Installation Methods for Vinyl Sheet Piles

1) Driving

Driving is the most frequently used method for installing vinyl sheet piles.

Driving involves the mechanical pressing of the piling into the soil with vibration hammers, along previously installed templates.

Light equipment with limited impact force is used in order to protect the piling against damage.

Type of used equipment depends on the type of soil, driving depth and piling strength.

2) Jetting 

Jetting is a method used to install the sheet piling in cohesive or very compact soils.

Under some conditions, the force of vibration hammers is not enough to achieve the required depth.

The reason may be that there are obstacles in the soil or that the soil itself is too hard.

The jetting technology involves creating pressure under the sheet piling foot to loosen and remove the soil under it.

Air or water ejectors with high – or love pressure water pumps are used to loosen the soil.

3) Digging 

Digging is a method used during construction of a piling wall with limited depth, often in stony soils where the driving and jetting technology are not feasible.

The sheet piling is installed in an excavated ditch which is then filled with sand.

The sand bedding should be mechanically or chemically compacted.

Vinyl sheet pile installation

There are a large number of techniques to drive vinyl sheet piles. The system used is largely depending on the circumstances like:

  • Sheet pile length
  • On shore or off shore
  • Soil conditions
  • Water depth
  • Obstructions

In some situations, particularly when short lengths of Plastic Piling are being installed, it can be inserted into the ground by hand using a maul and Pile Cap. This is often the case in peat land areas, where the ground conditions are more favorable. When installing longer lengths, or where the ground conditions are more difficult, a Piling Hammer should be used. Driving the sheet pile directly can be done with a standard pneumatic hammer or a light vibrator with or without a clamp. This system is only suitable for driving at light conditions and to a limited depth.

For heavy conditions and installation from 4 m up to 8 depth it is advisable to used a steel support sheet pile with exactly the same shape as the PVC profile. With the support harder soil can be penetrated and installation is speeded up because the hammer does not have to be disconnected from the steel guiding sheet pile.

Installation of systhetic sheet piling

Vinyl Sheet Piles can be installed in the same way as steel sheet pile. Due to its low weight, installation goes easier and faster. Also the transport and removal is easier.  This results in lower costs for your project. Synthetic sheet piling are ideal for revetment and shore protection. As they do not rust, this is an ideal solution for public areas and embankments.

Installation guidelines

The method of installation depends on:

  • soil composition
  • obstacles
  • height
  • installation depth

Vibrating Plate

The common way to install a sheet pile is with a vibrating plate. Mounted on a crane or excavator, the sheet pile is driving into the ground.

Injection

Injection is an installation method which is used in compact or highly dense soil. The soil is loosened by water injection at the toe of the sheet pile.

Pressing

Sheet pile pressing is noise-less and vibrating-free which makes this installation method suitable for urban areas. This method is depending on the type of sheet piling and the soil composition.

Composite and vinyl sheet piles, bulkheads and sea walls

Our construction and optimum design guarantees high durability and makes possible diverse, very universal application.

Composite vinyl sheet piles can be used as aesthetic and solid sea walls, bulkheads, they secure river banks as well as are a great solution for road construction and in many other situations.

Amongst the advantages of the system the complexity of solutions and the durability of all of the elements are one of the most important. We are also proud of aesthetic look, light weight, incombustibility, as well as safety of our sea walls or bulkheads. Moreover, thanks to high resistance to rust or scratches, our system is superior to traditional solutions made e.g. out of steel.

The combination of modern material, well-thought design and high quality production process results in manufacturing piling which meets even the highest expectations.

Benefits of vinyl and composite piles

There are several reasons to choose vinyl, composite sheet pile. Amongst the most important, the following should be mentioned:

  • low costs – in comparison with traditional solutions, both the initial as well as long-term costs (of e.g. repairs, replacement of damaged elements etc.) are much smaller,
  • resistance – not only with respect to their durability, but also when it comes to UV resistance,
  • simple installation – quick and easy, with the use of simple machinery, allows to limit the time of work as well as the initial costs,
  • high aesthetics – their appearance does not change over time, the color remains the same, thus all of the sea wall, bulkheads etc. remain very aesthetic throughout the years.

