Cementitous Grouts - SikaGrout®-328
High performance, precision, grout with extended working time
SikaGrout®-328 is a non-shrink, non-metallic, cementitious precision grout powered by ViscoCrete technology. This grout provides extended working time and exceptional physical performance at fluid consistency. A structural, precision grout, SikaGrout®-328 can be placed from fluid to dry pack.
- Multiple fluidity with one material
- Reaches 10,000 psi in dry pack consistency
- Outstanding performance in fluid state
- Extended working time
- Excellent fluidity - sufficient time for placement
- Contains premium quality quartz aggregate
- Hardens free of segregation
- Non-metallic, will not stain or rust
- Shows positive expansion
Usage
- Where exceptional one day and ultimate compressive strengths are required.
- Applications requiring a pumpable grout.
- Non-shrink grouting of machinery and equipment, base plates sole plates, precast panels, beams, columns and curtain walls.
- Applications where a non-shrink grout is needed for maximum effective bearing area to transfer optimum load.
- For underwater application in conjunction with Sikament® 100 SC. Consult Technical Service for dosage information. Independent test data is available however on site testing is recommended to confirm performance under actual field conditions.
- For grouting rebar, bolts, dowels and pins, etc.

Application Steps
MIXING- Pour the water in the recommended proportion into a suitable mixing container.
- DO NOT OVER WATER!
- Ambient and material temperature should be as close as possible to 70 °F. If higher, use cold water; if colder, use warm water.
- While mixing slowly, add the powder to the water.
- Mix thoroughly for at least 5 minutes with low speed (400-600 rpm) using a Sika mixing paddle or a jiffy paddle to avoid entraining too much air and until homogenous with no lumps.
EXTENSION WITH AGGREGATES
- For deeper applications (plastic and flowable consistancy only), 25 lbs. of 3/8" (9.5 mm) coarse aggregate can be added.
- The aggregate must be non-reactive (reference ASTM C-1260, C-227 and C-289), clean, well graded, saturated surface dry, have low absorption and high density, and comply with ASTM C-33 size number 8 per Table 2.
- Variances in aggregate may result in different strengths.
- Add pea gravel after the water and SikaGrout®-328.
APPLICATION- Within 60 minutes after mixing, place grout into forms in normal manner to avoid air entrapment.
- Vibrate, pump, or ram grout as necessary to achieve flow or compaction.
- SikaGrout®-328 must be confined leaving minimum exposed surface.
- After grout has achieved final set, remove forms, trim or shape exposed grout shoulders to designed profile.
- SikaGrout®-328 is an excellent grout for pumping, even at high flow. For pump recommendations, contact Technical Service.
CURING TREATMENT- Wet cure for a minimum of 3 days or apply a curing compound which complies with ASTM C-309 on exposed surfaces.
