Ground Beam Construction (Step by Step Guide)

Key Takeaways

Welcome to CEX Construction Engineering. Today we are going to do ground beam construction and why we use it in building foundation. Before we start construction, let's get some explanation of ground beam. In civil engineering, ground beam is a reinforced concrete beam constructed at or below ground level that connects columns or walls to provide support and maintain alignment. It is used to distribute loads evenly, reduce differential settlement and tie structural elements together, especially in cases where the soil has low bearing capacity or when wallsy columns are spaced apart. Let's move to site. Note this foundation depth is 1.2 m to the natural ground level NGL. The earth surrounding the foundation was removed so that everything will be seen clearly.

[Music] [Music] [Music] shuttering. [Music] [Music] [Music] [Music] Inspection of formwork before pouring of concrete. Check through and ensure that the dimension of the beam and column base have been constructed and formed correctly as designed. [Music] [Music] Pouring of grade 20 concrete. Ensure proper vibration.

Laying a foundation wall on the ground beams. [Music] [Music] [Music] [Music] Formwork for starter column. pouring of starter column. [Music] [Music] Formwork removal. [Music] [Music] [Music] Ready for back filling. [Music] Filling with stable aggregate. Sharp sand. Fill it to the brim and compact properly. [Music] As you compact it settles, fill in more and compact again. Placing of damp proof membrane DPM. Add about 50 to 75 mm sand bed before filling with hard core. This prevents hardcore from damaging the DPM. Filling with hard core. [Music] Placing a 50 mm concrete cover. [Music] Fixing a BRC mesh to reinforce the floor slab. [Music] Getting ready for casting of the ground floor slab. Pouring of 150 mm ground floor slab. Ensure proper curing work completed. I upload construction video every week on this channel.
