GRP Pitched Fibre re-lining
Drain Pipe Renovation with GRP Lining
* No Excavation
* Minimal Disruption
* Improved Flow Characteristics
GRP lining is a proven and established method of placing a new pipe within an existing damaged drain pipe without excavation and with minimal disruption.
The new pipe material is similar to GRP (glass reinforced plastic) and in all cases will be superior in quality and strength to the pipe which it lines. The new pipe is moulded into the damaged pipe by an ingenious method called 'inversion' using water or air pressure, fitting it tightly against the wall of the existing pipe. When the inversion is complete the new pipe (which is originally flexible) is now rigid, resulting in a strong, tough pipe tightly fitted within the existing pipe with only a minimum loss of cross section of approximately 6%. |

GRP liner
The GRP liner pipe is manufactured from a special dense impermeable felt and is designed and tailored to fit exactly the internal dimension of the pipe to be refurbished. The thickness of the liner material can be varied according to design specifications required. A special resin containing an activating catalyst is impregnated into the liner pipe prior to installation.
The lining is suitable for sewers, culverts, verticle rain water down pipes etc. It can also be used to seal tanks, chambers and manholes etc. GRP lining is resistant to most aggressive chemicals and can withstand extremely high temperatures. The customer will benefit from the lining repair process in many ways.
| 1 | Eliminates costly excavations and general disruption to the property |
| 2 | Capable of repairing and curing leaking & open joints, root intrusion, cracks and all other associated pipe failure. |
| 3 | Suitable for domestic, industrial, commercial and municipal applications. |
4 |
Achieves permanent structural repair. |
5 |
Guarantees improved flow characteristics. |
6 |
Will withstand ground movement far in excess of traditional drainage materials such as saltglaze, clayware, concrete etc |
| 7 | Any cross-sectional loss is adequately compensated by increased flow efficiency. |
| 8 | The process is accepted by Local Authorities, Loss Adjusters, Surveyors, Civil Engineers and Architects etc |
| 9 | Continual lengths of up to 50 metres can be installed in one length. |
| 10 | Minimum lengths of 0.5 of a metre can be installed for a local structural repair. |
| 11 | The materials used are extremely strong, abrasive resistant and do not rely on the existing pipe for its structural integrity. |
| 12 | A GRP lining refurbishment will be ready for use within hours of installation. |
| 13 | Very cost effective, up to 75% savings have been achieved by GRP lining over conventional methods. Superior quality at lower cost equals good value for money. |
| 14 | Installations are fully guaranteed. |
