| Repointing- The Age Old Problem
The basic problem with repointing is
that very few people enjoy doing it. It is slow, messy and there is very
little pleasure or profit in it. So, the natural temptation for the person
doing this work is to try to find ways of doing it more quickly, such as
not taking out enough of the old mortar, causing havoc with the dust from
raking it out or rushing the pointing and leaving an untidy finish. This
means that without a lot of close supervision, the person paying for the
work is never really sure of its quality or has to spend time sorting out
the chaos caused by the way the work is done. All too often what should be
a simple job turns into a series of problems for everyone concerned. |

Our systems include a unique range of power tools to ensure a proper depth of rake of the old mortar and our patented mortar pump and gun ensures new mortar is put back into the joint thoroughly.
We specialise in deep pointing and overhead works, raking and repointing of old hard cement-based mortars and our experience in solving both the technical and operational problems of repointing is second to none.
All our teams are trained to use this equipment accurately and carefully and repointing is their only activity.
We have extensive experience of brick, rubble, stone and ashlar properties as well as tunnels, kerbstones and paving. |

Raking - The Key to a Good "Key" |
|
|
The crucial element of repointing is to take out enough of the old mortar, but this is tiring, dirty and time consuming, so very few do it properly.
No one else has our range of raking tools and at Gun-point we see them as vitally important. Our basic tools have integrated dust guards with adjustable plates which, once set, ensure a constant depth of rake.
The guards are linked to our own specially designed dust extraction units which save the property and the operative from the mess and inconvenience normally associated with raking out.
There is thus little disturbance to the residents and other workers on site.
And because our teams are all full-time, they know how to use these tools with the minimum possible damage to the face.
We follow the recommendations of British Standard 8221:2000 and the BRE (a depth equal to twice the width of the joint subject to a minimum of
20mm) - but any depth may be specified - and more importantly, maintained.The Gun-point Mortar Pump
At the heart of our service is the patented Gun-point mortar pump and gun.
This low-pressure, high volume machine is light enough to go up scaffolding and small enough to go down tunnels.
It's powerful electric motor can pump any standard mortar mix as well as traditional lime mortars, and can accommodate all types and grades of gauged, masonry and cement mortars.
We like to use local sands that match the colour and character of the original finish but any colourants and other admixtures may be added to the mix as required.
