300mm Cellcore HG Grade 50/65 is a lightweight expanded polystyrene (EPS) insulation board designed for use in ground heave protection applications where the specification of the project mean that the standard Cellcore HX S Under Floor Slabs and Cellcore HX B Under Ground Beams products are not suitable.
Cellcore HG 50/65 is calculated and calibrated for concrete thickness up to 1940mm to provide protection against vertical heave under floor slabs, ground beams and pile caps.
300mm Cordek Cellcore HG is available in 3 special grades: 30/40, 40/50 and 50/65 to suit most commonly encountered combinations of soil heave potential and concrete depth from 900mm up to 1940mm!
One of great things about 300mm Cordek Cellcore HG is its very simple to work with and doesn't have much dust off when cut on site.
Grade 50/65 means that safe load is 50 kN/m2 and fail load is 65 kN/m2 (kilonewtons per m2).
Safe load is a maximum safe force that a HG material offers without fear of breaking.
Fail load is not safe force and will cause permanent deformation of the product.
Shrinkage category of 300mm Cellcore HG is classified as high with 40-60 plasticity index.
· Suitable for use beneath deep slabs, ground beams and pile caps up to 1940mm in depth.
· Reduces the upward force transmitted to the structure from ground heave.

The procedure for installing Cellcore HG panels is straightforward.
Please ensure that Cellcore HG boards 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 HG 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 300mm Cellcore HG?
Cellcore HG is a lightweight expanded polystyrene (EPS) insulation board designed for use in ground heave protection applications where the specification of the project mean that the standard Cellcore HX S Under Floor Slabs and Cellcore HX B Under Ground Beams products are not suitable.
Can I use Cellcore HG for concrete less then 900mm in thickness?
Yes, it is still possible but Cellcore HG is a type of collapsible void former designed for concrete thickness from 900mm up to 1140mm. Please refer to HX S Under slab grade 24/32 designed for concrete depth between 660mm and 900mm.
How to understand the differences between grades?
Grades are specially calculated and calibrated for deformation of EPS under loading.
30/40 grade | 30 means 30 kN/m2 (safe load) | 40 means 40 kN/m2 (failure load)
40/50 grade | 40 means 40 kN/m2 (safe load) | 50 means 50 kN/m2 (failure load)
50/65 grade | 50 means 50kN/m2 (safe load) | 65 means 65 kN/m2 (failure load)
What HG under slab safe load means?
HG Safe Load simply means safe force that a HG material offers without fear of breaking - Normal Working Load (NWL)
30 means 30 kN/m2 (safe load) – kilonewtons per m2
40 means 40 kN/m2 (safe load) – kilonewtons per m2
50 means 50 kN/m2 (safe load) – kilonewtons per m2
What HG under slab failure load means?
It means the load at which the under slab will fail (permanent deformation).
40 means 40 kN/m2 (failure load) – kilonewtons per m2
50 means 50 kN/m2 (failure load) – kilonewtons per m2
65 means 65 kN/m2 (failure load) – kilonewtons per m2
Is it complicated is to work with 300mm HG Under Slab?
NO, is not. One of great things about 300mm HG Under Slab is its very simple to work with and doesn't have much dust off when cut on site.
What is the 300mm HG Under Slab shrinkage category?
Shrinkage category of 300mm HG under slab is classified as HIGH.
What is 300mm HG Under Slab plasticity index?
300mm HG Under Slab Plasticity index is 40-60.
What is the standard size of 300mm HG Under Slab?
HG Under Slab dimensions are:
2,400mm x 1,200mm (8’x4’)
What is the maximum depth of concrete dedicated for 300mm HG Under Slab?
Grades are specially calculated to withstand the load of concrete as per below:
30/40 - from 0mm up to 1140mm concrete thickness
40/50 - from 1140mm up to 1540mm concrete thickness
50/65 - from 1540mm up to 1940mm 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 300mm HG Under Slab?
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 300mm HG Under Slab?
Cut can be carried out using a fine tooth saw or hot wire cutter.
How can I joint Cellcore HG Under Slab 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 300mm HG Under Slab BBA Certified?
Yes, 200mm HG Under Slab has BBA Certificate.
Do I need Damp Proof Membrane for Cellcore HG?
Yes, damp proof membrane should be used on top of the slap and underneath the screed.
Can I walk on 300mm HG Under Slab ?
Yes, 300mm HG is made of moulded collection cellular legs with twin fluted polypropylene top which is strong enough to actually walk on during placement of base spaces and reinforcement.
How to recognize grades on HG 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.

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.
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.
We are the stockist of construction materials and related products for both trade and DIY from most recognizable brands in the UK like Cordek, RCM, Promat, Rockwool, Isover, Celotex, Xtratherm, Ursa, Low-E, Cedral, Kingspan, Dufaylite, British Gypsum, K-rend, Ecotherm, Iko enertherm, Kay-Metzeler, Terrawool to allow you to complete your insulation job on time at competitive prices and the highest standards.
