Integral Concrete Colour

During manufacturing the GRC mixture can be coloured by blending mineral oxide pigments with either grey or white cement.

Our product collections are available in four standard colours: charcoal, concrete grey, white and kalgoorlie.

(Sandstone has been retired at a standard colour option, but can still be specified and ordered).

Please note that we do not recommend the use of dark mineral oxides, like charcoal, for outdoor seating. Dark surfaces can reach very high temperatures when placed in full sun.

Other mineral oxide colours are available on special request — refer to the CCS Colour Card.

Painted Colour, Special Effects & Finishes

Glassfibre Reinforced Concrete (GRC) lends itself to bespoke design and innovation, as custom design ideas can be modelled and moulded into functional public space pieces.

It can be coloured with mineral oxide pigments or painted to match virtually any colour and is easily moulded to reproduce shapes, reliefs and patterns to compliment any design theme.

Painted Colour

Our products can be painted to achieve virtually any colour. Typically we use high-quality exterior, low sheen, water-based acrylic paints to achieve your desired colour. Complimentary black Bitumen-based waterproofing is included.

Choose the colour you want, let us know the name and code and we’ll purchase the paints and apply it to your order.

Please note that we do not recommend painting seating units without timber tops or the use of dark mineral oxides, like charcoal, for outdoor seating. Dark surfaces can reach very high temperatures when placed in full sun.

Specialty Paints

We use specialised paints to achieve rust, copper and aged copper. Bridge paint (micaceous iron oxide paint) can also be applied to our products.

Choose the colour you want, let us know the name and code and we’ll purchase the paints and apply it to your order. Please note that we do not recommend painting seating units without a timber deck cover.

Pitted Surface

Some of our products can be manufactured with a pitted surface.

Additives are applied to the mould surface prior to spraying the GRC mixture into the mould. This creates a dimpled and pitted effect on the exterior product surface.

Patterned Surface

Should you need a special design or pattern moulded onto the product surface of a square or rectangular planter, we can assist with patterns available in the Reckli Formliner catalogue: Reckli Formliner.

Contact our sales team to discuss your preferred pattern to determine suitability before specifying.

Timber options

We use Tonka hardwood, also known as Southern Spotted, Cumaru or Brazilian Teak for all timber seating units (unless specified differently). Tonka is a kiln dried, Class 1, non-bleed hardwood and is ideal for structural and furniture applications.

Tonka hardwood is extremely hard and shock resistant, it also carries FSC100% Certification that it is sourced from legal and well-managed forests.

All timber is sealed with Equisol E365 oil with medium-brown tint (unless specified differently). We can also offer a clear non-tinted version upon request.

Tonka hardwood may be substituted with timber and sealant of your choice, please contact our sales team to determine suitability before specifying.

Feet & Castor Wheel Options For Planter Boxes

Planter Box Feet

Feet Options for Planter boxes

Our square and rectangular planter boxes come standard with 10 mm high strip feet cast into the base.

Depending on size, most planter boxes can also be customised with 25, 50 or 75 mm high block feet if added height is required.

Planter Box Castor Wheel

Castor Wheels for Planter boxes

If planters need to be able to be moved from time to time, we can fit castor wheels to the planter base.  Typically two of the four castors will have brakes built into them.

Not all planter-boxes are suitable for fitting castors, such as tall narrow planters or our large square planters. Please contact our sales team to discuss your requirements.

Waterproofing and Drainage

Our products come standard with clear Acrylic-based internal waterproofing and with drainage channels, holes and aids already installed. (Unless specified without). The location, size and number of drainage holes relate to the size of the planter and its soil volume.

For more information on our drainage aids, including a planting guide, please download our Drainage Guide.

WATERPROOFING

Quatro Design planters come standard with complimentary clear Acrylic-based internal waterproofing.

Black Bitumen-based internal waterproofing membrane can be added at an additional cost, and is best suited for use when our products are converted into water features. A non-toxic and fish-safe waterproofing option is also available.

DrainEZE Drainage Screen

DRAINEZE DRAINAGE HOLE SCREEN

DrainEZE drainage hole screens are fitted to all of our smaller pots and planters and are included in the price. This device (patent pending) is a conical dome with vertical openings to enable water to pass into an air chamber above the drainage hole, this increases the area through which the water can pass compared to the drainage hole by itself.

The DrainEZE drainage hole screen is covered by a thin layer of Geofabric filterwrap, and secured at the top with a press-on clip to prevent the pot drainage hole from blocking whilst still allowing water and fine particles to pass through.

DRAINAGE CELL

VersiFlex flexible drainage cells are fitted to our large and over-sized pots and planters. These interlocking drainage cells are designed for use in planter boxes, roof gardens and retaining walls. Their open surface design and high internal void volume enable the rapid capture and transport of water volume to result in efficient drainage.

The Drainage Cells are covered by a thin layer of Geofabric filterwrap to prevent the drainage hole from blocking whilst still allowing water and fine particles to pass through.

Drainage Regulator Riser

DRAINAGE REGULATOR RISER

Drainage Regulator Risers are often installed when the amount of water draining from the base of the pot should be limited. They create an approximate 60 mm high water reservoir at the base of the pot to prevent excess water from draining away.

The Drainage Regulator Riser is covered by a thin layer of Geofabric filterwrap to prevent the drainage hole from blocking whilst still allowing water and fine particles to pass through.

Custom Project Design & Manufacture

The creation of bespoke pieces is one of the most rewarding aspects of what we do. Glassfibre Reinforced Concrete’s (GRC) ability to be shaped and moulded into virtually any shape and size brings creative freedom and endless design possibilities to public space design.

We partner with you to collaboratively resolve your design vision and custom project and product concepts. Our design team work through your drawings and specifications and can provide guidance on the parameters of mould-making and manufacturing with GRC. They can also produce two or three dimensional drawings to help you envision the final product.

The specifications of some of our existing product ranges can also be modified to suit your project requirements.

Please contact our team to discuss your next project.
