1. Solid Floor vs Beam and Block FloorConcrete slabDamp proof courseUnderlayWooden floor / carpetPre-cast concrete beamsLightweight blocksQuestion:Explain two advantages of using a beam and block floor instead of a solid floor.
2. Solid Floor Usually made of solid concrete.Bears down directly onto the ground below. This is what supports it.Solid floors are made up of:Hardcore baseSand binding – evens off the surface of the hardcoreDamp proof courseDamp proof membraneInsulation
3. Solid Floor Advantages of Solid floors:Provides a strong foundationKeeps heat in buildingDis-advantages of Solid floors:Cannot be constructed in bad weatherCan be expensivePreparation work may have to be done first before floor is laidTakes a number of weeks for concrete to set completely
4. Beam and Block Floor Made using suspended pre-cast concrete beams and blocks.The beams span between the supporting walls.Beam and block floors are made up of:Pre-cast concrete beamsLight weight block as an infill Pre-cast concrete beamsLightweight blocks
5. Advantages of beam and block floors:Can be laid in bad weatherQuick method of constructionLess expensivePuts less load on the foundationDis-advantages of beam and block floors:Not as strong as a solid floorSupport less of a loadAirbrick needs to be put in to ventilate the space belowBeam and Block Floor

7. Damp proof course (dpc)Stops moisture coming through the walls of the foundationDamp proof course overlaps as it is laid and prevents moisture passing through
