This product has a high strength and is resistant to uptake of water. It’s compatible with use in cold conditions without need for additives.
Also, during the expansion, hold the post until it stands firm if there are cold or windy conditions prevail
Expansion will be achieved in approximately three (3) to five (5) minutes, but you have to allow approximately two (2) hours for the product to set completely before installing the fence or attaching gates, etc. to the post.
Immediately after mixing, cut one of the bag’s corners and pour mixed material into the hole before expansion starts. Empty the bag into the hole, pouring some of the material onto the post itself. Covering the section of post due to be below grade will help to improve adherence and protection to the base of the post. If necessary, the position of the post may be adjusted for up to ten (10) seconds after the material has been poured. Do not move the post after this time and support it until the material has firmed up. Expansion will be achieved in approximately three (3) to five (5) minutes, after which time there will be no need to brace or support the post (unless cold or windy conditions prevail, in which case hold the post until it stands firm). Allow approximately two (2) hours for the product to set completely before installing the fence or attaching gates, etc. to the post.
Mix thoroughly by shaking the bag for 20 seconds and by forcing material to travel in the bag, from one end to the other. Do not exceed mixing time as bag may rupture.
Note: Have scissors or a knife next to the hole ready to cut a corner of the bag after mixing is completed.
Dig or excavate (post drill) the hole to the proper depth (depends on post size, soil conditions and frost depths) and diameter (refer to the Examples in the Technical Data section). Make sure that the post is adequately positioned in the hole. The post should stand straight and level and be either braced or held before mixing the material.
Yes. If there is standing water in the hole, backfill partially with soil or gravel until water is no longer visible or pump the water out.
The service temperature is between -30 °C to +38 °C (-22 to 100 °F), but the material must be preconditioned to between +18 and +25 °C (65 and 77 °F) for at least 2 hours before mixing and use.
If the bag is above the recommended temperature before mixing, the product may expand too quickly.
