TECHNOLOGY APPLICATIONS FOR HYDRO ISOLATION AND REPAIR OF UNDERGROUND FACILITIES

INJECTION GEL

www.eurastechnology.com

WHAT ISINJECTION GEL?

An injectable gel is a flexible mass of mineral origin, for both dry and wet surfaces

solvent-free, durable soft-flexible. It is resistant to weather influences and UV radiation. It is resistant to frost and temperatures up to +100 C.

It has a binding capacity of water, and squeezes out the remaining water from its environment.

As a gel, the substance is water resis-tant and has high resistance to diffu-sion, to salt water and cold tempera-tures.

It is not corrosive and is not affected by operations in bituminous surfaces.

An injectable gel is a particularly convenient and irreplaceable in the prevention of water penetration into the interior of underground (basement) rooms, or for recovery of inaccessible parts of underground or partially underground facilities, tunnels, hydroelectric power plants, swimming pools, fountains, and the like.

The material is suitable for sealing surfaces and joints in materials such as concrete, brick, glass, ceramic, aluminum, iron and all kinds of steel, copper and various synthetic materials.

WHERE TO APPLYINJECTION GEL?

Repair, in most cases, is achieved by drilling injection holes in the damaged area of a structure and placing injection packs (operating and control) into them. The number and arrangement is determined separately for each case and depends on the quantity of water inflow, dimensions of the elements that are drilled and quality of the material from which the element is made of.

Through operating packs working under high pressure (50-200 bars) the right amount of gel is injected in the direction from which water under pressure enters into the interior. Injection is performed until on control packs, instead of water, gel appears. This ensures that water is permanently removed from an affected zone, and gel takes its place thus preventing remaining potential impacts of groundwater under pressure to occur.

The amount of gel that is injected, in principle, corresponds to the volume of water squeezed out. The mass remains permanently in the gel state, blocks the passage of water, what finally results in a successful elimination of water from the damaged zone and therefore the successful remedial and preventive actions to possible further water penetration.

Euras gel type -20

A new type of gel injection, offering all the usual features, manages to maintain resistance to

0freezing to -20 C. Applications include the areas exposed to severe frosts, near the surface (the tunnel's entrance, flat roofs, ...etc).

Euras injection mortar

We have developed a new type mortar injection (with or without use of cement) that is used for contact and injecting underground structures, which, unlike other materials of the group dur-ing injection, remains homogeneous , without changing water-cement ratio and without

3decomposition, specific gravity of 2.10 t/m .

This procedure enables mortar to achieve, except for contact constructive functions, also a waterproofing function from the first moment of its placing.

Euras gel type 10+

As a result of testing and development of new technology for gel injection , there is a remarkable result in anti-corrosive properties of the material, so that it is increased above pH 10 (passivation of reinforcement steel). Thus a requirement by Deutsche Bahn AG is satisfied concerning the conditions of application of gels in the repair of reinforced concrete structures (tunnel). The system is in the process of certification at the Institute in Germany, what will open a possibility for applications in a seamless system of expansion joints rehabilitation in tunnels . According to our knowledge it is currently the only system that meets the latest technical requirements.
