Water tank sealing in Al Basatin Jeddah
Al Basatin is a modern residential district where large luxury villas sit on generous plots and closed residential compounds dominate. Water tanks in these large villas face high pressure from heavy use by large families, swimming pools and landscaping. Leaks begin as small cracks in the floor and the joints between walls and floors.

How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.
-
Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Basatin
Villas and compounds here were built in recent years and tanks were constructed in standard concrete without modern waterproof coatings. The method is set out in full on the full Water tank sealing page.
Large and deep villa tanks
Villas in Al Basatin have large tanks holding 10-20 cubic metres or more, built beneath floor slabs or above roof lines. Heavy use from pools, gardens and large households puts constant stress on the internal lining.
New concrete needs modern sealing
Most tanks here were built 5-15 years ago and concrete ages and cracks under thermal expansion in the hot climate. Basic paint coatings offer poor protection against fine cracks.
Pools and gardens drive continuous water demand and pressure
Many villas have pools or large gardens needing daily water. The constant demand places steady pressure on tank walls and floor.
The character of Al Basatin
Villa district: private plots, gardens and a boundary wall to every house
Large villas in Al Basatin have large, complex underground and roof tanks. Sealing must account for the villa's structural design and withstand heavy daily demand from multiple water uses.
What we read before any material is opened
A modern residential district in north Jeddah between the Al Murjan seafront and Madinah Road, with large villas on spacious plots and modern residential compounds, bounded by King Abdulaziz Road and Prince Sultan Road.
Cracking in the wall
Floor inspection reveals fine cracks and moisture seeping inward from outside sources.
The floor to wall joint
Joint inspection between walls and floor detects erosion of seals and water escape from tank corners.
The condition of the old lining
Pipe entry inspection identifies weak points around pipe openings and penetrations.
Sediment and scale
Constant coastal moisture and heat cause concrete and lining to crack faster than in drier regions.
The pipe entries
Old lining loses adhesion, begins to peel and taints water with paint particles.
The hatch and the vent
Algae and bacterial growth occur if cracks allow water infiltration.
How we work
-
1
Inspect with the tank empty
We drain it and read the surface dry: whether the water leaves through a crack, a joint or a pipe collar, and what the outer face of the wall and the ceiling below are telling us. A level test with the valves closed separates a leaking tank from leaking pipework.
-
2
Clean and prepare the substrate
Sediment out, a high pressure wash, the loose old lining and the weak surface layer of the concrete taken back, then dried. The material grips sound substrate and nothing else.
-
3
Make the cracks and joints good
Cracks are chased out and filled with a repair mortar, a cove is formed where the floor meets the wall, and every pipe collar is treated on its own.
-
4
Lining, fill test, sterilisation
Successive coats, each run across the one beneath it, on the face the water touches. Then a full cure, a fill with the level watched, and sterilisation with the first fill run to waste before the tank returns to use.
What water tank sealing includes
-
Finding where the water leaves
Carried out drained and dry: cracks, joints, pipe collars and the outer face of the wall.
-
Draining and sediment removal
The last of the water and the settled layer on the floor come out, because a lining does not stick over sediment.
-
Cracks and joints made good
The crack opened and filled, a cove formed at the floor to wall junction, and each pipe entry worked separately.
-
Lining coats on the water face
More than one coat, each crossing the one below, in material made for drinking water tanks rather than roof waterproofing.
-
Curing, fill test and sterilisation
The material is left to cure, the tank is filled and the level watched, then sterilised and the first fill run to waste. How long the cure takes follows the material and the weather, and we tell you before the date so you can plan around the supply.
-
A follow-up level check
We come back once it is in service to read the level and check the outer face, because any remaining loss shows up then rather than on the day of the work.
What is different about Obhur Sub-Municipality
Obhur sub-municipality runs along Jeddah's northern shoreline from Al Shati up to Obhur Creek. It mixes large villas and gated compounds with busy commercial spines of restaurants, cafes, markets and hotels. Sea humidity is high for most of the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround the corniche and the villa plots. Standing irrigation water, dense planting and food waste from the hospitality strip suit cockroaches, mosquitoes and ants, and the chalets and rest houses scattered along the creek stand empty for long spells, which lets insects and rodents settle undisturbed.
Questions about this district
Do fine cracks in villa tanks pose health risks?
Yes. Cracks allow bacteria, moisture and contamination to enter from outside. Water loses purity and becomes a health hazard.
Should minor leaks from a tank be treated at once?
Yes. Even small leaks signal weakness in the lining and cracks expand over time under pressure.
How often does a villa tank need sealing?
If sealed correctly with modern lining, it lasts 10-15 years. Annual inspection is essential.
Can a tank be sealed without complete emptying?
No. Modern lining requires full access to all surfaces and deep cracks must be reached.
Why do new villas in Al Basatin need sealing after only a few years?
New concrete cracks from thermal expansion and water pressure. Initial coating is insufficient for the heavy demand.
Does extreme heat affect tank lining durability?
Yes. High heat causes concrete and lining to expand, widening cracks and increasing leaks.
How much does water tank sealing in Al Basatin cost?
It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Basatin.
