golvplatta

A golvplatta is a type of floor slab used in building construction, commonly referring to a concrete slab at ground level or prefabricated floor panels. It serves as a structural base that carries imposed loads, distributes them to the foundation or ground, and provides a flat surface for finished flooring. The term is widely used in Scandinavian construction practice for slabs on grade (platta på mark) and for precast floor elements.

Materials and types vary with application. Monolithic cast-in-place reinforced concrete slabs are typical for ground floors, often incorporating steel reinforcement, a damp-proof membrane, insulation (such as EPS), and edge insulation or frost protection. Precast hollow-core slabs and steel- or timber-based floor panels are used for multi-storey buildings where spans, speed of construction and prefabrication are priorities.

Installation involves ground preparation and compaction, formwork or placement of precast units, reinforcement and joints, concrete casting or assembly, and curing. Key considerations include load-bearing capacity, reinforcement detailing, shrinkage and control joints to limit cracking, thermal performance, moisture control and radon protection where relevant.

Advantages of golvplatta systems include durability, good thermal mass and compatibility with underfloor heating. Disadvantages include weight, limited adaptability after construction and potential cracking if poorly designed or executed. Design and construction should follow applicable national building codes and industry standards for structural safety, thermal performance and moisture protection.
