In December 2019, we attended and exhibited at the International Security Expo (ISE) at Olympia, London. Joining the likes of the Metropolitan Police and Department for International Trade Defence and Security Organisation, it is a great opportunity to showcase the innovative and unique security solutions that RWS offers on both a national and international scale.
Whilst at the ISE, we were asked very similar questions by security experts and senior decision makers from Government, Law Enforcement, Military and Transport & Borders, and others. To provide more information on the BBX block, we’ve expanded on the five most common questions below in order to expand your knowledge of BBX Blocks, and help you make the best decision for your organisation and premises.

1. How can the BBX block protect against both blast and ballistics?
The BBX Block has been developed alongside industry experts, Tarmac. Tarmac has provided a range of services to the UK construction sector across different sectors and applications. The unique composition of the BBX Block makes it one-of-a-kind in the industry, and there isn’t any other material on the market that matches it. Rigorous testing to Home Office and BSI standards backs up our claims that it is protective against both blast and ballistics.
Blast testing:
- Tested against a blast of 100kg TNT, equivalent to simulate a Vehicle Bourne Improvised Device (VBIED), BBX achieved the following ratings:
- 100mm block achieved C25 (25 metre standoff)
- 215mm block achieved C15
Ballistics testing:
- The mortar is to be a maximum of 3mm to maintain bullet resistance.
- 100mm block –.44” Magnum/.357” Magnum – BR4
- 140mm block –7.62x51mm/5.56x45mm – BR6
- 215mm & 280mm block –7.62x51mm AP (HC) – BR7
Overall In real terms, this means protection of employees and equipment that standard CMU blocks cannot offer.

2. What is it made from?
Due to the sensitive nature in which the BBX Block is applied in security situations, and its unique composition, we cannot disclose exactly what the block is made from. Extensive research has gone into the development of the BBX Block from industry experts. Research and development to create the very best composition, that can be installed using normal construction materials and tools ensures that maximum security and protection is provided to property and people.
3. How much does it cost?
Because of its unique nature, combined ballistic and blast protection, and rigorous tests, you could assume that BBX Blocks are more expensive than other blast or ballistic protection instalments. However, on average, it actually works out around 20% cheaper than standard systems, and because it doesn’t require any specialist installation, it’s a cost-effective choice for security-conscious organisations.
4. What is the lead time like for the BBX Block?
For most of the year, there is a maximum lead time of four weeks, from order to distribution to delivery. This is very competitive in comparison with the rest of the market and means you can increase and improve your security in under a month. The only time this would be increased is across the Christmas period. We can also be flexible to meet your organisation’s specific needs – do get in touch for a more in-depth discussion about how we can help.
5. What is the construction method?
The construction method for the BBX Block is quicker than standard-density blocks. BBX is a highly-adaptable modular building system. It’s flexible and can be designed to any size or specification. We can also install our blast- and bullet-resistant glazing systems within the BBX structure to create truly-secure building solutions. The simplified nature of BBX Block’s singular blast and ballistic system also gives designers more freedom with regards to the layout and structure.
