Strip foundations spread the load from walls of brick, masonry or concrete to the subsoil. The foundation depth depends on strength of material, foundation loads and breading capacity of the subsoil.  \nFigure 1.1-Strip foundation  \n Detail G01-Strip foundation  \n8 SECTION 1-FOUNDATIONS AND FLOORS  \nIf the subsoil is weak or susceptible to movement the foundation can be taken to a suitable depth where the strata is stronger and able to bear the loads of the proposed structure.  \nThe width of the strip foundation must be adequate that there is room to lay walling material, and also able to spread the loads to a suitable area of subsoil. As a general rule, the projection of the strip each side of the wall should be no greater than the thickness of the concrete.  \nIn other cases, a wide strip foundation may be used to spread the load of the foundation or the strip can be reinforced.  \nStrip foundations are more commonly used in domestic and residential construction, or more low rise construction.  \nFigure 1.2-Deep strip foundation  \nDetail G02-Deep strip foundation  \n9  \nPAD FOUNDATIONS  \nA pad foundation is generally a square of reinforced concrete, that takes the loading from the column above and transfers it to the ground. The column is positioned centrally on the foundation pad, which requires the pad to be sufficiently reinforced to avoid the point loading of the column punching through the foundation.  \nThe column or pier that sits on the pad foundation can be brick, masonry, concrete or steel. Once again the area of the pad is dependent on strength of subsoil, and loading on the foundation material.  \n Detail G03 G04-Simple pad foundation with and without reinforcement  \nGround beams are often used to span between the pads and transfer the load of the infill wall to the pads.  \nPads can sometimes be linked with concrete strip when they are particularly close together, resulting from a frame that has close spacing.  \nFigure 1. 3-Example of a pad foundation with ground beam  \n10 SECTION 1-FOUNDATIONS AND FLOORS  \nDetail G18 B-Raft foundation with toe-concrete frame-alternative detail  \n26 SECTION 1-FOUNDATIONS AND FLOORS  \n3D Detail G18 B-Raft foundation with toe-concrete frame-alternative detail  \n27  \n Detail G28-Beam and block floor-beams parallel to wall, cast in situ concrete downstand  \n42 SECTION 1-FOUNDATIONS AND FLOORS  \n3D Detail G28-Beam and block floor-beams parallel to wall, cast in situ concrete downstand  \n43","cbCaipgfKUNJFwqW","https://ap.wps.com/l/cbCaipgfKUNJFwqW","pdf",3334519,23,"English","# Introduction\n# Foundations & Floors\n## Principles of Foundation Design","[{\"question\":\"What are the main types of foundations discussed in the guide?\",\"answer\":\"The guide identifies four main types: strip foundations, pad foundations, raft foundations, and pile foundations.\"},{\"question\":\"What is the purpose of a strip foundation?\",\"answer\":\"A strip foundation uses a single concrete strip to provide a firm, level base for walls and spreads wall loads from brick, masonry, or concrete to the subsoil.\"},{\"question\":\"How does a pad foundation transfer loads from the structure?\",\"answer\":\"A pad foundation is a reinforced concrete pad that receives loading from the column above and transfers it to the ground.
