RC Ground Beams in Kent, Surrey and the South East
In the field of construction, the stability of a building relies heavily on strong foundations. An essential component in the world of modern foundations is reinforced concrete (RC) ground beams. RC ground beams are horizontal structural elements that play a critical role in the distribution of the load of the superstructure and transferring it to the foundations. In unsafe or uneconomic environments, pile and beam foundations are often the most suitable choice.
Horner Foundations is a regional specialist in RC ground beams. Trading from our home location of Farnham in Hampshire, we cover the surrounding South East counties of Berkshire, Buckinghamshire, Kent, Surrey and Sussex.
This page will give you a clearer insight into the systems we use but please do not hesitate to contact us if you have any further questions.
Understanding RC Ground Beams
RC ground beams, also known as grade beams or tie beams, are reinforced concrete elements constructed below ground level. They act as connective elements between individual foundation piles or columns. A primary function of beams is to distribute the load of the superstructure evenly to the piles or columns, providing added stability and preventing differential settlement.
Purposes and benefits include load distribution.
RC ground beams work as load-bearing members that transfer the vertical loads from walls, columns and slabs to the foundation system. By effectively distributing the load, these beams help avoid localised settlement and ensure the stability of the entire structure. In addition to supporting vertical loads, RC ground beams will also provide lateral support to the foundation.
They resist the horizontal forces induced by wind, seismic activity and soil pressure to enhance the overall structural integrity of foundations.
In varying soil conditions, differential settlement can occur to cause uneven settling of the structure. RC ground beams are adept at mitigating this issue by creating a unified foundation level, thus minimising settling and potential structural damage. Compared to raft foundations, RC ground beams offer an economical alternative for low- to medium-rise buildings. They reduce the need for excessive excavation and concrete usage.
This leads to helpful cost savings on construction projects.
Ground beams allow for design flexibility in construction and accommodate variations in column positions – ideal for irregular building layouts.
RC Ground Beams in Construction
Before beginning the construction process, a site investigation is undertaken to assess the soil conditions, load bearing capacities and groundwater levels. This information helps our structural engineers to determine the appropriate dimensions and reinforcement requirements for the ground beams.
Trenches are excavated in correspondence with the contract drawings.
Formwork is then erected to shape the ground beams. Steel reinforcement is placed within the formwork, incorporating the pile reinforcement into the beams. Reinforcement is designed to handle the anticipated load and to provide adequate support.
Once the formwork and reinforcement are in place, concrete is poured into the trench. Concrete of a specified mix achieves the required strength and durability. After pouring the concrete, the beams are left to cure. This ensures the desired strength and minimises cracking.
Horner Foundations uses RC ground beams on construction projects in the Berkshire, Buckinghamshire, Hampshire, Kent, Surrey and Sussex areas, and we have a skilled team of piling contractors and structural engineers with more than 30 years of collective trade and industry experience.
We look forward to helping you both now and into the future.
