Uniaxial geogrid in Malaysia.
Infraconcrete Construction Sdn Bhd supplies and installs uniaxial geogrid across Malaysia through sole STRATA Geosystems Asia distributorship via Starwall Sdn Bhd. StrataGrid polyester (PET) range, tensile 30 to 1000 kN/m in machine direction. PVC-coated polyester yarns for chemical and biological durability. Six applications: MSE wall reinforcement, reinforced soil slope (RSS), basal reinforcement on soft ground, segmental retaining wall, bridge abutment, geotextile-encased columns. Long-term design strength data per BS EN ISO 13431 included with every reinforcement-grade order. CIDB G7 installation crew, ISO 9001:2015 quality system.
One-direction tensile for structural reinforcement.
Uniaxial geogrid is a polymer mesh with high tensile strength in one primary direction (machine direction, MD) and minimal tensile capacity in the perpendicular direction (cross-machine direction, CD). The directionality makes uniaxial geogrid the design choice for reinforcement applications where the tensile load is in a known single direction: MSE wall (tensile horizontal into backfill, resisting earth pressure), reinforced soil slope (tensile horizontal, resisting slip surface), basal mat (tensile horizontal, resisting embankment lateral spread).
Most uniaxial geogrid in the global market is manufactured from polyester (PET) yarns coated with PVC for chemical and biological durability. StrataGrid is STRATA Geosystems' high-end range, supplied in Malaysia exclusively through Starwall Sdn Bhd. Tensile strengths 30 to 1000 kN/m. Manufactured by hot-drawing PET yarns through a polymer matrix, then bonding into a rectangular grid pattern.
Contrasts with biaxial geogrid (equal tensile both directions, PP material, used for road base granular interlock) and triaxial geogrid (three-direction load transfer, PP, advanced subgrade stabilisation).
Where uniaxial geogrid actually goes.
1. MSE wall reinforcement layers
StrataGrid 50-200 kN/m typical, horizontal layers in compacted backfill, vertical spacing 0.4-0.8 m, length 0.7H to 1.0H. Faced with modular block (StrataBlock), precast panel (StrataWall), gabion, or wrapped geogrid. Design per BS 8006-1 + FHWA-NHI-10-024. See MSE wall.
2. Reinforced soil slope (RSS)
StrataGrid 30-150 kN/m for slope angles 30 to 70 degrees. Slip-circle factor of safety analysis with geogrid tensile capacity added on critical slip surface. Vegetated face or geocell facing. See RSS.
3. Basal reinforcement on soft ground
StrataGrid 100-500 kN/m at embankment base over peat (Sarawak/Sabah interior, Pahang east), soft marine clay (Klang Valley alluvium, Pasir Gudang, Pengerang). Resists lateral spreading. Pairs with PVD for accelerated consolidation. See basal reinforcement.
4. Segmental retaining wall (SRW)
StrataGrid 30-150 kN/m with modular block facing (residential, commercial, township). Connection capacity per NCMA SRW Design Manual. Heights 1-8 m typical with proven connection systems. Architectural finish through textured block face.
5. Bridge abutment with reinforced soil
StrataGrid 100-300 kN/m for bridge abutment with reinforced soil approach embankment. AASHTO LRFD design alignment with bridge structure. Precast panel facing (StrataWall) for federal highway aesthetic. Federal corridor scope (EKVE, ECRL approaches).
6. Geotextile-encased stone columns and piles
High-strength StrataGrid (typically 80-200 kN/m hoop direction) wrapped around stone columns or piles for radial confinement in very soft soils. Soft-ground improvement combined with stone column or pile foundation.
