choosing a liner for your pond

hi all,
         for some time now we have been asked by customers [how do i choose a pond liner]so i
have decided to turn the next issues of the blog into a help page for the installation of pond liners
in a pond,what i hope to do is separate fact from fiction and give you the logic behind your
choice of pond liner,
  pond liners can be as simple as a pvc  liner, butyl rubber liner,render and g4 or fibreglass,and
it is a personal choice as to which you choose,
the myth with pvc liners is that they will crack after a couple of yrs but the reality is the modern
pvc liner is uv stabilised and come with 15/20 yr or in the case of ours a lifetime written guarantee
so installing one is not the risk you are led to believe,and can give years of use providing it is
installed correctly,rubber liners actually have a shorter life span than pvc despite being much more
expensive to purchase,
G4 is a brand of plastic paint that we have used for years and is an alternative to fibreglass but much
cheaper to use,
fibreglass is classed as the ultimate finish,but the reality  is it  depends on the installation and is also the most expensive of all the options,but can be unreliable if installed badly,
tomorrow i will explain the  pros and cons of each one,
regards paul
