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.
