sTRIP FOUNDATION CAN BE CONSIDERED UNDER 3 CATEGORIES ;

TRADITIONAL STRIP FOUNDATION

1. THE WIDTH OF A CONCRETE STRIP FOUNDATION DEPENDS ON THE BEARING CAPACITY OF THE SUBSOIL AND THE LOAD ON THE FOUNDATION.
2. THE GREATER THE BEARING CAPACITY OF THE SUBSOIL , THE LESS THE WIDTH OF THE FOUNDATION AND VICE VERSA.
3. THE CONCRETE STRIP WILL GENERALLY BE WIDER THAN THE THICKNESS OF THE WALL

• FOR THE CONVENIENCE OF FILINGS A WIDER TRENCH WITH CONCRETE DUE TO THE WIDTH OF THE EXCAVATION BUCKET;
• FOR THE CONVENIENCE OF LAYING BRICK BELOW GROUND , ALLOWINGS ADEQUATE WORKING SPACE.

4.THE MINIMUM WIDTH OF THE STRIP FOUNDATION IS 450 MM WHICH GIVES A RESONABLEBEARING AREA FOR MOST TWO STOREY HOUSES ON MOST SUBSOIL.

5.THE PRACTICAL MINIMUM DEPTH OF A STRIP FOUNDATION IS USUALLY 450MM TO ALLOW FOR THE REMOVAL OF TOP SOIL AND VARIATIONS IN GROUND LEVEL .

6.THE MINIMUM THICKNESS OF CONCRETE FOR A STRIP FOUNDATION IS GENERALLY 150MM AND THE CONCRETE SHOULD BE AT LEAST AS THICK AS THE PROKECTION OF THE STRIP EACH SIDE OD THE WALL WHERE THE CONCRETE IS NOT REINFOCED .
