Sika Grout Application Guidelines

SikaGrout-100 is a ready mixed high power grout comprising an admixture that will compensates for the shrinkage typically correlated together with Portland cement based grout. Your exceptional fluidity indicates it can end up being used traditional pour and strain grout pumping deliver methods.


Correct and thorough surface preparation can be required to accomplish the actual substantial performance qualities involving SikaGrout-100. Most surfaces must be clean, sound and free of dust, oils, grease or any other surface contaminants like concrete curing membranes etc. Pertaining To maximum bond, surfaces roughened or even ought being abraded, preferably through mechanical means which includes needle gun, grit blasting, abrasive grinding etc. Pockets which are to become filled along with bolt holes needs to always be able to be without any dirt and also debris by air blasting.


All prepared surfaces must be saturated just prior to grouting, providing a saturated surface dry substrate state. Remove coming from surfaces and also bolt holes prior to adding grout. Your formwork should be leak-proof in order to enable totally free fluid SikaGrout-100. This specific may allow gravity flow to completely fill the actual void being grouted. Formwork ought being coated to permit straightforward elimination of forms.


SikaGrout one hundred has for you to be blended employing a mechanical grout mixer or a drum mixer which is suitable. Your grout mixer will definitely minimize the options involving this mixture turning out to be able to be aerated as well as lumpy. smaller amounts wants to become blended within clean drum using coil drill as well as an electric drill as well as coil mixer at a speed of approximately 500 rpm. Don't mix by hand.


It is vital in which suitable putting will be delivered without hold-ups. adequate labour and also equipment ought to be able to be existing for you to ensure continuous placement.


Gravitation Flow Delivery


Combined grout ought in order to be poured 1 side of the void so as in order to stay away from air entrapment. Grout is poured more than short areas to ensure this. Utilize the proper header box, keeping your grout head whatsoever times for you to ensure continuous flow.


To ease grout compaction along with leading plate contact, use rodding, tamping or even flexible strapping in short strokes and keep a sufficient head of grout. While this could cause segregation, don't vibrate. any adjoining machines or even equipment causing shaking should be shut down until first environment (5 to become able to 6 hours)


Pumping Grout


When grout pumping Sika Grout, ensure the actual pump would work for the grout consistency and also for your length as well as height it's to be pumped. a positive displacement pump is actually advocated. by pumping to the farthest corner, filling the actual room slowly region grout. Ensure that air isn't entrapped. The recommended thickness of SikaGrout-100 in one pour will be 20mm to always be able to 50mm. minimum thickness is actually 10mm. Maximum thickness in a grout pumping pass is actually 100mm. Virtually Any grout pour in which exceeds this ought to be done within stages, or even have stone aggregate put into slow up the exothermic heat entrapment.
