Our Northern MonumentsDate: 29 July, 2021 | Author: Administrator
In working partnership with our much-valued client, Wigan Council. We are delighted to have been commissioned with the responsibility of restoring our local town cenotaphs and memorials. Up to now including Tyldesley's Cenotaph (as shown on the picture above), Leigh War Memorial, Wigan Cenotaph and we have recently tendered for the opportunity to restore Hindley's Cenotaph too!
All this work is very much appreciated as a local, Leigh (Northwest) based company we are proud to be given this opportunity to restore pieces of our local heritage. The scope of work to restore these stone structures usually consist of a sympathetic DOFF Integra steam clean to the substrate to remove years of dirt, algae, and other debris. Then to restore any damage to the stone masonry unit profiles/moulds using lime-based restoration mortars. And finally, to repoint any receding/missing joints with new lime mortar giving the monuments a really refreshed touch.
All practices improve the longevity of the structure by using all best practice techniques. The addition of lime mortars protects the stone profiles whilst allow the structure to release moisture. This is both beneficial to the lifespan of the monument and improves the aesthetic appearance for visitors to appreciate and enjoy.
We are Structures Group, Restoring the past one project at a time.
More information on DOFF Integra stone cleaning
What is this system?
Doff cleaning is a gentle process of cleaning stone using steam. Pressure and temperature are kept high at the nozzle end, and this is adjusted during cleaning. Generally, a temperature of 150 degrees Celsius will provide the needed results, but it is adjusted to suit an array of stonework substances during the cleaning process.
Doff cleaning is efficient on concrete because five litres of heated water and steam is at each minute released through the hose nozzle. It, therefore, works on concrete surfaces without causing any thermal shock, saturation, or damage to stone as you clean.
How does it work?
Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
The superheated water vapor will remove paint, moss, algae, fungi, and other biological matter and will also kill off spores. This means there’s then no need to use a chemical biocide during the removal process or as a protection against further biological activity. With absolutely 0% surface damage.
We recommend the DOFF for use on surfaces such as brick, stone, concrete, tiled (glazed and encaustic), wood, faience, and terracotta.
