Abstract
The invention refers to a base structure, particularly for tennis courts, comprising a top layer consisting of a solid microporous plate comprising a mixture from 50% to 98% fine clay and 2% to 50% cement, the thickness of the top layer being of at least 2 cm in the non-compacted state, wherein the solid microporous plate results from chemical reaction by means of water added to said mixture. The invention also provides a tennis court, the surface of which is inclined at least 0.25% as to permit excess water to flow towards the center or one side of the court. A method of building such a court is also described.
Claims20
A base structure, particularly suitable for tennis courts, including a top layer which is a solid monolithic microporous plate comprising a compacted and cured mixture of from 50% to 98% fine clay particles which can pass through a mesh 22, and from 2% to 50% cement, the thickness of said top layer being at least 2 cm before compaction and curing, said solid microporous plate resulting from chemical curing on the addition of water to said mixture after in situ compaction.
A method for building a base structure suitable for tennis courts including a top layer which is a solid microporous plate, said method including the following steps:
- flattening and compacting the ground on which the base structure will be made;
- preparing a dry mixture of 50% to 98% fine clay particles which can pass through a mesh 22, and 2% to 50% cement;
- covering the ground with an at least 2 cm thick layer of the said dry mixture to provide a top layer;
- subjecting said mixture to compacting of from 20% to 40%;
- and
- watering the surface of the court so that the whole top layer is impregnated with water as to cause the dry mixture to form a solid microporous block or plate by chemical curing.
