Our
techniques apply when adding new structures:
especially
rock anchor,
microfine cement,
soil nailing,
micropile
installations for
foundation support.
We
specialize in
slope stabilization,
anchors,
permeation grouting,
foundation repair
and support,
grouting,
soil nails,
rock drilling,
micropile installations, and
sinkholes. We
use a
problem-solving approach geotechnical
architecture of buildings, bridges,
water plants, sewage plants, tunnels,
sinkholes,
caisson,
shoring,
underpinning,
agriculture, and
roads
construction. We
are experienced in these applications:
micro piles,
sinkhole repair,
permeation grouting, pressure
grout,
soil nails,
chemical grouting,
micropiles,
compaction grout, and
rock anchors.
Our specialties are
rock anchor,
acrylamide and
compaction grouting,
mini piles,
sinkhole repair,
micropiles,
acrylamide grouting, and
soil nailing.
We will continue to dedicate ourselves to
excellence,
including
insurance mortgage, in our performance, in our
integrity, and in our relationships with our
customers. We will carefully weigh our
decisions, actions, and results to make sure
that we remain the most trusted name in the
geotechnical contracting industry. Please

Drilling Problems
The difficulties encountered in drilling can include cave-ins, groundwater, and utilities.
The following briefly describes some actions which can be taken in these situations.
In the case of cave-ins, the following action or combination thereof may be required:
ITEM
ACTION
1
Placement of a low cement/sand mix and redrilling the area of the cave-in.
2
If permitted by the contract Special Provisions, use of a drilling slurry (refer
to Chapter 9 of this manual).
3
Use of a casing which is pulled when placing concrete.
In the case of groundwater, the following action or combination thereof may be required:
ITEM
ACTION
1
Placement of a low cement/sand mix and redrilling the hole.
2
Drilling to tip elevation, using a pump to remove the water and cleaning
out the bottom of the pile.
3
If permitted by the contract Special Provisions, use of a drilling slurry (refer
to Chapter 9 of this manual).
4
Placement of a casing, again using a pump to remove the water, and
pulling casing during concrete placing (keeping bottom of casing below
the concrete surface).
5
Dewatering the entire area using well points, deep wells, etc. This should be
thoroughly discussed with the Bridge Construction Engineer and the
Engineering Geologist.
6
By contract change order, substitute an alternative type of piling. Again,
this should be discussed with the Project Designer, the Engineering
Geologist, and the Bridge Construction Engineer.
Operations should proceed with caution when drilling near utilities known or thought to be
in close proximity. The Contractor should contact the utility company and have the utility
located. It is also advised that the Contractor pothole and physically locate the utility prior
to drilling. Relocation of the utility may be required. Minor adjustments in pile location
might be feasible in order to avoid conflict. Any proposed revisions to the pile layout should
be discussed with the Project Designer, the Engineering Geologist, and the Bridge Construc-
tion Engineer.
