Pool coping materials – choosing the right material for your pool
Before you choose the material for your pool coping you need to consider some major criteria that it has to meet – durability, safety, comfort, visual appeal. Remember that the pool coping material has to work harmoniously with the pool deck, the pool interior and the overall exterior style. In addition, it is essential that the material is resistant to cleaning agents like chlorine, acids or in the case of a salt pool – salt. Some materials get hot quite easily and may be unpleasant to bare feet, which is also an important issue to consider.
Concrete pool coping options
Concrete pool coping comes in two major varieties – poured concrete coping which is poured in place and precast concrete pool coping. The advantage of concrete coping is that it can easily fit any style and is the most affordable option compared to natural stone, tile, etc.
Poured concrete coping vs precast concrete pool coping – what is important to know?
Poured concrete is an option involving the use of a mold which is placed all around the edge of the pool. The cement is poured on site giving the coping a seamless appearance. Poured concrete is solid and durable and you can choose a variety of colors to match the coping with your pool deck as well as the type of coping edge – flat edge, bullnose, curved edge, etc. Experts recommend poured concrete pool coping when you want smaller pools to appear larger. However, installation is expensive and laborious. Installing the coping requires workers, equipment and in general, is not a DIY project. Sealing the poured concrete coping after installation is strongly recommended.
Precast concrete pool coping comes in pre-fabricated blocks and you can choose from a variety of textures, patterns and colors. This is the least expensive option as you can buy them and install the pieces around the pool using mortar and caulking between individual sections. Unlike poured concrete, where the color is uniform, you can combine pre-cast concrete coping units in different colors and give you more design opportunities. This option is more suitable for a DIY project as it does not require any special equipment. You have to seal the coping with a weatherproof, pH neutral sealant.

Choosing among the variety and the decision which stone to use depends entirely on the pool owner, his personal preferences or color, texture, visual aesthetics and the overall color scheme of the project. For example, limestone, travertine and almond granite are a good choice for projects in warmer color shades, while silver travertine, silver marble or granite will work well in the gray-ish color palette.
Travertine coping is a popular choice as the material is valued for remaining cool to the touch and the variety of color options. It comes in various shades of light brown, brown and gold or ivory. Travertine is very porous and tends to absorb water instantly, so when used as pool coping, it should be sealed.
Limestone is a beautiful material used not only for pool coping but for patio and pool decks. It is durable and will retain its spectacular appearance for many years. In terms of color options, travertine can be found in gray, blue, tan, brown shades. Another reason for the great popularity of limestone is that it is easily cut in shapes and sizes.
Sandstone is very hard wearing as it is comprised of quartz grains. It adds color and texture to the pool design, it is durable and reliable, anti-slip and salt-tolerant. The resemblance to sand makes sandstone a great choice for swimming pool coping, pool decks and outdoor covering.
Slate is another option for pool coping. It is installed easily and can be cut in varying lengths and widths which makes it popular among pool builders and designers. Slate is durable and comes in many color shades – from dark gray and black to brown, red, green, blue-gray, etc.
