About This Service

Water tanks fail in two directions: they leak water out through cracks and joints, and they let contamination in through degraded internal surfaces. We reline concrete and GRP tanks with potable-approved, food-grade coating systems that seal the structure and give a smooth, cleanable internal surface that meets municipal requirements.

We handle underground and overhead tanks for villas, buildings, and commercial facilities, working around your water supply schedule so the outage is as short as possible.

What’s Included

Tank relining is a controlled process from drain-down to refill.

  • Tank drain-down, cleaning, and surface assessment
  • Crack and joint repair with potable-approved materials
  • Food-grade internal coating system
  • External waterproofing for underground tanks
  • Curing, wash-down, and disinfection
  • Refill support and leak verification

Key Benefits

Potable approved

Only food-grade, drinking-water-safe coating systems are used inside tanks.

Short outage

Most villa tanks are relined and back in service within three to four days.

Cleaner water

Smooth new internal surfaces resist algae and sediment build-up.

Both directions

We stop leaks out of the tank and contamination into it in one job.

Questions We Get Often

Is the coating safe for drinking water?

Yes. We use potable-water-approved systems specifically certified for contact with drinking water, and the tank is washed and disinfected before refill.

How long will we be without the tank?

Typically three to four days for a standard villa tank including curing. For buildings we can often stage the work tank by tank so supply is never fully off.

Our underground tank fills with groundwater. Can you fix that?

Yes. That is external ingress and we treat it with injection sealing plus an internal system rated for negative pressure.
