Our Vision, Mission and Values
"We're continually carrying out research and development, allowing us to reflect an ever-changing building industry. It's this focus and our ongoing investment in block manufacturing facilities that will make sure we keep on exceeding customer expectations.
Corporate Responsibility
To help you make an informed decision about the products that you use, we have developed a guide to the environmental and sustainability benefits of using our Durox and Toplite aircrete blocks.
Technical Services
Topblock offers a comprehensive range of technical advisory services, employing the very latest software systems to assist customers with the selection, specification and application of the product range.
Customer Services
Over the past few months, a great deal of work has been undertaken within Topblock to fundamentally review the whole business across the UK.
Delivery Options/Livery
Products can be supplied with options to cater for most site conditions. All aircrete products (Durox and Toplite) are shrinkwrapped. Shrinkwrapping is an optional extra for aggregate (Hemelite and Topcrete) products.
Building Regulations
Our blocks provide compliant solutions with the building regulations for England, Wales and Scotland, so you can be confident they're a practical, responsible choice. And because building regulations are constantly being updated, so are our products.
Why use Tarmac Topblock
Tarmac Topblock offers a complete range of aircrete, dense and lightweight products. As a UK market leader, you can expect our blocks to meet the most demanding of building requirements.
Why use our products
Tarmac Topblock manufactures the right block for every application. Our block brands - Durox, Toplite, Hemelite and Topcrete - are all leaders in their own sectors. And this means you can get the best solution for every application from one single supplier.
