Concrete applications
HeatWork brings a new standard to concreting – it reduces curing time by 85%
When concreting in a cold climate, HeatWork can supply heat before, during and after pouring.
Before pouring
Before pouring, you can ensure frost-free material mass under the concrete construction. Once the reinforcement is in place, snow and ice in the formwork and reinforcement is easily removed using HeatWork.
After pouring
After pouring, energy and heat may be supplied in two ways. It may be done either by circulating hot liquid in HW pipes laid in the body of the concrete and firmly attached to the reinforcement prior to pouring, or by laying thawing hoses outside the formwork. The ability to supply heat dependent on the ambient temperature ensures progress, quality and economy in projects involving concreting.
Assures progress regardless of ambient temperature
Using HeatWork means that project progress can be planned well in advance and the concreting can actually be carried out in cold periods. Quality is assured and requirements for logging and documenting the temperature of the concrete during the curing phase can be satisfied, even if the air temperature is lower than 21 degrees C.
Hoses outside the formwork:
- The hoses are laid on the outside of the formwork before pouring
- Covered with HW Winter-Insulation
- The formwork is heated to the desired temperature
- Continuously variable adjustment of liquid temperature
HeatWork gives you full control over the curing process
Pipes in the concrete
- The HW pipes are attached to the reinforcement and cast in to the concrete foundations, floors etc.
- The distance between the hoses depends on the ambient temperature
- Continuously variable adjustment of liquid temperature
HeatWork gives you full control over the curing process
Hoses on floors or floor slabs after pouring:
- Vapour barrier/plastic is laid floors or floor slabs after pouring
- Hoses are laid on top
- Covered with HW Winter-Insulation
- Continuously variable adjustment of liquid temperature
HeatWork gives you full control over the curing process
Curing process
Robust assurance and control of the building process
By using HeatWork’s solution for the curing process you achieve a full 85% reduction in the curing time.Thus you save time and money on the project.The owner’s requirements for temperature in the concrete during curing are achieved and documented.
It takes around 8 days to achieve 75% hardness in the concrete when the temperature in the concrete is 21°C. If the temperature in the concrete is 4°C, it takes 25 days to attain the same degree of hardness and if the temperature in the concrete and its surroundings is -1°C, it takes 55 days to reach the same level.
HeatWork tailors and supplies complete designs, solutions and materials for small and large projects.
HeatWork ensures progress, quality and economy.
