5. FILLING GROUT VOID
5.1 In case that the base skid has a grouting void, the following steps shall be done:
i. Check for voids by tapping along the top deck of the mounting plate.
ii. Mark the void areas to allow the proper identification when rectifying. A solid sound indicates a good grout area while a drum like hollow sound indicates a grout void and requires filling of grout.
iii. Make the holes by drilling for filling. Diameter of the holes is about 20mm – 30mm. One (1) hole is for the pouring while the other holes will be served as a vent to avoid air trapped during the placement of grout.
iv. Ensure that the mixing of epoxy grout is complied as per manufacturer procedure.
– Void Thickness
– Up to 10mm: Only Base and Hardener can be used.
– More than 10mm: Base and Hardener with three bags Aggregate only(not four bags) can be used. Mix base and hardener then add three bags aggregate (one by one)
v. The third party laboratory to do the sampling and testing of cube samples for grout.
vi. Pour the grout into the hole steadily until it emerges on all vent holes.
vii. Clean all the areas with excess grout before it sets.
viii. Re-check for voids to make sure the filling.
6. SAFETY INSTRUCTIONS AND PRECAUTIONS
6.1 Make sure that all necessary work permits are issued.
