Product Information

Full details

The B&Q All In Ballast is a pre-blended mixture of sand and stone aggregate designed for DIY enthusiasts and construction professionals looking to create reliable concrete. Its primary benefit is the convenience of having a balanced mix ready for immediate use, which simplifies the production of foundations, footings, and shed bases. However, users should be aware that because it is a natural product, color and stone grading may vary slightly between bags, necessitating careful batch management to maintain consistency.

FAQs

What is the recommended mixing ratio?

A standard ratio is typically 1:6 (one part cement to six parts ballast), but always adjust based on the specific load-bearing requirements of your project.

Can I use this for decorative concrete?

No, this product is intended for structural concrete. The aggregate size is too coarse for decorative finishes.

How many bags do I need for my shed base?

This depends on the volume of your area (length x width x depth). It is recommended to calculate the cubic meter requirements and consult a concrete calculator for precise bag counts.

Is this product suitable for indoor use?

While it can be used indoors, ensure the area is well-ventilated and that you are prepared for the mess associated with mixing heavy aggregates.

Why does the color of the stone look different between bags?

This is a natural product extracted from different locations. Variations in color and grading are normal and expected.

Troubleshooting

Concrete is cracking after drying

This is often caused by using too much water or not curing the concrete slowly enough. Ensure you cover the pour with plastic or dampen it occasionally during the curing process.

Mix feels too sandy or gritty

Check your mixing ratios. If the mix lacks structural strength, you may need to increase the cement ratio or ensure the ballast was thoroughly mixed before adding water.

Setup, Compatibility & Care

Mixing Instructions

  1. Ensure you have a clean mixing board or a mechanical cement mixer.
  2. Add the ballast and the required amount of cement in the correct proportions.
  3. Slowly add water while mixing until you achieve a consistent, workable concrete consistency that is not too runny.

Compatibility

This product is compatible with all standard Portland cements. If you are working in cold weather, consider using an accelerator additive to ensure proper curing.

Care and Storage

Store bags in a dry, covered area off the ground to prevent moisture ingress, which can cause the material to clump or harden inside the bag.
