With Southamp<strong>to</strong>n flying<br />

high in the <strong>Championship</strong>,<br />

their free flowing, passing<br />

game requires a good<br />

surface. Charged with<br />

providing that is Grounds<br />

Manager, Andy Gray, and<br />

his team of four<br />

It’s not all been plain<br />

Southamp<strong>to</strong>n Football Club have<br />

been at their ‘new’ home, the St<br />

Mary’s Stadium, for just over ten<br />

years. The name reflects the<br />

club’s his<strong>to</strong>ry; they were formed<br />

in 1885 when at team from St. Mary’s<br />

Young Men’s Association played their<br />

first match on the ‘backfield’ of<br />

Hampshire County Cricket Club.<br />

After over one hundred years at their<br />

former home, the rather quirky ‘The<br />

Dell’, with its odd, almost wedge shaped<br />

stand behind one of the goals, the club’s<br />

move <strong>to</strong> St. Mary’s saw a dip in their<br />

fortunes as they slid down the leagues.<br />

Now, currently riding high in the<br />

<strong>Championship</strong>, a return <strong>to</strong> the <strong>to</strong>p flight<br />

looks on the cards, and the quality of<br />

the playing surface is a contributing<br />

fac<strong>to</strong>r.<br />

Some well known names have graced<br />

the surface at Southamp<strong>to</strong>n, amongst<br />

them Mick Shannon, Kevin Keegan,<br />

Peter Shil<strong>to</strong>n, Alan Shearer, Alan Ball<br />

and Matthew Le Tissier. Tottenham’s<br />

current star, Gareth Bale, played in his<br />

SAINTS...<br />

formative years for the Saints.<br />

Managing the surface is Andy Gray,<br />

one of the youngest Grounds Managers<br />

in the country. He was promoted <strong>to</strong> the<br />

role one year ago after a spell as joint<br />

head groundsman after Dave Roberts<br />

had left the club for Charterhouse<br />

School. Dave and Andy had not been<br />

involved <strong>to</strong>o much with the original<br />

laying of the pitch as they were still<br />

working at The Dell.<br />

By modern standards, it is a relatively<br />

basic design, built over a gravel<br />

raft/carpet with primary drains running<br />

at 3m centres, a 50mm binding layer of<br />

grit sits on <strong>to</strong>p, which was originally<br />

covered with a 200mm depth of 80/20<br />

rootzone. The rootzone was, at the time,<br />

95% sand, 2% silt and 3% clay, and laid<br />

<strong>to</strong>tally flat, i.e. with no crown.<br />

This original pitch specification<br />

brought with it some serious drainage<br />

problems that Dave and Andy had <strong>to</strong> try<br />

and overcome. It <strong>to</strong>ok them a couple of<br />

years <strong>to</strong> find out the exact cause and<br />

begin remedial work. The problem was<br />

that, after heavy rain, the pitch did not<br />

drain effectively, water was being held<br />

in the shallow (200mm) sand profile by<br />

capillary tension. In scientific terms, the<br />

hydraulic drive was not enough <strong>to</strong> push<br />

the water through the shallow profile - a<br />

shallow, perched water table was<br />

preventing any free draining.<br />

Most modern pitch profiles have at<br />

least 300mm depth of rootzone<br />

materials, thereby giving the necessary<br />

hydraulic drive <strong>to</strong> push water through<br />

in<strong>to</strong> the primary drainage system. The<br />

300mm depth enables the pitch <strong>to</strong> build<br />

up enough weight of water <strong>to</strong> help push<br />

it in<strong>to</strong> the drainage layer, thereby<br />

allowing the pitch <strong>to</strong> meet its specified<br />

drainage rates, often designed <strong>to</strong> cope<br />

with 25mm of rain per hour.<br />

The ideal solution would have been <strong>to</strong><br />

reconstruct the pitch. However, for<br />

various reasons, that option was not<br />

taken. So, the only other option was <strong>to</strong><br />

carry on with appropriate aeration<br />

works and then, over time, begin <strong>to</strong><br />

increase the depth of rootzone during
