The construction of cricket squares is a much talked about topic
in the field of cricket Curatorship and turf managers in general.
The amount of different soils and construction methods available
is enormous and it should be understood that not one method works
for everyone, and not one method works everywhere.
There have been some bizarre methods used to construct cricket
wickets throughout the world, although on face value these methods
were questionable to say the least; however they worked out to
be very successful and produced wickets that played well producing
excellent consistency, and still do to this day. On the other
hand there has been some other cricket squares constructed and
followed a more standard specification, and for one reason or
another the project failed and requiring the cricket square to
be rebuilt.
When planning a cricket square construction one should approach
the topic with a very open mind. Consider all possible construction
methods, consider all materials that could possibly be part of
the final make up of the profile, and importantly talk to other
Curators/Groundsman in the area that have successfully constructed
cricket squares and have successfully sustained them over a long
period of time, this in itself can be a powerful tool in making
the right decision in what method will be used to construct or
re-construct a cricket square.
In relation to the reconstruction of a cricket square, it can
be time consuming, costly, and inconvenient. Before actually deciding
if a cricket square does in fact require a reconstruction all
aspects should be looked at in relation to the maintenance prior
to deciding on a full reconstruction.
- Consider preparation techniques currently being used and
if they can be modified to improve the performance of the cricket
square
- Look at management of turf & how it can be improved.
- Consider the usage factor & if the current cricket square
is being over used
- Analyze the profile & if it can be improved upon
- Discuss the performance of the cricket square with administrators
& how they believe the performance can be improved
- Compare performance of wickets at the venue to other wickets
in the area and how they measure up.
- Reconstruction is the last option, as a general rule of thumb;
if a cricket square is performing at an acceptable level then
don't change it!
When choosing a construction method along with construction
materials for a new cricket square, clear objectives should
be set for the project. When considering what construction
method will be used firstly look at the key objectives of
the cricket square |

- The weather conditions that will be contested with during
the cricket season, this has a major effect on the decision
making process, the type of clay chosen, the depth of clay,
base material, and grass species.
- The format of the cricket that is going to be played, i.e.
one day, two day, three day, four day, or five day cricket,
this will have an effect on the type of clay chosen and the
depth of clay that is decided upon.
- The amount of cricket that will be played on the cricket
square, this will have an effect on the amount of wickets that
eventually makes up the size of the centre square. Generally
speaking the more matches that will be scheduled in a season,
the bigger the cricket square will need to be.
- The length of the season, this will again have an effect
on the amount of wickets that makes up the cricket square.
- The turf species that will be used on the cricket square,
and whether it needs to be warm or cool season grass.
The construction of a turf cricket square is not too dissimilar
to any other to many other civil constructions - the base work
is all important, and the materials that is placed on the base
will be only as good as the base itself and how solid it has been
constructed. Turf cricket squares have a requirement for the base
to be 100% solid with even cross fall that will mirror the final
levels to move water and provide a solid base for the clay growing
medium to be placed on that will later provide the basis for the
pace and bounce of the prepared pitches. Normally in all other
turf constructions sub-base drainage is a necessity to move irrigation
and rain water away from the site. However, with cricket wickets,
sub - base drainage is not required due to the heavy nature of
the soil that is used - there is a very small amount of water
that actually goes through the wicket profile, hence why sub-surface
drainage is not required, however, drainage around the perimeter
of the cricket square is considered crucial to the 'catch' all
the surface water through surface run off.
The soils used for the construction of cricket squares has a
very specific requirement in that it is required to be able to
be compacted to very high bulk densities to provide good ball
bounce and pace once prepared, but at the same time it must have
the ability to grow grass to a good level. The soil must allow
the grass to produce a good root system, and have the ability
to shrink and swell as it dries and is rewetted through preparation
and maintenance. There is a standard cricket wicket particle distribution
size and physical specification test that the soil must pass before
it is deemed acceptable for use. The aim of the particle size
distribution is to ensure it contains a certain amount of clay,
a certain amount of silt and a certain amount of sand. The aim
of the physical specification test is ensure it performs in a
certain way when placed under the stresses of a prepared pitch,
and importantly has the ability to shrink and swell when placed
preparation conditions of wetting and drying. It is only certain
certified laboratories then test cricket pitch soils for suitability.
During the construction phase of a new or reconstructed cricket
square the placement of suitable soil/clay onto the prepared sub
- base is considered an all important task. The laying of the
suitable material should be done in a similar fashion to laying
a road - the material should be laid in thin layers and compacted
with heavy earth moving equipment. This involves placing the soil
in small but consistent depths and compacted to ensure that there
will be no movement of soils in the future. As each layer is placed
in the cricket square to make up the final depth, it should be
'keyed in' to the previous layer to ensure there is uniformity
through out the completed profile and there is no potential issues
later on during the preparation phase.

The accuracy of the final leveling of the newly constructed or
reconstructed cricket square is absolutely crucial. The surface
falls must be very accurate to ensure that the movement of water
from rainfall and irrigation to the perimeter of the cricket square
is carried out efficiently. The standard sideways fall of a cricket
square ranges between 0.5% - 1%. To achieve maximum efficiency
when conducting the final levels the accurate & proven methods
of the 'peg and rail' system is used. This involves setting up
two metal straight edges 10 feet wide across each wicket, along
the length of the cricket square. The top of the rails need to
be set according to the final levels. i.e. if a wicket has a 1%
sideways fall, one rail is set one percent higher than the other,
making reference to the reference point set at the commencement
of the project. Once these rails are set, the loose clay can be
used to fill the area in between the rails and screened with a
straight edge stretching across the two metal rails until the
final levels are reached and the surface falls are even and consistent.
Final consolidation by roller is done and a final leveling completes
the process.
Selecting a suitable grass for a cricket square is the most simple
task of the project regardless of the location - a turf variety
simply needs to be selected that works, weather it be of a warm
or cool season nature it doesn't matter as long as it is suitable
to that environment, ensuring the selected grass can handle the
local conditions, can handle compaction, and it has good recovery
abilities. It is easily possible to fail the construction or reconstruction
of a cricket square through choosing the wrong grass species.
In summary, it should be remembered that there are many ways
to construct quality cricket squares and no one method works for
everyone. Many conclusions & similarities can be drawn from
different Countries, but there will be always differences. The
simpler things can be kept, the less likely things can go wrong.
It is important to understand your own situation well, understand
your own requirements & needs, work within your boundaries,
and work with good materials. Always remember to do your research,
conduct trials, talk to colleagues, and ensure you have the data
behind you to make sure the next cricket square you construct
is a success. Take in good advice, but end of day you are responsible
for the project, so stick with what works for you.
