<p>A substratum (14) for a golf course green (10) comprises a base (12) of natural soil for supporting the substratum (14) thereon, a first layer of moisture absorbent ceramic (16) spread on top of the natural soil, and a first layer of sand (18) spread on top of the first layer of the ceramic (16) for growing the grass plants (40). A second layer of moisture absorbent ceramic (20) is spread on top of the first layer of the sand (18) and a second layer of sand (22) is spread on top of the second layer of the moisture absorbent ceramic (20). The substratum (14) further comprises a drainage system including a bulkhead (30) formed of the ceramic disposed between the first layer of the moisture absorbent ceramic (16) and the second layer of the moisture absorbent ceramic (20). A valve (36) may be provided adjacent to the first layer of ceramic (16) to control fluid or air flow thereto or therefrom. A method of constructing a substratum (14) comprises the steps of preparing a base (12) for supporting the substratum (14) thereon, spreading a first layer of moisture absorbent ceramic (16) on top of the base (12), and spreading a first layer of sand (18) on top of the first layer of the moisture absorbent ceramic (16). The method further comprises spreading a second layer of moisture absorbent ceramic (20) on top of the first layer of the sand (18), spreading a second layer of the sand (22) on top of the second layer of the moisture absorbent ceramic (20), and installing a bulkhead (30) formed from the moisture absorbent ceramic intermediate the first layer of moisture absorbent ceramic (16) and the second layer of moisture absorbent ceramic (20).</p> |
