What we do.
Fortis can provide a fully compliant design and our on-site engineers can assist with local planning control or project engineers for a swift response to any issues faced on site.
Fortis are able to offer solutions for your foundation requirement whether it be a piled Ground Beam or Reinforced Concrete Raft to Traditional Underpinning and Needle Beam supporting systems. Fortis can assist home owners, architects, developers and commercial clients with making an informed decision as to which foundation best suits their needs.
Underpinning is a method of creating support below the ground for an existing structure. This is required when a structure is either sinking or is showing signs of subsidence. These can appear as cracks in the masonry or concrete of the structure. Underpinning can also be used to create a void below an existing building, or to reinforce existing buildings.
Underpinning is accomplished by extending the foundation in depth or in breadth so it either rests on a stronger soil stratum or distributes its load across a greater area. Mini piling methods can also be used in conjunction with underpinning. A small area below the existing foundation or wall base is excavated, then filled with concrete. We dry pack with non-shrink grout, before excavation of the next section is commenced.
