Nonwovens for dry cementitious grout packaging allowing controlled water absorption
Our high-quality nonwovens are used in the production of cementitious grout capsules for anchor bolting in mining. The capsules are filled with fast-setting cement to reinforce underground mine shafts. With excellent performance in converting and end-use processing, the nonwovens are ideal for manufacturers of anchor support systems. In addition, they provide mining and rock engineers, as well as contractors, with reliable solutions for demanding applications.
Key Features
- High dry strength for secure packaging and handling
- Low wet strength to facilitate grout penetration in anchor drill holes
- Good water permeability supporting cement activation and curing
- Reduces dry grout leakage due to the dense fleece structure
Key Benefits
- Saves packaging waste and material costs as the encasing is inserted into the anchor drill hole with the grout
- Single polymer (PES) raw material allows converting waste to be recycled
- Dry grout capsules can be transported to site, reducing transport and end use weight
- Controlled water/powder ratio
Reliable support for mining safety
Our high-performance nonwoven fabrics are designed specifically for use in cementitious grout capsules, a critical component in anchor bolting solutions for underground mining. These capsules, converted into durable sleeves by impulse welding or stitching, are filled with fast-setting cement to provide secure reinforcement in mine shafts and tunnels.
Thanks to their excellent convertibility and consistent performance during end-application processing, our nonwovens offer a dependable choice for manufacturers of anchor support systems. Engineered using point-sealed calendaring or thermo-bonding technology, our 100% polyester nonwoven materials deliver both strength and reliability in demanding underground environments.
Trusted by mining contractors and rock engineers worldwide, our nonwovens play a key role in enhancing the safety and stability of underground operations.
