Plastic sheet piling are extruded lengths of structural PVC, and in common with steel sheet piling they are used primarily to retain ground or exclude water.   Plastic sheet piling is extremely long lasting, very light to handle and in most applications provides an extremely aesthetic solution for retaining walls, landscaping features, water control applications, erosion control and environmental applications such as ditch locking for peat restoration, or management of flood plains for example the farming in floodplains project.

Applications are not exclusively riparian, we have had a great deal of success in land based retaining structures, THE Plastic Piling Company having the first and only plastic sheet piling system used on both the M1 and M6 motorways.

Quite topical now is the use of plastic sheet piling for flood management and flood prevention.  THE Plastic Piling Company products has been used for reinforcement of levees and embankments, control structures, elevation of flood walls, emergency repair of flood wall defences not to mention channel lining for efficient drainage.  More frequently our plastic piling products are used by residential customers to provide flood defences and flood barriers next to rivers and neighbouring elevated properties.

THE Plastic Piling Company are the first to offer plastic piling with its own in-built water seal! This new feature has been built in to their biggest selling MultiLock Product.

THE Plastic Piling Company is the leading authority on plastic sheet piling; particularly with regard to how these product are installed.  In conjunction with our sister Company, we can provide the very latest plastic sheet piling and pile driving equipment, such as excavator mounted vibrators, EMS mini powerpack vibrators, the Movax Lite ML15 side grip piling vibrator, and plastic piling mandrels.

We are constant innovators, combining the most advanced plastic sheet piling from world leading producers, with our own invention and design of piling equipment.  We have proven time and time again that we have the best products, and this is only possible through our constant innovation.

THE Plastic Piling Company were the first to introduce plastic sheet pile designs that did not copy traditional steel designs; these advanced sheet piling designs provide better performance in terms of installation and use.  These unique designs carry forward sheet pile design, beyond that of what can be accomplished with steel.

Offering plastic piling that is strong and rigid enough to be driven, is only part of the solution. One must also provide innovative methods and equipment to install these sheet piles. THE Plastic Piling Company are the UK agents for the innovative EMS Series vibrators.

Our focus has always been based around the concept that if it cannot be driven it is not a sheet pile, no matter how much it looks like one!

Check out our website on www.plasticpiling.co.uk and check out our advanced range of plastic sheet piles, including the unique THE Plastic Piling Company System Hybrids.  These hybrids utilise our best selling MultiLock, ProLock and Truline with steel, timber and in the case of truline reinforced concrete

The Advanced Range of Plastic Sheet Piles


The Advanced Range of Plastic Sheet Piles

THE Plastic Piling Company is the exclusive distributor of Advanced Plastic Piling.  Within this range, you will find the universal MultiLock, and the designers choice ProLock and Truline. The design and appearance of Plastic Piling,  has always focused on ensuring the end product looks like a steel pile, rather than having match performance.    This may have been an important feature, since all products were produced this way, but what is clear is that the replication of this shape is detrimental to the product's performance.

THE Plastic Piling Company is the first to listen to market requirements and are extremely pleased that our Advanced range is not only a high performance product, but also looks good, to the extent that many designers are either using these Sheet Piling as a feature of the design, or consider using these products for the first time, as these products are so unobtrusive to the environment. These products are also the most versatile products available.  The range offers a wide variety of strength configurations, with an important feature of easy and rapid installation.

 The Advanced designs, specifically MultiLock, prove that plastic piling can be installed easily and rapidly.These products are more usually installed as part of a hybrid system, i.e.  in conjunction with steel, timber or concrete.  They also have sufficient strength to be driven as a conventional sheet pile on their own.  It is a testament to this range that MultiLock, through its performance and ease of installation, appeals to both professional contractors, as well as  the DIY market.

MultiLock is the No.1 selling plastic pile from the extensive range; it is 500mm wide and features two hexagonal tubes. These tubes provide high levels of rigidity and permit internal reinforcement.  On its own, it is a light duty pile around 1/2 as strong as the Corus L8 / Mabey M7.   However, used with 100mm timber piles, it is comparable to these sections.  When used with steel tubes it becomes more comparable to the M11 Trench Sheet.  The MultiLock has gained a reputation as one of the fastest plastic piles to be installed.   This  is  a fact of its design and high rigidity.  It has been driven in 6m lengths for cut-off walls, and in such applications, a single sheet is strong enough to support the EMV300 vibrator.    Not many plastic piles  are capable of such achievement.    MultiLock, like ProLock and Truline, can also be used as  a hybrid king post structure.  Within such a structure, short lengths of the MultiLock  pile are combined with longer posts  or tubes,  rather than rely on a longer pile and deeper penetration.

