DIY Pond Safety

Pond Safety

The reinforced plastic safety grid called DiamonDeck is strong enough to take a man’s weight. The grid can be used on private ponds, school ponds and nursing home ponds.

The DiamonDeck has a modular design allowing it to be fitted to any sized pond.
Each individual grid and support is measured and cut to the exact contours of your pond giving a perfect fit every time.

Aluminium support beams are used on larger ponds which act as a joist to provide extra support over larger spans. In certain circumstances support cord is passed through the beam and is anchored into the surrounding edge of the pond.

Each individual component has been specifically designed with rounded ends to prevent damage to your fish, liner - and most importantly, your child.

DIY Installation

When you receive your pond safety kit first check that you have the following components:




4) LEGS- give extra support if there is impact


6) LEG STEMS- attach the legs to the beams


8) BEAM BUMPERS - prevents punctuation of pond liner





At the side on the pond, push all of the grids together and ensure they create a surface area greater than the pond surface area

Ensure the water level is at its natural level before beginning to install the Diamondeck product.

Ensure to fit the DiamonDeck in stages as described.

Do not fit all the beams, then the legs, then the grids.


1. Beam Installation

A) Take one ‘beam’ and place a ‘beam bumper’ on one end
B) Hold the ‘beam’ above water approx. 1cm away from the side pond edge & approx. 5 inches away from the top pond edge
C) At the opposite side pond edge, make a cutting mark on the beam mark approx. 1cm before the edge
D) Cut the beam to length using a saw with an aluminium cutting blade
E) Place a ‘beam bumper’ on the newly cut edge
F) Now thread the ’support cord’ through the beam and the two end bumpers.
You now have your first support beam
G) Anchor the ’support cord’ to the surrounding edge of your pond using either a ‘ground stake’ or ‘ceiling hanger rawl plug’ (See Figure 1 below)

TIP- Use ‘Ceiling Hanger Rawl Plugs’ for brickwork/slabbing/concrete surrounds

Use ‘Ground Stakes’ for grass/earth/soft surround

Anchor the support cord to the surrounding edge of your pond

The second beam

H) Take a second ‘beam’ and place a ‘beam bumper’ on one end
I) Hold the ‘beam’ above water approx. 1cm away from the side pond edge & approx 62 cm (grid width) away from the first support ‘beam’
J) Repeat steps C to G above

The intended result is represented in Fig 2 below

2. Support Legs

A) Decide upon the level you wish your DiamonDeck to be
B) Attach a puncture proof ‘foot’ to the bottom of a ‘leg’
C) Rest the ‘foot’ on the bottom of the pond so the top of the ‘leg’ points out of the pond surface
D) Make a cutting mark on ‘leg’ so that when cut it slots underneath the beam and supports your DiamonDeck at your desired level
TIP- When gauging the cutting mark on the ‘leg’ take into consideration that a ‘leg stem’ needs to be pushed in the end of the cut ‘leg’ for attachment to the beam. This may impact the level at which you need to cut the ‘leg’.
E) Cut the ‘leg’ to size
F) Push the ‘leg stem’ onto the cut end of the ‘leg’
G) Slide the ‘leg’ underneath the ‘beam’ and either ’snap- on’ or ’slide’ fit the ‘leg stem’ to the beam
H) Position the ‘legs’ under the beams approx. every 1.5m

3. Grid Placement

A) Starting from the side edge of the pond rest full ‘grids’ (width ways) on the beams (See Figure 2 above)
B) Attach each ‘grid’ to the ‘beams’ using ‘beam clips’ - Use x3 ‘beam clips’ per side of the grid (each grid will therefore have 6 ‘beam clips’)
C) Attach the ‘grids’ together using x2 ‘grid to grid’ clips/grid
D) Repeat steps A-C above until one row of grids are in place

Then repeat all steps so that you have covered the majority of your pond with grids

4. Grid Cutting

You will now need to cut some grids to size/shape to fit the gaps around the edge of the pond

A) Cut ‘grids’ to fit gaps ensuring to leave approx. a 1 cm gap from the edge of the pond
B) Place a ‘grid bumpers’ on all cut edges and affix the ‘grid’ to the ‘beam’ and adjacent ‘grid’ as described above

Check the all grid surfaces are level and there are no gaps. You should have something that looks like this.

Check the all grid surfaces are level and there are no gaps

Pond Safety Ltd designed the Diamondeck pond safety system to the highest standards and to be a strong pond guard that would not give way under a falling mans weight of impact

Strong enough to support a mans weight

    Very interesting even though I don’t have a pond… but I do have friends who would benefit from this solution. Walking on water is possible then!
