Qualislab specializes in designing and constructing In Situ, Rib and Block, and Polystyrene concrete slabs. We follow a precise process involving formwork, steel reinforcement, and concrete casting, ensuring high-quality results backed by over 18 years of experience.
Raft foundations spread the building’s load across a large surface area, reducing ground stress and providing stability on volatile soils like clay, sand, or dolomite. Acting as a reinforced slab, it moves with the ground to prevent damage, making it a cost-effective alternative to deep strip foundations.
Concrete beams are used to provide extra support for slabs over wide spans or for aesthetic purposes. They carry vertical loads by resisting bending. Qualislab expertly constructs various beam types, including arched, ring, up-stand, down-stand, and internal beams, according to architectural or engineering designs.
Stairs are typically cast along with a slab and require skilled carpentry and construction knowledge. We specialize in building concrete staircases, having created many unique designs over the years. Like slabs, stairs are cast in-situ with formwork and steel reinforcement based on engineers’ specifications.
Reinforcing steel bars enhance the tension strength of concrete structures. A structural engineer provides a layout for steel placement, which is then fixed by Qualislab’s expert teams. After installation, the steel is inspected and certified by the engineer.
Concrete retaining walls are rigid structures used on construction sites to support soil laterally, accommodating elevation changes. They hold soil at different levels on each side, preventing it from sloping naturally.
