Depending on the location and specifications, an example of how we construct the foundations is by using our bespoke galvanised steel frame system. This system allows a strong, stable permanent foundation which is installed without the need for us to use heavy machinery, this minimises the damage to your garden.
Our design team will calculate and design the system suitable for the loading of the building and the ground conditions. The frame legs are lowered in to bored ground holes, these are filled with a specific concrete mix to form support pillars. The pillar design uses a combination of ballast, surface area and friction to provide a stable and secure platform for the sub floor to be attached securely using Evoshield fixings which protect against any corrosion within the steel base.
Damage and impact to the surrounding area is minimal, allowing the garden to recover very quickly.
Our galvanised steel frames have a life expectancy for 100 years +
The steel base is covered with a damp proof membrane, and then fitted with a subfloor created from 100mm thick Structural Insulated Panels (SIPS) which are fixed in the steel base using specialised fixings.
The SIP floor provides a strong, stable and highly insulated sub floor which is then finished with a P5 chipboard floor board.
When combined with a finished floor covering the floor will achieve a U Value of 0.25, which meets the requirements of building regulations 2013 (2016 Amendments)
