1. Improved Jacketing Repair System
for Steal H-Beams
3/24/21

2. What is the problem?
• Estimated cost of repairing
deficient bridges in the US is over
$32billion.
• Missouri Department of
Transportation (MoDOT) is
responsible for maintaining
10,400 bridges.
• Missouri has the 4th highest
number of deficient bridges in
the US with more than 3,222
deficient bridges.
• Many of these bridges
constructed using steel H-piles
which by inspection revealed
different degrees of localized
corrosion.

3. How does product/service solve problem?
• Efficient and durable to
restore original axial
capacity
• Easy and accelerated
technique
• Methyl methacrylate
polymer concrete
(MMA-PC) for better
weather resistance

4. What is the market use?
• Repair of steel-H piles used in
infrastructure:
– Bridges
– Docks
– Piers
• “A recent estimate for the nation’s
backlog of bridge repair needs is
$125 billion. We need to increase
spending on bridge rehabilitation
from $14.4 billion annually to
$22.7 billion annually, or by 58%, if
we are to improve the condition.”
– ASCE 2021 Report Card

5. What competition exists?
• PileMedic® - allows construction of a seamless
cylindrical shell around an existing pile or column.
• PILECAP - 100% structural jacket that provides
alternative to driving new piles; can also be
injected with grout or epoxy to fill voids and
damaged area.
• FX-70® Piling Repair –
Epoxies
Conventional concrete
Fiber wraps

6. What is the status of the intellectual property?
Provisional application, 63/047,289: Method
and Apparatus for reinforcing Steel H-Piles,
filed July 2020.

7. What is the stage of development?
• How much testing?
Seven columns under axial
compression
Varied jacket lengths
Adaptable to different
concrete formulations

8. What is needed for further development?
• Fatigue testing
• Testing under eccentric loads
• Testing under seismic loads
