Terraco Terraroc NS 100

Terraco Terraroc NS 100

Product Overview

- Terraroc NS 100 is a general purpose cementitious non-shrink 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 determines its wide range of applications.

- Due to its early strength development it allows for quick return to service of grouted areas.

Properties

- Early strength development.

- Non-shrink.

- Can be poured or pumped.

- High compressive strength.

- Chloride free.

- Extensive workability.

Areas Of Use

- Narrowing void grouting (flow-able 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.

Application Method

Preparation of Surface

- 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 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 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 Terraroc NS 100 into the water whilst mixing with a mechanical mixer.

- Add additional 500ml water (maximum) to mixture to desired consistency.

Specification

- Ensure adequate labour is at hand to have continuous mixing and placing of 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 Terraroc NS 100 for floor screeds: a) 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. b) For screeds above 50mm, Terraroc NS 100 can be bulked with clean 10mm graded stone at the ratio of 1:1. c) 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.
