Description

Nitocote CM210 two-component polymer modifi ed cementitious coating is supplied in pre-packaged form. The product is designed to be easily mixed on site using a slow speed drill fi tted with a mixing paddle and then applied to the substrate using either brush, trowel or spray. Roller application may also be used, however, fi nishing the surface with a trowel is recommended for best results.

Application instructions

Instructions for use

Surface preparation

All surfaces which are to receive the coating, must be free from oil, laitance, grease, wax, dirt or any other form of foreign matter which could affect adhesion. Typically, concrete surfaces can be cleaned using a high pressure water jet or grit blasting or wire brushing or mechanical grinding to achieve proper adhesion between the concrete surface and coatings.

Spalled surfaces or those containing large blowholes, and other such defects, should be repaired using Nitocote CM210 or a Fosroc approved repair mortar. Care must be taken when choosing the repair mortar to ensure that it has all necessary approvals for contact with potable water.

If the surface contains small blowholes, typically less than 1 mm wide, the coating can be applied directly onto the substrate without the need for a treatment. Elastrometric Cementitius Waterproofing Coating.
  

Uses

Conbextra GP2 is used for precision grouting where it is essential to withstand static and dynamic loads. Typical applications would be the grouting of base plates of turbines, compressors, boiler feed pumps etc., It can also be used for anchoring a wide range of fi xings. These include masts, anchor bolts and fence posts.

Advantages

• Gaseous expansion system compensates for shrinkage and settlement in the plastic state 
• No metallic iron content to cause staining 
• Pre-packed material overcomes onsite batching variations 
• Develops high early strength without the use of chlorides 
• High ultimate strength ensure the durability of the hardened grout 
• Free flow ensures high level of contact with load bearing area.

Standard Compliance

Conbextra GP2 conforms to ASTM C1107 (Standard Specifi cation for Packaged Dry, Hydraulic-Cement Grout (Non-shrink). 

Description

Conbextra GP2 is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free fl owing, non-shrink grout for gap thicknesses up to 100mm. Conbextra GP2 is a blend of Portland cement, graded fi llers and chemical additives which impart controlled expansion in the plastic state whilst minimising water demand. The low water demand ensures high early strength. The graded fi llers are designed to assist uniform mixing and produce a consistent grout.

Technical Support

An experienced technical advisory team is available to give technical service on request.

Specification Clauses

Performance specification

All grouting shown on the drawing must be carried out with a pre packed cement based product which is chloride free. It shall be mixed with clean water to the required consistency. The grout must not bleed or segregate. A positive volumetric expansion shall occur while the grout is plastic by means of gaseous system.

Typical detail of stanchion base plate

The compressive strength of the grout must exceed 50 N/mm2 at 7 days and 60 N/mm2 at 28 days. The fl exural strength of grout must exceed 9N/mm2 @ 28 days. The fresh wet density of the mixed grout must exceed 2150 kg/m3 . The storage, handling and placement of the grout must be in strict accordance with the manufacturer’s instructions. 

Application instructions

Preparation

Foundation surface

The substrate surface must be free from oil, grease or any loosely adherent material. If the concrete surface is defective or has laitence, it must be cut back to a sound base. Bolt holes and fi xing pockets must be blown clean of any dirt or debris.

Pre-soaking

Several hours prior to placing, the concrete substrates should be saturated with fresh water. Immediately before grouting takes place any free water should be removed with particular care being taken to blow out all bolt holes and pockets.

Base plate

It is essential that this is clean and free from oil, grease or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots.

Levelling shims

If these are to be removed after the grout has hardened, they should be treated with a thin layer of grease.

Formwork

The formwork should be constructed to be leakproof. This can be achieved by using foam rubber strip or mastic sealant beneath the constructed formwork and between joints.

In some cases it is practical to use a sacrifi cial semi-dry sand and cement formwork. The formwork should include outlets for pre-soaking.

Uses

For the rapid temporary patching and plugging of concrete segments, concrete and brick tunnel linings, sewage systems, below ground access chambers, pipes, basements, foundations and mines. 

Advantages

• Emergency water - stopping capability
• Single component - only the addition of clean water is required.
• Excellent bond to the substrate 
• Low exotherm minimises thermal cracking 
• Pre-packed formulation to overcome variation in site batching 
• Contains no chloride admixtures.

Description

Renderoc Plug is supplied as a ready to use blend of dry powders which requires only the addition of clean water at site to produce a highly consistent, rapid setting mortar which is easy to apply in many diffi cult conditions. The material is based on a blend of cements, graded aggregates, special fi llers and chemical additives which control the rate of set and minimise the risk of thermal cracking.  

Technical Support

Fosroc off ers a comprehensive range of high performance, high quality concrete repair and construction products. In addition, Fosroc off ers technical support service to specifi ers, end users and contractors, as well as on-site technical assistance in locations all over the country. 

Design criteria

Renderoc Plug can be applied to horizontal, vertical or overhead surface at a wide range of thickness. Generally, the volume of mixed material used in a single application is restricted to that which can be applied by trowel or gloved hand. Thicker sections can be built up in layers. If any doubt arises about the nature of the substrate, consult the local Fosroc offi ce for further information.

Specifi cation clauses
Water stopping mortar

The water stopping mortar shall be Renderoc Plug, a single component cement based product to which only the site -addition of clean water shall be permitted. It must be chloride free and shall have a low exotherm to minimise thermal cracking. 
 
Application instructions

Preparation

Areas to be patched should be cut back to a depth of 15mm and given a good mechanical key. Feather edges must not be allowed. Surface should be brushed clean to remove loose material, dust and laitance. Grease, slime or mould growth should be removed by steam cleaning or high pressure water jetting. A proprietary degreasing agent should be used for removal of light oil or grease contamination.

To seal leaks, crack openings must be chased out to approximately 20mm. The chase should always be undercut to avoid leaving a V-section. All loose material and debris should be removed.

Mixing

Renderoc Plug should be added to clean water in the following proportions : 

One part clean water : 3 parts Renderoc Plug ( measured by volume ).

Mix to a stiff consistency in a suitable container using a trowel or gloved hand. Due to the rapid set characteristics of the product, only prepare a quantity of mortar which can be placed within the prescribed set time.

Application

Trowel apply or hand-knead the mixed mortar in place, ensuring maximum contact with the substrate before the material sets. If being used to plug running water, Renderoc Plug should be used and held in place until the initial set is reached. 

Cleaning

Renderoc Plug should be removed from tools, equipment and mixers with clean water prior to the initial set. Cured material can only be removed mechanically.
