| Fastfoot®
is perfect for forming footings over rocky ground.
As the fabric adapts perfectly with the
uneven ground, blasting and excavator costs can be reduced
dramatically. Click on each picture for a larger image.
The 2x4s screed boards are supported with with steel stakes
drilled into the rock, and Fastfoot® fabric is stapled
between the screed boards. |

The location is the highest point of a
residential development above the town of
Squamish, note far from the spectacular Whistler
Blackcomb skiing area.

Installing Steel Stakes
The footings are laid out on the rock, and using a spray can
of paint, the steel stake locations are marked. An electric
hammer drill with a 7/8” bit are used to drill the stake
holes. Each hole takes about 2 minutes to drill (in
granite), with 100 holes taking 3 hours. |

The contractor is blasting
the high spots in order to place the
building correctly. The use of Fastfoot® allows
the rock work to be much rougher than with
lumber formed footings as the fabric easily
adapts to the uneven rock.
|
|
The steel stakes are placed
into the holes, and the 2x4 screed boards screwed to the
metal stakes at the correct height. Set the 2x4s at the
minimum grade to clear the rocks, as footing thickness is
not typically a requirement when forming on rock.
If the holes in the metal stakes are not located at the
correct height, use a 3/4" conduit strap. Click here for

Drilling & installing
steel stakes, 2x4s
The contractor has used conduit straps to attach
the steel stakes to the 2x4 screed boards at the
correct height. Fastfoot® will easily fill in
the gaps by the steps, saving valuable lumber
and time for the contractor

Installing Fastfoot® Fabric
Fastfoot® is pulled between the screed boards, and stapled
in position using a hammer tacker with 3/8" staples. Special
adjustment lines on the fabric ensure adequate fabric is
allowed for deeper footings.

The fabric is perfect for forming to the
uneven rocky grade. Lumber and labor costs are
reduced dramatically.

| Placing
Concrete Concrete was placed
using a concrete pump. Stripping time was minimal as the
concrete didn't touch the lumber or stakes. Stakes were
easily removed because concrete did not seep into the
drilled holes. |

was finished flush with the screed boards.
