    At these prices the cost of using a protective geotextile underlay as a barrier against stones,roots,shale,wildlife, etc is incredibly cheap compared to the cost,time and effort of having to drain,uplift paving or liner in order to carry out repairs to a hole in a liner where an alternative material has failed.

    Remember, every few years you may have to enter the pond to  carry out maintenance  i.e clean debri or clear overgrown plants - a long lasting protective barrier is therefore essential as it helps “cushion” ones body weight against the possibility of a stone to be pushed through the liner, from beneath.

    All our pond liners carry the appropriate guarantee against any latent manufacturing defects, IRRESPECTIVE of what protective underlay you decide to use i.e underlay,geotextile or carpet etc.

    Carpet or carpet underlay is widely used as a cheap or free alternative to underlay,whilst these materials offer good protection, it is sometimes is only be short term solution as ground-damp could rot most carpets leaving the liner exposed to sharp stones and other abrasive materials.Additionally they are not designed to curb root damage etc.

    Sand is also widely used as a protective barrier,although do not offer any protection against root damage.Kindly ensure that the layer of sand is fairly thick, as the ground will “absorb” some sand over time - also we would recommend an alternative protective material be applied on banks as sand tends to dry out and gather at the bottom of the pond leaving the liner exposed. 

    Note:   Carriage surcharge on all full rolls

    FLP Erocell Ground & Slope Reinforcement & Erosion Control

     Steep slopes, river banks, ditches, spillways and other exposed areas are often prone to damage caused by erosion due to wind or water. FLP Erocell can help to prevent erosion by confining soils and aggregates to within the cell structure.Varying degrees of protection can be afforded by selecting alternative in-fill materials. Seeded topsoil provides protection for less exposed areas. Protection may be increased by introducing vegetation such as small shrubs.For greater protection, a granular in-fill can be used in certain circumstances. Appropiate in-fills can also be chosen to give a desired surface appearance.The standard FLP Cellular System for erosion protection, FLP Erocell, is normally suitable for use on slopes with an incline of up to 45 degrees (1:1 slopes). If the slope angle is greater than 45 degrees, additional considerations need to be given to the design of the cellular system and the standard FLP EROCELL may not be suitable. In these instances please contact us for further assessment. TYPE Incl.

Each site is unique and particular precautions for ensuring a successful installation may differ from site to site.When planning installation, attention should be given to ensuring that all equipment and tools required for installation are available. In addition, sufficient personnel (with the necessary skills) should be employed on the installation work. Adequate precautions should also be taken to ensure the safety of personnel. Some of the other matters to consider when planning installation include:• Desired shapes and sizes of the cells• Methods for compacting the slope surface (during surface preparation)• Methods for fixing FLP EROCELL to the installation surface• Anchoring details, to prevent excessive down-slope movement of FLP EROCELL• Methods for filling the cells• Methods for compacting the in-fill material into the cells, if required.This list is by no means exhaustive and the designer should include all other necessary considerations. If planned correctly, the installation of FLP EROCELL should be a trouble-free experience.(b) Site Preparation Geocells perform better when installed on even,well-prepared surfaces. Prior to installing FLP EROCELL, it is advised that the slope surface is made level and even. Any sharp objects and stones that are much larger than (or significantly different in shape and angularity from) the intended fill material (i.e material to be placed in the cells) should be removed. If necessary, to achieve a level surface, compaction of the slope surface should be undertaken. If required, a suitable geotextile may be used as a separator between the geocell and the slope surface.

    The Big Pond Dip 2009

    Flexible Lining Products Ltd are proud to become a founding member and supporter of The Big Pond Dip 2009 run by Pond Conservation the national charity dedicated to creating and protecting ponds and the wildlife they support

    Everyone knows that one of the best things you can do for wildlife in the garden is to put in a pond. But amazingly nobody really knows what you need to do to make a great wildlife garden pond. What’s the best size and depth? How important is really clean water? What should the edges be like? Is there enough shallow water? There are lots of myths about making ponds in garden - now we want to try to get to the real truth. By taking part in the Big Pond Dip, you are helping Pond Conservation to find out what is living in garden and school ponds, to start answering some of these questions. The information you gather will tell us how good garden ponds are for wildlife. It will also help us to tell what types of pond support the most animal life. We will use this information to give advice about how to make garden ponds even better for wildlife

    FLP Builder Pack

    HOW TO US FLP BUILDER - FOR SEPERATION

    1. Selecting the aggregate
    This can comprise crushed stone, chippings, pebbles, gravel etc – containing a mix of angular large to small materials which can be well compacted to provide a stable surface.

