CONFALT COVER

CONFALT is a seamless wearing coat allowing to combine the sufficient strength of Confalt cement mortar and the mobility of porous asphalt. This is a durable, semi-rigid topcoat. This result is achieved by laying porous asphalt with 22-28% voids. Subsequently, the surface is covered with CONFALT cement mortar, which penetrates and fills in the voids.

The CONFALT cement mortar has a short curing time and its firmness is achieved rather quickly, therefore, commercial flooring, roads and other transport areas can be renewed and started to use again within 12-36 hours after work, depending on the air temperature and the thickness of the layer.

The CONFALT cement mortar has compensating shrinkage properties to reduce the number of visible cracks on the surface and to prevent cracks because of breaking in the structure.

PROPERTIES

  • excellent combination of firmness and mobility
  • seamless coating for indoor and outdoor surfaces
  • extended service life for roads and outdoor areas
  • temperature resistance from + -50℃ to +90℃
  • perfect for heavy duty static cargo areas
  • resistant to icing/thaw and ice melting salts
  • extra dense microstructure
  • resistance to chemicals
  • highly resistant to wear
  • very long service life
  • does not emit poisonous dust
  • quick installation and hardening

USAGE

Confalt is particularly suitable for areas where the surface layer is affected by high static loads and mechanical loads of trailers, lifts, etc. The Confalt surface coat is suitable for both indoor and outdoor uses. Confalt coatings are extremely resistant to wear due to the presence of granite on their surface.

There are several ways to obtain various surface structures:

  • The texture can be formed on the surface as terrazzo floors ("terazzofloor") and covered with varnish.

  • The texture can be formed on the surface by layer under linoleum, vinyl, epoxy covers, etc.

  • The finely corrugated surface can be coated with epoxy or PU for easy maintenance and increased resistance to chemicals.

MIXING-INSTALLING

Porous asphalt concrete is mixed in a hot mixing asphalt plant used for traditional asphalt. It is poured over on CBM, asphalt or concrete using asphalt or concrete paver. After pouring a layer of porous asphalt, it is compacted with a static roll to obtain evenly smooth surface. Once the porous asphalt is cooled, Confalt cement is mixed with a silo mixing pump and poured onto porous asphalt using rubber coated trowels. Finally, the surface is level with a rubber coated trowel to form a solid structure.

SURFACES

The standard CONFALT surface with a smooth, rough texture is obtained by brushing it with a rubber coated trowel. The same applies for attractive textured, painted or coloured surfaces. Confalt is ideal as a seamless underlay for linoleum, tiles and carpeting in supermarkets and big stores.

Typical CONFALT applications:

  • storage premises
  • commercial flooring
  • warehouses with high racks
  • shopping centres
  • underlays for linoleum, epoxy or carpet
  • terminals for storage of containers
  • airport aprons and take-off/runways
  • ice melting and washing areas
  • bus stops/stations
  • marina territories
  • parking
  • repair of asphalt and concrete floors
  • The Confalt wearing layer is usually laid at a thickness of 3-7 cm on CBM, asphalt or concrete.

URAREMIX METHOD

Uraremix is road pavement renewal method by mixing. It enables to perform road pavement repairs cost effectively and quickly.

Uraremix (Finnish "ura" – rut) is recommended when it comes to removing road ruts, seams, pits, crack nets or elongated cracks.

Uraremix allows to fully utilise the old asphalt mass. The affected coating is additionally covered with the required amount of asphalt concrete mixture and, if necessary, an additional binding agent.

KEY TECHNICAL INDICATORS

The width of the repair work area with Uraremix is ​​1 ÷ 1.2 m thus all repair work can be performed only in the ruts or other damaged areas. Work capacity: 2–3 km of restored ruts per shift. From the start of work to fully functional coverage: 3 hours.

APPLICATION OF THE METHOD

When using the Uraremix method, the surface of the affected area is heated with infrared rays. The old heated asphalt mass is milled to the required depth (maximum 4.0 cm).

The new mass of asphalt concrete and the binding agent, if used, is mixed with the old mass. The blended mass is laid with a paver and levelled with a roller thus providing a new wear protection layer.

ADVANTAGES OF THE METHOD

The method is cost-effective in terms of price/quality ratio, since only the most worn out part of the pavement is repaired, the money is used purposefully, and only where appropriate.

Since small machines are used for road repairs, there is no danger to other road users. The Uraremix method does not preclude the possibility of repairs in the same place.

Uraremix can be used both out of town and in settlements – road intersections, wells and utility elements do not interfere with the use of this technology.

Uraremix allows to cycle 100 percent of the current material making this approach eco-friendly.

No waste is accumulated during construction and requires no transport and storage.
