Scientific repair solutions that extend the life of ageing concrete structures, safely and sustainably.
Our engineered repair solutions restore and enhance concrete structural performance. Taking a systematic, science-based approach, these systems address root causes of deterioration to provide long-term durability and structural integrity.
Rather than masking symptoms, our methodology addresses underlying deterioration mechanisms, providing durable solutions for issues ranging from load capacity enhancement to damage remediation with minimal disruption.
Our advanced Fibre Reinforced Polymer fabrics deliver high-strength, lightweight reinforcement for concrete structures. These engineered composite materials offer exceptional strength-to-weight ratios for diverse strengthening applications.
Utilising high-tensile carbon or glass fibres in specialised epoxy matrices, FRP wrapping creates powerful structural reinforcement with minimal dimensional impact. Ideal for retrofitting existing structures with minimal architectural changes.
Our engineered Carbon Fibre Reinforced Polymer laminates represent the pinnacle of concrete strengthening technology. These precision-manufactured pultruded strips deliver exceptional tensile reinforcement with minimal profile.
Manufactured through advanced pultrusion technology, the laminates feature perfectly aligned carbon filaments for maximum longitudinal strength, with tensile values approaching 3,000 MPa. Available in widths up to 150 mm and thicknesses up to 1.5 mm, they bond to structures using specialised structural epoxy adhesives.
Our steel jacketing methodology provides efficient structural reinforcement with minimal dimensional impact, strategically positioning steel sections around structural elements to significantly enhance performance.
The system typically employs angle steel positioned around column or beam corners, secured with through-bolts or welding, and often filled with non-shrink grout to ensure composite action between the existing element and the steel reinforcement.
Micro concrete jacketing strengthens existing structural elements through an additional encasement of free-flowing, high-strength micro concrete with properly detailed reinforcement, significantly enhancing load-bearing capacity and structural resilience.
The dual-shrinkage-compensated micro concrete flows into congested sections without vibration, increasing cross-sectional dimensions and reinforcement to enhance axial, flexural, and shear capacity.
Our specialised expansion joint solutions accommodate controlled movement in concrete structures. These engineered systems prevent the stress-induced cracking and structural damage that occurs when thermal movement is restrained.
Designed for diverse applications including pavements, bridges, buildings, and metro lines, these systems provide the necessary structural discontinuity while maintaining waterproofing and load transfer characteristics.
Our precision injection grouting systems restore structural integrity by filling internal voids and cracks. Available in cementitious, epoxy, and polyurethane formulations, these specialised materials penetrate deep into concrete defects.
Engineered for applications from crack sealing to void filling and soil stabilisation, the grouts feature carefully controlled rheological properties, setting characteristics, and strength development profiles to suit diverse repair scenarios.
Several indicators suggest the need for structural assessment:
Our structural engineers conduct comprehensive assessments using non-destructive testing, structural analysis, and material evaluation. Early detection typically allows more cost-effective remediation.
FRP systems excel where minimal weight addition and space constraints are critical. Best for flexural strengthening of beams and slabs, confinement of columns, and seismic upgrades where space is limited.
Steel jacketing provides excellent confinement and shear reinforcement with minimal thickness increase. Particularly effective for columns requiring significant ductility enhancement.
Micro concrete jacketing delivers the most substantial increase in both strength and stiffness, with comprehensive reinforcement for all failure modes and excellent fire protection. Best for severely damaged elements requiring major capacity increases.
The optimal solution depends on access, space, load requirements, installation time, budget, and service environment. Often a combination of methods provides the most efficient solution.
FRP systems typically provide 50+ years of service in normal interior environments and 25-40 years in exposed conditions depending on UV and mechanical protection. Steel jacketing, properly protected against corrosion, delivers 30-50 years of performance. Micro concrete jacketing typically matches or exceeds the original structure's designed service life, providing 50+ years when designed with appropriate quality and cover depth.
For critical structures, we incorporate durability enhancement measures and recommend periodic inspection protocols.
