Exteriors - GRP Coping

GRP Coping Our GRP Coping stones offer a lightweight durable alternative to traditional cast stone. Choose GRP copings where there is any danger of storm damage and injury to pedestrians.

Modern building legislation has put a greater emphasis on health and safety, and especially in areas where there is a potential risk of falling stone work.

House Martin GRP coping is manufactured in two parts, a tough base plate with a stone effect GRP top moulding above. These are designed to overlap the base plate and form a drip two both sides of your party (or Gable End) wall.

GRP Coping Where our GRP coping stones are used on a pitch they can either be supplied with pre-moulded stop ends, or alternatively with a "Kicker" detail that has one section to the pitch and the base kicking out on a horizontal plain.

On larger sites we also offer the option of loose stop ends to avoid any waste from cut down GRP coping lengths.

Whilst the majority of applications are twice weathered (see profiles below), we also offer once weathered GRP coping stones with external and internal 90° corners to match.

GRP Coping kicker Please ensure weather copings are installed so that the fall faces in towards your building or balcony. Home owners need to be discouraged from placing items on once weathered copings which may fall off and injury anyone below.

An inward facing weathering enhances the chances of loose items falling backwards rather than out towards bypassers.

GRP Coping 2WCP430 Our copings have been designed with a feature groove to mimic a cast stone appearance. Using RAL and BS colour charts we can provide copings that will match most Bath and Portland Stone colours. If you require assistance with a quotation please call us on 0845 838 1296, or send us your roof plans and elevation drawings.

In addition to our standard GRP copings we are now pleased to offer a new alternative.

Our GRP copings are a lightweight solution that suit many standard wall types, but with our new Silica coated polystyrene copings we are able to take on all manner of awkward sizes, and can even offer copings to suit curved gable ends.

Silica coated polystyrene copings Each "Coping Stone" is usually produced in a 1200mm length, and can be installed with cartridge based adhesives. The outer coating can be produced to match, Portland or Bathstone, or just a plain painted effect. Each piece has a polystyrene core, Polyurea base coat and whatever exterior finish the client requires. We generally recommend that clients order profiles that are 100mm wider than the wall which is being covered. We use this to recreate a drip similar to that found on cast stone alternatives.

Users can install the product knowing that it will offer similar longevity to a traditional stone equivalent, whilst reducing the risk of death or serious injury in the event of storm damage. Contractors will appreciate the fact that individual pieces can be easily cut on site with a hand saw, and that there is no risk of water ingress through hollow profiles and failed silicone joints.
