Waterproofing with FLEXIGUM
Scope | Features | Advantages | Technical specification
FLEXIGUM is two-component, bitumen-latex highly elastomeric
waterproofing product.
FLEXIGUM is cold sprayed product. It is applied on the surface with the help of airless spraying machine.
Scope of application
Bitumen-latex membrabe FLEXIGUM is designed for
waterproofing of the structural elements of underground and overground constructions in the industrial, civil and transport building and especially:
- Waterproofing and protection against corrosion of underground and ground building constructions, ferro-concrete and metal reservoirs, pipes
- Waterproofing of transport constructions, tunnels constructions and stations of underground, constructions of road and railway tunnels, constructions of retaining walls, pedestrian subways
- Waterproofing and protection from biogenic sulphate aggression of collectors of water disposal net

Features of the waterproofing material FLEXIGUM
- Stability – the uniformity of product application in the form of homogeneous membrane
- Flexibility – product, reinforced with latex, assumes unusual elastic properties, elongation more 1000%
- Workability – the product can be applied on the surface of any geometrical shape and configuration
- High efficiency – the brigade of 3 workers can spray the coating on the area up to 1200 m2, 4 mm thick layer during 8 hours
- Safety – non-toxic, cold sprayed application, environmentally friendly
FLEXIGUM is applied in mechanized way by means of airless spraying machine. The spraying process is carried out by means of submission of two components: bitumen-latex emulsion and coagulating agent through two circuits, which include flexible high pressure hoses system. The hoses are connected with two-nozzle sprayer, in which cone-like atomizers are installed. Components of a FLEXIGUM transform into cone-like jets at outflow, mix in the air and reaching the surface, form seamless membrane.

Advantages of the waterproofing material FLEXIGUM
- uneven surface does not affect the homogeneity of the membrane and its adhesive properties
- no scaffolding and stages are required for application on the surface up to 6 meters
- excellent adhesion to metal inserts located in concrete