The main difference, resulting in diverse application of vinyl sheet piling and its composite alternative, is the maximum height of protective construction created with their use. Since the latter can be installed to create much higher bulkheads, sea walls and other, similar constructions than the former one, it is much more often applied near coast line. Apart from that, with both solutions you get all of the benefits described above.

Why are so many people choosing vinyl sheet piling?

Vinyl sheet piling is quickly becoming the most popular product to use for construction of bulkheads and seawalls. Materials like wood and concrete have been widely used in the past, but the use of these traditional materials is becoming virtually obsolete. With the advent of vinyl sheet piling, homeowners with oceanfront or lakefront property can now rely on the newest manufacturing technology to receive the best product on the market today.

Cost Efficiency

Vinyl is a better value. The real measure of this is not just the comparison of costs for the initial installation; you also need to figure in the costs over the long term. Since vinyl sheet piling lasts much longer than more traditional materials, the cost of repairs and replacement is delayed.

Consistent Appearance

It is well known that wood fades over time. Paint may cover that up, but the paint color will fade as well. There is really not a lot you can do about that except continue to paint in order to keep it looking nice. Vinyl, on the other hand, holds the same beautiful appearance for a very long time.

UV Resistance

Most materials react negatively to the harmful ultraviolet rays of the sun, and it doesn’t take very long for that to start happening. When the time period is stretched out over years, the sun can do some real damage. Vinyl sheet piling is designed to be resistant to this, so the effects of the sun are not as serious or as quick.

Unaffected by Marine Borers

Marine borers are small mollusks or crustaceans that live in the ocean, and their primary source of sustenance is wood. If you use wood for your seawall construction, you will almost immediately have marine borers latching on and drilling into it.

This degrades the integrity and stability of the seawall over time, which defeats the whole purpose of the structure. If a marine borer comes across a seawall constructed with vinyl, it just keeps moving. Vinyl provides no attraction at all for marine borers.

Easy Installation

Vinyl sheet piling provides for an easy installation, particularly compared to wood. Wood is subject to imperfections, warping, and various deformities. This can sometimes cause problems or delays at the time of the installation. Vinyl does not have that problem. Unlike wood, vinyl does not grow in nature; the components of a vinyl seawall are manufactured to some very strict and precise standards.

Installation Methods for Vinyl Sheet Piling

Basically, three methods are used:

Driving

The most commonly used method, in which sheet piles are mechanically pressed into the soil with the use of vibratory hammers along the pre-installed templates. In order to fully protect the piling against damage, light equipment with small impact energy is used. The type of the equipment used is dependent on the type of soil, the depth of the cavity and the durability of the sheet pile. The key to a successful installation in hard, dense surfaces, and in ramming long elements, is the use of special guide bars called mandrels.  Side or front mandrels work best. You can also use multiple mandrels that allow you to mount several pilings at the same time. This is a steel element in the shape reflecting the rammed vinyl sheet pile. Mandrel length must match the length of the rammed PVC elements.

Jetting

It is used for very compact or cohesive soils. Sometimes, in certain conditions, the vibration hammers used for the driving method, do not have enough force to install the vinyl sheet piling on the required depth. It might be caused by a variety of obstacles encountered in the soil, but in some cases the soil itself might be too tough for lightweight equipment. Jetting allows to create pressure directly under the installed sheet piles, which loosens and removes the soil or the obstacles. Special water or air ejectors are applied in this technology.

Digging

This method is usually used, when the depth of the constructed wall is relatively small. Quite often it is chosen for stony ground, which does not allow to employ driving or jetting technology. The plastic piling is installed in a ditch, which is then filled (on both sides) with special bedding layer selected for the project. Mechanical or chemical hardening of the bedding should be performed as well.
