DrucPestro is organic-mineral two components resin foam, characterized by low viscosity, excellent chemical stability, mechanical resistance, and good adhesion on rock stabilization, cavity filling, air and gas sealing, and consolidation of highly fractured strata. Once mixed in a volumetric ratio of 1:1 the component A and B produces an immediate foaming reaction.
APPLICATIONS:
- Filling up of caverns and voids.
- Improvement of subsoil conditions before starting the construction
- Micro piling in soil with a low bearing capacity
- Foundation of buildings in undermined areas
- Protection when crossing fault zones.
- Stabilization of loose material in the foreland of excavation.
- Securing of excavation during tunnel construction.
- Preventive improvement of mechanical properties of the rock mass in the line of the workings.
- Anchoring of soil and rocks.
- Strengthening and stabilization of overburden and etc.
FEATURES
- Low viscosity product allowing good penetration into the smallest fissures.
- Excellent adhesive strength.
- Yield to ground pressure accommodates subsequent ground movement.
- High mechanical resistance gives improved support of strata.
- Easy excavation possible with the cutting machine when used in coal faces.
- Easy excavation possible with the cutting and machining

RECOMMENDATION
The recommended operating temperature is from 15 °C to 30 °C. Therefore, it is recommended to store the product at a minimum temperature of 15°C before processing for at least 12 hours.
STORAGE, SHELF LIFE
The shelf life of the product is six months from the date of manufacture. The product should be stored in a dry place at temperatures between 15 °C and 25 °C. Improper storage will shorten the shelf life.
DISPOSAL
Small quantities of cured product residues can be disposed of as normal domestic waste. Disposal of uncured product components must be carried in accordance with the local regulations. Empty cans should be cleared of any liquid by punching a hole through the edge of the cover and turning them upside down until liquid does not flow out any longer.
