GRP LINING

GRP Lining is a significant application in the fiberglassindustry. It has diverse applications including corrosionresistance, structural strengthening and waterproofing.

It can be found in most if not all water storage tanks,sewerage tanks, chemical storage tanks, tank roof lining,manholes, sewerage sump pit, cooling towers, chemicalplants, firefighting networks, pipeline networks andwater transmission pipelines etc.

Special grade resins are used to attain various properties which allow the GRP Lining to withstand resistance to fungi& algae, strong acids chemical and high temperature. It isan effective alternative to component replacement.

GRP Lining will completely and seamlessly seal thecracks, leaks, corrosion and flaking materials. It offersa new life to damage/eroded walls providing a long term,secure environment at a fraction of the cost of total rebuild.

Mechanical Properties
No metallic corrosion High strength to weight ratio Easy maintenance Corrosion proof Leak free Chemical resistant Flexible Impact resistant
Materials of Construction
Specification
Resin with good water and chemical resistant Chopped stand mat fiber (CSM) Catalyst Gel coat Thickness 2mm to 10mm as per requirement Corners - additional GRP strips in all corners and joints Final application - manual layer - coat process and gel coat properties.

Method Statement for installation of GRP lining
1 After surface preparation and removal of dust, one coat of resin coating is applied using roller brush
2 Ensure that the resin filled in all voids of concrete surface so as to avoid the formation of air bubbles
3 Steel roller is used for proper impregnation and to remove any air entrapment
4 Ensure the CSM (Chopped Strand Mat) is completely wet
5 Continue the laying process on the remaining area overlapping up to minimum 20mm applied
6 After one layer of laying apply resin and put second layer of CSM over the fist layer
7 Again apply steel roller
8 Ensure again the CSM is properly wet. continue laying application up to the required thickness
9 Gel coat will be applied for better finishing to avoid pinholes and it act as an anti-algae resistance
10 Allow sufficient time for curing (minimum 48 hours)
11 During lining many materials are used, ensure that the site is cleaned properly ans wastage are disposed off before inspection / handing over
