What does concrete tank insulation cover?
A concrete tank takes more stress in the climate than most materials. The intense summer heat expands the concrete, the cooler nights contract it, and the repeated cycle works on the joints between panels and along the walls. The crack starts as a hairline and widens over time, sometimes appearing first as a damp patch on the ceiling or wall below the tank rather than as visible water.
Tell us what you notice in your concrete tank, which district you are in, and whether the tank sits on the roof or below it, and we agree a time. We inspect the walls, floor, ceiling and joints, and carry out the insulation from start to finish.
These are the parts the work goes through in a concrete tank, depending on its condition and where the leak or seepage is found.
- Interior walls
The interior concrete walls are checked for cracks and porosity, cracks are treated, and the insulation layer is applied across the full surface to stop seepage.
- Tank floor
The tank floor bears the weight of water constantly and is especially prone to cracking; we treat it with the right insulation to prevent water moving downward.
- Tank ceiling
The concrete ceiling of a rooftop tank faces direct sun, which speeds up cracking; we insulate it to stop seepage and reduce heat transfer to the stored water.
- Panel joints
The joints between concrete panels are the first place water escapes, as they move with expansion and contraction; they are treated with a flexible filler that seals the gap and absorbs movement.
- Concrete cracks
Existing cracks are cleaned before filling, because any dust or deposit left inside stops the insulation bonding to the concrete and shortens its life.
- Openings and entry points
The edges of drainage and feed openings and pipe entry points are weak spots in a concrete tank and are treated carefully, as water finds its way through them quickly.

Tell us about the tank
Tell us what you see, whether visible cracks, damp on nearby walls or water loss, whether the tank is on the roof or in the ground, and which district you are in.

Agree a time and prepare
We settle on a time that suits you, and you empty the tank before the appointment and keep it dry, because working on dry concrete is what allows the insulation to bond to the surface.

We work and you check after
We inspect the walls, floor and joints and apply the insulation, then you fill the tank after the interval we give you and check that the seepage and water loss have stopped.

Questions about Concrete-tank insulation
I see a damp patch on the ceiling below my concrete tank, is that a leak?
Yes, it is usually a leak from the tank floor or from a joint between concrete panels. Concrete is naturally porous and water works its way slowly through fine cracks before the damp patch appears below. The longer it is left, the wider the patch spreads and the more it affects the structure.
How do I prepare for my concrete tank insulation appointment?
Empty the tank completely and let it dry before the appointment. If the tank is sealed or hard to reach, tell us when you call so we can plan for it. A fully dry tank allows the insulation to bond to the concrete correctly.
Does the job change if the tank is large or has multiple sections?
Yes, the surface area and any internal dividing walls affect the scope of the work. Each dividing wall has its own joints and floor junctions that need insulation. That is why we ask about the tank's dimensions and layout when you call.
What should I check after the concrete tank insulation is done?
After the drying interval we give you, fill the tank gradually and watch the interior walls, floor and the ceiling below. If the seepage marks and damp patches that were there have gone, the insulation is working. Tell us if you notice anything unusual.
My concrete tank is old and has many cracks, can it still be insulated?
Many cracks do not prevent insulation, but they add to the preparation needed. Each crack is cleaned and filled before the insulation layer goes on, because applying insulation over an unprepared crack shortens its life. We ask about the tank's condition and approximate age when you call to gauge the preparation needed.
