Measuring Your Dam

Rural and Farm Dam Liner
"The correct dam liner size is essential”

Measuring your Dam for a Dam Liner

Even though many dams can sometimes be large or irregular, fitting your dam with a liner is not too difficult. Apart from site preparation, you will also need to make sure your order enough liner such that it will fit properly. But don't order too much as that makes it more expensive than necessary. This then means you have to measure the dam area properly.

There are only a couple of factors that need to be looked at when working out how much dam liner you will need, but these are quite often are overlooked. When seeking a quote, make sure the following have been factored in:

  • Accurate depth of the dam. It is important that you measure the maximum depth of the dam as accurately as possible. It is our experience that many people tend to guess and over estimate the depth of a dam.
  • The anchor trench. Generally the bigger and deeper the dam, the wider, deeper and further away you will need the anchor trench to be.
  • Width of the dam wall. Larger and deeper dams also require a wider dam wall to properly secure the dam liner.
  • The slope of the dam walls. Generally dam walls are made between a 1:3 and a 1:1 gradient. A 1:3 gradient is the most common as the machinery used to dig out the dam can't usually cope with anything steeper. A steeper dam wall will mean that more dam liner will be needed.
  • The shape of the dam. While a dam liner can be made to almost any shape, it is generally not cost effective as labour rates can be more expensive than material costs.
