HOW CHEMICAL PILES WORK
Lance is driven
TamPUR 110 injected
TamPUR 110 reacts with pore moisture
And expands approximately 3X
Resin forms rigid matrix in soil
Creating reinforced earth
5
SEQUENCE OF OPERATIONS WALL UNDERPINNING
Foundation drilled and Lance inserted into soil
TamPUR 110 injected Into soil
Made up ground
Resin expansion phase
Lance driven 250mm Deeper into soil
Weak strata
Sequence repeated down to firm base
Firm base substrata
6
CHEMICAL PILING FROM OUTSIDE OF THE BUILDING ONLY
Chemical piles typically 750mm dia at 1000mm
centres
Minimal disruption when carried out From outside
building
The work is rapid and the result guaranteed
