Drainage Surveys

Newman’s are now undertaking CCTV drainage surveys for all of our clients to benefit our range of services specifically linked with the repair of buildings.

We carry out subsidence investigations and repairs and as a part of this package we inspect drainage systems for fractures and failures which may be the cause of movement to a building.

Our technicians are able to carry out a detailed survey using the latest CCTV technology which also records the entire inspection. We will then provide a report identifying the design and construction of the drainage and also any defects and the appropriate most cost effective solution for repair.

We can carry out pach repairs and linings whilst on site or at a later date if required. Our drainage services can be carried out for any works not only our own investigations.

If you require a cost for a CCTV drainage survey then please call 0207 559 1410 for any enquiries.

Cracks Between Internal & External Walls

Cracking where the party wall or partition wall meets external walls is a common problem caused by a lack of connection between the two walls.

Often the connection between the two walls is just a cement fillet which provides no connection or protection against outward movement.

In order to tie the two walls together we utilise the twistfix bed joint reinforcement by chasing out the external bed joints, drilling into the partition wall and chasing into the internal partition wall providing an L shaped tie resisting any further movement. The cement fillet is raked out to a depth of 80mm and injected with twistfix cementitous grout providing a permanent solution guaranteed against failure for 10 years.

Concrete repairs and Anti Carbonation coatings are underway in North London to a commercial shopping precinct and the social housing above as vertical and horizontal cracking had appeared across the structure. the cause of cracking was identified as lack of cover to the concrete reinforcing causing oxidastion of the reinforcing rods and spalling the concrete. An anti carbonation coating is also being spray applied to the concrete structure after the concrete repairs.
