Does a Glass or Polycarbonate Veranda require foundations?

Any glass veranda or aluminium pergola requires a solid base to anchor the support posts/legs to the ground and prevent any movement during high winds. The majority of weight for a wall mounted leaning glass veranda will be supported on the front posts and these need to be totally solid in their fixing points with no movement at all. The supporting posts are either concreted into the ground directly or secured to a concrete base at each point where a support post is required. They should never be screwed into tiles, screeds or light weight substrates. Weight and proper support is essential.

For any self supporting system the ground anchorage is critical without a supporting wall to support and more exposure to wind too.

For lighter weight polycarbonate verandas you can often install using pre cast concrete blocks or pads, which are positioned into the ground after digging a hole or placed under the appropriate slab on your patio to provide the anchor weight and fixing points for the post brackets.

For heavier and larger systems we would recommend larger concrete bases or foundations at the exact positions for the posts and these can be retro installed underneath patios or grass as required.
