installing a box welded liner

hi all,
       today we will discuss the installation of a box welded liner,
box welded liners are more suited to regular shapes but that is not to
say that you have to be square with them,oval or curved ponds can be
constructed by making a template of the top shape,we do this by using
a cheap tarpaulin sheet from a hardware store and cut it to the exact
shape of the pond,this is then used by the manufacturer to produce the
liner,remember to request an overlap,not all suppliers supply a standard
overlap,so always ask,
right we have taken receipt of the liner,we first must open it out and make
sure it is not inside out,you can usually tell because any writing on the
liner is on the underside of the pond so you will not see it when the liner
is installed,
   we then place the liner in the pond taking care to make sure the edge and
corners are properly aligned it is at this point you put some wait on the top
edge of the pond and you can start to fill the liner,as the water enters the pond
start to push out any creases in the bottom of the liner taking care not to pull
the weights holding down the liner into the pond as there is a risk of damage
to the liner,once again the more effort you put into this the better it will look
the advantage with this type of liner you will not have any folds but you may
have small creases in the finished pond but they will be almost invisible in
the finished pond when full of water,as the pond fills keep pulling the edges of
the liner so as to keep the liner slightly stretched so to avoid creases in the
finished article,when full you can install your preferred topping and the pond is
complete just ready to install the filter system which we will cover shortly
