- What are the benefits of polishing an industrial concrete floor ?
There are five main elements to the benefits of polishing concrete floors, firstly you can extend the life of the slab almost indefinitely by creating a surface that is harder and more durable, secondly this smooth surface stops the floor from wearing and this stops dust forming from the surface wear by tyres and forklifts. Number three is easy cleaning, a polished surface is easier to clean, and four is the benefit of the reflection of light from lights and skylights that can reduce your lighting costs and finally num ber five is the benefits to the environment, concrete is one of the worst materials in construction but its life extension has huge positive effects.
2. What is the most cost effective method to remove old bolts from a concrete floor and how should the surface be left ?
Removing bolts is a time consuming and labour intensive process. Initially drilling the surface with a core drill and water to cool the head and suppress the dust. The core is then removed with the old bolt and sheath. The hole is then cleaned out using a vacuum and once dry cxan be filled with an extremely hard repair material. This is left to harden and eventually ground down level using either a large scale floor grinder or hand tools.
3. Why shouldn’t you clean a cladded building with sodium hypochlorite ( soft washing)
Soft Washing and the use of ” bleach is probably the worst thing you can do for the environment. It kills all plant life it comes into contact with and does nothing to protect the surface of the building. A m ist of bleach covers everything within 20-30 metres and there is evidence of some operators appearing with both bleached hair and clothes after just a mornings work. If somebody suggests this just say NO !
4. Are drones good for cleaning ?
Simple answer is No. Despite the marketing material the truth is that nothing cleans a surface better than a detergent and some gentle abrasion, either a soft brush or sponge, A drone cannot touch the surface and therefore relies entirely on water pressure and chemicals. When cleaning with water pressure alone it is im possible to maintain a consistent distance from the surface which results in streaky cleaning, sometimes only noticeable some weeks after the work is done as the algae can grow back faster where its not been removed completely. It’s also impossible to deal with stains where gaskets are bleeding without physically working hands on.
5. Are lasers useful in building cleaning ?
Laser technology is moving quickly in to building cleaning and is ideal for stone, concrete, brick and marble surface. It can clean without chemicals, water, noise or dust and the only output is the vaporized material on the surface. Some people are poorly informed and assume it is dangerour, however there are so many safety systems in place and the laser beams used are a frequeny that do not travel far making them inert withing 10-20 metres from the head.
