- Carrying out a proactive inspection of sealing systems on site and recommendations for joint maintenance.
- Sealing and insulation consulting according to the client's needs while taking into account the budget and the needs of the project.
Characterization of needs and consulting in the selection of suppliers (in collaboration with a client) in areas such as:
  • Sealing systems
  • Bitumen sheets
  • Polyurethane sealing systems
  • Cementitious sealing systems
  • Injection sealing systems

Sealing systems

Bituminous sheets made of bituminous compounds reinforced with glass fabric are suitable for sealing

Roofs, balconies, floors of underground buildings, ceilings of parking lots.

Advantages: relative resistance to mechanical damage.

Disadvantages: when performing a sealing system, the inability to achieve complete adhesion of the sealing system to the infrastructure, which creates a complete collapse of the sealing system in case of failure.

Bituminous sealing system, bituminous sheets

One-component bituminous emulsions are made by spraying or applying and are suitable for sealing rooms

Wet, small balconies, planters, walls of underground buildings.

The waterproofing system is water-based and suitable for those building a green building.


Advantages: full adhesion to the infrastructure and in case of failure the failure is spot on and easy to identify and repair elasticity of the sealing system up to 1300%!


Disadvantages: sensitive to mechanical damage and the sealing system must be protected according to the manufacturer's instructions.

There are those who will crown polyurea the next ball of the world of coatings thanks to the combination of a number of physical properties that make it unique. Polyurea is an elastomer that is applied in a "hot" spray and what makes it especially unique compared to conventional coatings is that on the one hand it has all the good properties of the alternative coating, epoxy: resistance to Abrasion and chemical resistance, but on the other hand, here is the virtue of the polyurea: the material is flexible and does not crack like the epoxy (epoxy has 6-8 percent elongation compared to 200-1000 percent for polyurea). Another and important advantage is that the polyurea dries in a few seconds, which allows both a quick return to service of the facility and the construction of thicknesses on vertical surfaces for sealing or protection purposes.  To sum up, since on the one hand, polyurea is an elastomer with bridging capabilities over a crack and has extremely high intrinsic physical properties, it is used as a coating for protection against erosion, chemical protection, corrosive protection, and sealants, often at an unconventional and industrial level._22200000-0000-0000-0000-0000000000222_


Examples of well-known applications where polyurea is used as the preferred coating:

  • Sealing of water reservoirs including water reservoirs used to store drinking water with the approval of the Standards Institute for contact with drinking water

  • Sealing sewage ponds and storm drains,

  • Sealing from treasures

  • Sealing sewers

  • Sealing surface parking lots when the polyurea is used as a sealing and finishing system at the same time

  • Protection against corrosion in the most difficult conditions


Disadvantages: The main disadvantage of polyurea is precisely on the planning, implementation and financial side, since it is not forgiving of "shortcuts" and therefore proper planning and proper execution (that is, under supervision) is critical in the success of polyurea implementation.

Polyurea elastomer of the next generation for industrial systems

A two-component water-based bituminous emulsion, suitable for sealing underground structures

Roofs of parking lots, bridges, roads, deep elevator shafts (minus 160 meters), tunnels and more.

The sealing is carried out by spraying up to a thickness of 6-8 mm. The sealing system is water-based and suitable

for green construction.


Advantages: full adhesion to the infrastructure and a large sealing membrane thickness (6-8 mm) elasticity of the sealing system up to 1600%!


Disadvantages: sensitivity to mechanical damage and the sealing system must be protected according to the manufacturer's instructions.

There are several polyurethane-based sealing systems, mostly imported from abroad and not always suitable

For the Mediterranean climate, one must pay attention to the manufacturer's instructions abroad since they are not always followed correctly

in Israel

In cases of using a polyurethane sealing system   in places exposed to the sun, make sure

The system's resistance to solar radiation (the aliphatic systems family).

These sealing systems are suitable for sealing roofs, balconies, wet rooms, the sealing is done

by spraying or applying.


Advantages: full adhesion to the infrastructure, high resistance to wear.

Disadvantages: The sealing system contains dangerous solvents and should be used with caution.

Polyurethane sealing systems

Cement-based sealing systems are suitable for sealing walls under stone cladding,

Room walls

wet (showers) water reservoirs, foundation beams, and more.

In special cases, special cement sealing systems must be used, for example swimming pools.


Advantages: withstands negative water pressure, a wide variety of different products can be applied to it, including flooring.

Disadvantages: not flexible enough and prone to cracking.

Cementitious sealing systems
