PROJECT PROPOSAL
GENERAL OVERVIEW
Lakeshore Drive provides access to an industrial area in a southern part of Coppell. The 40 foot
roadway consists of PCC (Jointed) Concrete Pavement with an integral curb and gutter. Drop
inlets are utilized to transport run-off. Sections of the streets have settled which resulted in
ponding of water and a rough surface. Also, drop inlets have settled which has resulted in poor
drainage and pavement distress. An inspection was made on September 6, 1997 and priority
locations were identified by Mr. Matt Cast.
Uretek USA, Inc. proposes to fill voids, stabilize and lift the concrete pavement to restore
rideability and drainage. Drop inlets will be lifted to restore vertical alignment with the
pavement.

EQUIPMENT. The minimum list of equipment required shall be as listed below and shall not
preclude the use of additional equipment.
A. A pneumatic drill, capable of drilling 1/2 - 5/8 inch diameter holes.
B. A self contained truck mounted pumping unit capable of storing, proportioning, blending,
and injecting the polyurethane formulation under the concrete pavement. The equipment
will be of size and nature to control the rate of rise of the pavement.
C. A laser leveling unit, straight edge or stringling to ensure that the concrete is raised to an
even plane and/or to the required elevation.
CONSTRUCTION METHODS. The 1/2 inch diameter hole shall be drilled in the following
manner.
As a series of holes shall be drilled at six to eight foot intervals throughout the concrete. The
exact location of the holes shall be determined by Uretek USA.
(LIRETEK)-J
The following construction procedures will be used:
A profile of the repair area will be developed to determine the extent to be raised. A series of
1/2 inch diameter holes will be drilled at the necessary locations and intervals. The Uretek 486
polyurethane formulation is then injected under the slab. As the polyurethane chemically reacts
it will expand, exerting the necessary lifting force, and harden to provide the structural strength
required.
The amount of rise shall be controlled by the pumping unit and injection gun.
Uretek USA shall be responsible for any pavement blowouts as well as excessive or uneven
pavement moving which will cause ponding, and shall replace or fix the damaged area to the
satisfaction of the Engineer.
When the injection nozzle is removed from the hole, any excessive polyurethane material shall
be removed from the area and the holes sealed with the polyurethane material or a quickset
concrete patch.
MEASUREMENT. The Uretek 486 polyurethane material shall be paid for by the pound which
will include furnishing, blending, and injecting material.
PAYMENT. The quantity of material to be paid for shall be the quantity actually used, based on
the contract unit price shown on the bid form.
Only those bid items shown on the bid sheet shall be paid for directly. All other labor, tool,
equipment and incidentals necessary for the completion of the project shall not be paid for
directly, but shall be considered incidental to the contract bid items.
