Scaffolding and weatherproofing for timber construction
Are you about to start or are you planning a timber construction project?
Developers almost always expect the construction of a timber-framed building to be carried out under a weather shelter after the foundation phase. When you need information about different weather shelter options, let us help you choose the best and most cost-effective weatherproofing solution.
In timber construction projects, weatherproofing is important for both durability of the structures and the quality of the work. Weatherproofing helps ensure that timber buildings remain safe, durable and in good condition throughout their lifespan. The advantages of using weather shelters include uniform working conditions and shorter drying times. Timber construction produces less construction dust than to concrete construction. Weather shelters also improve comfort and safety at construction sites. In hot weather, the white roof of a weather shelter protects workers from direct sunlight, and air-permeable mesh walls help keep the temperature below 20 degrees Celsius.
Rising RamiTower or TG Tower with fixed scaffolding frame
Installing timber wall and roof elements under a weather shelter poses its own challenges. The elements tend to weigh several thousand kilos, and it is almost impossible to move them horizontally without having to open the weather shelter. Opening the weather shelter is always a moisture management risk in Finnish weather conditions.
Space-saving solution
RamiTower is a rising weather shelter with an overhead crane. It is an ingenious solution for weatherproofing and on-site logistics. RamiTower saves space in confined urban environments. The length and height of the weather shelter can be adjusted as required. The shelter’s own crane can lift elements weighing up to 4,000 kg. There is no need to open the weather shelter as all lifting work can be done from the ends. RamiTower is not raised to its full height straight away; instead, it is raised as floors or work stages are completed. RamiTower’s own motors are used to raise the weather shelter.
RamiTower is a safe choice
Our clients have told us that RamiTower is a safe choice for them because the costs related to it are easier to predict. Other weatherproofing solutions have more variables which may at times increase the overall costs of weatherproofing. With other alternatives, weather conditions, any requirements to open the shelter, external lifting and material transportation must be taken into consideration. If it rains or there is a strong wind, the installation must often be postponed, which may impact the schedule and increase costs. Other alternatives also have an increased risk of water damage and construction site drying needs – risks that, if realized, will also increase costs.
New on the market – TG-Tower
The latest innovation in the weatherproofing market is our TG Tower. The weather shelter is completed in one go, in the same way as free-standing weather shelters. Inside the weather shelter, crane girders are mounted on a TG shoring tower on which the actual remote-controlled overhead crane is lifted. The difference with the rising RamiTower shelter is that the walls of the shelter can be completely covered with blue Windsafe debris netting, but the cost-effective height of the shelter when free-standing is maximum 20 m. The width of the overhead crane is 20–26 m.
We have had on-site challenges, but when you choose professional and reliable partners, solutions have always been found.
Free-standing weather shelters
When you need a weather shelter without additional internal support structures inside the shelter that may complicate construction, the solution is a free-standing weather shelter. With free-standing weather shelters, we can create a kind of open hall inside which all lifting and installation of elements is done usually by a truck-mounted loader crane, without there being a need to open the roof of the weather shelter. The demand for free-standing weather shelters has been steadily increasing. We installed Finland’s first large-scale free-standing weather shelter in Pori in 2017. The largest free-standing weather shelters have been around 4,000 m2 in size and 50 meters in span.
Today, the same method of weatherproofing is used on numerous sites around Finland. The growing spans and the variety of buildings pose a challenge for the design and implementation of freestanding weather shelters. These challenges can be overcome with good planning, our experienced experts and our versatile and extensive fleet of equipment.
The CLT timber elements for the frame phase are manufactured in a factory and transported well protected directly under the weather shelter without the need for intermediate storage. This prevents the elements from getting wet at any stage and ensures that the dry chain is not broken.

Weatherproofing innovations
Lifting materials into the weather shelter? Fixing scaffolding to structures? Making logistics work inside the weather shelter? Effects of different building materials on the implementation of weatherproofing? Weatherproofing requirements of the future?
The need for weatherproofing increases every year because of the Kuivaketju10 operating model for moisture management, among other things. We respond to market demand with new weatherproofing solutions and innovations. In recent years, a need has risen for increasingly wide spans for weather shelters. Currently, our equipment allows for a 60-meter span for a weather shelter, without intermediate shoring.
We are also developing other solutions for lifting and logistics needs inside the shelter. At present, larger weather shelter opening needs can be carried out using protection bays moving on shift rails, by hand or with winches. Being able to quickly open and close the weather shelter facilitates and improves the dry chain and promotes occupational safety.
Dynamic development is a key part of our operations. We anticipate our clients’ needs and stay at the forefront of development in the scaffolding and weatherproofing industry.
