Cracked Concrete Structural Repairs Surrey and Middlesex

Sometimes things were better in the olden days. In the right circumstances, mass concrete underpinning is one of them. Mass concrete underpinning is a tried-and-tested method that has been proven to ensure homes are structurally sound for many years.

Concrete Underpinning Foundation and Property Structural Repairs

Underpinning is the construction task of improving a building’s structural strength by improving the foundations underneath a property. It is a go-to solution for buildings which have significant structural wear or have been deemed unsafe due to weaknesses in their structure.

There are many different methods of doing this. All of which are suitable for different buildings in different circumstances. Note that underpinning may require consent, especially if your property is located in close proximity to another property which may be impacted by such work.

Excavating Property Foundations and Mass Concrete Underpinning Explained

The most common type of underpinning is the one that has stood the test of time. Mass concrete underpinning is usually left for shallower excavations and carried out by excavating sections of the ground below the building’s foundation. This is not a quick job and requires careful progress continuously monitored in stages to reach the required excavation depth.

Each excavated section is loaded with concrete and left until the moisture and temperature reaches an adequate level. By getting the moisture and temperature at the optimal level, the concrete will become as strong and durable as expected; this is known as curing. Each excavated section is filled with concrete and left to cure before moving onto the next. Once all excavated sections have been filled and cured, the property will be left with a stronger foundation to last for many years.

The Process of Mass Concrete Underpinning by Structural Engineers

The processes involved in mass concrete underpinning are not completely pre set. This is because various obstacles can arise during such a task. An experienced and trained professional will be able to overcome unforeseen issues. Nevertheless, a standard mass concreting underpinning project will look something like:

  • Safely excavating the predetermined areas in stages of digging to depths of 12 cms or less. To do this, a sequence is followed to progressively dig all areas to the required depths.
  • Each excavation is then checked for tree roots, soft spots and a layer of rocks are placed at the bottom (stratum).
  • Concrete is then added to each excavation with time given in between so that the concrete cures.
  • Bases are linked together with the aid of joggle joints and optional cages are used between the bases.
  • If the work was constructed on shrinkable clay, polythene sheeting as an anti-heave precaution.

Listed Buildings and Historical Properties Concrete Repairs

Concrete buildings can suffer from a wide range of structural problems. From cracked concrete slabs to spalling concrete, like any type of brickwork, concrete requires maintenance. In fact, cracks in concrete are particularly common in older properties. If you are restoring a listed building or a period home, you will likely have concrete walls. However, the good news is that cracks in concrete brickwork are usually easy to spot.
Undoubtedly strong, concrete is a great material to use when building a house. Durable, this material will ensure that the structure is long lasting and hard wearing. However, overtime concrete may require work to keep it in good shape.

Here are just a few of the problems a concrete structure may face:

● Initial construction mistakes when forming the concrete mix
● Spalling or cracked concrete due to increased pressure or weight
● Erosion from water

Older buildings with concrete walls are more susceptible to decay and may require restoration and repair work. It’s important to assess concrete structures for potential damage from time to time. If you do notice cracked concrete you should seek professional help to restore and repair the wall before it can cause further structural damage to your property.

Concrete Wall and Brick Stitching in Older Properties

Property concrete repairs are often repaired using a protective anti-carbonation coating. Alternatively re-casting with concrete is done to repair the wall, or mortar can be applied by hand to the issue. The best way to repair damage to concrete is with an epoxy repair mortar. This concrete fix is extremely robust and reinforces the strength of the concrete. It can usually be applied on both external and internal concrete walls, floors and slabs.

From a hairline surface crack to structural damage, you should first identify the severity of the problem to your concrete wall. A surface concrete crack, usually only a few millimeters wide and deep, can easily be repaired. Keep an eye on these small lines in concrete walls in case they get bigger over time. On the other hand, a structural crack, much deeper set into the concrete will require professional help. Failing to fix this issue can lead to a much worse structural problem and may even cause problems with the safety of the property as a whole.

Bowed Walls Lateral Restraint Home Renovation West London

How to Fix a Bowed Wall – House Repair. If you’ve just bought a house or you’re currently renovating a property, you may need to fix a few structural issues with the building before moving onto any cosmetic repairs or restoration work. Subsidence, cracked walls and bowed walls can be a serious problem for a lot of older properties that have not been well-maintained. Bowed walls are a serious concern for UK homeowners and property developers as they can collapse at any time. This is not only dangerous but it could cost thousands of pounds to repair.

Bowed walls can be a result of poor structural design, but it can also be caused by soil pressure. Foundation walls can bulge or bow due to excessive lateral pressure from the soil surrounding a house. The pressure can occur when clay soil expands and contracts as moisture in the ground increases or decreases. If your property has a basement or cellar, the foundation walls can be moved due to the weight and pressure of the soil surrounding them. On the other hand, a masonry wall can bow if lateral restraints haven’t been used to strengthen and secure the wall to the floor joints, ceiling joints or roof structure. Let’s explore some possible causes of masonry bowed walls.

Causes of Bowed Walls:

● Home renovations that increase weight and pressure on walls
● Walls that are built too high and too thin
● Heavy materials used for replacing a roof
● Vibration from roadworks
● Insufficient wall ties

If you notice a bowed wall, or cracks in the walls of your property, contact our team immediately for professional house repair guidance, advice and solutions. Our experts at Structural Repairs can assess your unique situation and explain your bowed wall repair options.

