GRP Lining Services Ltd are the only UK company offering the total service for same day polyurethane foam and fibreglass lining.  From bare blocks to a fully insulated and 100% waterproof koi pond in the same day!

Our polyurethane foam lining system offers a speedy and simple alternative to rendering your koi pool in preparation for our quality fibreglassing system.

Please note our PU foam is not sprayed directly to your pool but is applied using semi rigid boards which can be sculpted to virtually any shape of pool.

The PU boards can be applied to damp walls totally eliminating the need to wait for render to dry out and then be fibreglassed. Pools with serious water ingress need specialist preparation that we are happy to advise about.

Window frames can be incorporated from the PU boards on the inside of the pool therefore dispensing with angle iron or aluminium framework for viewing windows. We can round the corners of your pool vertically and horizontally to aid water flow around your pool without using bricks or blockwork.

For a sample board of our GRP / PU foam system please enquire.

The majority of ponds we sealed in 2006, 2007, 2008 and 2009 were pre lined with 12mm PU tiles.

Please note we do not apply any of our grp lining systems to any DIY foam lined ponds i.e. Kingspan and Celotex.