ProLock has recently benefitted from an update in its design.   Some photos  illustrate ProLock as a two part system - an open fronted pile and a  closing slat.  New ProLock is completely flat frontaged, and as  such, appeals to applications where higher strength needs to be matched with aesthetics.  Like MultiLock, this  product is 500mm wide, but only works with one internal element, 150mm diameter post or tubes.  ProLock has a generated substantial interest for marinas and inland waterways.  It  provides a cantilever solution with steel tubes.  In an anchored design the full flat frontage enables maximum contact with the whaler for optimum distribution of loads.  Unlike MultiLock, it is more commonly used as a hybrid.

Truline Series 800 is the epitome of advanced designs. This  series  comprises  a new twist upon the use of a U shaped pile. Truline forms a U side to side, rather than front to back, creating a box pile, that is subsequently infilled with gravel and concrete.  Truline consists of a main U element and other modules such as corners and end plates.   It is permissible to fully infill Truline with concrete, when installed via trenching.  It is also permissible to use with timber posts and steel tubes/H sections, so long as the pile is infilled with gravel to ensure load transferability.

THE Z Plastic Piles


THE Z Plastic Piles

Plastic piling is simply sheet piling made from recycled PVC, and as such extends the benefits of plastics, into applications that traditionally use sheet piling; whilst extending the benefits of sheet piling into other applications, where steel sheet piling was considered too heavy engineered, non-environmental, or often simply not cost effective.  PVC provides a good material resistance to both chemical and biological agents, so it is long lasting.   It is also has many other useful properties, it is light weight, spark proof and fire resistant.

Plastic piling has naturally been a success in riparian and coastal applications, such as breakwaters, seawalls, revetments and erosion control.   Typically lending itself to any application that involves water control, such as construction of channel lining's, ditch blocks, dams and weir control structures as PVC is not affected by water; in contrast, in similar situations, without constant maintenance steel rusts and wood rots.

It is proving very popular to use plastic piling in a protective role, as scour protection on bridge abutments or erosion facia.  Sheet piling also requires less ground preparation and space than gabion baskets or crib walls. The largest growth market for plastic sheet piling is flood defences, and this has increased dramatically with the introduction of plastic piling from THE Plastic Piling Company that can be easily driven and driven in longer lengths. Plastic piling is also used in many traditional sheet piling applications, such as retaining walls and in temporary works as shoring sheets.  However the lower strength of PVC does tend to limit its use in cantilever, but it is possible to substitute steel for PVC sheet piling so long as the strength is equivalent.  Where an application requires support never just substitute like for like in terms of similar shapes and dimensions, as for a given strength plastic piling will always be deeper and thicker than an equivalent steel pile.

THE Plastic Piling Company has in addition to the following Z pile range, U piles and our advanced range of plastic piling, information on these alternate designs are on our website www.plasticpiling.co.uk

THE Plastic Piling Company offers a very comprehensive range of Z plastic sheet piles, starting with the economy Z profile, the EcoZ.  This is a light duty product available in two thicknesses and was the first design of plastic sheet piling used in the UK.  It was targeted as a budget product.   From this our range now includes the related, but much improved Ultra Z Piles, these are available in three thicknesses and offer a much stronger ribbed design. We have included within this range the Europile and strictly speaking, it not a Z pile, and it does have a similarity to a U Pile in terms if interlock location and drivability.  Its design is however based upon an improvement of the EcoZ and for that reason it is included within this range.   Z Piles are so called Z’s, because the single piles are shaped roughly like a horizontally stretched Z.  The pile is comprised of two flanges having substantially parallel outer faces and an oblique web connected to the two flanges.   The design of the Z pile, places the interlocks at points furthest away from the neutral axis, this basically is putting more material where it is needed and this has a positive influence on the section modulus, ensures good shear transmission and increases the strength-to-weight ratio.  In steel sheet piling, the Z pile is always driven in alternating pairs creating a U shape. In plastic piling, Z piles are also used in this conventional alternating configuration – often referred to as the Box rib configuration; however a repeated pattern, referred to a Z ribbed configuration is perhaps more common with the budget products.  The logic behind this is that a Z ribbed format is under lower stress and so suited to lighter products and it also provides a greater coverage, reducing the number of sheets need improving economy.  The box configuration provides greater strength as the section depth is greater.   For applications that require very little strength and the greatest economy, a thinner version of the EcoZ has been produced.  This thinner EcoZ, the EcoZ Lite is only suitable for use in a z ribbed format, highlighting an important limitation in Z pile design.   

