Concrete Spalling Repairs

Concrete Spalling Repairs

What are the causes of concrete spalling and how do we carry out concrete spalling repairs

 Concrete Spalling is the result of reinforcing steel either being installed too close to the surface of a concrete structure or from the concrete being left uncoated and then being exposed to the British Weather elements.

New concrete is naturally very alkaline. This high alkalinity actually acts to protect steel reinforcing from corrosion. The effect of weathering of bare concrete is that concrete slowly has its alkaline materials washed out of it. In areas of acid rain in highly industrialised countries the process will be accelerated. As this happens the steel will then begin to corrode. When steel rusts it can expand up to 3 times its original size. Reinforced steel is embedded in the concrete but as the steel rusts it eventually forces the concrete to crack, exposing the steel reinforcing and internal concrete to the weather elements. The process repeats itself with the situation continually worsening, hence the name concrete cancer.

Concrete Spalling repairs are carried out by cutting out the delaminated concrete, replacing or cleaning the steel reinforcement, priming the steel plus the surrounding concrete and then repairing with a high grade polymer modified concrete repair mortar to original profile, this will restore the structural integrity to super structure.

 

Ginger staining on concrete is cause for concern

Slight rust stains coming out of an otherwise innocent looking concrete surface are often the first symptom of spalling. Such areas must have concrete spalling repairs carried out immediately.

Protective coatings will prevent the need for concrete spalling repairs and save you money in the long run.

London Structural Repairs frequently complete concrete spalling repairs for  local authorities on local housing schemes, main contractors and private sector.

Concrete Window Sill Repairs

Concrete Window Sill Repairs

Londons Concrete Window Sill Repairs Specialists could save you money and disruption

London Structural Repairs carried out repairs to Concrete Window sill Repairs at two private residential property blocks in Brentwood, Essex.

The property’s Concrete Window sills were suffering from concrete spalling because of deteriorating steel rods in-bedded in the Window sills causing cracking and sections of the window sills to fail.
Our sympathetic cost effective repairs were of no disruption to the residents of the property, the failed concrete Window sills had new reinforcing rods installed and were repaired using specialist mortars then given two coats of anti-carbonation coatings this will insure a long lasting repair without the need for the removal of the windows and installing new Concrete Window sill’s causing disruption and expensive costs to the residents.

Are your Window Sills on your routine maintenance list?

Concrete Window Sill repairs may not seem like an important part of your home’s structure and they are probably far from the top of any ones priority list when it comes to maintaining your property. But they do play a vital role in protecting your home from the weather elements and they can be the first weak point when it comes to letting rain or damp into your property. A cracked, poorly maintained or uneven Window sill can let rainwater drain into your property, meaning stained wallpaper, mould or damaged plaster. All of these can mean ongoing problems and expensive repair jobs.

Why not give us a call no query to small

Your window sills may seem like decorative features but they are actually very simple pieces of engineering design that allow the water to run away freely, like guttering for your windows. The outward fall allows the rain to run off the windowsills and away from the windows and walls, keeping your property dry.
In most cases a stone or concrete Window sill Repairs can be carried out by a specialist and saved, but if it is beyond repair then replacing it will be the only option and you may need to remove the entire window frame to carry this work out and also run the risk of damaging bricks, so make sure you use a specialist contractor with experience in this kind of work.

Make sure you employ a specialist contractor for a hassle free project

Whether you are having your window sills replaced or repaired you will want to check that the finished results will last and keep water away from your window frames and your walls. So do give the job the once-over and make sure that the window sills are set at an angle running away from the property. You can see how water will run off from them by doing a water test on them.

How many people know the importance of the drip

A window sill should also have a drip formed on the underside of the sill, which means that the water running off the sill will not just run straight down and onto your brickwork, with the potential to cause penetrating damp or frost damage to your bricks. The drip is a  groove that is formed underneath the sill when made and runs the full the length of the sill. It’s usually the width and depth of a pencil or your little finger known as half round and breaks the flow of water, meaning it can drop down and drain away from the bricks or render. Over the years the drips can get clogged with dirt or usually painted over with numerous coats of paint making the drip useless, so make sure that good general maintenance stops this from happening because if the drip is not working properly then the property may suffer from penetrating damp or damaged brickwork.

Concrete Column Repair

Concrete Column Repair

Concrete Column Repair in Central London

This is one of London Structural Repairs recent projects. we carried out a Concrete Column Repair for a building contractor in the city of London. The Concrete Column was suffering from spalling, the steel reinforcing was corroding as there was no protective coating on the concrete and over time the weather elements have contributed to the corrosion of the steel and forcing the steel to expand and crack the concrete.
The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately six times the volume of the original material. Here at London Structural Repairs we specialise in diagnosing and designing repair methods for concrete structures and corrosion prevention.