    The maximum stone size should not exceed a third of the compacted depth, thus avoiding point loading onto the FLP Builder.  Don’t forget single-size rounded stone will not compact but move around under traffic and be displaced. 

    2. Depth of aggregate and sand required
    You will need about 15 to 23 cm (6 to 9”) of compacted aggregate to support a surface for light vehicles; while for pedestrian use, a compacted aggregate depth of 10 to 15cm (4 to 6”) should be enough.Depth of sand bedding layer under paved areas should be about 4 to 5 cm (1.5 to 2”). 

    3. How to prepare the ground
    First clear the area of any large stones or other objects which would damage the FLP Builder during installation.  Level the area by removing any undulations and fill any ruts.
    Grass can be left undisturbed but treat any persistent weeds such as thistles and docks with a strong, lasting weedkiller, such as sodium chlorate.

    4. Laying the FLP Builder
    Keep the FLP Builder wrapped against exposure to sunlight until you use it; then lay the FLP Builder directly on top of the levelled ground, weighting the edges if windy. 

    5. Cutting and joining
    You can easily cut FLP Builder to shape with a sharp knife, and you can span any required area by overlapping FLP Builder by 30 cm (12”). 

    6. Putting down the aggregate
    FLP Builder is very strong, and will not be damaged by laying and compacting the aggregate provided you go about this sensibly.  Dump the aggregate and push it forward onto the FLP Builder to the required depth allowing for compaction.  Try to avoid running machinery over the FLP Builder until it is covered with the required depth of material.  Do not traffic the area until the stone has been adequately compacted.  Just simple, sensible precautions.
     
    7. Compacting the aggregate
    Compaction should be thorough enough to provide a solid, stable surface.  Equipment selection will be dependant on the area being treated and the depth of the aggregate being laid. 
    For Drainage:
    You can use graded or single-size clean stone as fill material with FLP Builder. 

    1.After you have dug your drainage trench;  spread FLP Builder over it, and weight it down temporarily if necessary. 

    2.Then gradually tip the first layer of fill onto the FLP Builder so that the fabric will line the trench.  Do this carefully to avoid tearing the FLP Builder. 

    3.Now fill the trench almost to the top with aggregate, and wrap the FLP Builder over it  - without leaving a double thickness on top.  
    If this is a ground-water drain, you can add topsoil to the level of the surrounds and seed with grass. 
    If the drain has to cope with surface water as well as ground water cover the FLP Builder with at least 150 mm of pea gravel – which should stay exposed, and will need occasional maintenance. 

    4.FLP Builder will achieve maximum permeability only after several days in its wet environment.  Some types of soil are particularly difficult to filter – so do obtain specialist advice if you have doubts about your site. 

    Important Note:
    The manner in which FLP Builder is installed, the aggregate used and the ground conditions involved can all affect the performance of FLP Builder and the success of your particular project. 

    If you are not experienced in carrying out the projects of the type listed in this information, you should seek advice from someone appropriately qualified.  This information is a general guide only and therefore cannot cover all aspects involved.

    Pond Liner Installation Guideline - Basic Tips

    POND PLANNING AND CONSTRUCTION DETAILS - Basic tips
    The installation of any pond liner should be a fairly straightforward procedure provided these simple rules are followed:


     Planning:
    This is the most important part of pond building and one that can save a lot of  time, effort and expense, so don’t rush it.
    Decide where the pond is to be sited, ideally a level site that receives at least half-a-days sunlight and is not crossed by buried pipes or cables. Also check the availability of electricity and the cost of running pumps, lights etc.
    The only limit to the size of the liner is how much you can afford. The use of a length of rope or garden hose laid out in the proposed shape of your pond should help you decide what is right for your site.
    The depth of the pond should be a minimum of 18” and generally speaking the deeper, the better as this helps maintain a more stable temperature and avoids complete freezing in winter.
     

