Professional Underpinning Services Across Essex

Foundation movement can be a serious concern for any property owner. Cracking, settlement, subsidence and changes in ground conditions can all affect the stability of an existing building, but underpinning is not automatically the right solution for every property.

At Steadfast SES,we provide professional underpinning in Essex after assessing the existing building, its foundations and the circumstances affecting the property.

Our approach combines structural engineering knowledge with practical construction experience, allowing us to assess the problem, establish whether underpinning is appropriate and develop a suitable solution for the individual property.

Where underpinning is required, our team carefully designs and carries out the work in accordance with the structural requirements of the project. Building Regulations generally apply to underpinning work, so we consider the design, construction sequence and inspection requirements before work begins.

Whether you're dealing with suspected subsidence, foundation movement, settlement or inadequate existing foundations, we can provide professional advice and practical support from assessment through to completion.

What Is Underpinning?

Underpinning is a method of strengthening or extending the effective depth or capacity of an existing building's foundations.

However, the appropriate solution depends on factors such as:

  • The existing foundation type and depth
  • Ground conditions
  • The extent of structural movement
  • The cause of settlement or instability
  • The property's construction
  • Nearby structures and boundaries
  • Existing drainage and underground services
  • Proposed changes to the building

Therefore, underpinning is not a one-size-fits-all process. The method and construction sequence should be established through appropriate structural assessment and engineering design.

In some situations, alternative measures may be more appropriate than underpinning. Our aim is to understand the underlying problem before recommending a solution.

When Might Underpinning Be Required?

Underpinning may be appropriate where an existing building's foundations no longer provide adequate support or where proposed changes create additional structural requirements.

For example, potential reasons for underpinning can include:

  • Subsidence
  • Foundation movement
  • Inadequate existing foundations
  • Changes in ground conditions
  • Structural movement
  • Sub-standard or damaged drainage
  • Damage by tree roots
  • Additional storeys or increased loading
  • Extensions affecting existing foundations
  • Basement construction
  • Previous foundation problems
  • Localised foundation failure

The presence of cracking alone does not necessarily mean underpinning is required. A suitable assessment can establish the likely cause of the movement before we specify any remedial work.

Underpinning for Subsidence & Foundation Movement

Subsidence and foundation movement are among the issues that can lead to an investigation into underpinning.

For example, signs that may warrant further assessment include:

  • Cracks appearing in walls
  • Cracks becoming wider over time
  • Doors or windows sticking
  • Uneven floors
  • Gaps appearing around windows or doors
  • Distortion to walls
  • Changes to existing cracks
  • Localised settlement

There can be several causes of building movement, including ground conditions, drainage problems, vegetation, changes in moisture levels and issues with existing foundations.

For this reason, diagnosing the cause is an important part of determining the appropriate remedial approach.

If required, we can work alongside structural engineers and other specialists to establish the nature of the problem and develop an appropriate solution.

Our Underpinning Services

Steadfast SES can provide support for a range of underpinning and foundation-related projects throughout Essex.

Our services can include:

  • Underpinning assessments
  • Underpinning design
  • Traditional underpinning
  • Localised foundation strengthening
  • Foundation repairs
  • Subsidence-related underpinning
  • Foundation stabilisation
  • Underpinning for extensions
  • Underpinning for additional loads
  • Basement-related underpinning
  • Structural repairs
  • Associated building works

The appropriate underpinning method will depend on the property, ground conditions and structural requirements.

Traditional Underpinning

Traditional underpinning involves strengthening existing foundations through carefully controlled excavation and construction beneath or alongside the existing foundation.

Instead, our team generally completes the work in carefully planned sections rather than exposing the entire length of a foundation at once. This approach helps maintain support to the existing structure while our team constructs the new foundation support.

The project's structural design and site conditions determine the precise sequence, section sizes, depths and materials.

Because excavation around existing foundations can affect building stability, our team should only undertake underpinning using an appropriate engineered methodology and experienced construction methods.

Underpinning for Extensions & Building Alterations

An extension can sometimes introduce additional loads or affect the foundations supporting an existing property.

Where existing foundations are inadequate for a proposed alteration, underpinning may form part of the structural solution.

This can be relevant to:

  • Rear extensions
  • Side extensions
  • Double-storey extensions
  • Additional storeys
  • Basement projects
  • Large structural alterations
  • New foundations close to existing structures

Therefore, we assess the existing foundations before deciding whether underpinning is necessary. Planning Portal guidance also notes that engineers may need to check existing foundation capacity where additional loads are introduced.

Our wider Property Extensions and Structural Engineering services provide natural supporting links for projects where underpinning forms part of a larger building scheme.

Underpinning & Structural Engineering

Underpinning and structural engineering are closely connected.

Before underpinning work begins, we may need to investigate the existing building and foundations, establish the cause of movement and design an appropriate structural solution.

Depending on the project, this may involve:

  • Structural surveys
  • Foundation investigations
  • Trial holes
  • Structural calculations
  • Underpinning design
  • Construction sequencing
  • Temporary works
  • Building Control documentation
  • Site inspections
  • Completion inspections

Planning Portal guidance specifically highlights the importance of structural design and engineer's instructions when undertaking underpinning work.

Furthermore, clients requiring wider engineering support, our Structural Engineers service provides a natural internal link to the associated structural engineering expertise.

Our Underpinning Process

Every underpinning project is different, so we follow a structured approach based on the individual property and the cause of the problem.

Initial Consultation

We discuss the issues affecting your property, review any existing information and establish the next steps for assessment.

Property & Foundation Assessment

Where appropriate, the property and existing foundations are investigated to understand the construction, ground conditions and potential cause of movement.

Structural Design

If underpinning is considered necessary, the appropriate structural solution and construction methodology are developed for the project.

Building Control

Underpinning is generally subject to Building Regulations, so the necessary Building Control requirements need to be considered before work begins.

Underpinning Construction

The underpinning is carried out in accordance with the approved design and construction methodology, with careful attention to sequencing and temporary support where required.

Completion

The completed works are checked to ensure the project has been carried out in accordance with the specified requirements.

Frequently Asked Questions

Does cracking mean my house needs underpinning?

Not necessarily. Cracking can have a number of causes. Therefore, we only consider underpinning once we have properly assessed the cause and extent of the structural movement.

What causes a property to need underpinning?

Potential causes include subsidence, settlement, changes in ground conditions, inadequate foundations, foundation movement and increased structural loads. Therefore, we investigate the underlying cause before selecting a remedial solution.

Is underpinning covered by Building Regulations?

Yes. Underpinning is generally classed as building work and Building Regulations requirements apply. Before work begins, we establish the structural design, construction method and inspection requirements.

How do you know if underpinning is required?

In some cases, we may need to assess the existing property and foundations, including foundation depth and ground conditions. We can then use the findings to determine whether underpinning or another solution is appropriate.

Can you underpin a property as part of an extension?

Yes. In some circumstances, an extension or additional load can require existing foundations to be improved. Therefore, we assess the existing foundation capacity as part of the structural design process.

Can underpinning be carried out without a structural engineer?

Underpinning is specialist structural work, so an appropriately qualified team should design and carry out the work using suitable professional expertise. Planning Portal guidance recommends experienced designers and structural engineers for the design and experienced underpinning contractors for construction.

Can you carry out the associated building work?

Where appropriate, Steadfast SES can provide associated structural alterations and construction work, allowing clients to coordinate different stages of their project through one experienced team.
