A leaking tank wastes water, damages roofs and can put water quality at risk. Most can be fixed without replacement.

Overview
ESA Technical Services LLC is a Dubai-based technical services company, established in 2006, specialising in GRP works, waterproofing, insulation and installation across the UAE. GRP water tank services are among our most requested works, for residential towers, villas, hotels, hospitals, schools and industrial sites.
GRP sectional (panel) tanks are assembled from moulded GRP panels bolted together with sealant in the joints and internal or external steel or GRP stays. Moulded one-piece tanks are also common on villas. Both are durable and hygienic, but over years of heat cycling, pressure and vibration, joints, sealants and bolts can start to leak.
Our tank rectification service repairs those problems properly. We find the source, repair with materials suitable for potable water, and prove the result with a fill test. For new tanks, see our GRP panel tank installation service.

Replacement is disruptive and expensive. This is how we decide, and how we'll explain it to you after inspection.
| Condition | Typical recommendation | Why |
|---|---|---|
| Leaks at panel joints, bolts or sealant | Rectify | Local re-sealing and joint lamination restore watertightness |
| Hairline cracks or local panel damage | Rectify | Grinding and GRP patch lamination restore the panel |
| Many leaking joints, sound panels | Rectify (internal re-lamination) | A continuous internal laminate over the joints can seal the whole tank |
| Corroded internal steel stays | Rectify (replace stays) | Stays can be replaced with GRP or protected steel |
| Badly deformed, brittle or delaminated panels | Replace panels or tank | The structure can no longer safely carry the water load |

FAQ
Many joint and bolt repairs are completed within one to a few days, including draining, repair, curing and refilling. Larger internal re-lamination takes longer. We plan the work to keep water outages short, for example by working compartment by compartment where the tank is divided.
Yes. For potable water tanks we use resins and sealants suitable for drinking-water contact and follow full cure times before refilling. We coordinate cleaning and disinfection so the tank returns to service in a hygienic condition.
Minor external leaks can sometimes be temporarily sealed, but a permanent GRP repair needs a dry, clean, prepared surface. We usually drain the affected tank or compartment and plan the timing with you.
Yes. See our GRP panel tank installation service for new sectional tanks, including base frames, assembly, stays, sealing and fill testing.
