SikaGrout 510 (was Parex CS Grout)

£17.59

Tax excluded

£21.11 Tax incl.

Used for: Precision high-performance grouting, bedding joints, sealing, & anchoring steel reinforcements, and more.

SikaGrout 510 (previously known as Parex CS Grout) is a high flow, non-shrink, high rapid strength, versatile (consistency can be adjusted), cementitious grout with sustainability benefits.

By simply adjusting the water content, different consistencies (liquid, plastic, & mortar) can be achieved to suit a range of applications. Once placed it achieves rapid strength development, structural support, and good vibration resistance.

Highly versatile this product is ideal for a range of applications from grouting beneath machine bases & dowel bars between precast concrete, to bedding joints, sealing penetrations, and fixing anchor bars & ground anchors.

Delivery policy - We aim to ship all products same day where possible (Orders must be placed before 12pm)

SikaGrout 510 CS High Flow (previously Parex CS Grout) is a one-part, cementitious Product achieving rapid strength development, high ultimate strength, high flow and non-shrink properties.

Typical uses include:

Crane & transport rail tracks	Stanchion bases	Machine & Turbine bed plates
Dowel bars between precast concrete units	Bedding precats concrete units	Ground anchors, starter bars & bolts
Bridge bearing supports	Repairing concrete structures & components	Void filling
Steel reinforcement anchoring	Sealing around penetrations	Grouting beneath structural steelwork

Easy to mix & apply, needing to only be mixed with water, its consistency is adjustable to ensure the perfect flow characteristics for your project. It is pumpable and pourable for application thicknesses from 10-100mm. High strength, non-shrink, non-metallic and ‘chloride free’ it is extremely durable with no segregation or bleeding, low permeability, and low water absorption.

SikaGrout 510 is also non-corrosive, resistant to sea water and milk alkali attack with a EuroClass A1 reaction to fire. It holds CE mark 1504-3 (‘Products and systems for the protection and repair of concrete structures – Structural and non-structural repair’) and CE mark 1504-6 (‘Products and systems for the protection and repair of concrete structures – Anchoring reinforcing steel bars’).

Application Guide

Substrate Preparation

The substrate should be prepared by suitable mechanical preparation techniques such as high pressure water jetting, breakers, blastcleaning, scabblers, etc. The concrete substrates should be pre-soaked with clean water continuously for 2 to 6 hours to ensure a saturated surface dry (SSD) condition throughout the operation. Immediately before pouring the grout, remove all excess or standing water from within any formwork, cavities or pockets.

Shutter/Formwork

All formwork should be of adequate strength, treated with release agent and sealed to prevent leakage. Sealing can be achieved by using Sikaflex® -11FC+ sealant beneath or around formwork and between joints. Ensure formwork includes outlets for extraction of the pre-soaking water. A header box / hopper should be constructed on one side of the formwork so that a grout head of 150 - 200 mm can be maintained during the grouting operation.

Mixing

Varying consistencies are achievable using the following water contents per 25 kg bag:

Pourable Mortar ~3.6 litres
Flowable / Plastic Mortar ~4.3 litres
Fluid / Liquid Grout ~4.8 litres
NOTE: The maximum water content shall be 4.8 litres per 25 kg bag.

Measure the appropriate amount of clean, potable water (if necessary, warm water to achieve a temperature between +15 and +20oC) to achieve the desired grout consistency given in the aforementioned table and pour into a clean, suitable mixing vessel for each complete unit of SikaGrout®-510 CS High Flow to be used. Flexible mixing vessels (e.g. 'gorilla tubs') are unsuitable - rigid vessels shall be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque, slow speed (i.e. 200 to 500 rpm) drill with an appropriate grout stirrer, or a grout mixer set on slow speed for small mixes. The use of a drill and paddle (in most circumstances) is only suitable for mixing one bag at a time. For larger mixes, use forced action type mixers (NOT concrete tumble mixers which do NOT apply sufficient shear, NOR high speed or colloidal mixers, as these may cause thixotropy, leading to loss of flow). This Product is NOT suitable for mixing by hand. If using a drill and paddle, keep the mixing head in the material - refrain from lifting in and out, as this will introduce air. It is of utmost importance that the Product is mixed thoroughly to the desired consistency (i.e. for at least 3 minutes). Fresh grout (particularly at the highest water level) should be allowed to stand until the air entrapped by mixing has been released before application (typically 1 to 2 minutes).

Application

Immediately after mixing, and after the Product has been allowed to de-gas (which typically takes between 1 and 2 minutes), pour the mixed grout from one side of the formwork through the header box / hopper, ensuring continuous grout flow during the complete grouting operation to avoid trapping air. Keep header boxes / hoppers topped up for the duration of the application. Continue until the grout appears at the opposite side of the grouting area to the header box / hopper. Use steel banding or chains to assist flow where necessary. Do NOT disturb once grouting has been completed. For large volume placement, grout mixers and pumps are recommended (e.g. Putzmeister SP11 TMR).

Curing Treatment

After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’. Placed grout, which is exposed, should be cured in accordance with good concrete practice. Protect the fresh material from premature drying using an approved curing method (e.g. curing compound such as Sikafloor® ProSeal, moist geotextile membrane, hessian, polythene sheet, under water, etc.). In cold weather, apply insulating blankets or heated curing blankets to protect the Product and maintain a satisfactory constant temperature.
