Roof Rehabilitation & Roof Waterproofing Solutions UAE
Roof rehabilitation is the process of repairing, upgrading, and restoring existing roof waterproofing systems that have deteriorated due to age, water leakage, ponding water, UV exposure, thermal movement, failed coatings, or membrane deterioration. Rather than replacing the entire roof, rehabilitation focuses on identifying the root cause of failure, repairing damaged areas, and installing a suitable waterproofing system to extend the service life of the roof and improve long-term performance.
Common applications include commercial buildings, industrial facilities, warehouses, podium decks, utility structures, and infrastructure projects across the UAE.

Roof rehabilitation process.
- 01
Site inspection
Every rehabilitation begins with a documented site inspection: water-ingress mapping, infrared thermal imaging where required, core sampling to identify substrate condition, and assessment of existing membrane chemistry to inform compatibility of overlay systems.
- 02
Surface preparation
Surface preparation is the single largest determinant of long-term performance. We remove failed coatings and contaminants by diamond grinding, shot blasting, or vacuum-assisted scarifying, then verify substrate moisture, pH, and profile before priming.
- 03
Concrete and substrate repair
Spalled and delaminated concrete is removed and reinstated with EN 1504-compliant polymer-modified repair mortars. Exposed reinforcement is cleaned, passivated, and re-cover-checked. Substrate levels are corrected before the overlay membrane.
- 04
Joint, crack, and detail treatment
Construction joints, movement joints, and dormant cracks are detailed with reinforcement bands, sealants, and where required, polyurethane injection — establishing a continuous waterproof envelope before the main membrane is applied.
- 05
HVAC, drain, and penetration detailing
HVAC kerbs, drain bowls, parapet upstands, and pipe penetrations are detailed with reinforced corner bands and elastomeric flashings. Every penetration is treated as a discrete waterproofing detail with documented method.
- 06
Replacement waterproofing systems
Where existing membranes are beyond rehabilitation, we strip back to substrate and install replacement systems — bitumen membrane, liquid polyurethane, or polyurea — specified to the asset class, exposure, and service life requirements.
- 07
QA / QC and warranty
Every project is documented end-to-end: substrate logs, primer DFT, membrane DFT, adhesion pull-off testing, holiday detection, and flood testing where applicable. Project warranty is issued on handover with the full QA record.
