What is Pond Sealant?

Pond sealant is a barrier used to prevent the water loss from a pond. The leaking water can be blocked through various methods such as: sodium bentonite clay, polyurethane sealants, pond paints and bitumen paints. Each method of pond sealant is versatile and can be applied under certain situations.

Sodium bentonite clay pond sealant can be applied in either a granular or a powder form to the dry soil of the pond bottom during construction. This naturally occurring clay swells when it comes in contact with water. It seals tiny pores in the pond base and stops water from escaping. The clay is environmentally safe and economical. If a leak is suspected, clay granules can be sprinkled over the suspected leak area so they will swell and block the hole.

Polyurethane sealants are used to seal concrete, stone and brick materials used in building ponds. This method of pond sealant is easily applied with a brush or roller and will provide a durable, flexible seal. This type of sealant can be expensive if an entire pond needs to be coated, but it is an adaptable fix if a minor, non-structural leak in a concrete pond must be repaired. Polyurethane pond sealant can be used under damp and cool conditions and there are a number of colors available to match the existing color of the pond.

Pond paints are water-based epoxy resins that are easy to apply and come in a variety of colors. These sealants are used to provide a watertight seal to concrete, cement or mortar. As most people are now employing liners and natural-looking ponds, pond paints are used mostly to touch-up and repair existing water features. Applied with a brush or roller, the pond sealant paint is tolerant of damp applications. It usually dries in four to six hours and requires two applications.

Bitumen pond sealant is an inexpensive but messy way to seal a concrete pond. Bitumen sealant can be brushed or toweled into place. It has good adhering qualities, but must be applied to dry-cured concrete to ensure a proper seal. To avoid any contamination, it is important to choose bitumen that is to drinking water standards.

Excessive water seepage from ponds can be a serious problem. When considering establishing a water feature, it is important to include proper planning and investigate local regulations regarding installation requirements. Soil reports and site geology may indicate where and how the pond is to be constructed. Regular maintenance and proper construction using good techniques and quality materials can prevent seepage and promote the lifespan of the pond.
