Description
High Performance Concrete for Bases, Paths and Repairs
High Performance Concrete combines straightforward preparation with a compressive strength of 40 N/mm² after 28 days. Factory-produced for consistent quality, it is suitable for a range of internal and external concreting projects.
Use it for shed and greenhouse bases, pathways, steps, maintenance and repairs. It can also be used for structural concrete applications where its specification meets the project’s requirements.
Suitable Applications
- Concrete bases for sheds and greenhouses.
- Paths and steps.
- Maintenance and repair projects.
- Internal and external concreting.
- Structural applications where the specified concrete requirements are met.
Key Features
- 40 N/mm² strength after 28 days: suitable for projects requiring this level of compressive strength.
- Factory-produced quality: a consistent blend from bag to bag.
- Flexible mixing options: mix by hand or with a traditional mechanical mixer.
- Internal and external use: suitable for a variety of project locations.
- Protective packaging: supplied in showerproof, recyclable plastic bags.

Mixing and Application Guidance
Prepare the work area before mixing. Remove loose material and ensure surfaces are free from oil and grease.
Add approximately 2–2.6 litres of clean water per 20kg bag and mix by hand or with a traditional concrete mixer. Avoid overmixing or adding excessive water, as this can reduce strength, bond and durability and cause cracking. All required dry components are included; do not add other products or materials.
This concrete is fast-setting and should be used within 30 minutes of adding water. Fully compact it before finishing. Do not add more water or remix to restore workability after the initial set.
After placing, protect the concrete from drying out by covering it with a suitable material, such as polythene or wet hessian.
For structural applications, confirm that the product meets your project’s specified requirements.
Storage
Store unopened bags in cool, dry conditions, raised off the ground on a pallet or shelf and protected from wind and rain.
