Preparation

Firstly, please measure the temperature and make sure that the job-site, demolition agent, rock, container and temperature are in compliance with requirements. If traditional type is to be used, please select correct specification. If SPLIT POWER to be used, please add inhibitor as instructed.
Demolition Design

  • Make sure that there is plenty of clean and cold water and towels on the job.
  • Make sure the temperature of the holes meet the requirement before loading.
  • Make sure the holes are clean and no water and residues are left in the holes, use high-pressure air to clean out so the loading depth is 100% of the pre-drilled holes.

Demolition Design

For VERTICAL and downward situations, it is necessary to identify that there is at least one free face there. The diameter of holes is crucial to the cracking results. Too small holes are not in favour of good performance of the agent, while too big holes may cause blow out. Holes 30-40mm diameter is recommended. If the cracked objects are isolated, the depth of drilled holes is equal to 80-90% of the objects thickness. If used in Marble and Granite quarrying and mining, the depth of drilled holes should be equal to 110% of the objects thickness. To very long holes, tamp the mortar section by section. It is not necessary to put on any restrictive cap, Just leave as it is and wait until crack initiates. For horizontal and slant holes, insert a slightly smaller plastic pipe into the hole, and then fill the mortar into the pipe slowly, withdrawing the pipe from hole simultaneously. Quickly block the hole with a cap after feeding. All operation including mixing and pouring should be finished as soon as possible,
it must be completed within 10 minutes.

Mixing

SPLIT POWER is a powder that must be thoroughly mixed in a ratio of 30% of the overall weight with clean and cold water before use.
Pour 1.5-1.7 litres (3-3.5 pint) of clean cold water into a container, then gradually add one bag (5kg) of SPLIT POWER powder into the water and stir until obtaining a smooth, lump-free slurry.

Loading

For vertical holes, pour SPLIT POWER mixed with water into hole directly. For horizontal and slant holes, insert a slightly smaller plastic pipe into the hole, and then fill the expansive mortar into the pipe slowly, withdrawing the pipe from the hole simultaneously. Quickly block the hole with a cap after feeding.

Cautions

  • Make sure that there is plenty of clean and cold water and towels on the job.
  • Make sure the temperature of the holes meet the requirement before loading.
  • Make sure the holes are clean and no water and residues are left in the holes, use high-pressure air to clean out so the loading depth is 100% of the pre-drilled holes.
  • There should be a sufficient number of workers on the job to take synchronized steps when mixing, stirring and filling so that the expansive mortar will be poured into the holes within 10 minutes after mixing is completed, this will guarantee that the maximum expansive stress of all holes occurs at the same time.
  • If the mortar start to get warm and bubble before finish loading, don’t fill it in the holes, it must be discarded, it is forbidden to fill into the holes and it could cause the mortar to blow out of the holes.

Safety Precautions

The following warning has to be observed closely when dealing with SPLIT POWER.

  • Safety goggles and rubber gloves and MUST be worn at all times while preparing, mixing and loading SPLIT POWER.
  • Keep your face away from the loaded holes. Cover the holes with a tarp after loading. Stay away from loaded holes at least 3 hours after loading.
  • In case of contact with the products in your eyes or on exposed skin, either in dry or wet form, wash the area immediately with large amounts of cold and clean water without rubbing. Consult doctor quickly.
