Fibreglass Application Frequently Asked Questions.

Can you apply the fibreglass to a rendered wall?

Absolutely. Please call us for information on how smooth the render needs to be in order to give you the highest quality finish.

How do I prepare my pond for the PU foam and pond fibreglassing stage, how do we book you and what are your requirements?

It is difficult to give a 'how to guide' that covers every pond as your pond is unique to any other but we hope you find this information helpful.

All we ask is you prepare a clean, accurately and truly built pond, erect a weatherproof cover for us to work under and around and to keep in touch with us as you continue your build so we can be there when you want us rather than have to wait for our diary to clear.

Here are the basics on how to get your pond ready for our koi pond fibreglassing service.

Install your bottom drain(s) flush with the concrete floor. Return pipes can be left proud by 1", 25mm and we'll grind them tight to the walls so they are 100% fish friendly. Your skimmer should be 15mm proud into the pond to accommodate our PU foam. We don't seal INTO the skimmers as we'll want to fit the skimmer face/skimmer guard for you thus creating an independant permanent seal.

The walls should be built as flat as possible with no blobs of mortar protruding because the fibreglass/foam lining follows the shape of anything it is applied to. We want to leave you with the smoothest finish available in the industry and this is achieved by working onto true surfaces. We don't employ the attitude of 'who cares? it will all be covered in algae soon enough'. We want to leave you with a product we are proud of.

Ideally your pond should be dry but when excavating to the depths seen on many koi ponds you may dig below the water table-we need to know if this happens well in advance of our attendance please. We'll gladly advise you on how to deal with this problem if happen to hit the water table.

Why do we need the pond covering for us to do our work?

The answer to this is twofold. The materials we use are intolerant of water (rain and ground water) before they are combined and cured (hardened) but once they harden you have the best waterproofing method known to date. Also they should never be installed under direct sunlight. A gardener may enjoy the sun on his back whilst working, the fibreglass specialist doesn't because they uv in sunlight adversely effects the curing times and can lead to problems with discolouration of the final topcoat.

Do I need to sand the fibreglass down and fill the pond several times before I introduce my fish?

An emphatic no to both questions. The fibreglass system you are buying is inert, non toxic to fish and will be perfectly safe. In saying this the final process of the flowcoat may on certain ponds be contaminated by insects, leaves and dust dependant upon the environment on the day of the grp installation. This is out of our control and we will leave you with clear instructions on how to deal with this during and after the fibreglass installation.

I have other questions and queries.

If you are unsure of anything whatsoever we are here to help and advise you. Please just ask anything you want and we'll be pleased to help.
