Repair & General Maintenance in Abu Dhabi Corniche

The first call on any repair brief is diagnosis. Once the defect is named, the system family becomes obvious.

• Crack injection

  Epoxy (structural restoration) or PU (flexible / leaking cracks). Packer system, photo-documented per joint.

• Concrete spall repair

  Chip-back, rebar treatment, Mapei Planitop polymer-modified repair mortar, finish to match.

• Corrosion treatment

  Galvanic anodes, corrosion inhibitor, passivation. Half-cell potential mapping before and after.

• Structural strengthening

  CFRP wrap (Mapewrap carbon fibre), steel-plate jacketing, micro-concrete. Engineer-signed scheme.

• Soil stabilisation

  High-pressure resin injection for ground stabilisation behind retaining walls and below foundations.

• General maintenance

  Annual inspection, snag closure, periodic re-coating, condition reports. Maintenance contracts available.

• When is a crack structural vs cosmetic?

  Structural cracks typically: width > 0.3 mm, propagate through full element thickness, active under load, often diagonal. Cosmetic cracks: width < 0.2 mm, surface-only, often pattern (shrinkage) cracking. We measure width with a crack gauge and core-sample where the cause isn't obvious from the surface.

• Epoxy injection vs PU injection — which?

  Epoxy for structural cracks in dry concrete — it restores monolithic strength. PU expanding injection for active leaks or moving cracks — it stops water and flexes with movement. Often we use both: PU first to stop the leak, epoxy second to restore strength.

• How do I know if rebar is corroding behind the surface?

  Three tests: half-cell potential (electrical reading at the surface), cover meter mapping (locates rebar and measures concrete cover), and carbonation depth (acid-base test on a fresh core). Together they tell us whether the rebar is actively corroding even before spalling is visible.

• What's CFRP and when is it used?

  Carbon Fibre Reinforced Polymer — a thin, high-strength fabric or laminate epoxied to the concrete surface to add tensile capacity. Used when a structural element needs strengthening (e.g. load increase, deterioration) and adding more concrete or steel isn't practical. Faster, lighter, more expensive. Engineer-designed every time.

• Will the repaired patch match the surrounding concrete colour?

  Usually no — repair mortars have a different binder mix and age at a different rate. We can apply a coloured finish coat or full elevation paint after the repair to disguise the patches. Cosmetic matching is part of our scope when called out in the brief.

• Can you stop a live leak from a basement crack?

  Yes — high-pressure PU expanding injection through packers drilled into the crack. The PU expands when it hits water and seals the crack from the inside. Sometimes followed by epoxy injection in dry conditions to restore strength. We've done this on tier-1 hospitality basements in active leak conditions.

• Annual maintenance contracts — what's included?

  Typically: quarterly visual inspection, annual NDT scan on critical elements, snag closure of routine cracks and spalls, condition report with photos, recommendations for the year ahead. Bespoke per portfolio — we scope to what the FM team needs.

• How quickly can you mobilise for an emergency?

  24–48 hours for an active leak or live structural concern in Dubai / Sharjah / Abu Dhabi. Same day where access is straightforward. Diagnosis first, fix second — we don't pile materials onto a problem before we know the cause.

• Do you provide engineering reports?

  Yes — for structural repair scopes we provide a chartered engineer's stamp on the root-cause report and the repair scheme. Required for insurance, refurbishment permits and litigation. Optional for cosmetic repairs.

• Cost — how is it estimated?

  Three components: diagnosis (NDT survey + report — typically AED 4,000–18,000 depending on scope), repair (per element type and area — quoted after diagnosis), and engineering (where required, AED 6,000–30,000 for a stamped scheme). We quote diagnosis separately so you can decide on the repair scope with data in hand.

• Waterproofing

  When repair reveals a failed membrane upstream.

• Insulation

  Combined remedial works on roofs and metal envelopes.

• Specialised Coatings & Sealants

  Joint sealing where movement is the underlying cause.
