Cracks on floor finish due to settlement of<br />
filled up soil - note the split between the<br />
floor and the wall skirting<br />
HOME<br />
Cause: Improper consolidation of the<br />
filled up soil.<br />
In normal circumstances, the ground floor<br />
(plinth) level is usually higher than the<br />
external ground level. Hence area bounded<br />
by the plinth walls need to be raised to the<br />
required level. This is accomplished by<br />
filling it up with soil (earth) to the required<br />
level - the normal practice usually adopted<br />
and the cause of the problem.<br />
The Trap:<br />
• To make life easier (or work faster),<br />
workers tend to fill up the space with<br />
soil in large quantities and then ram it.<br />
This leaves voids at lower levels of the<br />
filled up soil, resulting in its settlement<br />
at a later stage (irrespective of whether<br />
the ramming is done manually or<br />
mechanically).<br />
• Areas adjacent to the plinth walls<br />
are relatively inaccessible for proper<br />
ramming, making them vulnerable<br />
areas for future settlement.<br />
• Levelled plots sell at a higher price. Your<br />
site could be a recently filled plot!<br />
