Balcony Restoration

Balcony Restoration In North London

We provide home owners and business owners who have problems with there victorian balconies with our balcony restoration service.

London Structural Repairs have been carrying Balcony Restoration works for many years in and around London.

Clients often leave they’re balconies un maintained because they feel because it is on the exterior of the building it won’t effect the structural integrity of there property, but this is far from the truth.

Balconies left unprotected from the harsh weather elements usually end up costing the client a lot of money to put right in the end as balconies often become unsafe to use or for people to walk underneath them.

General routine maintenance can stop your balcony from becoming unsafe, unsightly and for the need of an expensive balcony restoration.

A unsightly balcony is often the first impression of a home and could devalue your investment. A well kept and nice aesthetics balcony would add value to your investment.

Our balcony restoration services include structural surveys / repairs and waterproofing and decoration.

This is one of our projects where the clients property needed the structural integrity of the balcony restored and waterproofed from the top.

The concrete slab underneath had a rusting filler joist and cracks. Our balcony restoration team repaired the spalling concrete and resin injected the cracks.

The asphalt on top had become porous, letting in water and causing structural damage to the concrete slab.

We applied a Sika waterproof non slip membrane system to stop anymore water from tracking through from the top of the balcony and causing damage to the flat beneath the balcony.

This system is a long term cost effective solution to these kind of problems.

We can carry out your Concrete Lintel Repairs for you with our professional services.

Has your concrete lintels cracked, spalled or broken, well you have come to the right place as we can help.

Concrete lintels can become damaged if not routinely maintained to stop water ingress.

Water and moisture will cause the steel reinforcement to rust and eventually expand, resulting in damaging the lintels.

Pieces of concrete or stone will crack or even drop off making your lintels unsightly or even unsafe if they are above head height.

We carry out concrete lintel repairs with fine detail, leaving your lintels looking as good as new.

Our concrete lintel repairs get carried out in a sequence.

We cut away, remove the loose and damaged concrete from the lintels.

Steel Reinforcement bars can cause you a serious problem

The steel reinforcing is either cleaned or replaced and primed to stop any future further rusting.

Oiled shutters are put in place and then the concrete is recast to the original profile using specialist mortars or grout.

It is important to add a drip on the underside if needed.

Shutters are struck when the concrete has cured for long enough.

We advise that concrete lintels are either painted with coloured masonry paint or clear paint to stop moisture penetration.

It is usually cheaper and less disruptive to repair the concrete  lintels instead of replacing them.

Replacing concrete lintels could have its own problems structurally to a building.

Good routine maintenance could save you costly repairs in the long run.

This is one of our concrete lintel repairs projects carried out to property in East London.

The home owner needed the lintel repaired so the sale of their house could go through.

London Structural Repairs acted quickly to help them with this problem with our repair technique.

Structural integrity was restored and the house was sold.

London Structural Repairs are experienced experts in resin injection concrete crack repair. This one of our recent projects at the historical  Lincoln Inn Fields Great Hall and Library where we were contracted by the main contractor on site to deal with a number of concrete crack repair to a basement reinforced concrete slab.

Lincoln Inn Fields is Londons largest public field and is steeped in history with strong links to the British legal system. The Lincoln’s Inn Fields Great Hall and Library is home to some of Britains rarest legal books. The building is bold and elegant with a gothic look about it.

We were asked by Graham construction to find a structural repair solution because there were  concrete crack repair that was on a reinforced concrete basement slab. The concrete slab was cracked in various locations and varied in length. The cracks were hairline and the client didn’t want us to carry out concrete crack repair by means of mechanical breakout incase the structural integrity was damaged further.

London Structural Repairs solution was to inject the cracks using Fosroc LV crack injection system. This a low viscosity material that means it has good movement through tight cracks, this material can be used if the crack is sealed on the opposite side of the injection. If the crack can’t be sealed from the opposite side then you need to use a higher viscosity material such as Fosroc TH which is a Thixotropic resin.

The first thing we had to do was make sure the concrete crack repair area was clean and free from dust. We then face filled the cracks and installed the injection ports. We then injected the Fosroc LV into the first port and used the release valve to let any trapped air out and waited for the resin to show in the next port before moving along each one in sequence.

The project took 2 days to complete and we removed the injection ports and plained the face filler to remove from the concrete.

Failed Concrete Beam Repair In London

This is one of our recent projects for a property development company in the heart of London. London Structural Repairs were asked too provide a failed concrete beam repair solution to a 6 metre reinforced concrete beam which had damage to the top section. The client was worried about the beam collapsing so LSR operatives fitted RSJ’S with propping to a engineers specification to stop any chance of the concrete beam from collapsing or cracking during our remedial works. The on site engineers asked LSR if we could Hilti Ferroscan The failed concrete beam as well as the two concrete columns connected to the beam to see the steel reinforcement make up as well as to determine bar sizes which the Hilti Ferroscan does with ease but only trained competent persons should attempt to use this complicated piece of kit. The engineers on site presumed  that the concrete slab above was tied in connected to the concrete beam but our investigation works confirmed that the concrete slab was not connected and just sat on top of the beams, the slab was probably precast and crane lifted into place at construction.

The failed concrete beam Repair solution system we used was Sika concrete repair mortar system. We first carried out a hammer test survey to determine where the defect – delaminated concrete ended and marked this out on the concrete. We then had too saw cut the marked concrete with a dustless concrete grinder attached too a M class hoover to protect all persons within the building from dust inhalation, after this we  had too break away the concrete using Hilti mechanical breakers with low vibration to eliminate HAVS to our workers. We then added more steel reinforcement to the repair area and then made the repair using the Sika system to the manufacturers specification.

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.

Check out our concrete repairs service page

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.

LSR are NVQ qualified concrete spalling repairs specialists who can provide you with a one stop shop service.
