How to use Nexpand
1. Measure the dimensions of the boulder or rock.
2. Drill holes to a depth that is at least 90% of the rock’s depth.
3. Space the drill holes approximately 250 mm to 300 mm apart.
4. Calculate the necessary amount of Nexpand for the job.
5. Ensure an ample supply of clean, cold water is available before mixing.
6. Combine one box of Nexpand powder with six litres of water.
7. Check the mixture’s consistency to ensure thorough blending.
8. Pour the prepared Nexpand mixture into the drilled holes, filling them up to
about 30 mm from the top.
9. Allow the mortar to set undisturbed for a minimum of 24 hours to achieve optimal results.
10. Avoid blocking holes with solid materials; use a waterproof sheet only in case of rain.
11. The reaction time varies depending on weather conditions, typically ranging from two to 24 hours.
