Whether you need a water tank service near you for a tank that's been in use for years, or waterproofing septic tank work as part of a new house build, Ghar Plans treats both jobs as what they really are: sealing a concrete structure so it reliably holds whatever's inside it. Our water tank and septic tank waterproofing service covers both already-built and brand-new structures, so whichever stage your house is at, there's a version of this service built for it.
How Ghar Plans Delivers This Water Tank Service
The process depends on one thing: whether your water tank or septic tank already exists, or is being built as part of a new house. Here's exactly what happens in each case.
For an Already-Built Water Tank or Septic Tank (Old Houses). We start with a deep cleaning process, clearing out sludge, dirt, bacteria, and any harmful buildup that's collected over the tank's years of use — this matters both for hygiene (especially in a water tank storing drinking water) and because a waterproofing coat needs a clean surface to bond to properly. Once the tank is clean, our team carefully inspects it for cracks and leak points and seals them, so the waterproofing layer that follows isn't being applied over an active leak. Only once the surface is properly prepared do we apply a double coat of Sika Seal 105 — a second coat applied over the first restores a strong, continuous waterproof barrier across the whole tank, inside and out where accessible.
For a New House (Under Construction). Once the tank's concrete structure is ready, there's no old buildup to clean or existing damage to repair, so we move straight to waterproofing: a double coat of Sika Seal 105 applied directly to the bare concrete. Because Sika Seal 105 is a cementitious coating, it bonds mechanically and chemically into fresh concrete, which is exactly why it works best applied at this stage rather than added later. The result is a durable, reliable waterproof layer built into the tank from day one, so the water it holds stays clean, safe, and fresh for the long term.
Why Water Tanks and Septic Tanks Both Need Waterproofing
It's easy to assume a water tank and a septic tank need completely different treatment, since one holds something you drink and the other holds something you'd rather not think about. In practice, both are concrete (or masonry) structures doing the same basic job in reverse: containment. A water tank that develops a crack risks losing stored water and letting outside contamination in, which is a health concern if that water is for drinking or cooking. A septic tank that develops a crack risks the opposite — sewage and wastewater seeping out into the soil around your house, which is both unhygienic and, left long enough, a problem for your property itself. Sealing both with a double coat of Sika Seal 105 addresses that shared root cause directly.

Frequently Asked Questions
What does this water tank and septic tank waterproofing service include?
For an already-built tank, it's deep cleaning to remove sludge, dirt, and bacteria, followed by crack inspection and sealing, then a double coat of Sika Seal 105. For a new house, we apply the same double coat of Sika Seal 105 directly once the structure is ready.
Is the process different for an old house versus a new house?
Yes. An existing tank needs cleaning and crack repair first, since it's already been in use and may have sludge buildup or leak points. A new tank goes straight to waterproofing, since the concrete is freshly cast and hasn't had time to develop buildup or damage.
What does waterproofing septic tank actually involve?
Waterproofing septic tank structures means sealing the concrete shell so sewage and wastewater stay contained inside rather than seeping into the surrounding soil. Ghar Plans treats this with the same double-coat Sika Seal 105 application used on water tanks, after cleaning and crack sealing on an existing structure.
Is Sika Seal 105 safe for a water tank that stores drinking water?
Yes. Sika Seal 105 is non-toxic once fully cured, which is part of why it's suitable for water tanks used to store drinking water, alongside its use on septic tanks and other water-retaining structures.
How is watertank waterproofing different from septic tank waterproofing?
A water tank needs to keep clean water in and contamination out, while a septic tank needs to keep sewage and wastewater from leaking out into the soil. Ghar Plans addresses both with the same core waterproofing treatment, since in each case the underlying job is sealing a concrete structure so it reliably holds whatever's inside it.

Protect What Your Tanks Are Holding
A water tank or septic tank usually only gets noticed when something's already gone wrong — contaminated water, a foul leak into the garden, or a costly repair once the damage is done.
