Description
High Performance Grout for Void Filling and Structural Applications
High Performance Grout combines modified cements and aggregates to produce a strong, durable, non-shrink grout. Factory-produced for consistent quality, it offers excellent levelling and penetration for demanding construction applications.
The mix can be prepared for dry packing, trowelling or high-flow application by adjusting the water quantity within the specified limits. In its high-flow form, it can be pumped or poured to fill gaps and voids.
Suitable Applications
- Filling voids.
- Sealing joints.
- Reinforcing existing structures.
- Sealing openings in surfaces.
- Internal and external grouting.
Key Features
- Non-shrink formulation: designed for construction grouting applications.
- High compressive strength: achieves 60 N/mm² after 28 days.
- High flow and penetration: suitable for pouring or pumping at the specified high-flow consistency.
- Flexible preparation: water quantities are specified for dry packing, trowelling and high-flow use.
- 10–200mm gap thickness: suitable for a range of filling requirements.
- 20kg bags: all required dry components are included; simply add water.

Mixing Guidance
Use a mechanical mixing method, such as a grout mixer. Select the water quantity for the intended application:
- Dry packing: approximately 2–2.5 litres per 20kg bag.
- Trowelling: approximately 3–3.5 litres per 20kg bag.
- High-flow pouring or pumping: approximately 4–4.5 litres per 20kg bag.
Mix for approximately 3 minutes until a uniform consistency is achieved. All required dry components are included; do not add other materials.
Use within 10 minutes of mixing for dry packing, or within 30 minutes for trowelling and high-flow applications. Do not remix or add water to extend workability.
Application Guidance
Use for gaps between 10mm and 200mm, following the project specification and Product Data Sheet. Apply at temperatures between +5°C and +30°C.
Setting times vary with temperature and other environmental conditions. The stated application times above should guide preparation and placement.
Storage
Store unopened bags in cool, dry conditions, raised off the ground on a pallet or shelf and protected from wind and rain.
