Why is proper pool waterproofing important?

Leaks in a pool lead to water loss, increased operating costs, and in extreme cases can cause damage to the pool structure or adjacent building components. Professional waterproofing reliably prevents these risks.

Which products does BT innovation offer for pool waterproofing?

BT innovation recommends the use of InnoElast® Type 2 for sealing joints and cracks. The product is resistant to pressurized water, elastic, and can also be applied on damp substrates – ideal for the requirements in pool applications.

What are the advantages of InnoElast® Type 2 for pool waterproofing?

InnoElast® Type 2 is solvent-free, low-shrinkage, UV- and weather-resistant, and resistant to typical stresses in pool environments. It remains permanently elastic, can be applied without primer, and withstands pressurized water up to 0.48 bar or 4.8 m water column.

How can you detect if a pool is leaking?

A continuous water loss of more than 3–5% per week – without strong sunlight exposure or heavy pool use – indicates a leak. Visible puddles around the pool are another sign.

What conditions must be met for applying InnoElast® Type 2?

The substrate must be clean, free of grease and dust. It may be damp but not wet. For optimal results, application at higher temperatures with high humidity is recommended.

How is InnoElast® Type 2 applied correctly?

The sealant is applied into the prepared joint using a cartridge gun. A backing rod can be used if required. The material must then cure for 24 hours protected from moisture.

Sealing the pool with reliable solutions from B.T. innovation

Reliable sealing of the pool

Water loss – is one of the biggest concerns a pool owner can have. In the long run, a leak would result in higher costs, due to more water loss and increasing need for chemicals. If there are large leaks, the walls of the pool or the foundations of adjacent houses can be washed out, compromising structural integrity. Because the maintenance costs of a private pool are not exactly insignificant, repairing it is probably more cost-effective than building a new one. If puddles form around the swimming pool or it loses water, then there is a high probability that the pool has a leak. To make sealing easier for you, B.T. innovation provides you with a solution.

BT waterproofing products are ideal for this purpose:

To seal the pool permanently and reliably
Repair leaks from the fairing or filter system

Common causes of leaks

No matter whether your pool is made of vinyl, fiberglass, concrete, or shotcrete, a crack can develop anywhere. However, they do not necessarily have to occur on the cladding. There may also be leaks in the filter system. In principle, a leak in any type of pool can develop into a crack or hole and thus threaten the stability of the pool.

Cracks are possible in concrete pools due to temperature fluctuations or ground movement. In contrast, with tiled pools, draining the pool too quickly can cause tremendous water pressure to still exist behind the tiles, causing them to crack. In addition, black joints in tiled pools are more susceptible to cracking in warm water temperatures.

A special feature of pools is the water treatment used for disinfection. This not only acts on bacteria and microorganisms, but can also affect various materials and seals. To reduce these effects, it is advisable to protect the waterproofing systems accordingly. This is usually done by using weldable pool / swimming pool liners, suitable coatings or by installing tiles.

BT solutions for sealing your swimming pool

InnoElast® – Effective sealing of joints and cracks in the pool

To seal the pool comprehensively, we offer InnoElast® Type 2. With InnoElast® Type 2, you can have component joints and cracks permanently sealed against water under pressure of up to 4,8 m. Accordingly, the pool can be deep.

InnoElast® Type 2 has a high chemical resistance.
Under a cover by foil, coating or tile, it permanently seals the pool.
Quick repairs are also possible with the product.
If InnoElast® Type 2 is permanently exposed to chemically contaminated water, the joints or repair areas should be inspected regularly and maintained if necessary.

Advantages of InnoElast® Type 2

Solvent-free and low shrinkage
Applicable on damp substrates from -3°C
Weather and UV resistant, high resistance to chemicals
Permanently elastic
Up to 10% motion absorption
Applicable without primer
Pressure waterproof up to 0,48 bar

Instructions - Processing as a joint sealant

Step 1

Cut open the top of the tubular bag with scissors or pliers. In addition, clean the substrate (the joint).

Step 2

Insert the tubular bag into the spray gun and close the cap tightly.

Step 3

Fill the joint with InnoElast® type 1 or type 2. Optional: Use backfill cord.

Done

Protect the joint from moisture and leave it at least Cure for 24h.

You should pay attention to

If there is some manual dexterity and you want to seal your pool for the first time, here are a few more tips to help you get a positive result in the end.

Is there a leak?

In search of the hole should be sure in advance that the pool has a leak. It should be noted that water loss also depends on external factors such as air temperature and intensity of the sun. In addition, when jumping or romping in the pool, some water always spills out. Thus, the average demand for filling water of a pool per week is between 3% to 5%. For this reason, the water level should be monitored over a longer period of time.

The right condition

When applying the sealing material, the substrate must be free of dust, grease or oil. In addition, the substrate must be damp, but not wet, with a visible film. High air temperatures with a high absolute humidity are suitable for hardening the material more quickly. InnoElast® Type 2 is compatible with paints.