    Excavation:

    When digging the pond try to ensure a slope of 15 degrees (3” in for every 9” down) on all sides and incorporate shelves at different depths to accommodate the needs of various aquatic plants.
    Make sure the top of the pond is level, that all sharp objects are removed and that there are no roots that may grow and penetrate the liner.  It is a good idea to line the pond with FLP pond liner underlay (available from your retailer) as an added precaution against damage to the liner.
     

    Liner Installation: Now that the excavation is finished the liner can be draped evenly over the hole and allowed to settle into the contours of the pond, keeping an even overlap on all sides.
     The next step is to push the liner roughly into place and check that there is sufficient overlap on all sides at the top of the pond.
     

    Now begin to fill the pond and as the weight of water pushes the liner into the pond, ease out any small wrinkles and neatly pleat any larger folds. When the pond is full, leave for at least 48 hours before finishing around the top edges (this is to ensure that the liner has not been damaged during installation). 

    The pond may now be finished off in the manner chosen.  A few of the more popular methods of edging have been illustrated below, but if cement is used, any that will come into contact with the water must be neutralised with an appropriate sealant. (Ask your aquatic dealer for the information). Ensure that paving slabs overlay the pond by at least 2” to hide and protect the edge of the liner. 

    General:Always keep the water level right up to the top. This will require topping up in the summer as evaporation can reduce levels by several inches in a very short time. 

    A liner that is exposed to the elements will have a shorter life and be more prone to mechanical damage. Take care when cleaning the pond, or retrieving objects that have dropped into it, that you avoid puncturing the liner by the use of sharp implements (garden fork, rakes, sticks etc).
     

    Finishing:

    Here a firm edge has been made behind the liner at the top to give a firm, level edge for the paving slab. Make sure any gaps between the bricks are packed with sand. This method will hide the top of the liner, but make sure that the bricks used are suitable for the purpose. All mortar must be sealed. 

    To achieve a gravel ‘beach’ type area, a small ridge should be made below the water level to stop the gravel from rolling to the bottom of the pond. This system is ideal for wildlife ponds giving easy entry and exit to the water, while protecting the liner from damage. Again a layer of FLP pond liner underlay between the gravel and liner is required. A rockery that goes right into the water can be achieved by this method.  There must be adequate protection under the rock to avoid damage to the liner, a layer of FLP protective underlay between rocks and liner is recommended

    Pond Liner Selection - Confused ?

    There are a multitude of pond lining materials currently available on the UK market which include Butyl Rubber, Firestone Pond Liner, PVC, Greenseal Rubber, EPDM,PVC,LDPE AND HDPE. Each offering it’s own unique composition and in some cases, restrictive or limited use dependent upon the type of application required.The correct choice of material and quality is therefore  extremely important from the outset,as the wrong product or inferior quality could prove to be only a short-term,uneconomical and costly solution should a problem arise.

    These days,as with most manufactured products, a material is often “renamed or rebranded” by a distributor or retailer to either promote their own logo / brand or  protect the manufacturing source.   i.e Firestone Pond Liner is manufactured by Firestone Building Products USA,it is also marketed and distributed throughout the UK under the Aqualast and Aquacare Rubber brand names amongst others.

    WARNING: To the layman, this can sometimes be a little confusing when seeking a suitable pond liner. Unfortunately there are certain retailers throughout the UK that deem in necessary to misrepresent or mislead the general public as to the actual type of material on offer, at the expense of the customer i.e

    Aqualast Butyl Rubber  - No such material

    Firestone Butyl Rubber - No such material

    Firestone Aqualast Butyl - No such material

    These are 2 completely different material compositions (butyl and EPDM) misrepresented. An EPDM (synthetic rubber) being sold a a Butyl.

    Authentic Butyl Rubber is also known as  Swedish Butyl Rubber or Varnamo Trelleborg Butyl Rubber - the appearance of the material has a slightly “embossed” or “textured” surface. If you have recently purchased a Swedish Butyl Rubber material which is “smooth” in appearance - note this IS NOT Butyl Rubber !