The greater the depth of the section - the further apart the flanges - the thicker the web needs to be to avoid web crippling or buckling.   While depth of section greatly increases moment of inertia, without an increase in wall thickness, there is an increase in the likelihood of a web crippling (buckling) failure.

There are several indicators that can point toward a products susceptibility to web crippling. As a general comparison tool, the slenderness ratio of the webs of different cross sections can be useful. The slenderness ratio is defined as the height of the web divided by its thickness.

Generally speaking slenderness ratio is a comparison tool and does not generate exact load carrying capacities. The higher the slenderness ratio of a cross section's web is, the more susceptible that particular product is to web crippling.  A good example of this is a comparison between the EcoZ and the Europile.  

The Europile offers an improvement over the EcoZ, its design provides a similar bending moment to the box format of the EcoZ, whilst offering the coverage of the rib format.  Therefore the user does not have to compromised between strength and coverage.  At the same time, the web thickness is the same but the section depth is lower, providing a much more stable sheet, with a lower slenderness ratio.  

This design makes the individual sheet stronger, and this is reflected in how that product installs.   There is a marked improvement in the efficiency that the Europile installs over the EcoZ, primarily due to the greater rigidity of this sheet pile.  
Again if one considers the Ultra Z obtains, whilst it benefits from string interlock and ribs, the 11mm version is clearly a more stable product than the more economical 7mm version. 

THE U Plastic Sheet Piles


THE U Plastic Sheet Piles

THE Plastic Piling Company are extremely pleased to add to our range, an extensive choice of U shaped plastic piles. Plastic U sheet piles interlock more like cold formed trench sheeting, than Larssen sheet piling.  The latter having interlocks upon the neutral axis, plastic piling when in a U profile tends to have interlock on one side of the neutral axis.    In a similar configuration to the new ZU hot rolled steel profiles from Japan.  This providing the structural advantages of Z piles with the drivability of U piles.

In general, U piles install better than Z piles, they are wider and so less prone to twist, a wider sheet also means less interlocks and so less leakage.    

Plastic piling is simply sheet piling made from recycled PVC, and as such extends the benefits of plastics, into applications that traditionally use sheet piling; whilst extending the benefits of sheet piling into other applications, where steel sheet piling was considered too heavy engineered, non-environmental, or often simply not cost effective.  PVC provides a good material resistance to both chemical and biological agents, so it is long lasting.   It is also has many other useful properties, it is light weight, spark proof and fire resistant.

THE Plastic Piling Company range starts with the extremely popular Trench Pile.  This was introduced into the range for our utility contractors, looking for a shoring shield.  The trench pile was ideal as it has a very shallow cross section, narrow width that minimises the size of a trench excavation.  It has very little strength and so must be used with other proprietary equipment.  The range then moves into U shaped piles, in earnest, with a 333 mm width offering and a 460mm width offering.  These products are ideally suited for use with our air powered impact hammers. Currently three products have been brought together under the name Ultra U610, due to their width, but unlike the Ultra Z profiles these differ by more than thickness, they differ by depth.  The U610 products are likely to prove extremely popular in cut-off application since there are far less interlocks per metre than when using Z piles.    The much wider, 610mm width has also been shown to better support the pile driving equipment.  During installation this extra width reduces twist motions, improving driving efficiency.  

With the recent addition of the Greenwall range to our range, we are pleased to expand the U Pile range with a premium 610 wide and 460 wide U pile!  A premium quality product without the premium price tag!
 

