 1

    Describe what you see

    Call or message us on WhatsApp and tell us where the crack is, what it looks like, and whether it is widening or dampening the nearby wall.

  2. 2

    We diagnose type and cause

    We tell apart a surface shrinkage crack, a deeper structural crack, and a crack that lets water through, because each has a different repair.

  3. 3

    We choose the repair method

    The repair may be injection with resin or cementitious grout, opening the crack and filling it, or patching with a flexible material that absorbs movement. The nature of the crack determines what it needs.

  4. 4

    We treat and finish the surface

    After the crack is treated, the area is prepared and levelled to receive paint, plaster or any finishing layer.

Questions

Questions about Concrete injection & crack repair

A fixed hairline crack that does not change with the seasons is often a surface shrinkage crack. A crack that widens in heat, shows damp, or runs diagonally between courses deserves a check, as it may point to structural movement or a water entry point.

Injection reaches inside the crack with a liquid or semi-liquid material that fills the voids from within and stops movement or water entry. Patching treats the surface after opening and cleaning the crack, then filling it with mortar or a flexible material. The choice depends on the crack's depth, nature and position.

Yes, but the treatment differs. A crack in plaster may come from drying too fast or the layer separating from the wall behind, and repair starts by finding hollow areas and re-plastering. A crack in concrete may need injection with a suitable material to close it from within.

Yes, because an external wall faces more sun, rain and heat movement. A crack there lets water in directly and is often accompanied by peeling paint and plaster. The repair covers closing the crack and then protecting the surface to stop water re-entering, unlike an internal wall that does not face the same outdoor conditions.

A roof slab faces a wider temperature range between day and night, so the concrete expands and contracts more than a wall does. Cracks there let rainwater through directly to the top floor. Repair starts by opening the crack and filling it with a flexible material that absorbs movement before any waterproofing layer above.

Tell us where the crack is, whether it is in an internal wall, an external wall or the roof, whether it runs horizontally, vertically or diagonally, whether you see damp or peeling nearby, and whether you have noticed it widening over time. These details help us identify the crack type before we visit.

Injection suits cracks that go deep but are too narrow to fill by surface patching. A hairline crack with real depth can be injected with a liquid material that penetrates and fills it. A surface crack in plaster usually does not need injection and is treated by opening it and refilling.
