There comes a point at which enough projects have been delivered, explosive trials planned, conducted and reported on and novel products developed, with all the associated efforts and hurdles to be crossed, that the experience has a value to others. The important thing is that this is done impartiality and with discretion, whether covered by NDA or not.
SJH Projects has been built up a lot of practical experience with a wide variety of customers, both small and large, in the UK and abroad. Different sectors have their own cultures and work patterns. The lone inventor needing some advice on what issues lay ahead, is very different to a multi-national, major defence contractor running a nationally important vehicle test programme.
Some projects are shown on our website. Many more are not, but the depth of knowledge garnered over many years is available to help future customers and their projects may or may not appear here in the future.
SJH Projects supports organisations in assessing the blast vulnerability of their buildings and facilities. Drawing on extensive experience testing building components, particularly glazing, and combining this with advanced blast overpressure modelling, we help you understand the level of risk your site may face. This includes identifying the safe stand‑off distances required to protect people and assets, as well as advising on any additional blast‑mitigation measures that may be necessary.
Historically, Hostile Vehicle Mitigation (HVM) has focused on stopping a Vehicle‑Borne Improvised Explosive Device (VBIED) from breaching a protected perimeter. Because blast overpressure decreases rapidly with distance, keeping a potential explosive threat as far from people and buildings as possible has long been the most effective protective strategy where space allows.
More recently, attacks across Europe have shown a shift in tactics. Vehicles are now being used as simple but highly effective weapons to target crowded public areas. These low‑tech attacks can cause significant harm without the need for explosives, and in some cases the assault continues on foot after the vehicle is stopped or disabled. This change has made pedestrian‑area protection and multi‑layered security planning increasingly important.
If you’re facing a complex blast related challenge, SJH Projects offers specialist support grounded in a long history of innovative design within the protection and security sectors. Our team provides professional, impartial and fully confidential guidance, helping you explore solutions related to design, materials, suppliers and operational procedures.
We have delivered case studies for a wide range of clients, including technology reviews, market surveys, and concept development tailored to specific performance or regulatory requirements.
