Igloo CPM has a trade name AssaFlex UK, which deals specifically with the supply and installation of bridge components. This part of the company has been active since 1996. We offer to install bearing pads and expansion joints on new projects such as Roundwell Bridge in Kent or replace an existing one. There are always some structural elements involved in placing bridge bearing pads or expansion joints, and AssaFlex would carry out the work.

Concrete

• Strengthening of defected RC beam, column, etc.
• Use of FRP (Fibber Reinforced Polymer)&CFRP (Carbon-Fibber-Reinforced Polymer)
materials have gained acceptance for civil engineering infrastructure as a result of substantial research and development efforts over the past 20 years.

FRP is an attractive choice for strengthening structures since it is often cost-effective, easy and quick to install, and does not significantly affect the mass or geometry of a structure.

FRP composites vary in strength depending on the type of fibber used.

While glass provides a tensile strength nearly equal to mild steel yield strength, carbon composites (CFRP) provide a tensile strength that vary from twice to five times the yield strength of mild steel. While both FRP composites have tensile stiffness lower than that of steel, carbon composite stiffness is twice to five times the stiffness of glass composites. FRP composites have approximately one fifth the weight of steel.

FRP Application systems provide a very practical tool for strengthening and retrofit of concrete structures, and are appropriate for:

• Support for bending stress
• Shear strengthening
• Column confinement and tensile strenght improvment

FRP systems have also been successfully used for seismic upgrading of concrete structures. These applications include mitigating brittle failure mechanisms such as shear failure of unconfined beam-column joints, shear failure of beams and/or columns, and lap splice failure. FRP systems have also been to confine columns to resist buckling of longitudinal steel bars. These FRP schemes increase the global displacement and energy dissipation capacities of the concrete structure, and improve its overall behaviour.

Because of the resistance to corrosion, FRP composites can be utilized on interior and exterior structural members in all almost all types of environments.

FRP composites are designed to last for the service life of the structure

General use of FRP:
FRP systems have been successfully used to strengthen buildings, bridges, silos, tanks, tunnels, and underground pipes.

Underpinning:

Underpinning is a method used to increase foundation depth or repairing faulty foundations.

Cracking:

Cracks can appear vertically or horizontally in concrete wall, column or,…

Flooring
Fine Crack Repair: is a solvent free, low viscosity epoxy resin designed for filling smaller cracks, voids and thin section “blow outs” or craters in concrete floors.

Epoxy Adhesive Paste:
For bigger horizontal joints. Hard and tough enough to protect joint edges from heavy wheel loading, but possesses sufficient flexibility to accommodate 10% movement of the joint width.

Flexible Joint Filler
Where cracks are deep we suggest using Flexible Joint Rods which are foam strips to ‘pack out’ before using Flexible Joint Filler.
Elastomeric repair paste; specially developed and with a high degree of flexibility for use as a caulking compound and joint filler. This product is used for larger cracks or opening.

Brick works
RP Paste & Rod: In the case of old brick structure when it comes to restoration and repair there is the need for flexibility, and use of GRP materials exactly does that providing structural repair.

The Brick stitching system:

allows the cracked wall to behave as a reinforced non-fractured unit.  Having a galvanised steel bar shaping the crack stitch rods physically interlock with the bonding agent and display a unique and resilient torsional spring-like quality that allows small amounts of wall movement and recovery to occur without brittle failures.

Incorrect pointing
Inappropriate mortar mix can cause problems in both the mortar and the stone itself. The main problem is usually related to having too strong a mortar. This can be corrected by use of correct mix and jointing.

Stone
Similar to work on Brickworks, Helifix or similar product is installed into the bed joints of a stone wall. The galvanised bar is flexible to allow it to follow the contours of the cracks. The bars are being bedded in high strength grout which will be left recessed ready to be pointed so that only the mortar pointing is left visible. These bars are used to reinforce and tie the building back together.
