SikaGrout 510 CS High Flow 25kg

SikaGrout 510 CS High Flow is a high flow, non-shrink, high rapid strength cementitious grout.

Substrate Preparation:

The substrate should be prepared by suitable mechanical preparation techniques such as high pressure water jetting, breakers, blastcleaning, scabblers, etc. The concrete substrates should be pre-soaked with clean water continuously for 2 to 6 hours to ensure a saturated surface dry (SSD) condition throughout the operation. Immediately before pouring the grout, remove all excess or standing water from within any formwork, cavities or pockets.

Shutter / Formwork:

All formwork should be of adequate strength, treated with release agent and sealed to prevent leakage. Sealing can be achieved by using Sikaflex -11FC+ sealant beneath or around formwork and between joints. Ensure formwork includes outlets for extraction of the pre-soaking water. A header box / hopper should be constructed on one side of the formwork so that a grout head of 150 – 200 mm can be maintained during the grouting operation.

Measure the appropriate amount of clean, potable water (if necessary, warm water to achieve a temperature between +15 and +20^oC) to achieve the desired grout consistency given in the aforementioned table and pour into a clean, suitable mixing vessel for each complete unit of SikaGrout -510 CS High Flow to be used. Flexible mixing vessels (e.g. ‘gorilla tubs’) are unsuitable – rigid vessels shall be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque, slow speed (i.e. 200 to 500 rpm) drill with an appropriate grout stirrer, or a grout mixer set on slow speed for small mixes. The use of a drill and paddle (in most circumstances) is only suitable for mixing one bag at a time. For larger mixes, use forced action type mixers (NOT concrete tumble mixers which do NOT apply sufficient shear, NOR high speed or colloidal mixers, as these may cause thixotropy, leading to loss of flow). This Product is NOT suitable for mixing by hand. If using a drill and paddle, keep the mixing head in the material – refrain from lifting in and out, as this will introduce air. It is of utmost importance that the Product is mixed thoroughly to the desired consistency (i.e. for at least 3 minutes). Fresh grout (particularly at the highest water level) should be allowed to stand until the air entrapped by mixing has been released before application (typically 1 to 2 minutes).
