Cordek Cellcore HX B Under Beam 18/24 is a 155mm thick polystyrene board used beneath reinforced concrete ground beams and pile caps to protect against the potential effects of ground heave.
HX B (Concrete Ground Beams Protection Block) Grade 18/24 is calculated and calibrated for concrete thickness up to 660mm (has been tested to achieve the specified performance characteristics).
Cellcore HXB (Ground Heave Solution) is a highly-durable, BBA certified product which meets the NHBC’s Technical Standards.
HX B Cellcore 155mm is used to reduce the upward force transmitted to the structure from ground heave (Patented Product Technology).
The standard range of products are available in a variety of depths and grades to suit most commonly encountered combinations of soil heave potential and concrete depth.
Variations of the product are also available for use under pile caps and ground beams or alternatively where integral insulation, permanent formwork or passive gas venting is required.
The depth (85mm, 155mm or 220mm) of the Cellcore HX B panel should be determined by the heave potential of the soil.
One of great things about HX B Under Beam is its very simple to work with and doesn't have much dust off when cut on site.
Grade 18/24 means that safe load is 18 kN/m2 and fail load is 24 kN/m2 (kilonewtons per m2).
Safe load is a maximum safe force that a HX B material offers without fear of breaking.
Fail load is not safe force and will cause permanent deformation of the construction board.
Shrinkage category of 155mm HX B is classified as medium.
155mm Cellcore HX B Under Beam Plasticity index is 20-40.
The cost of manufacturing 155mm cellcore hxb is considered linearly proportional to its grade which is based on maximum concrete depth.
HX B Under Beam Grade 7/10 price is the lowest compared to the higher grades: 9/13, 13/18, 18/24, 24/32 and 32/42.
Cordek Cellcore price list is available upon request.
155mm Cordek Cellcore HX B Under Beam EPS Block Installation:
The procedure for installing Cellcore panels is straightforward.
Please ensure that Cellcore panels are placed upon a suitable firm and level surface.
Typically a layer of concrete blinding beneath the panels is recommended.
The lightweight but durable panels can be easily laid by one person.
Where they are required to be cut this can be carried out using a fine tooth saw or hot wire cutter.
Storage and Handling:
All products are delivered in a polythene wrapping and are clearly labelled.
Both packs of Cellcore and individual panels can be manually handled and offloaded upon delivery, taking in to account any site specific manual handling regulations.
No further storage requirements are needed as the product is unaffected by both UV light and water.

What is 1555mm Cellcore HX B ?
155mm HX B Under Beam is a lightweight enhanced EPS (expanded polystyrene) block designed for use beneath reinforced concrete ground beams and pile caps to protect against the potential effects of ground heave.
How to understand the differences between grades?
Grades are specially calculated and calibrated for deformation of EPS under loading.
7/10 grade | 7 means 7 kN/m2 (safe load) | 10 means 10 kN/m2 (failure load)
9/13 grade | 9 means 9 kN/m2 (safe load) | 13 means 13 kN/m2 (failure load)
13/18 grade | 13 means 13 kN/m2 (safe load) | 18 means 18 kN/m2 (failure load)
18/24 grade | 18means 18 kN/m2 (safe load) | 24 means 24 kN/m2 (failure load)
24/32 grade | 24 means 24 kN/m2 (safe load) | 32 means 32 kN/m2 (failure load)
What HX B under beam safe load means?
HX B Safe Load simply means safe force that a HX B material offers without fear of breaking - Normal Working Load (NWL)
7 means 7 kN/m2 (safe load) – kilonewtons per m2
9 means 9 kN/m2 (safe load) – kilonewtons per m2
13 means 13 kN/m2 (safe load) – kilonewtons per m2
18 means 18 kN/m2 (safe load) – kilonewtons per m2
24 means 24 kN/m2 (safe load) – kilonewtons per m2
What HX B under beam failure load means?
It means the load at which the under slab will fail (permanent deformation).
10 means 10 kN/m2 (failure load) – kilonewtons per m2
13 means 13 kN/m2 (failure load) – kilonewtons per m2
18 means 18 kN/m2 (failure load) – kilonewtons per m2
24 means 24 kN/m2 (failure load) – kilonewtons per m2
32 means 32 kN/m2 (failure load) – kilonewtons per m2
Is it complicated is to work with 155mm HX B Under Beam?
NO, is not. One of great things about 155mm HX B Under Beam is its very simple to work with and doesn't have much dust off when cut on site.
What is the 155mm HX B Under Beam shrinkage category?
Shrinkage category of 155mm HX B is classified as MEDIUM.
What is 155mm HX B Under beam plasticity index?
155mm HX B Under beam Plasticity index is 20-40.
What is the maximum depth of concrete dedicated for 155mm HX B Under beam?
Grades are specially calculated to withstand the load of concrete as per below:
7/10 - from 0mm up to 220mm concrete thickness
9/13 - from 220mm up to 300mm concrete thickness
13/18 - from 300mm up to 460mm concrete thickness
18/24 - from 460mm up to 660mm concrete thickness
24/32 - from 660mm up to 900mm concrete thickness
Why knowing Cellcore grades is so important?
Each grade has adequate strength to support a specified depth of wet concrete during construction and will collapse under its specified fail-load, limiting the upward presssures experienced periods od clay heave.
How to install 155mm HX B Under Beam?
The procedure for installing Cellcore panels is straightforward. Cellcore panels should be placed upon a suitable firm and level surface.
Typically a layer of concrete blinding beneath the panels is recommended.
Panels can be easily laid by one person.
How do cut 155mm HX B Under beam?
Cut can be carried out using a fine tooth saw or hot wire cutter.
How can I joint Cellcore HX B boards?
Individual panels should be butted together, with taping of the joints using the formwork tape to avoid any grout loss between the panels.
Formwork sealing tape, typically 50mm wide is used to seal the joints between adjacent panels. Tape should be used to tape the joints to stop the ingress of concrete slurry weeping down between the panels and cousing a dead spot.
Is Cellcore 155mm HX B Under Beam BBA Certified?
Yes, 155mm HX B Under Beam has BBA Certificate.
Do I need Damp Proof Membrane for Cellcore HX B?
Yes, damp proof membrane should be used either on top or underneath the screed.
Can I walk on 155mm HX B Under Beam ?
No, 155mm HX B is made of moulded collection cellular legs with only 5mm twin fluted polypropylene top which is not strong enough to actually walk on during placement of base spaces and reinforcement.
How to recognize grades on HX B boards?
It is very easy. Each grade has own color code.
They are labeled to easily find on site which grade goes in which area.
7/10 grade is colored RED
9/13 grade is colored BROWN
13/18 grade is colored YELLOW
18/24 grade is colored BLACK
24/32 grade is colored BLUE
The cost of manufacturing Cellcore HX B is considered linearly proportional to its grade. 155mm Cellcore HX B 7/10 price is the lowest compared to the other grades:

INSTALLERS
No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
1. Thermal inspection picture in portfolio
It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.
2. Reviews
Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.
3. Compare prices
Comparing prices will also ensure companies can’t take advantage of you and give you a fair price.
4. Word of Mouth
The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