Bowed and Bulging Walls – West London Structural Repairs

A bulging wall can collapse, all of a sudden, which can have huge financial implications, not to mention the risk of serious injury or even death should you or a family member be there when it falls down. If you’re renovating or repairing a house and you notice bowed walls, it’s crucial to act fast and repair the wall. Consult house repair experts, and do not attempt to repair a bowed wall yourself as it can be dangerous and may result in a more expensive fix in the long run.

Many structural repair issues relating to deflection or bowing in walls can be fixed with wall restraints. A lateral restraint can fix a bulging wall. Lateral restraints are fitted from the outside of a property for minimum disturbance. Often lateral restraints can be installed by lifting only a couple of floorboards. They are inserted into the wall using a drill and secured well. This provides additional stabilisation and anchoring of the wall to the floor joints. Ties are installed to prevent the wall from moving further or collapsing.

At Structural Repairs, we are industry experts in construction and house repair. Our team can provide expert insight into bowed wall solutions and how to professionally restore and strengthen a property. If you are concerned about walls that look as though they are bowed or moving, contact our team now.

Spalling Concrete, Water Damage and Moisture Repairs

Spalling concrete is another problem with concrete buildings and walls. This can happen when water penetrates the concrete and causes the surface to pop out or in some cases flake off. Spalling concrete happens due to moisture build up. It can sometimes happen when a builder adds too much water to the concrete mix during construction. To fix spalling concrete, a concrete patch repair can be applied to the problem area.

If you notice a problem in a wall that requires a professional concrete fix, feel free to contact our team today. We have plenty of experience repairing and restoring concrete brickwork in the UK.

Cracked Concrete Property Repairs and Marine Seawall Salt Corrosion

Seawall Repairs to Cracked Concrete London and Brighton

We repair seawalls from London and the Home Counties and Brighton and coastal areas on the South UK Coast. Seawalls are expensive structures to build. Designed to hold back water, they must be strong, durable and well maintained. Seawalls are often built along the coast to protect the base of cliffs from erosion, but they can also be built in-land. Agricultural land and properties can be at risk of flood when built within a close proximity to lakes and rivers. Seawalls help protect homes and land from water damage. Maintaining a seawall, whether it be in-land or along the coast is expensive but vital. Let’s discuss why seawalls become damaged and how they can be professionally repaired.

Water is extremely powerful and destructive. You only have to look at the damage a small flood can cause to a property to understand how it could ruin a seawall. There are several factors at play when it comes to seawall corrosion and they can cause significant damage.

Seawall Water Damage to a Property – Flooding Renovations, Damp Mould

When a wall holding back water becomes damaged or is weakened, flooding is a serious concern. Water damage can cause problems with damp, mold, plumbing and pipes. It can also penetrate the foundations of a property, leaving your home unsafe to live in. If a seawall is damaged, you should consider protecting your home from water damage by moving high-value items off the floor and into watertight containers, as well as investing in sandbags, until the wall is professionally repaired.

Signs that a seawall requires a professional repair:

  • There are noticeable cracks in the seawall and you can see gaps between the slabs in the seawall
  • Chunks of the seawall have already started to break off and wash away
  • The seawall is bowing or leaning to one side
  • Rust is beginning to form along the seawall
  • Salt corrosion – a seawall is constantly exposed to saltwater. Over time this can damage the steel structure of the seawall which in turn can cause the concrete to corrode. When cracks in a seawall develop it can begin to break apart and weaken the whole wall.
  • Storm surges – a storm surge or a tidal surge can put significant pressure on a seawall and increase salt water corrosion. The weight and pressure of the water can also impact the structure of the wall and cause it to break.
  • Bad weather – similar to a storm surge, bad weather can cause damage to an existing seawall. Heavy downpours can cause additional erosion, especially when water levels rise.

If your seawall requires a repair you should contact a professional structural repair expert. Failing to properly maintain it puts a town or area at high risk flood and water damage. Since water damage can cause structural problems with a home, this can be detrimental to a homeowner. These structures usually last between 20 and 30 years, but erosion can reduce this timeframe. The average price to replace a seawall can cost anywhere from £150 to £500 per foot. Maintaining your seawall will help to protect your home and land from flood and increase the lifespan of the wall itself.

Dry Rot, Woodworm and Dry Rot Staines Middlesex and Staines

What is Dry Rot & How Can It Damage Your Property?

Dry rot can cause significant damage to a property in the UK. Triggered by excess moisture and damp in a home, dry rot attacks structural parts of a property that are made from wood. Wood decay is a serious health concern for homeowners as it can weaken a property’s structure making it potentially dangerous to live in the house.
If you’re in the process of restoring or renovating a property that has timber frame walls, dry rot could be an issue for you. In fact older properties in London, Surrey, Middlesex and Berkshire are all prone to wood decay and woodworm. So it’s important to check the timber framework in older houses in these cities for signs of dry rot.

You should also keep a lookout for signs of woodworm too! When a building suffers from an infestation such as wood boring beetles, this can damage the structural timber and lead to expensive repair work. Dry rot may not have been in your initial restoration plans, however if your property is suffering from dry rot or wood decay do not ignore this issue.

Structural Damage from Wood Decay – Property Damage Repairs West London

As we’ve just mentioned, dry rot can cause structural damage to a property. This is not just a costly and inconvenient repair for anyone looking to restore or renovate a property, but it can also cause additional issues.

Wood decay can damage timber frame walls, supporting posts and beams, as well as floor and ceiling joists. Dry rot can also damage roof decking too. Early signs of a dry rot problem include wool-like fungus, excess condensation on wooden panels, darkening of existing cracks in wood and shrinking wooden frames or beams. However, when dry rot has been left untreated, you may notice a musky smell and see fungal growth of wooden beams or on wooden frame work.
