ROCSIL ® FOAM CAVITY FILLING SYSTEM
Description

ROCSIL® FOAM is a two component product, intended for cavity filling, air and gas sealing and stabilisation of highly fractured strata.ROCSIL® FOAM is applied using a metering pump and a mixing gun.

The mixing of resin and catalyst, in a volume ratio of 4 to 1, produces an immediate foaming reaction, followed by a rapid expansion of the product to as much as 35 times its original volume. After expansion, ROCSIL® FOAM hardens in appoximately 5 minutes.

Its rapid application, high expansion rate, good compressive resistance and excellent antistatic properties offer an economical, quick and safe cavity filling solution.

By virtue of its fire resistance classification, ROCSIL® FOAM is also suitable for sealing off underground heatings and mine fires.


Advantages
a) Extremely fast, safe cavity filling operation-will fill up to 75m3/hour
b) High expansion rate means smaller quantities of product and materials to be delivered to underground location-70% less than foaming cement
c) Minimal formwork required due to high expansion, fast setting product
d) Excellent compressive strength
e) Expands in situ providing positive support to the cavity
f) Minimal leaks due to high foaming and fast setting time
g) Will not block or seize AFC
h) The product will not burn or propagate flame
i) Can also be used for injection where there are large voids in strata
j) Compressed air driven pump-low air volume requirement

Applications
a) Cavity filling on longwall faces
b) Cavity filling in gate roads
c) Rapid sealing of mine roadways
d) Sealing of underground heating and mine fires

IMPROVE SAFETY AND SAVE DAYS OF LOST PRODUCTION !!!!

Rocsil Foam is a LOBA (Arnsberg) approved product. Rocsil Foam has eliminated foaming cements for cavity filling in Australia coal mining.
