Leak Diagnosis
Source tracing with moisture checks & test areas.
Leak diagnosis, membrane & liquid systems, injection grouting, expansion-joint sealing, and clean handover. Methods matched to substrate and Dubai climate.
Source tracing with moisture checks & test areas.
Torch-on, PU liquid, detailing & flashings.
Cementitious/PU systems with corner & pipe sleeves.
PU/Epoxy crack sealing for slabs/walls & joints.
We deliver end-to-end waterproofing — assessment, specification, substrate preparation, system installation, and QA. Methods are selected per area (roof, wet rooms, balconies, basements, tanks) to balance durability, flexibility, and cost.
We follow manufacturer guidelines and Dubai best practices — correct overlaps, upstands/downturns, terminations, and detailing around drains & penetrations for long-term performance.
Bituminous rolls with laps • Roofs/terraces • Durable.
Seamless & flexible • Complex details • UV topcoat.
Economical • Light traffic • Easy re-coat.
Wet rooms & tanks • Negative-side options.
PU/Epoxy for cracks, joints & honeycombs.
Cold-applied where torching is restricted.
Integral waterproofing via capillary blocking.
PU/MS sealants for expansion/perimeter joints.
Upstands, drains, sleeves & terminations.
Identify leak paths, damp zones, substrate condition.
Choose system for movement, UV & usage profile.
Cleaning, repairs, chamfers, primers & smoothing.
Membrane laying / liquid coats to required DFT.
Drains, sleeves, joints, terminations & upstands.
Final inspection, pond test (where safe), cleanup.
Capillary rise, façade cracks, failed external coats.
Failed wet area coat, loose drains, grout issues.
Cracked screed, poor slope, aged membrane.
Hydrostatic pressure, cold joints, honeycombs.
We specify brand-approved systems suitable for Dubai climate and the exact substrate/area.
2-part cementitious with mesh • Drains & corners detailed • Ready for tiling
Final price depends on area & prep.

Method varies by structure & access.
Get EstimateService life depends on system & exposure. Torch-on/PU roof systems typically offer multi-year durability when maintained; acrylic systems may require periodic re-coats.
Yes — warranty terms vary by system, substrate, and area. Details are included in your estimate.
In many wet areas we can apply negative-side/cementitious systems, but best results often involve re-tiling for proper layers and drain detailing.
Yes, where applicable and structurally safe, we can perform a controlled pond test before handover.
For roofs/terraces, we can integrate insulation and protection screeds where specified.
“Terrace seepage is gone after their PU system, and the upstands look neat.”

“Bathroom leak fixed without major demolition. Professional and tidy.”
— L. Costa, Downtown
“They traced the source fast and sealed expansion joints properly.”
