Frequently Asked Questions about Argex

What makes Argex different from standard aggregates?

Argex expanded clay is up to 5 times lighter than traditional aggregates while maintaining excellent structural properties. It's manufactured by heating natural clay to 1200°C, creating a honeycomb structure that provides insulation, drainage, and load-bearing capabilities. We stock various grades at our Thatcham depot suitable for different applications.

How much Argex do I need for my project?

Coverage depends on the application and grade used. As a guide: for drainage layers use 100-150mm depth, for lightweight fill calculate 0.3-0.4 tonnes per m³. Our Thatcham team can help calculate exact quantities for your project. Call 01635 865679 for expert advice.

Can I collect Argex from your Thatcham depot today?

Yes, we typically have Argex 4-8mm and 8-16mm grades in stock for immediate collection from our Thatcham depot. We recommend calling ahead on 01635 865679 to confirm availability and arrange loading. We're open Monday-Friday 7:00am-4:30pm and Saturday 8:00am-12:00pm.
