CLEANING SERVICES FOR PROPERTIES AND CONSTRUCTION SITES
In construction, renovation and real estate maintenance, there are situations where Langh’s specialist skills are warmly recommended. For example, removal of earth and insulation materials, mold eradication and handling of dangerous materials are taken care of quickly and effectively with our specialist tools. We are also experienced with the prevention of further damage after fires.
Construction and insurance companies have long used Langh’s services. Our skills are equally available for use by both housing organisations and private real estate owners. Typical projects in small housing areas are unblocking of drains and vacuuming of base floor and roof cavities.
We offer our cleaning services with quick response time in the southern part of Finland.
Hydrodemolition of bridge and concrete structures
We use high pressure water to break concrete and other porous material with accuracy and good workmanship. With hydrodemolition, damaged parts can be removed without damaging healthy structures. The pressure levels of our Ultra High Pressure cleaning equipment are 1000 bar, 2 500 bar and 3 000 bar.
The main advantage of hydrodemolition is that the remaining steel comes up unbroken and clean with a surface that makes it easier to work the concrete further. With hydrodemolition the end result is always of high quality.
Removal of plaster and coating
Removal of plaster and coating can be achieved with two methods:
-
High Pressure cleaning
-
Wet Sandblasting
The removal of paint on level surfaces is successfully carried out with a surface cleaner which can be connected directly to a vacuum truck.
Facade renovations
High-pressure cleaning with a suitable detergent is a noteworthy, dust-free alternative when renovating facades.
Painted surfaces (even those that contain asbestos), plaster and other facade coatings are removed efficiently without irritating dust and sand emissions.
Removing graffiti
Removing graffiti and daub is done with a hot water cleaner and suitable detergent. Detergent is selected in accordance with the surface material.
Rinsing and imaging of pipe systems
We unblock, drain and rinse pipe systems and sewers with skill and accuracy, and our video camera equipment can be used to determine the condition of the target beforehand.
We also empty different kinds of wells, such as sand separation wells, storm water drains, oil traps, grease traps and cesspools swiftly and according to your needs.
Removal of soil and insulating mass
High-power vacuuming is an efficient method for removing soil and insulating mass. When renovating a floor/crawl space, removing soil and insulating mass often becomes relevant. In such cases, calling our high-power vacuum truck to aid is the best idea — especially if you're dealing with sand, concrete waste or crushed brick. The substance to be vacuumed can also be crushed at site, so you don’t need to wonder whether some pieces of the waste are too large for our truck to handle. Vacuuming and blowing shingle, macadam and gravel is no news to us. Vacuuming sawdust and wool is also handy with our high-power vacuum truck, as it prevents dust from being blown all over.
Vacuuming sawdust, shavings and straws from the roofs of old buildings is done dust free and swiftly with our high-power vacuum truck.
Prevention of further damage
After initial damage prevention and drying we will complete the further damage clean up. If necessary, we will arrange power generators and heat to the damaged areas.
For more than 30 years, we have carried out cleaning work and further damage prevention after fires. We are skilled, fast and cost-efficient in preventing further damage!
Drying and heating
Thanks to our effective drying container we can dry out areas and keep them warm no matter how cold it is outside. This helps prevent freezing damage, which could cause significant expenses.
Water jet cutting of concrete and steel
With water jet cutting, concrete and steel can be cut without vibration and sparks. This method is highly recommended for tasks such as making holes to tanks, floors and many fire-sensitive targets. Water jet cutting has been utilized in, for example, elevator renovations. In our opinion water jet cutting is preferable to diamond cutting as its more agile, allowing customer needs to be taken into consideration.
In special locations, such as ship tanks, utilizing water jet cutting means the space does not need to be gas free. Thanks to water jet cutting and our skilled and punctual staff the temperature of the location will not rise.
