What is Pool Coping?
Pool coping is the material used to finish the top edge of your swimming pool and join it to the pool deck. It is a layer of material that runs around the outside of a pool and is used to add decoration or accents to the pool area.
It can sometimes be used to visually separate a patio or deck area from the pool or create an area for swimmers to relax in. To select a pool coping for your pool consider these factors. If an inground swimming pool is constructed of concrete or fibreglass it will need coping,
which is a capping stone for the edge of the pool shell. Besides simply being necessary, the coping provides an opportunity for a decorative accent, which can greatly enhance the overall appearance of the swimming pool. When someone in the swimming pool holds onto the edge, that’s the coping that they are grabbing onto. [Read more about – what is pool coping ?]
Coping is mounted on the bond beam, covering its concrete edges and concealing the steel projecting from the pool’s walls.
It also prevents water from getting behind the pool shell, and integrates the finish and tile of the swimming pool.
If coping is installed correctly, any water that is splashed out of the pool should flow away from the pool and down into deck drains. Coping should be tilted slightly away from the pool.
How To Select Pool Coping
Pool coping is a personal decision based on your preferences for your pool area. So, there is no right or wrong kind of coping, only what you like or don’t like.
If you or your family or guests plan to get in and out of your pool by climbing out over the coping, then a bull-nosed edge might make a better surface. If you enjoy a modern but timelessly elegant look, a cantilevered coping might be the best choice.
A rolled edge coping allows swimmers to grasp the edge of the pool with their feet/toes better, or to reach up and grab onto – something important to young or beginning swimmers. Look at each style and decide which looks best for your yard and pool. Consider cost as well.
Four Main Styles of Pool Coping
• Rolled edge or bullnose. Flat and smooth with a rounded edge at the end. Good for diving from, or for holding onto from inside the pool.
• Tumbled Edge or Mitred Edge. Flat surface with no sharp edges. Easy to get in and out of the pool by climbing over this edge.
• Cantilevered OR Drop Face. This coping runs out flat then drops at a 90-degree angle over the water in an L-shape. Classic and modern look. Not a coping you can climb out of the pool on. More cleanly decorative.
• Rough cut. Usually made from rock or stone, this coping is textured and natural or rustic looking, somewhat or not flat, and may or may not extend over the water. Better for creating a natural look around the pool, especially when created with stone.
Common Materials Used for Pool Coping
Sandstone is the most common and popular non slip stone material used for pool coping, closely followed by Bluestone and Travertine All are available in the four most common styles of coping (bull-nosed, drop face edge, tumbled edge or rough cut.
What material you choose depends on how you use your pool. When selecting your pool coping pick the style of coping and then check with your pool installation contractor to see what materials are available in that style.
What you NEED to know about selecting natural stone pool coping!
Summer is not far away, and some of us will be dreaming of sitting by the pool with a cool drink and a good book. On the other hand, some of us might be in the middle of a nightmare, looking at their stained, cracked or decaying paving.
Pools are no longer just a place for a ‘quick dip’; they are now often the centrepiece of outdoor entertaining, with the surrounding paving and landscaping just as important as the pool itself.
We are presented with a wide range of natural and engineered products for use as poolside paving. Selection is primarily based on aesthetics but determining fitness for purpose of the right product is important to maintain the desired appearance.
Your selection process (whether it be natural or engineered stone) should include a review of the five S’s.
Stain Resistance. Paving can be exposed to a wide range of staining agents. When it comes to entertaining poolside, red wine from spilt drinks is an obvious hazard along with oil from barbecues and foodstuffs. Tannin from fallen leaves and surrounding garden vegetation is also a potential source of staining.
You can reduce the risk of staining by selecting a paver that has a low absorption capacity. Stains can be more conspicuous on pavers with a uniform appearance (especially mid-tones) compared to material that is more highly figured. Most types of high density limestone, travertine, granite, slate and bluestone are effective at resisting stains.
Judicious use of an oil repellent impregnating sealer around high risk areas such as barbecues can help preserve the appearance of your stone.
Slip Resistance. Safety around the pool should include the installation of slip resistant paving. Most stone types can be prepared in a wide range of surface textures that are safe around a pool including sawn, grit blasted, flamed (exfoliated), and split face. DO NOT USE honed and factory filled travertine in ANY external areas open to getting wet on the surface (too slippery). The trapping of grime on rough texture surfaces can occur, but this can usually be handled with a hose and stiff bristled broom.
Salt Tolerance. Pool surrounds are an aggressive environment for paving as it is regularly exposed to salt or chlorine. Resistance to salt attack can be determined by Australian standard method AS/NZS 4456.10A. This method measures the weight loss of the stone after repeated immersion in a salt solution. Stone used as pool paving should have a maximum weight loss of 1%.
Granite, travertine, high density limestone and bluestone usually have very good salt resistance. Some types of slate and sandstone are also suitable for use. The use of a textured finish can hide minor surface decay.
It is also important to note that the incorrect use of sealers can lead to accelerated decay of poolside paving as it can trap salt within the stone.
Strength. It is important that the paving has adequate strength to withstand service loads in both dry and wet conditions. Sedimentary stone types such as sandstone and limestone can lose over 50% of its strength when wet.
Loss of strength can be accommodated in paving design. As an example, doubling the thickness of the paver increases the breaking load fourfold while use of square paving units also reduces the risk of breakage.
Stability. Frequent wetting and drying of pavers can lead to expansion and contraction of minerals within the stone which can lead to decay. Stone types that have a high clay content or contain expansive minerals such as some volcanic sandstones may cause the stone to be dimensional unstable. Long, thin pavers are at a greater risk of warping.
The inclusion of regular expansion joints at least every 4.5 metres and the use of rapid setting adhesives can reduce the risk of warping. Also please ensure there is an active expansion joint in the pool paving between the pool beam (coping tile) and the rest of the paving. Square paving units are usually more dimensionally stable than long rectangular units. Increasing the paver’s thickness also improves stability.
Hopefully, these selection criteria will help you in discussions with your stone merchant. When discussing your project with the supplier, it is important that you provide as much information as possible about your project. It is in your interest that the supplier fully understands what you need so they can provide you with a product that is fit for purpose. Remember the five S’s and enjoy your pool with peace of mind.
