FAQ
Failed membranes at drains, parapets and AC penetrations, ponding from poor falls, UV-aged acrylic coats, and thermal movement that opens laps. Ceiling stains often appear far from the entry point because water travels through screed.
Local repair suits a single failed outlet or parapet when the surrounding membrane is sound. Multiple drip points, widespread blistering or end-of-life chalking usually need broader strip-out. Inspection decides — not a phone estimate.
New roof waterproofing installs the first barrier on a new-build deck before finishes. Repair finds why an existing system failed and remediates it, often with strip-out on occupied buildings. Mixing the two scopes wastes money.
Exposed villa roofs often use liquid polyurethane or polyurea with UV-stable topcoats. Covered podiums may use bituminous build-ups. Metal warehouse decks need seam and fastener programmes. Substrate and exposure drive the choice.
Properly specified and maintained systems often last many years. Thin decorative coats without prep may fail within a few summers. Lifespan tracks drains, detailing and maintenance more than brochure claims.
Often yes. Drains set high relative to finished falls cause ponding that finds every defect. A serious scope reforms outlets and reinforces fabric at every penetration.
Usually yes with interior protection and phased access. Method statements should state noise windows, dust control and reopen times after coating cures.
Inspection findings, strip-out assumptions, primer, membrane thickness, reinforcement, parapet and drain detailing, penetrations, testing, warranty terms and exclusions. Field coat per square metre alone is incomplete.
Metal roofs fail at fasteners, seams, gutters and skylights under thermal movement. Villa concrete roofs fail at membranes, falls and wet details. Do not apply a villa liquid quote to a corrugated logistics deck without a metal survey.
Not automatically. Some systems combine waterproofing and heat reduction; others only reflect heat. The written scope must state whether you are buying water resistance, heat reduction or both.
When the source is unclear, stains recur after a prior patch, or opening finishes would be expensive if you choose wrong. Detection maps paths before strip-out.
Expect a written local warranty for treated areas against water ingress through specified paths, with exclusions for blocked drains, new penetrations and third-party damage. Ask what maintenance keeps cover valid.
Treat it as an early warning. Water may already be travelling through the slab. Early detail repair costs less than full interior reinstatement after mould and electrical risk grow.
They must be detailed. Pads and pipe sleeves often pierce membranes. Units may be lifted onto temporary supports or resealed on new plinths. Leaving penetrations undocumented causes repeat leaks.
Yes. DryGuard.ae works across Sharjah, Ajman, Abu Dhabi, Ras Al Khaimah and other emirates. Access equipment and logistics are included in the programme for each site.
