PRODUCT DESCRIPTION
TERRACO TERRAROC NS 100 is a general purpose non-shrink cementitious grout designed for narrow void grouting, flow screeds and anchoring of a wide variety of fixings. Its non-shrink and free flowing properties are ideally suited for ramming, pumping or pouring. The simple addition of a required amount of water determinesits wide range of applications. Due to its early strength development it allows for quick return to service of grouted areas.
PROPERTIES & BENEFITS

- Early strength development.
- Non-shrink.
- Can be poured or pumped.
- High compressive strength.
- Chloride free.
- Extensive workability.
AREAS OF USE
TERRACO TERRAROC NS 100 is designed for use in the following areas:
- Narrowing void grouting (flowable state).
- Grouting of anchor bolts and manholes.
- Installation of fencing or boundary posts.
- Where grouting of between 10 to 100mm is required (refer to bulking procedure).
- Concrete floor repairs and screeds.
- Machine and pump plinths.
SURFACE PREPARATION
Ensure that all dust, dirt and foreign matter are brushed and scraped away. Also ensure the surfaces are free from salts, oil, grease and ridges, and protect all adjacent surfaces not to be covered.This must be removed either chemically or mechanically. The surface where TERRACO TERRAROC NS 100 is to be applied must be saturated with water for not less than 2 hours prior to application. Alternatively TERRACO TERRABOND ‘A’ or an epoxy primer (TERRACO EPIROK EP 1) must be applied to the substrate and the TERRACO TERRAROC NS 100 placed whilst primer is still wet.
MIXING INSTRUCTIONS
Place 3.5 Litres of cold water (25ºC) in the mixing vessel. Empty entire contents of 25kg bag TERRACO TERRAROC NS 100 into the water whilst mixing with a mechanical mixer. Add additional 500ml water (maximum) to mixture to desired consistency. Mix for 5 minutes and then place or pump.
SPECIFICATION
- Ensure adequate labour is at hand to have continuous mixing and placing of TERRACO TERRAROC NS 100.
- Remove excess water from substrate if saturated with water, if temperature is above 33ºC place grout
immediately after mixing. - When grout is partially set, trim edges and float to desired finish.
Bulking of TERRACO TERRAROC NS 100 for floor screeds:
- TERRACO TERRAROC NS 100 can be bulked using clean silica sand (0.6 – 1.2mm) at a mixing ratio of 1:1
where screeds of between 20 – 50mm are required. - For screeds above 50mm, TERRACO TERRAROC NS 100 can be bulked with clean 10mm graded stone at
the ratio of 1:1. - The stone size should never exceed one third of final thickness of floor.
- When bulking with silica aggregate or stone the quantity of water required will be between 9% and 10%
(4.5 – 5.0 L per 50 kg mix).
CURING
Keep surface damp and covered with plastic sheeting or damp hessian cloth. The surface can also be kept
damp with a fine water spray. The curing must be continuous for 3 days. Care must be taken where grout is
covered by hessian cloth or plastic, ensure that these surfaces are kept damp. On exposed vertical surfaces a
curing compound can be applied.
HEALTH & SAFETY
