hup! Base is the foundation system designed to make hup! extension projects quicker, simpler, and more predictable. Suitable for most site conditions, it streamlines the build process with reduced groundwork, faster installation, and greater cost certainty - giving you more control from day one.

Unlike traditional foundations, hup! Base can be installed using concrete pads or ground screws, meaning less excavation, less concrete, and far less disruption. It’s a smarter way to build that helps avoid weather delays and keeps your project moving - whatever the season.

With hup! Base, installation is fast, efficient, and far less disruptive than traditional methods. There’s no need for heavy machinery like diggers, and the reduced groundwork means fewer skips - or none at all. The result is a cleaner, tidier site with minimal mess and waste. Everything slots together quickly and accurately, helping you deliver high-quality builds.

The hup! Base is fully compatible with ground screws, offering an even cleaner and more sustainable alternative to traditional concrete foundations. With no need for cement, the installation process is faster, neater, and generates far less waste - perfect for sites where minimal disruption is a priority.

Once ground screws are selected for your project, a local GBGS installer will carry out an initial site assessment to determine the correct number and length of screws based on your site’s lateral and vertical loadings. You’ll then receive a full quote covering the site visit, supply of the ground screws, and installation.

The hup! Base is fully compatible with concrete pads, which can be installed by any groundworks team. This method uses significantly less cement and fewer skips compared to a traditional foundation - making it a cleaner, more efficient choice.

A detailed pad layout plan is provided with your hup! Base, along with a breathable membrane to support ventilation. To meet Building Regulations, concrete pads must be at least 450mm square and positioned so the base sits at least 150mm below the back cill for proper airflow.
