Raft foundations

Raft foundations

PrīmXComposite Raft foundation is the ultimate raft design that is much faster to install, is waterproof, is safe for workers and perfect for limited building space. This is an optimal solution for fast-track construction.

In traditional designs, raft (also called mat foundation) is steel bar reinforced concrete slab resting on the soil, while the foundation plate is covering the entire base of the building. For this solution installation of steel reinforcement bars is the most time and labor consuming activity. Traditional concrete shrinks, cracks and is not waterproof. Therefore foundations need extra waterproofing: costly membranes, extra time and costs for installation.

Our technology – PrīmXComposite - uses a steel fiber reinforcement system instead of large steel bars. It also contains special anti-cracking and anti-shrinkage additives.

By eliminating the need for steel bar installation, PrīmXComposite ensures impressive time and work force savings. On average, we save 30% of raft foundations installation time.

With our method there are no dangerous activities for workers in construction zones (no huge steel bar unloading, stumbling on reinforcement mesh, getting hurt using rebar cutters etc.).

Special shrinkage compensating additives prevent material from cracking and therefore ensure a possibility to build watertight foundations, saving on expensive waterproofing membranes.

PrīmXComposite allows us to ensure efficient gas tight solutions as well.

Often there is limited space in construction areas that can cause serious problems dealing with long steel reinforcement bar and other large construction materials. PrīmXComposite Raft foundations in turn is perfect for limited working space.

PrīmXComposite Raft foundations can also simultaneously be used as floor in warehouses, parking garages, industrial buildings and other places. PrīmXComposite Raft solutions are also available as floating foundations for wind turbines.

To summarize, PrīmXComposite Raft foundations allow:

  • Much faster construction (30% on average) as no steel rebar installation needed
  • Less manpower involved in construction

  • Waterproof foundations – no extra costs for membranes etc.

  • Efficient gas tight solutions

  • Safe construction - no dangerous steel bar installation works

  • Perfect for limited building space.

During our 20 years’ experience in concrete works, we have installed raft foundations for various structures.
