Packaging 25 kg 5 l, 20 l

Advantages

For filling cavities and large cracks in concrete and masonry, a suspension based on shrinkage-compensating plasticized cement is used.

For inhibiting the rise of capillary moisture in brickwork, an injection mortar on a silicate-organosilicon base is used.

Technical features of injection materials

Structural reinforcement = R Long-term elastic waterproofing = L

Temporary waterproofing = T The most suitable application option is

determined according to the rheological properties of the injection system and

damaged concrete structures

T L R R L L L L L R

Withstands dynamic loads after hardening

Non-elastic injection systems may cause subsequent cracking in other places

Long-term waterproofing Long-term efficiency and reliable protection against subsoil waters

Structural reinforcement Injection system strength

is suitable for repair works with weaker concrete and lime mortar

Penetrates fine cracks (e.g., > 0.3 mm) Low viscosity of the injection material

determines the degree of penetration into cracks and reduces the injection pressure

Temporary waterproofing Suitable for short-term interruption of

pressure leaks

Reacts only in contact with water Reaction initiates only when necessary

Injected as a single-component system Injection systems with long

working life (> 20 min) can be injected with a single-component pump

Injected as a two-component system Injection systems with short working life (< 20 min) can only be injected with a

two-component pump

Gravity feeding Possibility of mortar pouring without

additional pressure, by gravity (manually) For example, pouring into cracks on

a reinforced concrete floor slab from the floor surface

Drinking water quality Injection material is environmentally safe

The process can be accelerated Faster reaction speed reduces the waiting

time in the course of work performance (especially at low temperatures) and

prevents resin from washout