Jet Filter Europe


Jet Filter Europe

JET Filters are THE managed weep hole system that is vital to marine and bridge infrastructure today.  The JET Filter relieves the hydrostatic pressures created by rain water as well as tidal surges trapped behind almost any design of control structures:

  • Seawalls
  • Bulkheads
  • Retaining Walls
  • Sheet Piling
  • Bridge Abutments

Any earth retaining structure is an investment and to ensure that your investment reaches and exceeds its design life, consideration to proper drainage behind the piled wall is essential.  The lack of weep holes or alternate drainage can lead to a build up of static and dynamic water pressure, from trapped or perched water behind the wall.   This build up of pressure, can reach a level that exceeds the design loads, and as a result lead to premature wall failure.  Panel seams which have opened up or toe failure of the wall can be an indicator of unrelieved pressure due to clogged or insufficient weep holes.  
The most basic weep hole is simply a drilled hole through the structure, but this, whilst eliminating pressure build up, will lead to soil erosion from the rear of the structure or in the long term become clogged.

Soil erosion can be reduced by using a woven geotextile such as Mirafi® FW300, positioned behind the wall, to sieve fines and silts.   Once installed, these textiles are not easily cleaned or replaced and so despite the nature of the material, they will have a limited life as they eventually clog up.   
The JET Filters is an innovative product range that utilises Mirafi® FW300, but in such a way that it can be easily removed, cleaned and replaced.   The innovation of a replaceable filter cartridge is the key component of the JET Filter design.   The JET Filters are available in 3 diameters, 2½”, (ABS Plastic and ASTM Steel)  4” (Steel) and 6”(Steel). 

The JET Filter System uses the highly rated TenCate Mirafi® FW 300 series. This geotextile maintains long-term flow rates in high gradient and dynamic conditions.  The follow rate measured to ASTM D4491 is 4685 l/min/m², with a long term clogging resistance.
At some point it will inevitable clog and/or deteriorate, so it is essential to have access to enable maintenance.  The JET Filter systems ensures this through a design that incorporates a removable inner filter cartridge.  This cartridge can be changed and cleaned if need be—from the front side of the earth retaining structure without removing material behind the wall. The key component of the flush-mount JET Filter System is the ability to remove the inner filter cartridge from the front face, and as such the weep hole systems can be easily installed on any new or existing earth retaining structure.   

The attention to detail is the real secret to the success of the JET Filter, not only is the design highly innovative, using the high quality Mirafi® FW300 geotextile, but it also uses the latest in fastener technology, from Elco. The 2 ½ units are supplied with the self-drilling Dril-Flex stainless steel fasteners,  and the 4” and 6”units are supplied with Tap-flex fasteners that connect the mounting to the cartridge and Ultracon® masonry fasteners to connect the mounting housing to the wall.   The self drilling is clearly an easier function when working with timber or vinyl piles, and pilot holes are recommended when working with steel and masonry. The Dril-Flex and Tap-Flex fasteners undergoes a dual-hardening process to ensure the optimal combination of ductility and hardness, required for maximum performance.    

UltraCon® fasteners are the optimal solution for concrete, brick or hollow block  and offer a proven history of high performance, providing high shear and tensile strength.   Note, that the UltraCon® is only available for the larger JET Filter, with the Dril-flex used still on the 2 ½ for masonry and concrete applications.
All fasteners provided utilise the highly effective  Stalgard coating, for corrosion resistance.  Specifically designed to help prevent hydrogen-induced brittle failures (heads popping), galvanic corrosion and have high resistance to salt spray.

The Stalgard coating provides exception protection against atmospheric corrosion using an environmentally sound chrome free process that is chip resistant.  The multi-step process that combines an inorganic Zinc-rich based coat with an aluminium-pigmented organic topcoat.  The basecoat provides sacrificial protection of the steel substrate while the thermosetting topcoat creates a durable barrier to corrosion.

Piling


Piling

Benefits of plastic sheet piling, particularly the advanced range, include improved longevity – our sheet piles have replaced steel trench sheeting on numerous contracts, where steel simply did not last long enough. Plastic Piling is truly a permanent solution, one that requires no maintenance.  Recent years have seen the expansion of soft engineering boasting improved aesthetics. Plastic sheet piling provides better aesthetics, but with the benefits of a hard engineered structure.
