Thanks to our groundbreaking Gorilla Base technology, you can bid farewell to the inconvenience and time-consuming nature of traditional concrete foundations. The installation process is not only straightforward but also remarkably swift. In fact, most bases can be completed in just a single day. Custom Made for Your Garden Building Gorilla Base isn’t merely a foundation; it’s your steadfast ally in securing the long-term stability and durability of your garden building. Our bespoke timber frame plays a pivotal role in enhancing the lifespan of your structure. By elevating your building and keeping it clear of direct contact with concrete, gravel, or slabs, we eliminate moisture absorption, thereby reducing the risk of rot. This is a critical safeguard, considering that moisture-related damage is a leading cause of building deterioration. Moreover, our innovative design ensures there’s no splash back like with concrete bases, eliminating another common issue that leads to the rotting of the bottom of your building. This base GGS00000-721AA is suitable for buildings up to 72 sq ft / 6.7 sq m.
