Roof Rehabilitation Systems
TEXSA specializes in rehabilitation of failed roofing systems using advanced waterproofing technologies, concrete repair, surface preparation, and protective coatings engineered for long-term performance in the UAE climate.
End-to-end roof rehabilitation.
Failure diagnosis
Every rehabilitation begins with a documented site survey: 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.
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.
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.
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.
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.
Pure polyurea rehabilitation overlay
Hot-spray pure polyurea is the primary overlay system — applied by GRACO Reactor as a seamless, fast-cure, fully-bonded membrane that bridges existing substrate movement and returns the roof to service within hours of application.
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.
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.
