About the site

Cromhall Quarry has 9.5 acres of water and is only 1.5 miles from J14 of the M5.

The slightly undulating rock bottom gives an ideal training depth of 17 metres. It slopes upwards to the former haul road entry, giving a shallow beach area allowing easy access and egress for entry-level dive trainees and rescue training.

Cromhall Diving

At the north end of the quarry is a pontoon floating in 15 metres of water that has been specifically designed for ease of use by divers.

The former limestone quarry has filled naturally, with underwater visibility during April 2012 of up to 5-6 metres, which is expected to rise to 8-10 metres during the Summer.

The water quality when sampled at the beach area on the 4th September 2015 was Excellent with respect to “Water Resources, The Bathing Water Regulations, 2008 No 1097” (E coli & Enterococci Nil).

The site is unique - it is home to EU-protected Great Crested Newts (click here to find out more about the newts), and is a Site of Special Scientific Interest containing, among other fossils, the Cromhall dinosaur.

Explore the Gun Turret

Cromhall Diving

Cromhall Diving Centre has sunk an ex Royal Navy decommissioned Mk 8 4.5" Gun Shield (Turret) - pictured in the process of being submerged.

The fibreglass gun shields were fitted for weather protection on Frigates and Destroyers.

They have now been superseded with more angular gun shields to reduce radar signatures.

The decommissioned shield has been cleaned and sunk for divers to enter, with a dummy gun barrel!

The gun shield has joined shipping containers, a few phone boxes, a number of boats, and an aircraft cockpit.

Nitrox/Trimix Continuous Blending

Cromhall Diving Centre use the LM-NT Continuous Process blending systems that supply pre-mixed low pressure O2/He to the compressor for direct filling of diving cylinders with Nitrox (max 40%) and Trimix.

Cromhall Diving

The diving cylinders do not need to be oxygen cleaned to fill with this process and the system eliminates the risks of partial pressure blending.

For sales and service contact the quarry or for more info visit: www.nitrox-trimix.com

Gas Filling

Double filtered Air is available to 232 bar, as well as Nitrox/Trimix & 100% O2.

With our continuous blending system we do not require your cylinders to be O2 clean for mixes to a maximum of 40% Nitrox.

Cylinders to be filled with mixes greater than 40% O2 are required to be O2 Clean.

We reserve the right to refuse to fill any cylinder that appears to be suspect in any matter, we shall refuse to fill any cylinder without a valid test marking.
