Case Study: Fibreglass Gully Lining

The client

When you make essential interconnect components for the military, aerospace and industrial markets, your facilities need to be in top shape. One of our clients knew this, but faced a problem.

The problem – a leaking gully

A leaking gully posed a serious environmental threat if chemical runoff in the gully leaked into the concrete and earth below.

Having previously worked with Sui Generis to line their bunds, our client knew exactly who to call to effect a high quality repair and sealing of their gully with minimum downtime.

The solution – a fibreglass lining

About 20m long, the gully or pit needs to collect and channel runoff from chemical tanks used for dipping components.

But as it was tiled, corroded grouting meant the surface was quickly coming apart.

We recommended completely lining the floor and walls of the gully with GRP fibreglass for a strong, chemical-resistant coating.

Fast and efficient gully lining

A three-man Sui Generis team took just four days to complete the repair and line the gully. And because the work was undertaken over a bank holiday weekend, disruption was kept to a minimum.

Now that the work is complete, the gully can handle chemical runoff without wear or corrosion – for many years to come.

Fibreglass gully lining, from preparation to completion

Special surface cleaningSpecial surface cleaning

Chemicals running through the gully had corroded the grouting between the tiles, causing many to become displaced.
Sui Generis first had to carefully clean the affected area and remove the loose tiles before the repair could begin.

Floor preparationGully preparation

Because the walls and floor of the gully were tiled and it was classed as a sensitive area, grit blasting would have been unsuitable. So we applied a special primer to the surface and fitted pre-made fibreglass sheets where tiles had been removed to ensure a flat, level surface.

An etching primer was then used on the walls and chemical-resistant GRP fibreglass was applied to both the walls and floor, coating the entire length of the gully. This provides a long-lasting, impact resistant channel where chemical runoff can travel safely.

For the perfect finish, we added a final resin top coat to make sure every surface was water-tight. Then we reinstalled all the pipework that had to be removed in order to perform the pit repair, insuring as little delay as possible for production.
