Location
Latvia
Residential construction – basements & foundations
Used for
– Basement and foundation walls
– Load-bearing masonry walls
– Partially buried structures
– Residential and light civil buildings requiring enhanced durability
Installation
– GFRP rebars placed vertically inside hollow blocks
– Steel rebars placed horizontally in bond beams or lintel zones
– Cavities filled with concrete or grout
– Fully compatible with standard basement wall construction workflows
Why a GFRP + steel hybrid system
Corrosion resistance – GFRP rebars are used in moisture-prone vertical cavities, eliminating corrosion risk in basements.
Steel for concentrated loads – Steel reinforcement is used selectively where higher stiffness or local load transfer is required.
Balanced durability and cost – Hybrid approach reduces long-term corrosion risk while maintaining conventional detailing logic.
Standard masonry compatibility – Installed using familiar construction methods and grout filling.
Key advantages
– Reduced corrosion risk in basement environments
– Longer service life compared to all-steel reinforcement
– Improved crack control in masonry walls
– Faster handling and installation of vertical reinforcement
– No change to conventional block-laying methods
