Our BackgroundOur Background

• We have over five years of pin pile driving experience.• We have worked with many local engineers:

– Anthony Wright Charlie Lane Doug Gless– James Imbrie Sam Adettiwar Tom Fowler– Craig Lavielle Don Kramer Michael Elia– John Cunningham and more…

• We have successfully used pin piles for:– Retaining walls– Foundation footings– Hillside stabilization– Landslide remediation– (All of the above usually without any excavation required)

Our ResourcesOur Resources

• We have various pneumatic hammers.– From 55 lbs. To 1,500 lbs.– Hand-held to boom mounted.– Striking energy from 22 ft. lbs. To 1,000 ft. lbs.– Pile diameters up to 6.”

• We have various sized heavy equipment with booms– Small trackhoes for very tight job sites.– Larger booms with long reach.

Pin Pile Wall AdvantagesPin Pile Wall Advantages

• Cost savings compared to excavated wall.• Improves slope stability rather than compromising it.• Decreases possibility of erosion and water siltation

during construction.• Environmentally friendly.• Accessibility - can use a crane or hand-held hammer.• Flexible, not rigid - won’t crack.• Water is not trapped, supplementary drainage not

required.• Can be used where soil is too soft for conventional

concrete footings.• Can be built on tight sites where there is no room for

footings.
