It also explains how to work with structural engineers to diagnose and resolve structural problems.

Many homeowners are unaware of hidden structural problems that significantly impact their property’s value and deter potential buyers. Before putting your house on the market, assessing for structural defects like cracking, rising damp, and faulty roofing that could present serious concerns is crucial. Left unchecked, these issues can lead to exponential building damage and exorbitant structural repair costs down the track.

This article explores the most common structural problems in residential properties, how homeowners can identify them, proven methods for essential structural repairs, and when to consult a building inspector or a structural engineer. We will examine how proactively addressing building defects, water damage, and poor construction makes good financial sense for property investors and prevents more serious problems from developing. Let’s start by looking at some of the most prevalent structural issues that affect houses and buyers’ willingness to purchase.

Common Structural Problems

Cracks in Walls and Floors

Cracks are one of the most prevalent structural issues in residential buildings. Diagonal cracks forming a V-shape can indicate settlement, whereas horizontal cracks suggest expansive soil putting pressure on foundations. Stair-step cracks appearing along mortar joints may signal movement from heave or subsidence. All cracks provide entry points for water, leading to further deterioration like erosion, mould growth and compromised structural integrity. Even hairline cracks should be sealed to prevent water access.

Dampness and Water Damage

Dampness is another widespread structural problem with several causes. Rising damp occurs when moisture from the ground wicks into walls through capillary action. It leaves behind a tide mark and salt crystals, encouraging rot and mould growth and impacting health.

Penetrating dampness happens when water seeps through gaps in the building envelope. Leaking roofs, pipes, poor drainage, flashing issues, or bad site grading can all cause localised damp patches, water stains and erosion. Condensation arises when warm indoor air contacts colder exterior walls and condenses into water, creating an environment for moulds.

Subsidence and Heaving

Subsidence refers to the ground sinking unevenly beneath part of a structure. Nearby excavations, compromised foundations, drainage issues, large trees drying out clay soil, or new construction can all trigger subsidence.

Structural Wall Crack

The sunken section pulls the rest of the building down, resulting in visible symptoms like tilting walls, sagging floors, cracks, and misaligned windows. Heave describes the upward swelling of soil due to moisture changes.

It exerts lifting forces under foundations, potentially fracturing slabs. Both subsidence and heave signal foundational problems.

Rotting Wood and Pest Infestations

Wood rot and infestations seriously compromise timber elements. Wet rot arises from excess moisture, producing spongy sections with cube-shaped fractures. Dry rot forms with inadequate ventilation. Termites and carpenter ants tunnel into wood framing and can devastate structures if left unchecked. Attics with poor ventilation, exterior wall cavities, and subfloors are particularly vulnerable to wood damage.

Deteriorating Masonry

Deteriorating masonry, like crumbling brickwork, stones, or mortar, often results from prolonged water infiltration, poor initial construction, or ground movement stresses over time. Degraded, missing mortar joints allow increased water access, accelerating the deterioration through erosion and cracks. Faulty or aged mortar also permits bricks or stones to shift and settle, damaging the structural integrity.

Inspecting for early signs like minor cracks, small damp patches, or sections of masonry breakdown can help homeowners identify issues before they worsen into major defects requiring expensive repairs. Consulting qualified building inspectors and contractors is essential to determine necessary fixes for any structural problems detected accurately.

Identifying Structural Issues

Visible Signs of Problems

Regularly inspect for clear visible signs like cracks in walls/foundations, sagging floors, doors/windows not closing properly, crumbling or missing masonry, large moisture stains, and gaps or holes in the building envelope. These defects indicate potential structural problems that require further evaluation.

Other Subtle Indicators

Also, watch for subtler clues suggesting issues are developing, such as new small cracks, doors starting to stick, slightly sloping floors, or musty, damp smells. Changes after heavy rain, like new cracks or bowing foundations, are also critical to flag for inspection, as they may signal water damage or destabilised soil.

Areas to Inspect Frequently

Focus inspection on key areas, including roofs, foundations, walls, drainage systems, joints/seams between materials, connections between walls and roofs, chimneys, and ceilings. Check for early structural damage signs like cracked mortar or small stains. Inspecting foundations is especially important, as subsurface problems won’t be visible. Cracks, shifts, and changes after rain provide clues to issues.

Calling in Building Professionals

The goal is to identify structural problems in the earliest stages before repairs become expensive. If defects are spotted, it is crucial to call in building inspectors and structural engineers right away. They have the expertise to diagnose issues and design appropriate repair solutions accurately. Engineers use specialised tools to evaluate problems invisible to homeowners. Early intervention prevents minor issues from escalating into major failures.

