If kept dry and stored in original condition, ACS Grout HES30 will keep for up to 6 months. The shelf life of the product may reduce if it is subjected to high temperatures and humidity.

Surface Preparation

All substrates should be sound, clean and free from dust, oil, or any other surface contaminants such as curing compounds and release agents. All bolt holes and fixing pockets must be cleaned out using compressed air. To maximise adhesion, we recommend that surfaces be abraded or roughened, by mechanical means such as needle gun, grit blasting or grinding.

After preparation is complete, saturate the surface with clean water for a minimum of four hours prior to grouting. Care should be taken to remove all surplus water prior to grouting.

Formwork

As ACS Grout HES30 can be used as a free flowing grout, it is important to construct the formwork to be leakproof. Formwork should also be built so that a grout head above the level of the underside of the base plate is maintained. This will allow gravity flow to completely fill the void to be grouted.

To allow easy removal of the forms, coat the formwork with oil and ensure adequate air holes are installed.

Mixing

ACS Grout HES30 should be mixed using a high speed drill and spiral mixer, mechanical grout mixer, or a suitable high sheer drum mixer. DO NOT MIX MATERIAL BY HAND.

Because continuous grout flow is essential, ensure that the mixing method and labour is sufficient to enable continuity of the operation.

1. Add the correctly measured water content into the mixing vessel. To achieve the selected consistencies the amount of clean water to be added per 20kg bag is shown in the downloadable TDS.
2.  Slowly add the total dry contents of the ACS Grout HES30 bag and mix continuously for five minutes until a smooth and even consistency is obtained. Allow the mixture to stand so any entrapped air can escape. If a mix has become unworkable because of time delays, do not add additional water to increase flow of the grout – discard the mix and start again.

Placement

The mixed grout should be placed immediately. ACS Grout HES30 can be placed in thicknesses from 10 to 125mm. Continuous grout flow is essential.

Pour the mixed grout from one side of the void only to eliminate entrapment of air. The pouring side should be raised by means of a hopper or grout box to maintain a grout head at all times.

For larger applications ACS Grout HES30 can be placed by means of pumping.

For maximum performance it is important to maintain the grout, base concrete and steel substrates within a temperature range of 18 – 25ºC prior to, during and for 48 hours following placement of the grout.

Grouting should not take place if the temperature is 5°C or lower. Warm water can be used to accelerate strength development during colder weather.

When temperatures exceed 30ºC, grouting should be sheltered from the heat or conducted early morning. Where possible, keep materials cool and use cold water in the mix.

Do not submerge grout for 2 hrs post placing.

It is necessary to cure all exposed surfaces. The use of a concrete curing membrane, hessian or continuous water spray is recommended.

All tools should be rinsed with water immediately after use to remove all traces of ACS Grout HES.

During use, avoid inhalation of dust and contact with the skin and eyes. Wear suitable clothing, gloves, eye protection and respiratory protective equipment.

If contact with the skin occurs, thoroughly clean the area with plenty of fresh water and soap. In case of contact with the eyes rinse with plenty of fresh water and seek medical advice.

If swallowed, seek medical attention immediately – do not induce vomiting.
