Swelling waterproofing – innovative material for absolute protection of structures from moisture

In both construction and maintenance, protecting structures from moisture is crucial. While conventional waterproofing techniques have had their usefulness, new developments in the field have led to the development of expanding waterproofing materials, which provide unparalleled protection. These cutting-edge materials are made to offer a strong barrier against water intrusion, guaranteeing the longevity and resilience of infrastructure and buildings.

When swelling waterproofing comes into contact with water, it expands to form a tight seal that shuts off all possible entry points. Because of this special quality, it can effectively stop water damage even in difficult situations. Its versatility in caulking gaps and fissures gives it a major edge over traditional waterproofing techniques.

Swelling waterproofing materials can be applied to a variety of situations due to their adaptability. In a variety of construction settings, these materials offer dependable moisture protection for everything from water reservoirs and tunnels to basements and foundations. They are a desirable option for both new projects and repair work because of their durability and ease of application.

Buildings with swelling waterproofing have improved structural integrity and eventually lower maintenance costs. These materials help create safer and healthier living and working environments by preventing water-related problems like corrosion, mold growth, and structural weakening. Using this cutting-edge technology will help us move toward more sustainable and resilient building techniques.

Swelling waterproofing – what is it?

Some kinds of waterproofing work on the basis that when they come into contact with moisture, they expand to fill any available space and further stop water from penetrating. This characteristic served as the inspiration for the materials’ name, swelling waterproofing. Other terms for an entire class of seals with comparable characteristics are swelling profile and hydraulic laying.

Generally speaking, swelling waterproofing is made of water-soluble resins, modified rubber, or synthetic rubber equivalents. As soon as the chemical reaction commences, the material begins. All pores and cracks are eliminated as the swollen material merely moves the water.

Crucial! Any structure for which moisture contact is undesirable is protected with waterproofing, which has the potential to increase volume.

The main varieties

There are many kinds of swelling waterproofing available; most of them show roughly equal efficiency, but differ in terms of release mechanisms, styling techniques, and intended use.


Profiled components called hydroshponki are used to waterproof joints in concrete buildings. Plastic polymers that have specific properties, such as thermoplast and polyvinyl chloride, are what make up their composition. Among them are:

  • high resistance to moisture, weak solutions of acids and alkalis, salts;
  • biological inertia;
  • significant strength;
  • preservation of plasticity at temperatures from -30 to +50 degrees;
  • environmental friendliness;
  • Simplicity of installation.

Maximum sealing of joints and seams is provided during the installation of the hydraulic spoke. Waterproofing comes in a variety of shapes and sizes (angular, P-shaped, clamping, etc. D.), so you can choose it to suit your needs.

Note: This material is perfect for securing technological and compensatory seams in monolithic construction; it can also be used for other concrete-related tasks, such as setting up treatment plants, swimming pools, water supplies, and underground utilities at high groundwater levels.

The hydraulic lines are separated into the following categories based on their intended use:

  • formwork – put when pouring a monolithic structure directly into the working formwork, allow you to create mobile deformation seams;
  • internal ones – are used in the course of new construction, repair, to restore seam tightness;
  • Protective – are used for isolation and devices of technological seams, attached to the outside, from where the water pressure acts;
  • repair – are needed to close up seams in existing structures.

Bentonite cord

This type of expanding waterproofing is composed of unique raw materials, such as a naturally occurring mineral that resembles sodium clay and contains polymer and rubber additives (bentonite). When exposed to moisture, it expands by 200–500%, gaining significant volume, and eventually taking on the consistency of gel. Owing to its characteristics, the cord finds extensive application in the production of waterproofing coatings as well as in the processing of joints and seams, both vertical and horizontal.

The principal attributes of the cord are:

  • absolute filling of the cavity in which it is placed;
  • withstanding large hydrostatic pressure;
  • Gap strength – from 0.4 MPa and above;
  • resistance to the pressure of a water column 30-70 m, work with a variable or permanent hydraulic load;
  • unlimited number of freezing and defrosting cycles;
  • excellent tolerance of temperature changes, maintaining flexibility even at -40 …+100 degrees;
  • resistance to the action of aggressive environments (acidic, high -growing);
  • Inappropriateness of decay, decomposition;
  • service life – from 50 years;
  • the possibility of use even in food production for sealing containers, pipes.

Bentonite cords come in three different configurations: a square section measuring 30*30-50*50 mm, a rectangular cross section measuring 10-60*20-100 mm, and a round section measuring 10-120 mm in diameter.

Crucial! Bentonite ropes are perfect for isolating water tanks, swimming pools, and other reinforced concrete structures. They can also be used on curved sections.

Waterproofing tape

This type of material is made using fabric and synthetic rubber combined with unique polymer additives. It can withstand 100% stretching and is easily mounted and fixed on any surface. It also maintains its flexibility and elastic properties over a wide temperature range of -20 to +70 degrees.

Because waterproofing ribbons made of various materials have a high level of adhesion, they are used for everything from zero cycle (deformation seams) to the repair and removal of window and door block cracks. Both internal and external use tapes are available for purchase.

A significant development in the defense against moisture damage to structures is swelling waterproofing. This novel substance combines with water to create an impenetrable, tight seal that keeps buildings safe and dry. It is incredibly effective at sealing even the smallest leaks and cracks because of its capacity to swell when it comes into contact with water.

Superior longevity and dependability are provided by swelling waterproofing when compared to conventional methods. In addition to offering instant protection, it also adjusts with time, continuing to be effective even when structures move or settle. Because of its versatility, it’s a recommended option for both new builds and renovations.

Furthermore, swelling waterproofing is easy to install, which reduces labor costs and installation time. Because of its effectiveness and simplicity of use, it can be applied to a wide range of projects, including big commercial buildings and residential homes. Builders can make sure that structures are better suited to handle issues related to moisture by incorporating this material into their construction processes.

Swelling waterproofing is a potent moisture-resistance technique overall. Its creative design and useful features make it a crucial part of contemporary building, providing any structure it guards with long-lasting durability and peace of mind.

Swelling waterproofing is an innovative method that provides different types of structures with unmatched moisture resistance. When this novel material comes into contact with water, it expands and forms a tight seal that effectively stops leaks and water damage. It guarantees enduring defense for tunnels, basements, foundations, and other important areas and is very easy to apply. You can protect your property from moisture’s harmful effects and ensure structural integrity and longevity by using swelling waterproofing.
