GENERAL GUIDELINES
Equipment
For long piles, three inch holes are pre-drilled near the top of each pile for ease in lifting when using your equipment. These holes may also be used for installation of tiebacks and anchors.
Lifting Piles
For long piles, three inch holes are pre-drilled near the top of each pile for ease in lifting when using your equipment. These holes may also be used for installation of tiebacks and anchors.
Anchoring Systems
Tiebacks with dead man are typically installed for seawalls. Helical anchor systems and earth anchor systems can also be used.
Cantilever designs may also be engineered where there are existing obstructions such as swimming pools and buildings in close proximity and make anchors a difficult and costly consideration.
Cast-in-Place
Piles can be used as a permanent form to fill with concrete (steel rebar is used as needed). Also, sand or gravel may be used to fill the piles for permanent walls. Calculate the fill based upon the exposure less space for top cap material. Fill per foot guide:
800 series: 0.022 cu.yds or 0.030 tons per ft.
1200 series: 0.049 cu.yds or 0.066 tons per ft.
Temporary Walls
Temporary walls can be installed by placing the piles in location and filling with sand or gravel. Once the wall is no longer needed, the piles are easily removed and repositioned.
Capping Options
Concrete, timber, aluminum, composite decking or other materials as engineered and designed may be used.
Filter Systems
Accommodates any filter system or well-point drain as required.
French Drains
Some projects and areas require a French drain to be installed as part of the water drainage system. Your local engineer will specify if needed.
