75mm Heaveguard Ground Heave Claymaster is an expanded polystyrene board used to protect foundations against effects of ground heave on the inside face of piled ground beams or deep trench fill foundations.
Heaveguard (claymaster) works by surrounding the pile cap with a layer of low density, compressible, expanded polystyrene, reducing pressure on the ground beams as the surrounding clay expands and contracts.
Cordek Heaveguard 75mm is a highly-durable, BBA certified product which does not compress significantly until loads exceed 20 kN/m2.
A load of 40 kN/m2 is needed to produce 50% compression of the Heaveguard material, that's why it is not recommended for use under ground floor slabs, piled beams or pile caps.
This green coloured cordek claymaster board comes in standard size 2400mm x 1200mm x 75mm to allow easy installation and reduce the lateral force transmitted to the structure.
Available in 50mm, 75mm, 100mm, 200mm and 300mm thick to suit most commonly encountered combinations on site.

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.
