ACS Rapidseal VCD Grout has been specifically designed to enable the installation of a cost effective and permanent sealing system within underground coal mines – for the purpose of ventilation control and ground support.
The non toxic product is installed using a Langley grout placer pump or similar.
By adjusting the water content of water to powder ratios from 1:1 up to 2:1, Rapidseal VCD Grout will offer varying amounts of permeability and strength values. This characteristic enables the product to be used for a diverse range of applications.
- Plug seals in Ventilation Control
- Void filling in bulkheads
- Crack filling and soil stabilisation
- Cavity fill in goaf area
- Rib stabilisation
All areas to be treated with ACS Rapidseal VCD Grout should be clean and free from debris and loose material prior to application.
Use a Langley or similar placer pump. Ensure sufficient air and water is available to the job site (please read notes).
The air volume should be no less than 80psi and the water volume should be tested before commencing the job, to ensure sufficient flow for project application.
Note: Ensure continuous air supply pressure at the placer pump is no less than 80psi (550 KPa / 5.5 bar). Use of a 2” (Bull Hose) approved compressed air supply hose is recommended and do not reduce couplings or fittings.
The product relies on aggressive agitation at the pump to ensure adequate product mixing has occured .
The grout should be run through 60 metres minimum length x 25mm i.d. poly pipe.
All equipment should be washed with water at completion of job. Do not allow Rapidseal VCD Grout to sit in pump.
If stored in a cool, dry environment Rapidseal VCD Grout should keep for up to six months. The shelf life of the product may be reduced if subjected to high temperatures, high humidity or damp environments.