Structural Repairs and Solutions

Steel Shoring to Stabilise Foundations

Steel shoring is an effective stabilisation method for foundations or load-bearing elements that have sunk or are unstable. This involves installing heavy steel beams, posts or jacks to shore up and support affected foundations and walls/floors at risk of further movement or collapse.

Shoring prevents continued sinking and damage while more permanent underpinning or full foundation reconstruction solutions are completed. It provides a temporary but vital safeguard.

Underpinning to Strengthen Foundations/h3>

Where foundations have inadequate load-bearing capacity due to settlement, subsidence or other issues, underpinning can permanently strengthen and stabilise them. Techniques involve driving new support pilings or piers deep into the solid ground underneath the existing foundation to provide increased load transfer capacity.

Steel pins are drilled into stable soil layers and then encased in concrete for added reinforcement. Benoto box systems are also used. Underpinning methods stop continued sinking and significantly reinforce compromised foundations.

Crack Stitching to Repair Cracks

Crack stitching bonds the sections back together for cracks caused by shifting, settlement, or expanding reactive clay soils. Expanding resin or epoxy sealant is pressure injected into the crack under force.

The sealant solidifies to rebond cracked elements, preventing further water access and movement. Crack stitching can successfully restore structural integrity.

Paint Moisture Damage

Masonry Repointing to Seal Cracks

Repointing replaces damaged joints in masonry brick, stone and block walls where mortar has degraded. Old mortar is raked out to a depth of at least twice the joint width. New mortar closely matching the original specifications for the appearance, strength, permeability and composition is applied.

Repointing must match traditional techniques to prevent damage. Properly repointed masonry joints seal cracks against water access, stopping erosion and deterioration of the masonry walls and adjacent structural elements.

Drainage Corrections

Improving drainage from foundations is vital to reduce water damage from rising dampness or subsidence. Solutions include regrading soil, adding gravel beds, French drains, sump pumps, or impermeable tanking membranes around foundations. Sealants, proper site grading and addressing pipe leaks also help. Effective drainage prevents costly moisture problems.

Pest Control and Prevention

Timber infestations caused by termites, ants, wood boring beetles and other pests must be controlled as they can severely compromise structural integrity. Treatment involves targeted spraying with pesticides, introducing natural predators, installing physical barriers like mesh screening, replacing damaged timber sections, and applying preventative chemical treatments.

Regular inspections are key to detecting infestations early before major damage occurs. Preventative spraying, keeping timber dry, ample ventilation and sealed entry points help deter pests. Integrated pest management, combining several approaches, provides the best protection.

Working with Structural Engineers

Thorough Evaluation of Problems

Structural engineers are highly trained experts who are essential for thoroughly assessing and fixing complex structural issues. They conduct extensive evaluations using specialised tools and techniques that homeowners lack access to.

These include ground-penetrating radar to identify hidden foundation and soil problems, flood tests to check drainage, precise laser surveys to quantify building movements and shifts, and advanced methods to analyse forces and loads on materials. Structural engineers are able to accurately assess damage, perform in-depth soil and drainage analysis, identify poor construction, and pinpoint the root causes of structural defects and failures.

Custom Repair Design

Engineers create a tailored repair plan addressing all identified issues based on the specific structural flaws uncovered through testing and analysis. For extreme cases, this may involve a range of solutions, from minor crack injections and masonry reinforcement to major underpinning, steel shoring, restumping, drainage overhaul, and full rebuilds.

The engineer focuses on permanent remediation through a holistic plan, not just quick fixes that fail to resolve the underlying problems and defects. Their technical expertise results in the right solutions being matched to the property’s unique needs.

Overseeing Repairs

The structural engineer closely oversees contractors throughout the repair process to ensure work complies with their engineered design and relevant building codes and regulations. They approve appropriate high-quality materials, frequently inspect progress, assess workmanship, identify any emerging issues, advise on problem resolution, and certify repaired sections as safe and structurally sound.

Structural engineers also handle council approvals for building works. Consistent involvement means homeowners can be confident that the repairs meet the highest technical and safety standards.

Benefits of Engineering Expertise

While fees apply, hiring qualified structural engineers provides immense value and often saves significant money in the long term by preventing expensive future structural problems. Their engineering credentials, specialised training, access to advanced technical resources, and extensive building science expertise make them an invaluable ally for permanently resolving structural defects.

Structural Issues

Having an engineer’s expertise protects your investment in the property by ensuring appropriate materials and methods are used for durable repairs. It also minimises the risk of poor workmanship or using the wrong solutions that fail to fix issues properly.
