Traditional Methods vs. BASIS
See why BASIS is the superior choice for sloped ground
Level structures on slopes without excavation or retaining walls
Slope requires either excavating to create flat ground, or building retaining walls and adding fill. Both require extensive site work, specialized equipment, and altered drainage patterns before foundation work can begin.
BASIS posts adjust independently from 0 to 600mm to compensate for grade changes. Each post matches the existing ground elevation, creating a level platform without modifying the terrain.
Each post adjusts separately to match ground elevation at that point. Set posts on natural grade, then adjust with a wrench until the frame is level.
Posts sit directly on existing grade with gravel pads underneath. No excavation, cutting, or filling required.
Elevated structure maintains existing water flow patterns. Ground slope continues to drain naturally beneath the building.
If slope settles or erodes over time, adjust posts with a wrench. No excavation or foundation repair required.
If the site proves unsuitable or you need to move the structure, disassemble and reinstall elsewhere. Terrain remains unaltered.

From people who faced similar challenges
We had a 20cm slope and were unsure of the install. BASIS system made it incredibly simple and saved us thousands.
Compensate for slope without excavation. Adjust during installation and again later if ground shifts.
