Blockwalls solution provides the density required to store X-Ray equipment safely

Stackabloc has the density required to protect people from the storage of company’s X-Ray equipment.

ITCL are the market leader in the pipeline inspection market. Offering consultancy services including phased array, eddy current array, tube inspection and ultrasonic inspection.

A recent investment in radiography technology used to identify the integrity of pipelines has meant the business needed to build an inhouse X-Ray Laboratory and Dark Room. Given the time constraints on the project and the density required to safely contain such equipment, Director Mike Dodd tasked a local business Blockwalls to provide a solution.


ITCL are based in a series of industrial units in Ellesmere Port; close to Stanlow Oil Refinery. Their range of inspection techniques and methods test the integrity and material hardness of industrial plant and pipelines. The use of radiography is an emerging technique which is particularly good at detecting volumetric flaws, including voids, gas pores and solid inclusions. ITCL have taken a strategic decision to invest in specialist equipment and therefore required a dedicated X-Ray Suite and Dark Room to be built with the sufficient wall density of 750mm in order to contain the X-Ray and Gamma X-Rays when the equipment is in use.


Seventy Stackabloc blocks were delivered and installed within a few days of placing the order building a “Concrete block Dark room” . The area and design of the space was agreed with ITCL; and following a quick calculation a CAD drawing was produced.

From a health and safety perspective the Virtabloc wall has provided a solid and reliable solution, creating an effective working environment in next to no time.

Benefits realised by ITCL included;

  • Speed of construction
  • Cost saving of 24% on materials and labour when compared to a traditional solid wall build
  • The density specification met the requirements of the X-Ray manufacturer so it was fit for purpose
  • The manufacturing process utilises 87% recycled material which fits with the ITCL ethos and positive attitude towards sustainable solutions


Working in partnership with structural engineers and civil engineering contractors.

We come from the civil engineering sector and have invested in the development of advanced concrete technology and quality assurance. Our mission is to support structural engineers and civil engineering contractor to come up with innovative solutions to common problems. Block Walls are the ideal solution for structural engineers and civil contractors who are seeking cost effective solutions to properly manage their projects.


You send us a basic description or drawing of the area you need to construct and a description of the operation. We will do the rest.


1. Our design team will establish which specification will best fit your environment and calculate the number of blocks required to do the job

2. We quote, you order, we make

3. We deliver


We offer a full design service from simply working out how many blocks you require for your project to full design including drawings and calculations.

Our full design service can include:

  • Planning applications
  • Structural engineering design and calculations
  • 2D and 3D CAD drawings and BIM models
  • Building regulation applications
  • Full project management services

ITCL Director Mike Dodd commented:

“The Blockwalls solution was not only cost effective but delivered the density and speed of construction we needed in order to house the X-Ray equipment.” He added “Clearly we do not fit the typical customer profile for Block Walls however we have proved the versatility of what is essentially a concrete block made from recycled aggregates.”

Block Walls Managing Director Bob Evans adds. “This project has demonstrated the flexibility of what is a simple idea. As a result we are exploring other applications for both our Virtablok and Stackabloc products and testing other waste streams such as glass and ash to produce a geopolymer concrete.”

Each block saves 105kg of carbon due to using recycled material. This is equivalent to an average car journey of 262 miles
