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. Mix for 5 minutes and then place or pump. 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.