    Aqualast Rubber / Aquacare Rubber or Firestone Pond Liner - this product has a totally smooth surface appearance also the material composition is an EPDM (synthetic rubber NOT butyl). Firestone Rubber Pond Liner is a truely exceptional high quality material - but do not be misled that you are purchasing Butyl Rubber but are actually purchasing a (synthetic rubber) EPDM material. 

    What clouds the selection process further, are products that are promoted using a similar sounding brand name to Butyl Rubber which IS NOT a Butyl Rubber but an EPDM - to the layman this could be confusing since the material name makes a reference to butyl in it’s name, which is clever marketing ploy - but at the end of the day is still not Swedish Butyl Rubber which the customer ends up thinking they have purchased.

    There are new types of EPDM materials entering the UK market which look and feel exactly like Butyl Rubber   i.e has a slightly “embossed” or “textured” surface. As a general rule of thumb EPDM displays a more “elastic”characteristic than Swedish Butyl Rubber.When purchasing Butyl Rubber ensure that it is proper Swedish Butyl Rubber manufactured by Varnamo / Trelleborg Sweden.

    There are also numerous brands of PVC liners offered, varying in both grade and quality. If possible, it is always best to examine the material prior to purchase as you could end up with a product no better than a dustbin liner or a very shiney material that is both cosmetically displeasing and not easy to work with.

    Tips:   In order to safeguard against the possibility of being sold inferior quality or misrepresented materials we reccomend;

    If not pressed for time - request product samples from a few retailers to compare both the quality and inspect any deviation between the appearance and characteristics of the material on offer.

    If buying direct, request the retailer confirms the exact type of material purchased and if possible the name of the manufacturer.This should be recorded on your receipt.

    Ponds are both time consuming and costly to construct and can prove to be very expensive if the initial material selected was inferior or not designed for the application intended.

    When digging the pond try to ensure a slope of 15 degrees (3” in for every 9” down) on all sides and incorporate shelves at different depths to accommodate the needs of various aquatic plants.
     

    Make sure the top of the pond is level, that all sharp objects are removed and that there are no roots that may grow and penetrate the liner.  It is a good idea to line the pond with FLP pond liner underlay (available from your retailer) as an added precaution against damage to the liner.
     

    Liner Installation:
     

    Now that the excavation is finished the liner can be draped evenly over the hole and allowed to settle into the contours of the pond, keeping an even overlap on all sides.
     

    The next step is to push the liner roughly into place and check that there is sufficient overlap on all sides at the top of the pond.
     

    Now begin to fill the pond and as the weight of water pushes the liner into the pond, ease out any small wrinkles and neatly pleat any larger folds. When the pond is full, leave for at least 48 hours before finishing around the top edges (this is to ensure that the liner has not been damaged during installation).
     

    The pond may now be finished off in the manner chosen.  A few of the more popular methods of edging have been illustrated below, but if cement is used, any that will come into contact with the water must be neutralised with an appropriate sealant. (Ask your aquatic dealer for the information).
     

    Ensure that paving slabs overlay the pond by at least 2” to hide and protect the edge of the liner.
     

    General:
     

    Always keep the water level right up to the top. This will require topping up in the summer as evaporation can reduce levels by several inches in a very short time.
     

    A liner that is exposed to the elements will have a shorter life and be more prone to mechanical damage.
     

    Take care when cleaning the pond, or retrieving objects that have dropped into it, that you avoid puncturing the liner by the use of sharp implements (garden fork, rakes, sticks etc).
     

     

    Finishing:
     

    Here a firm edge has been made behind the liner at the top to give a firm, level edge for the paving slab. Make sure any gaps between the bricks are packed with sand.
     

    This method will hide the top of the liner, but make sure that the bricks used are suitable for the purpose. All mortar must be sealed.
     

    To achieve a gravel ‘beach’ type area, a small ridge should be made below the water level to stop the gravel from rolling to the bottom of the pond. This system is ideal for wildlife ponds giving easy entry and exit to the water, while protecting the liner from damage. Again a layer of FLP pond liner underlay between the gravel and liner is required.
     

    A rockery that goes right into the water can be achieved by this method.  There must be adequate protection under the rock to avoid damage to the liner, a layer of FLP protective underlay between rocks and liner is recommended.
