Nex-Pand is a patented, noiseless and non-explosive solution that is perfect for sensitive projects where blasting is prohibited. This simple, easy to use product allows the owner/contractor to do his own rock and concrete breaking without the risks associated with more regulated and controlled rock breaking products.
To determine how much Nex-Pand you’ll need, please apply the following rules;
32mm drill hole – 1.1kgs per running meter
32mm drill hole – 1.3kgs per running meter
34mm drill hole – 1.5kgs per running meter

Do both of these at the same time:
- You can drill the holes oversize, for example instead of drilling them the 36mm diameter you can drill them 45mm diameter keeping the holes 300mm apart.
- You can keep the 36mm diameter holes and reduce your hole spacing to 24cm apart.
Yes you can, just space your holes at 15 – 20cm apart.
- Electric drills
- Pneumatic drills
- Hydraulic drills
- Yes you can, as long as it is covered after you have poured it. This will prevent the rain water diluting the mixture.
- If the holes are full of water already, you have to blow the water out before pouring, then cover with plastic to prevent water from diluting the mixture.
