Resinfix have won an order to repair one of Nottingham primary and infant schools. Just a starter image of the extent of the concrete damage.
Concrete repairs lintels
Resinfix were asked to look at a problem with a recently built property that had water entering below ground leisure areas at the large detached property near Wolverhampton. The underground basement and swimming pool were half built under the house and half under the gardens. At the junction of the house water was pouring in quite fast when it rained. The work involved excavating the external patios to expose the wall junctions, injecting the gaps at the house wall with expanding leak sealing resin to seal around the supporting beams.Creating an external water dam in grout and reinforcement with tanking applied over externally. Internal injection to complete the seal. The work was designed insitu during the excavations and now the customers has their cinema and swimming pool areas back in use again after several attempts byother to rectify often making the situation worse.
The photos below show part of the supporting roof beam, the left hand picture has stalagtites from the leakages and the beam runs around 15 metres in length. The right hand image shows the junction now dry after extensive external work and resin injections.

Resinfix were asked to inject grout voids under an energy turbine base to ensure its bond to the underlying concrete structure. This was carried out by injecting and gravity feeding the grout into the hidden void through long drill holes driven externally. We then picked the correct resin to ensure full penetration. The void was injected from all sides under pressure to ensure 100% filling of the voids with an 80N/mm2 grout.
Injection grouting
Resinfix were asked by a significant Public sector department to inject low viscosity resins into virtually inaccessible areas to create precautionary waterproof membranes between floors of this prestigious building in central London. The resin was injected using lances and cameras to monitor the work.
Central London waterproofing
We have helped a property owner in Tilbury with a heaved cracked floor, concrete repairs and some brick stitching.
The cause of the cracking was not know fully before we arrived on the scene, however we discovered on excavating that the reinforcement within the floor had badly corroded. We felt this was probably due to sea and salt damage caused by flooding in the local area in the not too distant past as the corrosion was extensive. The raft the property was built on however was very substantial otherwise and all that was necessary was a localised repair to correct the damage. This then enabled the owners to sell the property. All work was overseen by a structural engineer. A previous company, who shall remain unnamed had attempted to inject the floor with slab lifting grout to level it but this had failed. Lifting any raft with slab lifting foam is almost impossible.

You can see our latest surveyor inspecting the damage, currently he is only paid in food!
However, he has his full safety harness on ;)

We prepared for levelled this old floor with an epoxy cement levelling compound near Newark this week from feather edge to 10mm depth. It was very uneven and difficult for the owner to utilise with furniture different leg height!
