- Prepare ground, ensure you have a level area, the OKOBASE raft can be at ground level or below dependent on the height of your timber structure. your building sits on top of the raft.
- Dig pads, we will proceed information on positions of pads, these are very small pads which require minimal digging. on average you will only need to remove 1 cubic meter of earth to install an OKOBASE raft
- Install Hardcore, compact hardcore in layers to build excavated area up to desired level
- Install OKOBASE raft on top of hardcore
- Construct building above
For building control compliant rooms OKOVENTS will need to be installed into the raft, these are pre made and can be added to your order, on average 4 vents are required per OKOBASE raft. The vents simply plug into the raft corners.
Traditional foundation bases are likely to involve substantial earthworks to the foundations. This is likely to be time-consuming and to increase costs. In contrast, installation of an OKOBASE raft may be laid directly onto the existing ground surface, providing it is sufficiently level. This is particularly beneficial where site access may be restricted. For example, a residential garden may only be accessible via the owner’s home, in which case it is desirable to minimise the volume and weight of material to be transported to and from the building location. Also, a reduction in the use of material and transportation will reduce the overall environmental impact of the building installation.
