Pond-Building

GRP (fiberglass) garden ponds are exceptionally durable and offer a natural, very beautiful look.

GRP pond new construction

In the past, also for cost reasons, polyester resins and glass mats were used. The film below therefore shows construction using boat-building polyester resin.

Since the ban on selling polyester resins containing styrene to end users, epoxy resins have been increasingly used. These are processed with glass fabric instead of glass mat. A longer processing time is available and, in addition, epoxy resins have better water resistance.

GRP pond refurbishment

Epoxy resins are particularly suitable for the renovation of existing GRP ponds. In addition to excellent water resistance, epoxy resins adhere very well to a wide variety of substrates, including old polyester resin pond shells. Prior sanding of the surfaces is necessary.

For indoor applications, we generally recommend epoxy resins, as they have low odor during processing. The finished parts also no longer have any odor of their own.
